(q) "Final report" means the report submitted to the department after the pumping test and water quality sampling programs are conducted at the proposed well site.
(r) "Flow net" means a map showing lines of equal hydraulic head with lines showing the direction of groundwater flow such that the amount of groundwater flow through all sections of the net is equal.

(t) "Hydrogeology" means the study of the occurrence, movement, and chemical nature of surface water and groundwater in relation to its geologic environment.
(u) "Known contamination source" means a land use from which contaminants are known to emanate and degrade groundwater quality.
(v) "Large overburden production well" means a production well that produces a permitted production volume of equal to or greater than 57,600 gallons which is exposed to and draws water from any type of unconsolidated material, including but not limited to, sand and gravel deposits. The term includes dug wells, tubular wells, well points, and naturally developed gravel wells.
(w) "Large bedrock production well" means a production well that produces a permitted production volume equal to or greater than 57,600 gallons and which is exposed to and draws water from any type of consolidated material.
(x) "Monitoring well" means a well used to observe or sample groundwater.
(y) "New well" means any well without current design approval in accordance with Env-Ws 372 or Env-Ws 373 or any well that has been inactive and has not been regularly sampled under the system's chemical monitoring program or any well that is deepened or otherwise improved to increase its approved yield.
(z) "Permitted production volume" means the maximum volume of groundwater allowed by the department to be withdrawn or pumped from a public water supply production well in a 24-hour period.
(aa) "Porous media assumption" means groundwater flow that conforms to Darcy's Law, mainly flow through porous media which is laminar and of low velocity.
(ab) "Potentiometric surface" means the surface where groundwater pressure is equal to atmospheric pressure.
(ac) "Potential contamination source" means human activities or operations that pose a risk that regulated contaminants might be introduced into the environment in such quantities as to degrade the natural groundwater quality. The term includes those land uses listed in RSA 485-C:7,II.
(ad) "Preliminary report" means the report submitted to the department prior to conducting the pumping test and water quality programs at the proposed well site.
(ae) "Production well" means a well designed and constructed to withdraw groundwater for a community water supply system.
(af) "Pumping test production rate" means the constant pumping rate that is maintained throughout the pumping test which is used to establish the permitted production volume.
(ag) "Regulated contaminant" means "regulated contaminant" as defined in RSA 485-C:2, XIII namely "any physical, chemical, biological, radiological substance or other matter, other than naturally occurring substances at naturally occurring levels, in water which adversely affects human health or the environment."
(ah) "Supplier of water" means a "supplier of water" as defined under RSA 485:1-a, XVI namely "any person who controls, owns or generally manages a public water system."
(ai) "Surface water" means "surface waters of the state" as defined in RSA 485-A:2, XIV, namely "streams, lakes, ponds and tidal waters within the jurisdiction of the state, including all streams, lakes, or ponds bordering on the state, marshes, water courses and other bodies of water, natural or artificial."
(aj) "Test well" means a well used during a pumping test from which groundwater is withdrawn or pumped which may or may not become the production well.
(ak) "Well" means any conveyance used to capture or withdraw water from the ground.
(al) "Wellhead protection area" means "wellhead protection area" as defined in RSA 485-C:28, XVIII namely "the surface and subsurface area surrounding a water well or wellfield, supplying a public water system, through which contaminants are reasonably likely to move toward and reach such water well or wellfield". The term includes the contributing area for production wells which supply community water systems.
