Summary

Supervisor Yee asked the Board to hold a hearing on the San Francisco Public Utilities Commission's Groundwater Supply Project, citing community concerns about testing, nitrate levels and changes in taste and odor for blended drinking water.

Supervisor Yee asked the Board on April 18 to hold a hearing examining the San Francisco Public Utilities Commission's Groundwater Supply Project, which would blend treated water with groundwater and place up to 15 percent groundwater in the city's water blend to diversify supply.

Yee said the project has been the subject of a decade of testing by SFPUC staff and that the agency concluded blended water would meet regulatory safety and quality standards set by the California State Water Resources Control Board and the U.S. Environmental Protection Agency. He said the initial rollout will affect several districts and that some community members have expressed concerns about nitrate levels and taste and odor changes that have been noted in past blending adjustments.

Yee asked for a hearing so SFPUC staff can address questions and concerns from the public and the Board. The item as presented on April 18 was an introductory request for a hearing; the transcript does not show a final Board vote to schedule a specific hearing date on April 18.
