With the coming rainy season, some Sonoma County residents are fearful of the effects of runoff from the recent North Bay fires entering the nearby Russian River, a major source of water for Sonoma and Marin counties.

Scientists at the Lawrence Berkeley National Laboratory are studying the fire’s impact on the Russian River and the groundwater system, which serves about 600,000 residents in Sonoma and Marin counties, according to an article published by the lab last week.

The fires, which began Oct. 8, burned more than 100,000 acres and destroyed more than 5,700 structures. Many UC Berkeley students hail from the affected area and were subsequently uprooted from their communities.

The lab is also working with the United States Geological Survey, or USGS, and Sonoma County Water Agency, or SCWA, to monitor water quality in Sonoma County, according to an SCWA press release published last month.

There are six riverbank filtration systems located along and around Sonoma County’s Russian River, according to Michelle Newcomer, a postdoctoral fellow in the Climate and Ecosystem Sciences Division at the lab.

These riverbank systems, which pump river water 20 meters underground to natural aquifers, use sediments and environmental aerobic microbes to filter the water, according to Newcomer.
