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.
