Subject: Parkton WWTP, WET failure for April
Parkton's WET resulted in a "fail". The failure was related to reproduction only, not lethality. Terry Wages said that the
turbidy had increased during the week of the WET sampling, but no exceedence for TSS, related to increased flow (rain,
I&I). The effluent appearance has now improved. The chlorine of the WET samples were <0.1 mg/L. Parkton has flow
proportional chlorine dosing, but dechior with tablets. The multiple dilution WET is scheduled for the first week in
May.
