Details:	SUMMARY: Coliform sampling error DETAILS: Spoke with Brenda of Delta Lab who said the original sample taken 9/21/07 was taken before UV treatment. Coliform samples are required to be taken after any treatment. They have already taken the four required repeat samples, all came back absent. She was requesting we invalidate the original sample and not be required to take the five routine samples in October. I forwarded her request to our data management team for their determination. ACTION NEEDED: await DMCA determination to invalidate original sample 9/21/07.
