Section Env-Dw 303.18 - Source Classification; Collection from Source(a) The applicant shall engage a qualified professional to classify the proposed source as spring water, artesian water, or well water, as follows: (1) A source shall be classified as spring water only if the water is from an underground formation from which water flows under a natural force to the surface of the earth through a natural orifice;(2) A source shall be classified as artesian water only if the water is from a well tapping a confined aquifer in which the water level stands at some height above the top of the aquifer and the water does not qualify as spring water; and(3) A source shall be classified as well water if it does not meet the criteria for classification as spring water or artesian water.(b) Artesian water may be collected with the assistance of external force to enhance natural underground pressure.(c) Spring water shall be collected either from the spring itself or through a borehole tapping the underground formation feeding the spring.(d) Spring water shall not be collected using external force unless the water is from the same underground stratum as the spring, as demonstrated by the following: (1) Observing and recording a measurable hydraulic connection, using a hydrogeologically-valid method, between the bore hole and the natural spring; and(2) Collecting and analyzing water quality samples to show that water derived from the borehole is of the same composition and quality and has all the same physical properties, before treatment, as the water that flows naturally to the surface of the earth.(e) Spring water shall not be collected using an external force if doing so prevents the natural flow of water to the surface of the earth through the spring's natural orifice.N.H.
