DMON |
Only 1 of 2 analytical events for THM (chlorodibromomethane, chloroform, and dichlorobromomethane) was conducted in November, 2019. Attachment E, section IX.D.1 of the Permit requires 2/month during November 1 through March 31.
EWWTP was under the false impression that the attachment E, Section D requirement of twice per month during Nov.-March only applied during the collection of the ROWD data beginning in 2020, similar to the frequency of analysis in our last permit. |
We have corrected our sampling schedule and will be collecting THMs twice per month beginning December, 2019 |
