CALIFORNIA STATE DEPARTMENT OF HEALTH DRINKING WATER TEST RESULTS
The California State Department of Health, Drinking Water Division, Sacramento, California, has all of the water test data from every public drinking water source in the State of California, dating back to 1980s.
These tests are required by the EPA and the State of California, due to possible health effects, when various metals, herbicides, pesticides and other toxic contaminants are found in drinking water sources. The California EPA has complete listings of these chemicals, associated health effects, and drinking water standards for these water contaminants. The results of all drinking water tests are available free of charge online from the California State Department of Health.
1) A review of all water tests conducted in the State of California between 1984 and 2008, for every water test result over -0-, has been completed in the last year to find any unusual water contaminant readings which are over State of California standards and that could have negative consequences for human health.
2) The review demonstrated unusual spiking patterns, across California, for some toxic drinking water contaminants that that raise concerns about air borne and other pollution sources. This review raises serious questions about why the public has not been informed of these unusual spiking patterns by the California State Department of Health. This list includes, but is not limited to, the following contaminants:
(The California Air Resources Board tested for most of these airborne contaminants between 1989 and 2002, and found significant increases or spiking in these many of these pollutants.)
A review of water temperatures, specific conductance, and pH should also be considered in any examination of these test results. (Please note that many contaminants were not reviewed due to the large database - all drinking water contaminants will be under review in the future.)
3) Many of the contaminants listed above that were found in drinking water tests spiked in the same years in different parts of the State. There may be an airborne link to these water contaminants which will need to be studied in the future.
(In an article in the Sunday, February 23, 2003, edition of the Sacramento Bee, written by Chris Bowman, it was noted that Tungsten, not normally tested for in public drinking water supplies, was found in Elk Grove, Sacramento, in drinking water supplies, and in tests conducted on trees rings in that area as well. Similar results were found in Fallon, Nevada and Sierra Vista, Arizona. Tree ring tests are showing increases in Tungsten.)
All drinking water tests are public record and are available upon request from any state in the United States and local water purveyors. Remember that your local water supplies may or may not test for these contaminants on a regular basis. The data one should request is not summary data but actual test results.
Water tests do not take into account the synergistic effects of multiple contaminants. In addition, water treatment facilities vary from county to county as well as state to state…thus, your water treatment facility may not be able to remove all contaminants in your drinking water.
(Note: If contaminants are found in your drinking water supplies then they are also showing up in rivers, ponds, streams, shallow wells, and the ocean. All of these areas, along with most irrigation water, cannot be treated for contamination problems. This means that these chemicals will show up in our soils, food supplies and also have negative impacts on wildlife and marine life.)
In California, information is available in a timely manner under the California Public Records Act. Under this act no agency may overcharge for copying costs or charge California residents money for time spent on researching this data (no labor charges are allowed under this law), to residents requesting information.
