Public Water System Monitoring Plans

How to comply with requirements for monitoring plans for public water systems in Texas. Links to sample plan for a simple system.

All community and nontransient noncommunity water systems are required to develop a monitoring plan. Transient noncommunity systems must develop a monitoring plan if any treatment besides disinfection is present. Otherwise, for a transient noncommunity system with only disinfection, the bacteriological site plan counts as their monitoring plan.

Systems that treat surface water or groundwater under the direct influence of surface water (GUI) are required to send a copy of their monitoring plan to the TCEQ for review and approval. Systems serving at least 10,000 people had a deadline of January 1, 2001. Systems serving fewer than 10,000 people had a deadline of January 1, 2003.

Systems that use groundwater or purchased water are not required to send a copy of the monitoring plan to TCEQ, but must must keep the plan on file for review by the TCEQ inspector during routine comprehensive compliance investigations (sanitary survey), or must provide a copy of the plan to TCEQ upon request. These systems had a deadline of January 1, 2004, to complete the monitoring plan.

A newly revised detailed guidance is available to help you prepare your monitoring plan.
