A short-term water emergency was declared Wednesday on the Russian River because of a black plume of water that originated from a ranch on the Laguna de Santa Rosa, water officials said.

Runoff from the recent rains is being blamed for causing the discoloration in the river, which prompted the Sonoma County Water Agency and other water districts to stop pumping operations, affecting several thousand residents.

"Our facilities at Mirabel, the three collector wells, are shut down, and we are not using them until they can determine why the water is discolored," said Pam Jeane, deputy operations director of the Sonoma County Water Agency.

State Water Regional Quality Control officials said Wednesday they believe the discoloration may have been caused by decaying material that washed into the river, but that it does not appear to pose a hazard.

"We have water samples we are shipping off, looking for pesticides, because ludwigia was sprayed in the laguna," said Dave Evans, a senior engineer with the state Regional Water Quality Control Board.

The state Department of Public Health called for the water agencies to turn off their pumps Tuesday night as a precautionary measure and rescinded the order at 4 p.m. Wednesday.

The discoloration was seen Tuesday and Wednesday in the laguna, in Mark West Creek near Forestville and in the Russian River at Steelhead Beach, Vacation Beach and the Hacienda Bridge.

Using the sheriff's helicopter, biologists from the Sonoma County Water Agency followed the plume back to the 240-acre ranch owned by Val Aggio.

A portion of the ranch, which sits adjacent to the laguna between Occidental and Guerneville Roads, had recently been tilled, and the ludwigia that was on the land had been plowed under, Evans said.

The land was tilled before the recent rains, which he believes washed material from the top of the land into the laguna.

Evans and officials for the state Department of Fish and Game both said that there is nothing to indicate that anything illegal has occurred, but they will make a final determination after they get the water samples back.

"We are not making those decisions until we find out what the impacts were," Evans said. "We know it was visual. We have nothing that looks like intent or negligence was involved."

Aggio was not available for comment.

The Sonoma County Water Agency continued pumping from its Wohler Bridge intakes, which provide enough water -- 30 million gallons a day -- for its 600,000 customers, Jeane said.

"We grabbed a couple of water samples," Jeane said. "The water is colored, there is not a lot of sediment in it, there are the little bugs that normally live in the water and they are still swimming around in it."

Jeane said that they won't turn the pumps back on until there is no color in the river at all.

Sweet Water Springs, which serves 4,400 customers and 10,000 residents in the Guerneville area, called for emergency conservation measures Tuesday night, but rescinded that order Wednesday afternoon, said General Manager Chuck Howell.

Howell said they initially turned off their pumps in the river and were relying on water stored in tanks, which have about another day left.

Even though they resumed pumping from the river, they asked customers to continue to conserve so they could recharge their storage tanks.

Occidental Water also turned off its Forestville pumps, but continued using its pumps farther downstream, officials said. #

Water emergency declared on Russian River in Sonoma County

Associated Press – 10/24/07

 

FORESTVILLE, Calif.—Officials have declared a water emergency on the Russian River after a black plume of water was spotted near a Sonoma County ranch.

 

Water samples have been sent to a state laboratory for analysis.

 

Dave Evans, a senior engineer with the state Regional Water Quality Control Board, says the runoff from a ranch on Laguna de Santa Rosa caused some discoloration, but there's no indication that the water was a hazard.

 

The water emergency prompted several water districts in the area to shut off its pumps in the area. Local residents have been asked to us water sparingly.

District defends water quality; Tapia says treatment uninterrupted during fire

Ventura County Star – 10/25/07

 

A regional wastewater-treatment system operated continuously during the Malibu Canyon fire emergency and should not be blamed for any water-quality issues in the Malibu area, officials said Wednesday.

 

Local officials issued that declaration after the Los Angeles County Department of Public Health advised people not to come into contact with ocean water in the Malibu area.

 

The Tapia Water Reclamation Facility, which serves an area that includes Agoura Hills, Westlake Village and part of Thousand Oaks, was fully operational throughout the fire, said John R. Mundy, chief administrative officer for the joint powers agency that operates the plant.

 

The Malibu Canyon plant has been a target of critics who question its effects on Malibu Creek and the ocean.

 

"Tapia has continually treated wastewater, and I want to emphasize that there have been no discharges of treated or untreated effluent to Malibu Creek coming from the Tapia facility," Mundy said in a written statement.

 

"While there may be legitimate concerns about contaminants from other sources in the ocean, we believe it's important for the public to know that we have continually treated some 9 million gallons of wastewater each day throughout the fire emergency, and returned that treated water safely to the environment in the form of recycled water for irrigation purposes," he said. #
