Details:	SUMMARY: Wellfield Determination DETAILS: Request was made to review Well #3 for an initial chem monitoring reduction. Wellfield Determination was conducted and results indicated that all 3 Rivergrove Wells draw water from the same aquifer and that the landuse practices near each well are similar. Well #2 was identified as the most susceptible well therefore, long-term representative monitoring should occur on the Entry Point that Well #2 is connected to. Annual nitrate samples should continue to be collected at all other Entry Points. See SWA file for further details. ACTION NEEDED: Monitoring schedules altered to reflect initial monitoring reduction and wellfield designation.
