Alternative Source Well (ASW)
-a well that
					 produces water from a water-bearing stratum other than a ground water aquifer,
					 underground source of drinking water (USDWs), or at a depth or location within
					 a ground water aquifer containing water greater than 10,000 mg/l TDS.
a.
ASW-Type A
-an alternative source well
					 with a well screen installed in stratum that is not hydraulically connected and
					 not in communication with a ground water aquifer or USDW.
b.
ASW-Type B
-an alternative source well
					 with a well screen installed in stratum that is below the base of the USDW but
					 is hydraulically connected and in communication with a ground water aquifer or
					 USDW, or at a depth or location within a ground water aquifer containing water
					 greater than 10,000 mg/l TDS.
Aquifer
-for purposes of this Chapter, a
					 ground water bearing stratum of permeable rock, sand, or gravel.
Department

Mg/l
-milligrams per liter.
TDS
-total dissolved solids.
Rework or Reworking
-rehabilitation or
					 modification of an alternative source well to increase its efficiency, restore

					 supply a public water system, currently supplies drinking water for human
					 consumption or contains fewer than 10,000 mg/l total dissolved solids.
Water Well
-any well drilled or constructed
					 for the principal purpose of producing ground water.
Water Well Contractor
-a licensed
					 contractor who drills all ground water wells, test and pilot holes, monitoring
					 well, observation wells, heat pump wells and holes, and geotechnical boreholes,
