Details: SUMMARY: Inquiry about TOC sampling frequency DETAILS: Gary phoned because the lab informed him that they should be sampling TOC monthly but he thought it was quarterly. On Data Online, it did say monthly. But after reviewing their extended set of quarterly DBP results, it became apparent that the DBP schedule could be reduced to annual at this point, with a dual set of DBP samples due each November (month of highest historical results). The TOC interval would then be quarterly. I informed Gary by phone. He will still collect a quarterly DBP sample in November 2015, as that would be the month for annual sampling as well. ACTION NEEDED: Submit a schedule change form to DMCE so that starting in January 2016, their DBP schedule will be annual (during month of November) at the same Stage 2 DBP sampling location, and the raw water TOC schedule will be quarterly.
