PERCHLORATE:

Water funding OK'd; Panel approves money for perchlorate probe

Inland Valley Daily Bulletin – 8/2/07

By Jason Pesick, staff writer

 

Money to investigate perchlorate contamination around Rialto, Fontana and Colton was one of a few projects a congressional committee has approved, Rep. Joe Baca, D-Rialto, announced.

 

A conference committee made up of members of the House of Representatives and Senate approved a number of water projects for the Inland Empire, including money for the perchlorate investigation. The programs are part of the Water Resources Development Act.

 

"I think it's a good move," said Rialto Councilman Ed Scott, who is a member of the City Council's perchlorate committee.

 

Perchlorate, a chemical used in rocket fuels and other explosives, has seeped into Rialto's drinking water from industrial sites in the city's north end. The plume is creeping toward Colton.

 

Local agencies have either shut down contaminated wells or are treating the water so that no contaminated water is served.

 

Perchlorate, if ingested, can affect the functioning of the thyroid and possibly mental development.

 

If both houses of Congress and the president sign off on the legislation, the Army Corps of Engineers would investigate the source of the perchlorate around Rialto, Fontana and Colton.

 

The extent of the contamination is not completely known, and it's not possible to clean it up without first understanding where it is coming from and where it is, Scott said.

 

The amount of money Baca secured for the project was not available.

 

"Whatever it is, it's a step in the right direction," Scott said.

 

The city asked its congressional representatives for almost $12.7 million for an investigation of the Rialto Basin.

 

The projects announced Tuesday as part of the Water Resources Development Act included other Inland Empire projects:

 

Money for the Army Corps of Engineers to improve the Colton Drainage System to prevent flooding and remove storm flows along Valley Boulevard and around Arrowhead Regional Medical Center in Colton.

 

Funding for Ontario's Francis Street Storm Drain and Connectors Project that Rep. Gary Miller, R-Diamond Bar, also requested money for. The project would help reduce flooding, which could hurt Ontario and Chino's dairy industry.

 

Money for Rialto to support the Lytle Creek Groundwater Recharge Project to study Lytle Creek and understand both flooding and water-shortage issues in the creek.

 

The amount of money for these projects was also not available.

 

On Friday, Baca's office announced the House Appropriations Committee's approval of $7.5million as part of the Defense Appropriations Bill. That money included $2.5 million for perchlorate treatment in the area.

 

Rialto also asked Congress for $15 million for the Bunker Hill Water Supply Project to clean water as part of a U.S. Environmental Protection Agency cleanup effort. After the water is cleaned, Rialto and other areas outside San Bernardino would have access to some of it, said Randy Van Gelder, general manager of the San Bernardino Valley Municipal Water District.  #

MERCURY CONTAMINATION:

State investigates for contamination in Lake Chabot; Mercury mine possibly contributing toxins

Vallejo Times Herald – 8/2/07

By Matthias Gafni, staff writer

 

A shuttered mercury mine in the Vallejo hills possibly has contaminated Lake Chabot's fish, a state water official said Wednesday.

 

California Fish and Game and San Francisco Bay Regional Water Quality Control Board officials took fish samples and investigated the area Monday and Wednesday. Lake Chabot, because of its close proximity to St. John's Mine and its state-sponsored fishing program, prompted water board officials to add it to a state survey of lake pollution. In addition, the lake has never been tested before, said water board senior environmental scientist Karen Taberski.

 

"We anticipate large mouth bass in Lake Chabot will have levels higher than our screening values," Taberski said, referring to levels used to set up health advisories.

 

Officials took bass and carp samples Monday to test for mercury. As a predator high on the food chain, older bass are good indicators for mercury levels, Taberski said, while carp, as bottomfeeders, often show organic contaminants such as DDT. The results are expected in several months, she said.

 

On Wednesday, investigators revisited the lake and discussed mercury mine history with Solano Historical Society members.

 

Taberski said officials determined the Lake Chabot watershed most likely received mercury contamination from the former St. John's Mine. Coincidentally, water board officials have been investigating north Vallejo's mysterious mercury mines after the state announced tighter restrictions on mercury limits in San Francisco Bay last month.

 

The Lake Chabot examination is part of the Surface Water Ambient Monitoring Program, which will investigate about 250 lakes statewide for mercury pollution, including Lake Berryessa. There are about 10,000 lakes throughout the state, and many in Northern California have mercury contamination, often from naturally occurring geology, Taberski said.

 

Scientists have determined that eating large amounts of mercury-laden fish can cause health problems. Signage lines many Bay Area waterways warning fishermen to monitor fish consumption, including Lake Herman.

 

The Benicia lake, on the state's list of impaired waters, was last checked in 1998. Signs warn the public to avoid eating fish from that Lake Herman, which receives mercury contamination from another old Vallejo quicksilver mine.

 

Doug Darling has long volunteered cleaning Lake Chabot and assisting with the Intercity Fishing Program, which has done a half dozen fish plants in the last 18 months. Those introduced fish come from hatcheries, Darling said.

 

The Greater Vallejo Recreation District hosts an annual catch-and-release Gone Fishing Derby at Lake Chabot for ages 5 to 15.

 

Since the fish drops began, Darling said fishing has quadrupled at the lake. Even though the recent tests may bring bad news, he welcomes state officials.

 

"It's far more important that the public is aware of any mercury levels than keeping the Intercity Fishing Program," Darling said.

Of course, catch and release at the lake will remain unaffected either way, he said.

 

"It's important we're not inducing fear and alarm, because it has to do with fish consumption," Darling said. "Regardless of the outcome (of the mercury testing), recreational fishing is still a great use of the lake." #

WATER LEAKAGE:

Newmont told to find water leak; Grass Valley hoped for cease and desist order in lawsuit

Grass Valley Union – 8/2/07

By Greg Moberly, staff writer

 

Owners of an abandoned mine allegedly leaking large amounts of water into the Grass Valley's sewer treatment plant need to pinpoint where the water is coming from, according to orders from the state's Regional Water Quality Control Board.

The latest order issued to Denver-based Newmont Mining Corp. is part of an ongoing dispute between the city and the mining company about tough-to-treat mine water. The city already has paid $1.5 million pursuing a lawsuit and negotiating with Newmont, as well as more than $1.5 million to treat the mine water.

The mine water contains iron and manganese, which are hard to treat, city public works officials said. The water has spilled into the city's sewage treatment plant since 2000. Nearly 500,000 gallons of water a day flow into the treatment plant from the abandoned mine, city officials said.

Newmont officials don't admit that the water comes from their abandoned mine, but they agreed to follow the state board's order, state water quality officials said.

"Newmont remains committed to working with the city and the Regional Water Quality Control Board, and we appreciate the opportunity to collect additional data needed from the site, Newmont said in a statement Wednesday. "We hope this new data - along with the information we've already collected - provide a sound technical basis for developing an appropriate management strategy for the discharged water."

The state's order, while important to Grass Valley city leaders in its ongoing dispute with the deep-pocketed mining company, is less than what the city wanted.

"It's a little disappointing," said Interim City Administrator Jeff Foltz. "I was hoping for a cease and desist order."

State water quality officials issued a draft cleanup and abatement order in May, but after receiving comments from the mining company, they decided it's better to focus on the source of the mine water "at this time," according to the board's order.

"It would be a lot cheaper if you could divert water from flowing into the mine," said Steve Rosenbaum, senior engineering geologist for the state Regional Water Quality Control Board.

"This is the first half of that cleanup and abatement order," Rosenbaum said. "It's better to find the problem and fix it," he said. The next steps would be determined after Newmont's findings are revealed, he added.

The mining company has until the end of May 2008 to finish its investigation and report back to the board, according to the order.

It's frustrating for the city because it ensures the issue won't be resolved soon, Foltz said.

"Another year of looking at the problem is frustrating," Foltz said.

The city's federal lawsuit with the mining company, set for trial in September, has been pushed back to March. #

WASTEWATER POND:

Windsor to add wastewater pond; Project will require removal of 1,200 oaks; council says many other trees on site will be saved

Santa Rosa Press Democrat – 8/2/07

By Clark Mason, staff writer

 

After years of stalling, Windsor is going ahead with plans to build a badly needed wastewater pond in a tree-studded valley southwest of town.

The Town Council on Wednesday approved the first steps for constructing a 215-million-gallon, 26-acre pond that will require cutting down more than 1,200 trees.

The town, which has an oak tree for its logo, has until now postponed adding wastewater storage, in part because of the number of oaks and other trees that will be lost.

"All of us have been on hikes up there. In the valley where the pond would be, it's pretty studded with mostly big oaks," said Councilwoman Debora Fudge. "It's a hard pill to swallow to lose so many trees."

But council members are planning to lessen the loss by preserving in perpetuity many of the surrounding trees on the 168-acre property the town owns.

Consultants said that in all, there are more than 5,600 trees on the site.

Mayor Warin Parker said he is hoping a system of public trails can be developed near the pond, which would hold highly treated, near-drinkable wastewater for irrigation.

Since the early 1990s, Windsor has owned the land off Eastside Road and set it aside for future wastewater storage, but has postponed committing to construction.

The town was looking at alternatives, such as shipping the wastewater through the city of Santa Rosa's nearby pipeline that runs to The Geysers geothermal field where the wastewater is injected into the steam field. Windsor officials are still looking at that as an option to reduce some pressure on their system until the new, $29 million pond is built and goes into service in 2011.

The town needs extra storage to accommodate growth and provide more flexibility for the weather-driven system.

"We're basically out of capacity," said Wilhelm Daida, assistant town engineer.

Public Works Director Richard Burtt said Windsor, just as Santa Rosa, needs additional storage capacity for wastewater, which is becoming a more valuable resource.

"There's more and more of a demand because potable water is in such short supply," he said.

Annually, the town treats about 650 million gallons of recycled water and reuses more than half through urban and agricultural irrigation. The rest gets discharged into Mark West Creek, a tributary of the Russian River.

The highly treated wastewater irrigates vineyards, pastures, the golf course, high school, parks and the Town Green.

But Windsor wants more storage to be able to hold the wastewater at times when irrigation is impractical, or when it cannot discharge into the creek.

The option approved Wednesday will be financed through a combination of grants, increased utility rates and new connection fees, subject to future council approval.

Town officials said the new storage pond may also be shared by Santa Rosa and the county water agency, which are also looking at sites in the northern part of the county for storage. If the town decides to partner with other agencies for the project, they could share some of the cost.

There is also the possibility the town could build a second storage pond in the future at the Eastside Road site. But the 4-0 vote Wednesday authorized town staff to proceed with preliminary design and supplemental environmental studies for just one pond. #

CLEAN WATER ACT:

EPA cites six SoCal dairies for Clean Water Act violations

Associated Press – 8/1/07

 

LOS ANGELES—Federal regulators cited six Southern California dairies for violating clean water rules designed to prevent the facilities' animal waste from polluting local water supplies, officials said Wednesday.

 

The dairies were ordered to repair leaks in waste lagoons, build raised barriers around the lagoons, arrange to remove manure piles and make other changes to comply with the law, U.S. Environmental Protection Agency scientist Glenn Sakamoto said.

 

Regulators said runoff from the facilities could pollute the Santa Ana River. The dairies were cited for violations of state-issued permits that include failing to contain on-site manure, execute waste management plans, and design and manage manure-containment structures, the EPA said.

 

The facilities could face fines of up to $32,500 per day per violation if they don't make needed fixes and as a result pollute streams, rivers or groundwater, Sakamoto said.

 

"We're hoping and trust that dairymen want to do what's best to protect the environment," Sakamoto said. "If the acts continue and it results in a discharge, we may look at the next step, which would be penalties."

 

Representatives for the dairies—identified as Legend Dairy #1, Legend Dairy #3, Sun Valley Jersey Dairy #1, Miersma Dairy #1, Tom Alger Dairy and Venegas Dairy—did not return messages or could not be reached for comment.

 

The orders were issued based on a March 2007 EPA inspection of the dairies, which are located in Chino, Ontario and Mira Loma.

 

Michael Marsh, who leads the trade group Western United Dairymen, said the organization would work with the dairies to bring them into compliance.

 

"Dairy producers have got to follow clean water and clean air laws," he said. "We take the business of keeping the environment clean very seriously."

 

In 2000 and 2001, the EPA fined numerous dairies in the Chino area for similar Clean Water Act violations, officials said. #

WELL WATER:

Nitrates nag city; Live Oak reduces work on water

Marysville Appeal Democrat – 8/2/07

By Robert LaHue, staff writer

 

Live Oak is scaling back its arsenic removal project after high nitrate levels were found in one of five city wells.

The additional treatment required to bring the well up to standards cannot be covered by $2 million in grants the city received to fix the arsenic problems, Public Works Director Michael Bohlander told the City Council on Wednesday night.

The council unanimously voted to negotiate with the low bidder for the five-well treatment project – Waterworks Construction Inc. – for a four-well job.

“Early indications are they’re OK with that,” Bohlander said of the contractor.

The project was spurred by the tightening of arsenic levels in drinking water by the Environmental Protection Agency in January 2006 from 50 parts per billion to 10 ppb, an amount a city consultant said equaled a drop of water in a pool.

Live Oak’s drinking water averages 20 to 30 ppb, a level not considered a major health problem. The city has until September 2008 to comply with the federal standards.

The city applied for funds on an arsenic treatment program through Proposition 40, approved by state voters in 2002. Of $9.5 million in arsenic reduction money available statewide, Live Oak received $2 million.

Bids for treating five wells with a filtration system from seven companies ranged from $3.52 million to $2.6 million. Estimates earlier this year had the project being fully funded by the $2 million grant.

“I about passed out reading those numbers,” Bohlander said.

Then came the nitrate discovery, which forced City Well 5 to be taken offline entirely.

While numbers are not official, Bohlander said taking the fifth well out of the project will bring the contract down to around $2.1 million.
Bohlander said even with the lower number, $2.5 million is the target cost for repairs. The grant is not in danger because of the project change.

The city applied Tuesday for a different grant to correct the problems with Well 5 through Proposition 84, the 2006 measure which approved $5.4 billion in bond funding for water supply, flood and other natural resource issues.

“Hopefully, we’ll be able to get that grant to get back to five wells again,” Bohlander said. #
