Details:	SUMMARY: Request Invalidation of Routine Sample Taken 7-11-17 DETAILS: The operator called to inform me of a positive coliform result of a routine coliform sample. The sample was taken at the Spring House just after chlorination. There was a .37 Cl residual in the sample but the suction pump pulling water out of the Spring when the sample was pulled. Chlorine injection was just a few feet prior to this sample site. I told Kirk that this is not a good site for a "distribution" sample and asked that he remove this site from his coliform sampling plan. A more representative site would be after the upper reservoir just as it leaves to distribution. I AM REQUESTING INVALIDATION OF THIS SAMPLE DUE TO IMPROPER SAMPLE LOCATION. ACTION NEEDED: Another sample will be supplied for the monthly routine sample.Operator to take this site off of the sampling plan.Sent schematic of water flows to OHA - Michelle Byrd for reference.
