Why Are TheseUpdates Necessary?
Guidelines clarify interpretations of the Massachusetts Drinking Water Regulations (310 CMR 22.00)
Establish protocols for addressing site-specific problems encountered in the field
Set the regulatory framework necessary to maintain or improve public health and welfare

9.10.2 Adoption of Local ControlsSuccessful promotion of a cross-connection
control and backflow prevention program will be dependent upon legal authority to conduct such a program
MassDEP recommends that a municipality adopt an ordinance, by-law, or have a policy statement on cross-connections that will establish a program for inspection and strategies for the elimination of cross connections within the community
