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.

In January 2011, the Reduction of Lead in Drinking Water Act was signed into law, which will reduce the allowable lead content of wetted surfaces in drinking water pipes, pipe fittings, and plumbing fixtures.

This act prohibits the sale of valves, fittings, and fixtures with a weighted lead content of more than 0.25% for any use with potable water.


The suppliers inventory of brass becomes obsolete on January 4, 2014. This means you will no longer be able to buy valves, fittings, or fixtures that contains lead which exceeds the 0.25% weighted average limit for wetted surfaces.
