Ground Water Rule Contact Time (CT) Calculator
- The Groundwater Rule (GWR) Contact Time (CT) Calculator (3M ZIP file) is an Excel spreadsheet tool designed to help groundwater systems determine minimum virus log inactivation based on various operating parameters (e.g., flow rate, type of disinfectant, temperature, etc.). The tool may assist operators in determining whether a change in treatment precesses may benefit or adversely impact the system's ability to meet its disinfection goals.
  Please ensure that macros are enabled when you use the CT Calculator
Groundwater Rule Placards
The Groundwater Rule (GWR) Monitoring Requirements Placards are an Adobe pdf tool to help systems understand monitoring and communication requirements under the GWR. The tool targets system types (i.e. CWS, NCWS, wholesale, consecutive systems) and the specific information on which GWR requirements must be met. Using the placards, it is the goal of EPA that operators of specific system types be able to udnerstand which GWR requirements must be met in the event that a total coliform-positive or fecal coliform-positive sample is identified.
