What is chromium?

Chromium is an odorless, tasteless metallic element that occurs in rocks, animals, plants, and soils. It occurs naturally in most water supplies. Chromium can be present as either chromium 3 (trivalent) or chromium 6 (hexavalent). Chromium 3 is a nutrient found in many vegetables, fruits, meats, grains, and yeast. Chromium 6, which is toxic, occurs naturally in the environment due to erosion of the natural manufacturing processes such as electroplating, pulp processing, and wood treatment and can be found in products such as treated wood, tanned leather, and stainless steel. 

Is chromium in Bremerton's water supply?

Bremerton's water system is mostly surface water which has negligible levels of chromium. Groundwater sources in Bremerton contain low levels of chromium and similar results are found in other Kitsap area water systems and throughout the United States. Bremerton's results are well below the established limits set by the Environmental Protection Agency (EPA).

Bremerton's water sources are protected and far from industrial locations. Chromium present in Bremerton's water is likely naturally-occurring. Regular testing of water sources in Bremerton for chromium and other chemicals verifies the excellent quality of the water.
