The specific evaluations included the following: 1.

The report details water quality regulations that the City is subject to as of 2023 including but not limited to the lead and copper rule, PFAS, new requirements for the Consumer Confidence Report (CCR), and the requirements for water quality of new groundwater sources.

Water Conservation Regulatory Review: Carollo conducted a review of existing and proposed water conservations regulations as well as including a review of the new California Water Loss regulations.
