Details:	SUMMARY: Corrosion Control/Aeration Investigation DETAILS: The Lakeshoe Mobile Estates own & operate a GW system that provides water to approximately 75 people through 43 connections. The CR was originally contacted by the water system to provide assistance with Copper Level Exceedence & associated corrosion control. As a result of this ocntact, the system installed a caustic soda corrosion control system. The CR was subsequently contacted by Jay MacPherson of the DWS with the request that aeration be further considered. Coordinated for aeration testing at well. ACTION NEEDED: Perform aeration jar testing at the well site to further investigate viability of aeration in lieu of caustic addition.
