Stockton’s conversion to a new chemical to treat city drinking water has been delayed until November due to permitting issues, officials said this week.
The conversion to chloramine was originally supposed to happen in early June.
Some residents have expressed concern about putting a new chemical in the water, despite the fact that chloramine is already used in major cities across the country, and an Environmental Protection Agency toxicologist has said health impacts are “pretty rare.”
Still, it’s important that residents are aware when the conversion takes place, because water with chloramine requires special treatment before it can be used for aquariums or koi ponds, or for kidney dialysis patients.
Once the permitting issues are resolved, chloramine will replace traditional chlorine, a disinfectant used to kill any bacteria that might seep into distribution pipes. Only city of Stockton ratepayers mostly north of the Calaveras River are affected by the change.
