Our worst fears were realized in the Feb 28th flood event. The largest gravel pit mine, Syar’s Basalt Pit, had a complete levee failure on a section that had failed in previous floods. The image at left shows the breach in center of picture, with river on the left and Syar Basalt Pit on right. Over 30 years of mining waste containing extremely high levels of toxic metals as well as Healdsburg’s treated wastewater discharges are now connected to our river – our drinking water supply.
Syar’s own testing in 2006 showed the mining waste contained mercury, iron and aluminum at 200-800% of safe levels and phosphorous at nearly 500 times higher than levels that can trigger toxic algae. Those pollutants are all conservative – meaning they are still present, do not degrade over time and pose a threat to the river’s health and our health.
When we filed lawsuits against the County in the 80’s and 90’s to stop the gravel mining, one of our biggest reasons was the fear of the gravel pits being captured by the river in floods. Sadly our predictions were correct, again. This occurred during the El Nino events in the late 90’s which resulted in a Clean Water Act lawsuit by Friends of the Russian River, RRK’s predecessor.
As of this date, three months after the flood, we’re still waiting for action plans to protect the river this summer from Healdsburg’s wastewater and the mining waste – both have very high levels of nutrients, mainly phosphorous, that could trigger toxic algae blooms. We’re also very concerned that in six months it’ll be raining again and if we do not take action we will see major erosion of downstream properties.
At this time, Permit Sonoma has convened two meetings with resource protection agencies and are developing a tentative plan. Permit Sonoma plans to hold a public meeting to collect comments on concerns regarding this issue and give you an opportunity to voice your opinion on how the County should respond to this major threat to the River’s health. We’ll keep you posted when the public meetings are scheduled, stay tuned!
