Assistance Type: WATER QUALITY ALERT RESPONSE
Reasons: Coliform
GWR
 
Details: SUMMARY: Total Coliform Positive in Distribution System DETAILS: Ken called for clarification regarding repeat sampling requirements. I told Ken that 3 repeats plus GWR triggered sampling was required. Specifically, one sample upstream, one sample downstream, and one sample at original positive location, and in addition, the GWR requires a triggered source water sample. The City of Sheridan has been approved to use a common header (CH-A) for the spring sources (the only sources operating at the time of the original sampling). ACTION NEEDED: Depending on results more action may or may not be needed.
