Water Security

Important Workshop




  • California DHS has had an action level for chlorate since 1990 when they first established a policy on use of chlorine dioxide. Their concern about chlorate was reiterated in a 1997 policy guidance on hypochlorination (PDF file) and was addressed in a 1998 policy guidance on chlorine dioxide (PDF file) (see closing paragraph)
  • The updated evaluation of chlorate health risk by the Cal-EPA's Office of Health Hazard Assessment (transmitted to CDHS in a January 7, 2002 memorandum (PDF file, 13 pages)) was requested by CHDS because of concerns about findings of chlorate in groundwater associated with hazardous waste clean-up activities in Southern California.


  • Scientists discuss Utah's uranium mine tailing (Salt Lake Tribune, January 22)
    Commentary: A National Academy of Sciences panel heard appeals for action from downstream water users, Colorado River recreationists, local citizens and a noted author-environmental activist for action on a huge pile of uranium mine tailings essentially abandoned by the mining company. But, panel members suggest the decisions are not scientific, but political.

Alternative Drinking Water Mandate

  • 1996 SDWA Amendment artifact still haunts users of raw "ditch" water
    (Auburn Journal, January 18)
    Commentary: An "out of sight, out of mind" change in the SDWA in 1996 is still in the throes of implementation in California's Sierra-Nevada foothills, along the border areas of the U.S. and Mexico, and in some other locales where "raw water" conveyances deliver raw water mostly for irrigation or on the way to a community system for treatment. Previously exempt from the SDWA because they were not "pipes", these facilities led to an arrangement of self-certification by individual homeowners to demonstrate that they have some alternative safe drinking water provision.
