Question 1Water Well Standards and Contractors' Licensing Program

Under the Nebraska Well Standards, a water well contractor must file the well registration/log with the state within what period after completing construction of a well?

  1. Within 30 days after completion of the well Correct answer.
  2. Before any drilling begins on the site
  3. Within 6 months of the well's completion
  4. Only when the property is sold

Explanation

Nebraska requires the water well contractor to submit the well log/registration to the state within 30 days after the well is completed. This allows the state to maintain a current record of groundwater use and well construction. Filing before drilling or waiting until a sale does not satisfy the deadline.

Question 2Water Well Standards and Contractors' Licensing Program

In Nebraska, which of the following activities requires a license as a water well contractor?

  1. Replacing a pressure tank on an existing well system
  2. Testing the pH of an existing well's water
  3. Drilling and constructing a new domestic water well Correct answer.
  4. Inspecting a well for a real estate transaction

Explanation

Constructing a water well, including a domestic well, is regulated activity that requires licensure as a water well contractor in Nebraska. Water testing, pump/pressure component work, and inspection are not the construction of a well and do not themselves require a well contractor license.

Question 3Water Well Standards and Contractors' Licensing Program

What is the primary purpose of the annular seal (grout) placed between the well casing and the borehole wall?

  1. To prevent surface and shallow groundwater contamination from moving down along the casing Correct answer.
  2. To keep the casing from being pulled out during development
  3. To support the weight of the pump column
  4. To increase the pumping rate of the well

Explanation

The annular seal creates a barrier that blocks contaminated water from the surface or shallow zones from traveling down the outside of the casing into the producing aquifer. It does not increase yield or carry structural loads. Proper sealing protects the groundwater resource and public health.

Question 4Water Well Standards and Contractors' Licensing Program

A well is completed with the casing terminating above the ground surface. Which term describes this completion type under Nebraska well standards?

  1. A pitless completion
  2. An above-grade completion Correct answer.
  3. A below-grade (buried) completion
  4. A flowing artesian completion

Explanation

When the casing extends above the ground surface, the well is described as an above-grade completion, which helps keep surface water away from the well opening. A pitless adapter is a device that allows the discharge pipe to pass below frost line while the casing remains above grade. Flowing artesian refers to pressure conditions, not casing height.

Question 5Water Well Standards and Contractors' Licensing Program

Nebraska's licensing program for water well contractors is administered by which state entity?

  1. The Department of Health and Human Services alone
  2. The Department of Transportation
  3. The Department of Natural Resources (DNR) Correct answer.
  4. The Game and Parks Commission

Explanation

The Nebraska Department of Natural Resources administers the water well contractor licensing and well standards program. DNR maintains well logs and enforces construction standards. Other agencies may have related roles, but DNR is the licensing authority.

Question 6Water Well Standards and Contractors' Licensing Program

Before a new water well is placed into service, the contractor should disinfect the well. What is the standard purpose of this disinfection?

  1. To increase the well's static water level
  2. To remove dissolved iron from the groundwater
  3. To sanitize the well and distribution system and reduce bacterial contamination introduced during construction Correct answer.
  4. To soften hard water before it reaches the fixtures

Explanation

Disinfection with a chlorine solution sanitizes the well and piping after construction, addressing bacteria that may have entered during drilling and installation. It does not soften water, remove iron, or change water levels. A follow-up bacteriological test verifies the result.

Question 7Water Well Standards and Contractors' Licensing Program

Which of the following best describes a 'pitless adapter' in a well installation?

  1. A device that seals the bottom of the well to prevent sand entry
  2. A cap placed on top of the casing to keep out insects
  3. A tool used to measure the static water level
  4. A fitting that allows the discharge pipe to pass through the casing below frost line while keeping the casing head above grade Correct answer.

Explanation

A pitless adapter provides a watertight connection through the casing so the service line exits below the frost line, protecting it from freezing while the casing remains above grade. It is not a bottom seal, a measuring tool, or a well cap. This design is common in cold-climate states like Nebraska.

Question 8Water Well Standards and Contractors' Licensing Program

Nebraska well standards require that the well casing extend a minimum distance above the ground surface or floor to prevent surface water entry. Which value reflects the typical minimum above-grade casing height?

  1. Flush with the ground surface
  2. At least 6 feet above the ground surface
  3. At least 3 inches above the ground surface
  4. At least 12 inches above the ground surface Correct answer.

Explanation

Nebraska standards generally require the casing to extend at least 12 inches above the ground surface (or above the floor in a pit) to keep surface water and contaminants from entering the well. Flush or very low casing does not provide adequate protection. Excessive height is not required.

Question 9Water Well Standards and Contractors' Licensing Program

A contractor plans to grout the annular space of a well. Which method is commonly accepted for placing grout to ensure a continuous seal?

  1. Dumping bentonite pellets loosely from the top
  2. Pumping grout from the bottom of the annular space upward through a tremie pipe Correct answer.
  3. Filling the annulus with drill cuttings
  4. Pouring dry cement from the surface into the annulus

Explanation

Pumping grout from the bottom up through a tremie pipe displaces water and prevents voids or bridging, producing a continuous seal. Surface pouring, loose pellets, and drill cuttings can bridge or leave gaps and are not accepted as a proper annular seal. A continuous, verified seal is required to protect groundwater.

Question 10Water Well Standards and Contractors' Licensing Program

During construction, a contractor encounters an unregistered abandoned well on the property. What is the appropriate action under Nebraska well standards?

  1. Ignore it because it predates the current project
  2. Connect it to the new well to increase capacity
  3. Decommission (properly plug and seal) the abandoned well according to standards Correct answer.
  4. Fill it with sand and leave the casing in place

Explanation

Abandoned wells must be properly decommissioned by plugging and sealing them per state standards to prevent contamination pathways and safety hazards. Filling with sand or leaving the casing does not satisfy decommissioning requirements. Connecting an unregistered well is not an acceptable substitute.

Question 11Water Well Standards and Contractors' Licensing Program

A well log submitted to the state must accurately describe the well. Which set of items is required on a Nebraska well log?

  1. Only the driller's name and the date
  2. Owner name, location, well depth, casing size and depth, screen/open interval, and static water level Correct answer.
  3. Only the property tax parcel number
  4. Only the pumping rate and the pump brand

Explanation

A well log documents the construction details needed for the state's groundwater records: owner and location, total depth, casing dimensions and depth, screen or open interval, water level, and grout/seal information. Minimal entries such as just a name or pump brand do not fulfill the reporting requirement. Accurate logs support resource management and future well work.

Question 12Water Well Standards and Contractors' Licensing Program

A contractor is setting casing through a shallow gravel layer that could transmit contaminated water. What design element is most important to protect the producing aquifer?

  1. An open hole with no casing through the gravel
  2. A larger pump to draw water faster
  3. A shorter casing string that stops above the gravel layer
  4. A properly sized and placed annular seal extending through and below the contaminated zone Correct answer.

Explanation

The annular seal must extend through the contaminated zone and into an impermeable formation to block vertical migration of poor-quality water along the casing. Stopping casing above or leaving an open hole would create a pathway. Pump size does not address contamination.

Question 13Water Well Standards and Contractors' Licensing Program

A domestic well is being developed after drilling. Which practice best indicates that development is complete and the well is producing clear water?

  1. Pumping until the discharge runs clear of drill cuttings and fines at a stable rate Correct answer.
  2. Adding sand to the annulus to filter the water
  3. Water remains turbid with fine sediment after extended pumping
  4. Stopping development as soon as water first appears

Explanation

Development removes drilling fluids, cuttings, and fines from the screen and surrounding formation. Completion is indicated when discharge runs clear at a stable rate. Persistent turbidity suggests incomplete development or a screen/aquifer problem. Adding sand is not a development method.

Question 14Water Well Standards and Contractors' Licensing Program

Which condition would most likely require the contractor to install a larger or more carefully sized screen/open area in a well completed in a sand-and-gravel aquifer?

  1. The aquifer material is fine-grained and uniform sand Correct answer.
  2. The aquifer is a fractured limestone with large openings
  3. The static water level is deep
  4. The casing is steel rather than PVC

Explanation

Fine, uniform sand requires careful screen sizing (slot size matched to grain size) and adequate open area to prevent sand entry while allowing flow. Fractured rock needs little or no screen. Water level depth and casing material are not the primary drivers of screen open-area sizing for sand control.

Question 15Water Well Standards and Contractors' Licensing Program

A contractor's license under Nebraska's water well program is best described as which of the following?

  1. A one-time permit that never expires
  2. A required credential to lawfully engage in water well construction, with renewal and continuing education obligations Correct answer.
  3. A voluntary certification with no legal effect
  4. A federal license issued by the EPA

Explanation

Nebraska requires a license to lawfully construct water wells, and licenses carry renewal requirements and continuing education to maintain competency. It is not voluntary, does not last indefinitely, and is a state rather than federal credential. Operating without a valid license can result in enforcement action.

Question 16Water Well Standards and Contractors' Licensing Program

A well is to be completed as a flowing artesian well. Which control measure is most appropriate to manage the flow at the surface?

  1. Reduce the casing diameter to stop the flow
  2. Leave the casing open so the water can flow freely
  3. Backfill the annulus with gravel to relieve pressure
  4. Install a watertight cap or control valve and seal the annulus to contain pressure Correct answer.

Explanation

Flowing artesian wells require a pressure-tight cap or control valve and a properly sealed annulus to control and contain the flow, preventing waste and contamination. Leaving the well open wastes water and creates hazards. Gravel backfill or a smaller casing does not control artesian pressure.

Question 17Water Well Standards and Contractors' Licensing Program

Which practice is required when a well is temporarily not in use but is intended for future service?

  1. Fill the casing with surface runoff
  2. Abandon it immediately with no record
  3. Maintain a secure, watertight cap and keep the well protected from contamination until it is used or formally decommissioned Correct answer.
  4. Remove the cap to allow ventilation

Explanation

A well intended for future use must remain protected with a secure, watertight cap and be maintained against contamination. Removing the cap or introducing surface water creates a direct contamination pathway. If the well will not be used, it must be formally decommissioned.

Question 18Water Well Standards and Contractors' Licensing Program

A contractor is asked to deepen an existing well. Which consideration is most important before proceeding?

  1. Skipping the well log because it is a modification
  2. Assuming the existing casing can support any depth
  3. Confirming the existing casing, seal, and well log so the deepened interval can be properly constructed and recorded Correct answer.
  4. Adding a larger pump before deepening

Explanation

Deepening a well requires evaluating the existing casing, seal integrity, and log so the new interval is constructed to standards and the modification is properly recorded. Assuming casing adequacy or skipping documentation can compromise the well and violate reporting rules. Pump changes do not address construction requirements.

Question 19Water Well Standards and Contractors' Licensing Program

What is the purpose of a sanitary seal (well cap) on a completed well?

  1. To increase the pressure in the distribution system
  2. To measure the pumping rate
  3. To support the pump motor
  4. To prevent insects, surface water, and debris from entering the casing while allowing proper venting Correct answer.

Explanation

A sanitary seal or well cap closes the top of the casing against insects, surface water, and debris while providing a vent to prevent pressure buildup. It does not boost system pressure, measure flow, or support the pump. A proper seal is a key barrier protecting well water quality.

Question 20Water Well Standards and Contractors' Licensing Program

A contractor observes that grout placement in a deep annulus may have bridged, leaving a void behind the casing. What is the most appropriate response?

  1. Proceed because the well will be disinfected later
  2. Add gravel to the annulus to fill the void
  3. Re-establish a continuous seal by re-grouting the affected interval before completing the well Correct answer.
  4. Cover the void with a well cap and ignore it

Explanation

A bridged grout column leaves a void that can transmit contamination along the casing; the seal must be re-established before the well is completed. Disinfection does not repair a physical pathway, and covering or gravel-filling the void does not create a proper seal. Verifying a continuous seal is essential to groundwater protection.

Question 21Water Well Standards and Contractors' Licensing Program

A contractor is evaluating whether a proposed well location meets Nebraska setback expectations. Which factor is most directly relevant to protecting the well from contamination?

  1. The brand of the pump to be installed
  2. The owner's preferred landscaping style
  3. Distance from sources such as septic systems, livestock areas, and chemical storage Correct answer.
  4. The color of the well casing

Explanation

Well location setbacks from potential contamination sources such as septic systems, animal confinement, and chemical storage are the key siting consideration for protecting water quality. Casing color, pump brand, and landscaping do not affect contamination risk. Proper siting works together with a good annular seal.

Question 22Water Well Standards and Contractors' Licensing Program

A contractor must decide between a screened completion and an open-hole completion in a consolidated sandstone aquifer. Which reasoning best supports the choice?

  1. The choice depends only on the driller's preference
  2. Open hole is chosen because it prevents all sand entry
  3. Screened completion is always required regardless of formation
  4. Open hole is preferred in competent consolidated rock, while screening is used where the formation would produce sand Correct answer.

Explanation

In competent consolidated rock, an open-hole completion allows water to enter without a screen, while screens are used in unconsolidated or sand-producing formations to control sediment. Screens are not universally required, and open hole does not guarantee sand-free water. Formation characteristics, not preference alone, drive the design.

Question 23Water Well Standards and Contractors' Licensing Program

A contractor is reviewing whether a pump setting is appropriate. The static water level is 40 feet and the pumping water level is 90 feet during a test. Which setting consideration is most important to avoid pumping the well dry?

  1. Set the pump at the static water level
  2. Set the pump above the static water level
  3. Set the pump intake below the pumping water level with adequate submergence and above the screen/open interval top Correct answer.
  4. Set the pump at the very bottom of the well

Explanation

The pump intake should be placed below the pumping water level with enough submergence to avoid breaking suction or cavitation, while staying above the producing interval to avoid drawing sand. Setting at or above static level risks running dry, and placing it at the very bottom can draw sediment. Design considers both drawdown and screen position.

Question 24Water Well Standards and Contractors' Licensing Program

A contractor is asked to seal the annular space of a well that penetrates a confining layer separating a shallow aquifer from the producing aquifer. Which outcome is the primary goal of sealing through the confining layer?

  1. Isolating the producing aquifer from the shallow aquifer to prevent cross-contamination Correct answer.
  2. Reducing the cost of the pump
  3. Making the well easier to drill
  4. Increasing the yield by connecting both aquifers

Explanation

Sealing through the confining layer isolates the producing aquifer from shallow, potentially poorer-quality water, preventing cross-contamination between aquifers. Connecting aquifers is the opposite of the goal. Cost and drilling ease are not the purpose of the seal. Aquifer isolation is a core groundwater protection principle.

Question 25Water Well Standards and Contractors' Licensing Program

A contractor must decide how to handle drill cuttings and drilling fluids at a site. Which practice best aligns with environmental protection expectations under Nebraska well standards?

  1. Discharge all fluids directly into a nearby ditch
  2. Bury cuttings around the wellhead
  3. Contain and dispose of cuttings and fluids in an approved manner that prevents them from entering the well or surface water Correct answer.
  4. Leave cuttings on the ground next to the casing

Explanation

Drilling fluids and cuttings must be contained and disposed of in an approved manner to prevent contamination of the well and surface water. Discharging to a ditch, burying around the wellhead, or leaving cuttings beside the casing can pollute water and violate environmental requirements. Proper containment protects both groundwater and surface resources.

Question 26Water Well Standards and Contractors' Licensing Program

Under Nebraska's water well standards, which individual must hold a water well contractor license before constructing a well for another person?

  1. Any person who drills, constructs, or installs a water well for compensation Correct answer.
  2. Only persons who install submersible pumps in existing wells
  3. Only persons who perform pump repairs on domestic wells
  4. Any person who owns more than one irrigation well

Explanation

The licensing requirement attaches to the business of constructing water wells for compensation, so anyone hired to drill or construct a well must hold the contractor license. Pump installation and repair on existing wells are generally handled under separate pump installer provisions, not the contractor license itself.

Question 27Water Well Standards and Contractors' Licensing Program

A licensed well contractor's license is issued for a defined period. What must the contractor generally do to keep the license active?

  1. Reapply as a new applicant each year with a new exam
  2. Renew before expiration and pay the required fee Correct answer.
  3. Post the license at each well site instead of renewing
  4. Notify only the well owner of continued operation

Explanation

Licenses run for a fixed term and must be renewed with the required fee before they lapse. Continuing to operate on an expired license exposes the contractor to enforcement action.

Question 28Water Well Standards and Contractors' Licensing Program

A contractor is submitting the required well log after completing a domestic well. Which statement best describes the log's role in the state program?

  1. It documents construction details so the state maintains a permanent record of the well Correct answer.
  2. It serves as the owner's proof of payment for the drilling contract
  3. It replaces the need for a sanitary seal on the completed well
  4. It is optional when the well is for single-family use

Explanation

The well log is a construction record filed with the state so that a permanent, retrievable history of the well exists for future owners, regulators, and drillers. It is a reporting requirement, not a substitute for proper well completion.

Question 29Water Well Standards and Contractors' Licensing Program

A contractor is preparing to grout the annular space of a newly drilled well. Which practice best supports a continuous, competent grout seal?

  1. Backfilling the annulus with drill cuttings before grouting
  2. Waiting several days after casing is set to begin grouting
  3. Dumping dry cement into the annulus from the top
  4. Placing grout from the bottom of the annulus upward as a continuous column Correct answer.

Explanation

Grout should be placed so the annulus fills from the bottom up as a continuous column, which displaces drilling fluid and limits voids or bridging. Top-dumping or backfilling with cuttings prevents a proper seal.

Question 30Water Well Standards and Contractors' Licensing Program

A contractor is reviewing a proposed well location near a septic system's absorption field. Which factor is most directly governed by the state's minimum setback requirements?

  1. The vertical depth of the well below the static water level
  2. The pump horsepower needed to meet peak demand
  3. The diameter of the well casing selected for the pump
  4. The horizontal distance between the well and the potential contamination source Correct answer.

Explanation

Setback requirements are horizontal separation distances between a well and contamination sources such as septic systems, lagoons, or fuel storage. Depth, casing diameter, and pump sizing are design matters, not setback distances.

Question 31Water Well Standards and Contractors' Licensing Program

A contractor is completing a well in a confined aquifer where the water level rises above the top of the aquifer but below land surface. How should this well be classified?

  1. A flowing artesian well
  2. A dry hole requiring abandonment
  3. A water-table well
  4. A non-flowing artesian well Correct answer.

Explanation

A confined aquifer whose potentiometric surface stands above the aquifer top but below land surface produces a non-flowing artesian well. If the potentiometric surface were above land surface, the well would flow without pumping.

Question 32Water Well Standards and Contractors' Licensing Program

A contractor is installing a pitless adapter on a well with a buried discharge line. What is the primary function of this device?

  1. It prevents the pump from running dry during low-water conditions
  2. It meters the volume of water withdrawn from the well
  3. It provides a below-frost-line connection that allows the pump to be serviced without digging up the line Correct answer.
  4. It seals the top of the casing against surface water entry

Explanation

A pitless adapter makes the connection between the drop pipe and the buried service line below the frost line, so the pump and drop pipe can be pulled for service without excavating. The well cap, not the adapter, seals the casing top.

Question 33Water Well Standards and Contractors' Licensing Program

A contractor is developing a new screened well in a sand and gravel aquifer. Which observation best indicates that development has achieved its purpose?

  1. The discharge runs clear of fines and the well yields steadily at a stable specific capacity Correct answer.
  2. The pump begins to surge repeatedly and discharge muddy water
  3. The casing begins to settle noticeably at the surface
  4. The static water level rises above the land surface

Explanation

Development removes drilling fines and rearranges formation material near the screen so water enters freely. Clear discharge and a stable, improving specific capacity show that the near-well zone has been cleaned.

Question 34Water Well Standards and Contractors' Licensing Program

A contractor must seal an abandoned well that penetrates multiple aquifers. Which approach best protects groundwater?

  1. Fill only the upper ten feet of casing with soil
  2. Fill the entire well bore with an approved sealing material placed to prevent cross-connection between aquifers Correct answer.
  3. Cap the casing at land surface and leave the bore open below
  4. Remove the casing and allow the bore to collapse naturally

Explanation

Abandonment sealing must isolate aquifers and prevent water from moving between them through the well bore. Approved sealing material placed through the full length of the bore accomplishes that; a surface cap alone does not.

Question 35Water Well Standards and Contractors' Licensing Program

A contractor is preparing to place a well screen in a fine sand aquifer. Which screen selection consideration is most important for controlling sand entry while maintaining yield?

  1. Selecting screen length equal to the full saturated thickness regardless of aquifer uniformity
  2. Matching the screen slot size to the grain-size distribution of the formation Correct answer.
  3. Choosing the largest available slot size to maximize open area
  4. Using the same screen specification as a nearby gravel aquifer well

Explanation

Screen slot size should be matched to the formation gradation, often with a filter pack, so the well produces sand-free water without excessive head loss. Oversized slots admit formation material and cause sand pumping.

Question 36Water Well Standards and Contractors' Licensing Program

A contractor is deepening an existing well to reach a deeper aquifer. Which consideration is most important before work begins?

  1. Whether the well log can be filed after the work is complete
  2. Whether the owner can pay for the additional drilling in advance
  3. Whether the existing pump is still under warranty
  4. Whether the existing casing and seal can be extended and the deeper aquifer isolated from upper aquifers Correct answer.

Explanation

Deepening can create a pathway between aquifers if the casing and annular seal are not extended to isolate the new production zone. The contractor must plan the casing and sealing before drilling deeper.

Question 37Water Well Standards and Contractors' Licensing Program

A contractor is installing a well for a public water system and must confirm the casing meets the program's minimum thickness and weight requirements. Which document is the most direct source for those specifications?

  1. The driller's personal field notes from prior jobs
  2. The adopted state water well standards and construction regulations Correct answer.
  3. The owner's utility bill history
  4. The manufacturer's pump performance curve

Explanation

Casing material specifications are set in the adopted water well standards and regulations, which govern construction requirements. Manufacturer curves and field notes do not establish regulatory minimums.

Question 38Water Well Standards and Contractors' Licensing Program

A contractor must decide how to handle water used for drilling a well in an area with shallow contamination. Which practice best protects the well during construction?

  1. Use water from the well being drilled once it begins producing
  2. Store drilling water in an open pit next to the wellhead
  3. Recirculate water from a nearby ditch to conserve supply
  4. Use water from a potable source and keep drilling equipment and tools clean Correct answer.

Explanation

Drilling water and equipment that contact the bore can introduce contamination, so potable water and clean tools are used to protect the well during construction. Using questionable water or open pits near the wellhead increases the risk of introducing contaminants.

Question 39Water Well Standards and Contractors' Licensing Program

A contractor is evaluating whether a well can be completed as an open-hole well in a consolidated sandstone aquifer. Which condition most favors an open-hole completion over a screened completion?

  1. The aquifer is a thin layer of fine unconsolidated silt
  2. The well must produce sand-free water from a poorly sorted gravel
  3. The formation is loose sand that collapses readily
  4. The formation is well cemented and stable enough to stand unsupported Correct answer.

Explanation

Open-hole completion works where rock is competent enough to remain stable without casing or screen across the producing interval. Unconsolidated or poorly sorted material tends to collapse or produce sand, favoring a screened or gravel-packed design.

Question 40Water Well Standards and Contractors' Licensing Program

A contractor is placing a bentonite grout seal in a deep annulus and is concerned about bridging. Which practice best reduces the risk of an incomplete seal?

  1. Adding sand to the grout to increase its weight
  2. Placing grout only above the static water level
  3. Pouring grout rapidly from the surface to save time
  4. Pumping grout through a tremie pipe from the bottom of the annulus upward at a controlled rate Correct answer.

Explanation

Tremie placement from the bottom up keeps the grout column continuous and displaces drilling fluid, which limits bridging and voids. Rapid top-pouring, sand bulking, or partial-depth placement can leave unsealed intervals.

Question 41Groundwater Well Registration

Under Nebraska well registration rules, who is required to file a registration for a new water well that will be used to withdraw groundwater?

  1. The licensed driller who constructs the well, on behalf of the owner Correct answer.
  2. Only the landowner, and only if the well exceeds 50 feet in depth
  3. The local natural resources district, after the well is finished
  4. Only the pump installer who completes the well

Explanation

Nebraska law places the registration duty on the licensed well driller who constructs the well, and the driller files the registration on behalf of the owner. The filing is tied to construction of the well rather than to pump installation or district action. Depth alone does not shift the filing responsibility to the landowner.

Question 42Groundwater Well Registration

A driller completes a new irrigation well in Nebraska. Within what timeframe must the well registration be filed with the appropriate natural resources district?

  1. Within 6 months after the well is completed Correct answer.
  2. Within 60 days after the first irrigation season
  3. Within 30 days after the well is completed
  4. Before the pump is installed but no deadline applies to the drilling

Explanation

Nebraska requires the driller to file the well registration with the natural resources district within 30 days after completion of the well. Completion, not pump installation or first use, starts the clock. A six-month window is too long and does not match the statutory deadline.

Question 43Groundwater Well Registration

Which item is a required piece of information on a Nebraska groundwater well registration form?

  1. The estimated yield of the aquifer at the site
  2. The brand name of the pumping equipment to be installed
  3. The driller's personal Social Security number
  4. The location of the well by quarter-section and tract description Correct answer.

Explanation

Registration forms require identification of the well location, typically by quarter-section, section, township, and range, along with owner and driller information and well details. Personal identifiers such as a Social Security number are not a registration requirement. Pump brand and estimated aquifer yield are not standard registration data fields.

Question 44Groundwater Well Registration

A driller registers a well and later discovers the recorded static water level was transcribed incorrectly. What is the appropriate action?

  1. File an amended registration with the natural resources district correcting the error Correct answer.
  2. Leave the record as filed because registrations cannot be changed
  3. Wait until the well is abandoned and note the correction then
  4. Report the error only to the well owner and take no filing action

Explanation

Registration records may be corrected by filing an amendment with the natural resources district that holds the original record. The district maintains the official file, so the correction must go through that office. Simply telling the owner or waiting until abandonment leaves an inaccurate public record.

Question 45Groundwater Well Registration

What is the primary purpose of Nebraska's groundwater well registration program?

  1. To set the price of water sold from irrigation wells
  2. To create a public record of wells and their groundwater use for resource management Correct answer.
  3. To license pump installers separately from drillers
  4. To guarantee every registered well will produce adequate water

Explanation

Well registration establishes a public inventory of wells and their use so natural resources districts and the state can manage groundwater resources. Registration documents location, use, and construction details; it does not guarantee yield or set water prices. Pump installer licensing is a separate regulatory matter.

Question 46Groundwater Well Registration

A property changes ownership after a well has been registered. What effect does the sale have on the existing well registration?

  1. The driller must re-register the well within 30 days of the sale
  2. The registration remains on file and the new owner should update ownership information Correct answer.
  3. The registration is void and a new well must be drilled
  4. The registration automatically transfers only if the pump is replaced

Explanation

A registered well stays in the district's records when the property is sold; the record follows the well, not the owner. The new owner should ensure ownership information is updated so notices and correspondence reach the right party. A sale does not require drilling a new well or re-registering the well itself.

Question 47Groundwater Well Registration

Which wells are generally exempt from Nebraska groundwater well registration requirements?

  1. Irrigation wells completed in the High Plains aquifer
  2. Domestic wells serving a single-family residence Correct answer.
  3. Wells used for livestock watering on a feedlot
  4. Municipal wells serving more than 25 connections

Explanation

Nebraska exempts certain small domestic wells, such as those serving a single-family household, from the standard registration requirement. Irrigation, municipal, and most livestock or commercial wells are subject to registration. The exemption is narrow and tied to domestic use rather than to aquifer or yield.

Question 48Groundwater Well Registration

On a Nebraska well registration, the term 'static water level' refers to which measurement?

  1. The depth to water while the pump is operating at design capacity
  2. The height of the pump column above land surface
  3. The total depth of the borehole from land surface
  4. The depth to water in the well when the pump is not running and the level has stabilized Correct answer.

Explanation

Static water level is the stabilized depth to water measured when the well is at rest and not being pumped. It is distinct from pumping level, which is drawn down during operation. Total borehole depth and pump column height are separate construction measurements.

Question 49Groundwater Well Registration

A driller completes a well on March 3 and mails the registration to the natural resources district on March 25. Which statement best describes the status of the filing?

  1. It is late because the deadline is 10 days after completion
  2. It is timely only if the district receives it before the pump is started
  3. It is timely because it was filed within 30 days of completion Correct answer.
  4. It is late because registration must be filed before drilling begins

Explanation

The filing window runs from completion of the well, and a filing made within 30 days of completion satisfies the requirement. Pre-drilling filing is not required, and no 10-day deadline applies. Starting the pump does not control the timeliness of registration.

Question 50Groundwater Well Registration

A driller registers a well but must report the primary use. Which pairing of use code and description is correct for a well that supplies a center-pivot irrigation system?

  1. Industrial use
  2. Public water supply use
  3. Domestic use
  4. Irrigation use Correct answer.

Explanation

A well supplying a center-pivot system is registered under irrigation use, which is the standard category for agricultural crop watering. Domestic use covers household supply, industrial covers manufacturing or processing, and public water supply covers municipal or community systems. Correct use coding affects how the district tracks groundwater withdrawals.
