Water Resources Laboratory


Water Quality Analysis

Analysis of wastewater, drinking water, creek and ocean water are conducted or coordinated by the City’s laboratory. Tests performed follow protocols established by the Environmental Protection Agency as required by state and federal laws. The EPA established testing procedures with the intent to protect public and environmental health and safety.

Drinking Water Analysis

The lab routinely tests drinking water at the source and throughout the distribution system to ensure that water quality goals are met. The facility uses advanced equipment for the analysis of trace metals, inorganics and organic contaminants and other important parameters established by Environmental Protection Agency (EPA) standards. The City does not add fluoride to the drinking water.
