Chromium (total)

California Water Service Company-Lancaster

NOTE: California Water Service Company-Lancaster purchases water from Antelope Valley - East Kern Water Agency which is required to test for chromium (total). Sample information shown below was taken by Antelope Valley - East Kern Water Agency.

Chromium is a naturally occurring metal, but industrial uses can elevate its levels in water. One form, hexavalent chromium, causes cancer. Total chromium is not a good indicator of the amount of hexavalent chromium in drinking water.

EPA Maximum Contaminant
Level (MCL): 100 ppb

The legal limit for total chromium, established in 1991, was based on a 1958 toxicity study in laboratory animals, and applies to both the less-toxic trivalent chromium and the more-toxic hexavalent chromium forms of this compound. This limit does not protect against the risk of cancer from ingestion of hexavalent chromium.
