Assistance Type: WATER QUALITY ALERT RESPONSE
Reasons: Coliform
 
Details: Spoke with Melvin regarding all repeats and triggered source samples coming back TC+ and EC+. He understands that he needs to collect 5 confirmation source samples within 24 hrs. Since E COLI is confirmed in the distribution a boil water notice was issued. Melvin had already posted notice on all doors. He will send in a copy of the boil water notice via mail since he doesn’t have email or text availability. It was explained to him that a Level 2 investigation will need to be scheduled. Awaiting results of confirmation source samples.

UPDATE 9/19: DEQ inspected the gravel filter for waste-water and gave it the okay. They don't believe it will lead to any contamination. Contamination could have occurred earlier since sampling was done before and during waste-water treatment repair. Waste-water treatment is <100 feet from wellhead. I recommended shocking and flushing system then doing two coliform samples in the distribution. Melvin, the operator, had learned from OWRD that the well was drilled in the 60's and he thinks the water line from well to pump house has never been replaced. He believes that it must be compromised somewhere and that is why the water system was subject to contamination during waste-water treatment repairs. He plans to replace the water line from wellhead to pump house and have all well components deep cleaned. Regardless if this was the cause of contamination, he wants to get this line replaced. After repairs are complete Melvin will take the two coliform samples in the distribution. I reminded him to take the samples at the homes in the distribution, not the treated sample tap in the pump house. He agreed to this plan.
