change of primary disinfection since Feb.2004
If you are an owner of a dialysis treatment unit and receive water
service from Sweetwater Authority or you receive dialysis treatments
from a provider within Sweetwater Authority's service area, our plans to
conduct water treatment tests may require you or your provider to take
special action.
The test period and protocol have been designed to determine whether
chlorine dioxide will be an effective disinfectant and whether it will
improve the taste and odor of water produced at the plant. We do not
anticipate any residual chlorine dioxide will leave the plant, but
expect a residual level of chlorite ion (ClO2-) will be formed as a
byproduct of the process. The concentration of chlorite ion is expected
to range from 0.2 to 0.8 mg/l.Chloramine residual levels in the
distribution system will not be affected.
If you have any medical concerns please contact your physician or your
renal dialysis service provider. If you would like additional
information or have any questions regarding Sweetwater Authority’s
plans, please contact Don Thomson, Water Quality Superintendent, at
(619) 409-6802 (email: dthomson@sweetwater.org).
