Contaminated water found in Rohnert Park subdivision
Blaise Turek looked forward to taking a hot shower after he and his wife returned home from vacation in mid-December. But when he turned the faucet on, brownish water with a putrid stench flowed out.
“The smell was off the charts,” he said.
Almost a month later, the Tureks and more than a dozen other property owners in the Canon Manor West neighborhood just east of Rohnert Park are still dealing with fallout from contamination in their water wells.
County health officials this week revealed that 17 of 31 residential wells tested in the development south of Sonoma State University are ridden with potentially harmful bacteria, including E. coli in seven of the contaminated water sources. Besides ordering residents to discontinue using the wells, officials will be sending letters to every property owner in the 257-acre development warning them of the problem and urging precautions.
“I think it’s an urgency,” said Karen Holbrook, the county’s deputy health officer. “People should be aware that they are potentially drinking water that’s not safe.”
More than a public health concern, the well contamination in Canon Manor West highlights longstanding disputes in several Sonoma County neighborhoods over water rights and responsibility for ensuring that the water is safe.
Holbrook on Wednesday said the consensus among county officials and those from the city of Rohnert Park — which maintains a sewer line in Canon Manor West — is that failing septic systems and surface water contamination are to blame for the well problems.
Several residents, however, accuse the county of using the current crisis as an excuse to enforce an ordinance requiring Canon Manor West residents to hook up to public water and sewer lines, abandon and destroy septic systems and to discontinue well use for domestic purposes.
Melanie Hildebrand, who lives across the street from the Tureks on Lynn Drive, pinned the blame for contamination of the private well she uses for irrigation on poor maintenance of Rohnert Park’s sewer line. She said the county’s effort to get people in the development hooked up to public sewer and water is “unrelated to the issue.”
Problems date to ’70s
The county’s ordinance, adopted in 2006, sought to resolve a decades-old battle over private well and septic system use in Canon Manor West, which is southwest of the intersection of East Cotati Avenue and Petaluma Hill Road.
As far back as 1976, excessive and elevated levels of nitrates began showing up in a few private wells. Health inspectors said the contamination likely emanated from fecal material from former chicken farms in the area.
A 2010 amendment to the ordinance described continued use of private wells and septic systems in Canon Manor West as “an immediate danger to public health.” But dozens of property owners appear to be flouting the law.
The Tureks are among those who held out. Blaise Turek said that’s because the couple’s well and septic system were sufficient for their use, and because no one forced the issue.
“It was perfect water and nobody ever questioned it,” he said. “Nobody.”
That’s changed with the bacterial contamination. Besides putting an unwanted spotlight on residents who continue to use private wells and septic systems, it has forced some into taking quick action.
