32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Title 178 NAC 10
- Nebraska administrative rule containing water well construction standards: casing, grouting, sealing, wellhead, and abandonment requirements enforced by the Department of Environment and Energy.
- Licensed water well contractor
- A person or business holding a Nebraska license authorizing contracting for well construction; wells must be drilled and reported under an active license number.
- Annular seal
- The grouted space between the borehole wall and casing, installed to prevent surface water and shallow contaminated groundwater from moving down along the casing.
- Tremie grouting
- Placing grout from the bottom of the annular space upward through a pipe so the seal fills continuously without voids, bridging, or dilution.
- Well completion report
- The driller's required record filed with the state documenting well location, depth, casing, screen, grout, water level, and formations encountered during construction.
- Well decommissioning
- Properly sealing an abandoned well, typically by filling and grouting the borehole, to eliminate a pathway for contaminants to reach groundwater.
- Setback requirement
- A rule-specified minimum horizontal separation between a well and a contamination source such as a septic system, lagoon, or fuel tank.
- Well registration
- A state record of a well's location, owner, use, and capacity; most non-domestic wells must be registered, and the record is separate from a water right.
- Registration number
- The identifier assigned to a registered well that stays with the site and must be referenced in reporting, permitting, and ownership transfers.
- Domestic well exemption
- A limited exception from registration for small wells serving a single household; the specific thresholds appear in Nebraska statute and rule.
- Registration versus water right
- Registering a well records its existence and use; it does not by itself authorize new irrigation acreage in fully or overappropriated areas.
- Use change notification
- An update filed when a registered well's use, capacity, or ownership changes, keeping state records accurate for water management decisions.
- Natural Resources District
- One of Nebraska's 23 locally governed districts that manage groundwater and may adopt rules, controls, and programs within their boundaries.
- Ground Water Management Area
- An area designated by an NRD where groundwater declines, conflicts, or quality problems justify additional controls such as moratoriums, metering, or allocations.
- Overappropriated basin
- A basin where existing water uses exceed or threaten to exceed supply; new uses typically require offsets, transfers, or a moratorium applies.
- Ground Water Quality Management Area
- An NRD designation triggered by contamination such as elevated nitrate, imposing requirements like fertilizer management and certified irrigator training.
- Pumping allocation
- An NRD-set limit on the volume of groundwater that may be pumped annually from a well or acreage inside a management area.
- Water use reporting
- The periodic submission of flowmeter readings and irrigated acreage required inside management areas, used to track allocations and compliance.
- Underground Injection Control
- The program under the Safe Drinking Water Act regulating fluid injection into wells; Nebraska's program is administered by the state with EPA oversight.
- Class V injection well
- A category covering shallow or miscellaneous injection wells, often authorized by rule but still subject to siting, construction, and inventory requirements.
- Class II injection well
- An injection well associated with oil and gas operations, including saltwater disposal and enhanced recovery wells, regulated under UIC requirements.
- USDW
- Underground source of drinking water: an aquifer or portion of one that supplies or could supply a public water system and is protected from contamination.
- Mechanical integrity test
- A test verifying that an injection well's casing, cement, and packer seal prevent fluid from escaping into unintended zones or drinking water aquifers.
- Injection permit
- The authorization required before constructing or operating a regulated injection well, setting pressure limits, monitoring, testing, and reporting conditions.
- Plugging and abandonment
- The approved procedure for sealing an injection well when it is no longer used, preventing cross-connection between aquifers and upward fluid migration.
- Wellhead Protection Area
- The delineated land surface and subsurface zone around a public well through which contaminants could move toward and reach the well.
- Source Water Assessment
- A state-prepared evaluation of a public water system's source susceptibility, based on contaminant source inventory and aquifer sensitivity.
- WHP program elements
- Four required components: delineating the protection area, inventorying contaminant sources, managing those sources, and planning a contingency water supply.
- Contaminant source inventory
- The systematic listing of potential pollution sources inside a protection area, such as septic systems, fuel tanks, and chemical storage sites.
- Contingency plan
- A public water system's prepared strategy for obtaining alternative water if its well becomes contaminated or otherwise unusable.
- Fixed radius delineation
- A simple wellhead protection method using a set radius around a well; other methods include calculated fixed radius and analytical or numerical modeling.
- Source water protection
- Voluntary and regulatory measures, such as land management, zoning, and proper well construction, that prevent contamination of drinking water sources.
