BACKGROUND INFORMATION: The Public Health Goals Report is prepared by Public Works staff comparing Lodi's drinking water with California Environmental Protection Agency's (Cal EPA) public health goals (PHGs) and with the United States Environmental Protection Agency (USEPA) maximum contaminant level goals (MCLGs). PHGs and MCLGs are not enforceable standards and no action to meet them is required. California Code of Regulations, Title 22, Section 116470, mandates a Public Health Goals Report be prepared every three years. The report is intended to provide water quality information to the public in addition to the Annual Water Quality Report, which the City mails to each customer by July 151 of each year. The draft report has been made available on the City's website at www.lo_di.gov/528. The law requires a public hearing be held (which can be part of a regularly scheduled public meeting) for the purpose of accepting and responding to public comment on the draft report. The City's water system complies with all of the health -based drinking water standards and maximum contaminant levels as required by the State Water Resources Control Board, Division of Drinking Water and the US EPA. No additional actions are required or recommended. FISCAL IMPACT: Not applicable. FUNDING AVAILABLE: Not applicable. C �ju _(�) C arles E.
