Considering chloramine

Is San Francisco's water causing weird rashes in some people? Stalled bill means we may never know
BY JON BECKHARDT

For three years, dozens of Bay Area residents have alleged the water disinfectant used in San Francisco and other cities causes a variety of symptoms ranging from asthma to fainting to rashes. The San Francisco Department of Public Health has spent more than $100,000 to study the chemical, chloramine, but it has not done a full scientific study that might prove or disprove a connection between the chemical and the reported symptoms.

Responding to the lack of scientific studies on the dermatological and respiratory effects of the chloramine, Assemblymember Ira Ruskin (D–<\d>Redwood City) introduced legislation to further study the chemical, but the measure was held up in the Appropriations Committee as the June 8 deadline for advancing it passed, frustrating those who hoped to finally get some answers.

Chloramine replaced chlorine in San Francisco's water system in February 2004 after the Environmental Protection Agency tightened regulations against trihalomethanes and haloacetic acids, chlorine by-products that may be carcinogenic.
