About E.coli Monitoring Requirements in Domestic Wastewater Permits issued under the Texas Pollutants Discharge Elimination System (TPDES). Shows how the TCEQ arrives at the monitoring frequency for bacteria.

A violations are sent straight to enforcement, "B"s must be documented twice before enforcement action is taken, and "C"s may or may not be sent to enforcement after being documented 3 times in a five year period. This document can be revised at any time.

In Domestic Wastewater Permits issued under the Texas Pollutants Discharge Elimination System (TPDES)

Rob Donofrio, Director of Microbiology, NSF International; Trent Martin, Harris County, Watershed Protection Group; Paul Jackson, Program Development Manager, NSF International, March 11, 2009. Almost every stream in Harris County is listed by the EPA as impaired due to high E. coli levels. Data shows that adding up bacteria loads from all the sources of flow into the stream did not come close to approximating the amount of bacteria that we see in the stream.
