| Details: | SUMMARY: Positive coliform sample 7/18/11 DETAILS: Mr. Shires called asking for protocol to chlorine shock a well following a sample showing the presence of coliforms. He had calculated the well volume@ 1584 gallons and using state website I told him 1 1/2 gal plus 1 cup for 6 hours contact time would suffice. He understood need to run water to each faucet until chlorine was detected and after 6 hours to flush system. He explained that the UV light had recently been replaced and after the bad sample result he found the 5 micron filter past due for replacement and was in process of changing it. Reviewed by phone and followed up with email taking a triggered source sample, 4 repeat samples from distribution and next month 5 temporary routines from distribution and a potential need for public notice based on follow up results. Encourage him to contact ODA for further technical assistance. Emailed the state website of steps to chlorine shock system along with ODA number in Salem. ACTION NEEDED: 4 repeat samples. One triggered source sample and next month 5 temporary routine samples. | ||
