(j) "Hydrology" means the science of the occurrence, circulation, distribution and properties of the waters of the earth and reaction with the environment.
(k) "Large withdrawal" means any seasonal or year-long withdrawal from a wellhead installed after July 1998, not associated with a temporary, short term use such as contaminated site management or construction de-watering, where the maximum 24-hour withdrawal is 57,600 gallons or more.
(l) "Permitted withdrawal" means a large withdrawal permitted under these rules.
(m) "Potentiometric surface" means the surface where groundwater pressure is equal to atmospheric pressure.
(n) "Public water system" means "public water system" as defined by RSA 485: 1-a, XV, namely "a system for the provision to the public of piped water for human consumption, if such systems have at least fifteen service connections or regularly serves an average of at least twenty-five individuals daily at least 60 days of the year."

(q) "Replacement well" means a new source installed to replace an existing source that operates and impacts water resources in the same manner as the well that is being replaced.
(r) "Short term use" means the one time occurrence of a withdrawal at a specific geographical location over a period of one year or less, except for contaminated site remediation, where the duration of the withdrawal extends for the time necessary to complete the objectives of the remediation.
