“Contamination levels of Richardson Bay waters near the spill site are above the state safety standard, according to preliminary test results released Saturday. County officials said that the contamination did not extend beyond Richardson Bay and that there was no indication San Francisco beaches were affected.
The sample at the Bay Front Office Park, taken upstream of the spill site, had the highest level of contamination, which could be caused by recent rainfalls pushing the sewage-contaminated water upstream, officials said. The Shelter Bay Mill Valley site, located downstream, was slightly elevated. Schoonmaker Beach and Dunphy Park in the Sausalito area showed low levels of bacteria but met the state standard for water recreation. ”
