Cal Water Responds to EWG Report on Water

The Environmental Working Group (EWG) recently issued a report stating that the combination of contaminants in drinking water, even when each is under its individual maximum containment level (MCL), can increase the risk of cancer over a person’s lifetime. In contrast, California’s Office of Environmental Health Hazard Assessment (OEHHA) — which is composed of toxicologists, epidemiologists, physicians, biostatisticians, and research scientists — confirms that: “As long as drinking water complies with all MCLs, it is considered safe to drink.”

The EWG report pointed to smaller communities in particular being at greater risk; however, even in the smaller communities we serve, Cal Water maintains and upgrades water system infrastructure and treats, tests, and monitors the water supply to ensure the water we deliver meets all standards and is safe for our customers to use and drink.The report also acknowledges uncertainties with its methodology.

Protecting our customers’ health and safety is our highest priority, and we work to ensure our water complies with all water quality standards, or maximum contaminant levels, set by federal and state public health experts to protect customers’ health and safety.

We want our customers to know as much as possible about their water quality and encourage you to review the annual Water Quality Report for your water system, which includes every constituent detected in your water. (New reports with data for 2018 will be available in early June.)
