Revised Total Coliform Rule Sampling Resources

Revised Total Coliform Rule (RTCR) Placards:

The RTCR Placards are a collection of six (6) e-fillable placards on the RTCR requirements.

  • Designed for primacy agencies to give to small PWSs that serve 1,000 or fewer persons.
  • For non-seasonal PWSs, there are three (3) placards for collecting routine samples per Month, Quarter, or One-time a Year.
  • For seasonal PWSs, there are two (2) placards for collecting routine samples per Month or Quarter.
  • For all PWS, there is one (1) placard on Level 1 or Level 2 Assessment requirements.
