Uncovered and untreated finished water reservoir The South Street finished water reservoir is uncovered and the discharge is not treated. We were required to address this situation by April 1, 2009. 17 months We have hired an engineering firm to design a cover for the tank. We intend to have the tank covered by September 2010. Inadequately protected water may contain disease-causing organisms. These organisms can cause symptoms such as diarrhea, nausea, cramps, and associated headaches. Determine and Report Bin Classification After conducting our source water monitoring for Cryptosporidium, we were required to determine and report our Bin Classification by [date]. 1 We have since determined our bin classification and reported this to the DEQ. Inadequately treated water may contain disease-causing organisms. These organisms can cause symptoms such as diarrhea, nausea, cramps, and associated headaches. Manganese Manganese is a secondary contaminant that (starting in 2014) is required testing and has been put on all Massachusetts PWSs sampling schedules. Detections of this secondary contaminant must be reported in the CCR as in the tables below. If your system detects manganese greater than 50 ug/L (or ppb), you must report these concentrations in your CCR tables.
