A quick addendum to last week’s story about Stockton’s impending conversion to chloramines as a disinfectant in the drinking water.
First, you can group the state Department of Public Health with the EPA in saying chloramines are safe. A spokesman for Public Health belatedly sent me the following statement: “CDPH has not provided statewide approval for the method of switching from chlorine to chloramines. However, the use of chloramines is safe and can be approved on a case by case basis through the CDPH permitting process. For example, there are a few large metropolitan areas in the state (i.e., Los Angeles, San Diego, San Francisco) that currently utilize chloramination treatment. The City of Stockton has submitted preliminary plans as part of their request for approval for the change, but have not yet submitted the final plans.”
Also, it turns out Stockton is not the first local community to make the change. Tracy has used chloramines in its drinking water since 1993, a public works spokesman told me.
People concerned about purported health risks seem to feel I downplayed said risks, and some of them have posted interesting comments at the bottom of last week’s article. At least three of the comments are from people who appear to live outside of this region.
