20 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Contractor license
- The relevant professional authorization is distinct from a permit for a particular well activity or a separate water-use authorization.
- Water management district
- The regional Florida authority implementing delegated well programs, subject to the applicable state framework and any actual local delegation.
- Well completion record
- A factual account connecting the well location, formations, construction intervals, sealing, development, testing and final condition for accountable follow-up.
- Variance
- An authorized departure process where legally available, requiring actual review and approval rather than permission inferred from filing an application.
- Annular space
- The space between casing and borehole or between nested components, whose intended sealing or filter-pack function depends on the design.
- Tremie placement
- A controlled material-placement method using a pipe to reach the intended depth, helping avoid unfilled intervals and bridging when properly specified.
- Filter pack
- A deliberately selected permeable material around the intake, designed with the screen and formation rather than serving as a sanitary seal.
- Centralizer
- A device helping maintain the intended casing position and annular geometry for installation and sealing, without itself proving complete grout placement.
- Drawdown
- The change between static and pumping water levels under stated conditions, measured from a consistent datum rather than the total well depth.
- Specific capacity
- The discharge divided by observed drawdown for the specified test conditions, not an unconditional prediction of permanent sustainable withdrawal.
- Transmissivity
- A measure relating transmission through the saturated aquifer thickness, represented by hydraulic conductivity times thickness in the appropriate simplified model.
- Confining unit
- A comparatively low-permeability layer restricting flow between formations, which should not automatically be treated as an absolutely impermeable boundary.
- Flowing artesian condition
- A condition in which pressure head raises groundwater above the relevant ground-surface elevation so uncontrolled flow can occur without pumping.
- Duty point
- The flow and head combination at which the selected pump and actual system operate, evaluated using the relevant curve and conditions.
- Total dynamic head
- The combined relevant lift, delivery-pressure head and losses the pump must overcome under the specified operating conditions and reference datum.
- Tank drawdown
- The usable volume delivered between the specified pressure control points, which is different from the pressure tank’s nominal total volume.
- Short cycling
- Rapid repeated pump starts and stops that require diagnosis of tank, controls, demand, leakage and other system conditions rather than an assumed single cause.
- Hazardous-energy isolation
- Control and verification of relevant electrical, hydraulic, pneumatic and other energy before work, rather than relying only on an engine stop.
- Turbidity
- An optical measure associated with suspended particles and scattering, not a complete determination of chemical or microbiological drinking-water safety.
- Confined-space assessment
- Evaluation of access and atmospheric or other hazards with applicable controls before entry, not clearance based on odor or casual observation.
