Last period with anything received: 2026-07-31. Most often over: E. coli, thermotol, MF, MTEC (16), Flow, in conduit or thru treatment plant (4), Phosphorus, total [as P] (4).
Reports are due about 15 days after each monitoring period ends (read off this permit's own late-day counts in EPA's filings).
