City receives and files 2025 drinking-water public-health goals report; system meets enforceable standards
Summary
Public Works presented the 2025 drinking-water public-health goals report showing Manhattan Beach water met all state and federal maximum contaminant levels; some advisory public-health goals for imported water showed trace exceedances but were below enforceable limits.
City water officials presented the city's 2025 public health goals hearing, summarizing drinking-water sampling from 2022'24 and comparing the results to state and federal benchmarks.
Sandy Neat, the city's water compliance supervisor, told the council Manhattan Beach draws water from both local wells (treated for manganese) and Metropolitan Water District supplies. "The drinking water delivered to our Manhattan Beach customers met all state and federal standards," Neat said. She added that some constituents in the imported Metropolitan Water District supply exceeded advisory public health goals (PHGs/MCLGs), notably trace arsenic and gross alpha/beta measurements, but remained well below enforceable maximum contamination levels (MCLs).
Neat emphasized that public health goals and MCLGs are advisory and conservative benchmarks; further reduction of trace constituents would require costly advanced treatment with minimal added public-health benefit. The council voted unanimously to receive and file the report.
Public commenters on Zoom asked about the city's options when imported water shows advisory exceedances; staff replied that treatment responsibility lies with Metropolitan Water District and that the city's water currently complies with enforceable limits.
The report will be filed with the state as required and no immediate additional treatment action was recommended by staff.
