Salt remediation of public water supplies

MassDOT Highway coordinates the investigation and remediation of public water supplies with regional offices of the Massachusetts Department of Environmental Protection (DEP).

Table of Contents

For a Non-Community Water System, MassDOT Highway will evaluate a salt contamination complaint from a water supplier that documents full compliance with 310 CMR 22 for at least one year. This compliance must be confirmed by the appropriate DEP regional office before MassDOT Highway can institute remedial action.

Before implementing any remedial action, MassDOT Highway will review the monthly data provided by the water supplier.

If the investigation determines that MassDOT Highway significantly contributed to the sodium and chloride concentrations in the public water supply, it may result in alternative mitigation strategies.
