 The Environmental Working Group (EWG) recently released an update to its National Tap Water Database that indicates more than 250 chemicals and 160 unregulated contaminants have been detected at “unsafe” levels in drinking water in communities nationwide. This information potentially misleads the public about the safety of its drinking water. 

While the EWG database reflects water quality data from nearly 50,000 utilities nationwide, it compares the data against public health goals for contaminants rather than legally regulated maximum contaminant levels. As a result, EWG’s report presents an inaccurate and misleading interpretation of the safety of drinking water in California and other states. EWG indicates on its website that it does not consider state and federal regulations stringent enough to protect public health. EWG also encourages consumers with “unsafe” drinking water to purchase water filters using the group’s Water Filter Guide.

Below are some facts to assure you that Rincon Water’s drinking water supplies are NOT in violation of water quality standards.

  • Delivering safe drinking water to residents and schools is job one for Rincon Water and all other California’s public water agencies.
  • The drinking water California’s public water agencies provide to homes, businesses and schools is safe and meets or exceeds all quality standards set by both the state and federal government. Local water quality staff continuously monitor water supply and conduct hundreds of thousands of laboratory tests each year from water taken from sample points throughout their service areas.
  • The U.S. Environmental Protection Agency and the State Water Resources Control Board Division of Drinking Water are responsible for establishing science-based standards that limit the amount of certain contaminants in water provided in public water systems. These limits are called maximum contaminant levels (MCLs). Water that meets state and federal standards IS safe.
  • An MCL is the maximum amount of a contaminant that can be present while still ensuring that the water is safe to drink. MCLs are designed to ensure that drinking water is safe to consume, while taking into account the feasibility of removing the contaminant so that water agencies can continue to deliver a consistently safe, reliable water supply at a reasonable cost.
  • An MCL is different from a public health goal (PHG). A PHG is the amount of a contaminant that poses zero risk to public health. In many cases, it is not possible to remove or reduce a contaminant to the level represented by the PHG because the technology may not yet exist or may be so costly that it would make tap water unaffordable.
  • Public water agencies are required to provide annual Consumer Confidence Reports (CCRs) to their customers that detail local water quality information. The reports are prepared in accordance with state and federal regulations and include information about the sources of drinking water supplies, what contaminants if any are in those supplies, and how those contaminants may affect public health. The reports also indicate how a district’s water supplies compare with state and federal standards. More information about CCRs can be found on the EPA’s website at
