LAKE COUNTY, Calif. – Well testing, soil decontamination and removal, and water tank installations are underway as part of the ongoing work to respond to a massive sewage spill that occurred in Clearlake earlier this month.

It’s been two weeks since a 16-inch force main near the northern end of Robin Lane in Clearlake – operated by the Lake County Sanitation District – ruptured, sending nearly three million gallons of raw sewage across roads and private properties, contaminating dozens of wells and forcing some residents of the spill area to temporarily relocate.

The county is set to hold its third town hall meeting on the spill and its remediation efforts at 6 p.m. Wednesday, Jan. 28, at Clearlake City Hall, 14050 Olympic Drive.

Public Health Officer Dr. Bob Bernstein’s guidance encouraging residents who rely on their wells for drinking water to temporarily relocate until the wells are deemed safe remains in place since last week.

The county reported on Saturday evening that contractors with Lake County Environmental Health, which has been tasked with well testing and long-term monitoring, “will continue health and safety field operations” on Sunday.

“Contractors continue to work in the field sanitizing private wells. This includes wells that had not yet been sanitized as well as wells that were previously sanitized but are still showing some level of contamination,” the county reported.

Officials also said that, “Follow-up actions are being taken to ensure each well receives the appropriate treatment and testing before normal use is resumed.”

Environmental Health is planning to begin its second round of water sampling as early as Monday to confirm results and track ongoing improvements in water quality, the county reported.

Meanwhile, Lake County Special Districts, which oversees the Lake County Sanitation District, is continuing soil cleanup efforts, which are expected to go on for several more days. 

Contaminated soil will be removed to a lined pond at a Special Districts facility, and agricultural lime will be applied to exposed soil areas as conditions allow to support treatment and stabilization efforts.

Road work on Robin Lane will begin on Monday. Lake County Public Works crews will grade the
roadway, transport removed soil, and apply approximately 3 inches of base rock to improve road conditions and support continued access for residents and response vehicles, the county said.

The county said Special Districts staff will be collecting 15 private well water samples on Sunday as part of continued monitoring efforts. 

Water delivery for livestock will continue through the weekend and into the coming week to ensure animals have access to safe water, according to the county update.

Social Services administers the Home Safe program, which is supporting water tank installations for residents who need access to alternative water supplies. 

Additional tank installations are scheduled to begin Sunday or Monday. Tank placement is being prioritized based on well testing results, the county said.
