PUBLIC HEALTH: Feinstein calls for Barstow water probe

PUBLIC HEALTH: Feinstein calls for Barstow water probe


Bookmark and Share


Sen. Dianne Feinstein is calling upon the State Water Resources Control Board to conduct a review following the recent discovery of a rocket fuel additive in Barstow-area wells.

Just before Thanksgiving, the Golden State Water Company detected the chemical perchlorate at 20 parts per billion in its water supply, according to a letter to be issued Friday by the California Democrat. The California state limit is 6 parts per billion.

Subsequent testing in the area found high levels of perchlorate in one public well and extremely high levels in two private wells, Feinstein noted in the letter to Charles R. Hoppin, the board's chairman.

"It is estimated that there are 40-50 Barstow residents relying on private wells in the area of the plume," she wrote. "This is a short term situation that deserves immediate attention to assess whether their water is safe."


Former fireworks maker suspected in Barstow's water contamination

Former fireworks maker suspected in Barstow's water contamination

A former fireworks company has emerged as the potential source of a chemical that last month contaminated public water supplies in the Barstow area, making tap water undrinkable there for as many 40,000 people for several days, say state water quality control officials.

The Mojave River Pyrotechnics Co. closed its doors in Barstow in the mid-1980s, but records kept by the U.S. Environmental Protection Agency showed that it had received shipments of perchlorate, an explosive salt used to make fireworks, ammunition and solid-state rocket fuels, say state officials.

The company had operated near a drinking-water well in north Barstow that last month was found to be producing water with 100 parts per billion of perchlorate -- more than 16 times the allowable limit for drinking water. And tap water at the Marine Corps Logistics Base, just east of Barstow, was found to have perchlorate at more than three times the legal limit of 6 parts per billion.

These discoveries prompted Golden State Water Co. to close the well and issue a "no drinking order," forcing Barstow area residents to rely on bottled water, while the company worked around the clock, flushing perchlorate-tainted water out of the system's network of pipes.

The area is now using water drawn from other wells. The company provides the Barstow area with its water.

Harold Singer, executive officer of the Lahontan Regional Water Quality Control Board, said this week that the EPA is assisting with the state investigation of the source of the perchlorate. He emphasized that Mojave River Pyrotechnics is now suspected only because EPA records indicate it had used the chemical.

"Completing the investigation may take months," he said.

So far Lahontan officials have tested 26 privately owned wells and found two with levels above the legal limits in an area north of the town's center and above the Mojave River, Singer said.

Further work will likely include drilling test wells to help pinpoint the source, he said.

During the "do not drink" order, city and company officials set up bottled-water distribution centers and established a hot line to report shut-ins and others who might not have been able to get safe water. Police delivered bottled water to those in need.

In addition, the San Bernardino County Board of Supervisors also proclaimed a local emergency, making the county eligible for reimbursement of three-fourths of the cost of helping Barstow with logistical support, restaurant inspections and ferrying water samples to a laboratory in Orange County.

In sufficient concentrations, perchlorate is known to disrupt the thyroid gland's ability to absorb iodide, which is needed to make the hormones that guide brain and nerve development of fetuses and babies. It also can be harmful to people with iodine deficiencies.

California has regulated the chemical's quantities in drinking water since 2007.

On another note-- Hinkley chromium clean-up could take more than a century

Hinkley chromium clean-up could take more than a century
By KAREN JONAS, staff writer
HINKLEY • The Lahontan Regional Water Quality Control Board will be deciding soon if an expansion to the treatment of the chromium 6 water plume in Hinkley will be put into place, but residents probably won’t see the results in their lifetimes.
Pacific Gas and Electric is proposing to expand its current operation of injecting the chromium 6 tainted water with ethanol to convert it to the less dangerous chromium 3. In a feasibility study done by the water board, the ethanol treatment would probably take about 150 years to restore chromium 6 levels to the naturally occurring levels of 3.1 parts per billion.
The feasibility study done by the water board shows that the removal of the chromium 6 tainted groundwater will take more than 100 years, even with the most effective treatment.
PG&E is currently injecting ethanol into the plume in order to convert the chromium 6 into chromium 3, which is much less toxic. The company pumps contaminated water out and sprays it onto alfalfa plants so that it will not be spread through the air. PG&E also injects clean water as part of the program to cleanse the groundwater.
The expanded program will include increased pumping and will occur over a larger area, said Lauri Kemper, assistant executive officer for the Lahontan water board.
Kemper said the program was chosen out of five different alternatives because PG&E had tested a variety of treatments over the years, and the ethanol treatment worked best with higher concentrations of chromium 6.
The plume of contaminated water has been slowly growing and is now about two miles long and nearly a mile wide.
PG&E has been ordered by the water board to clean up the chromium 6, but the plume continues to grow.
Jeff Smith, a spokesman for PG&E, said PG&E was committed to the clean-up in Hinkley.
“We’ll do whatever is necessary to clean up the Hinkley area,” said Smith.
Carmela Gonzalez, a Hinkley resident who has been trying to get Hinkley’s water cleaned up, said that the proposed effort was not good enough.
“The public needs to say that over a hundred years is out of control,” said Gonzalez.
Gonzalez urged residents of Hinkley to attend a public information hearing that will be held on Wednesday
“The public needs to contact the water board,” said Gonzalez.
The Hinkley water situation became famous after legal aide Erin Brockovich helped win a settlement against PG&E worth $333 million for the residents of Hinkley who had been sickened by tainted water. The battle became the source of the Oscar-winning film “Erin Brockovich.”
PG&E used chromium 6 over fifty years ago to prevent rust in cooling water towers in Hinkley. The wastewater was discharged into unlined ponds, where it eventually seeped into the groundwater in Hinkley.
Chromium 6 has been shown to cause oral and intestinal tumors in rats and mice when ingested, according to studies done by the National Toxicology Program.

Private wells contaminated

(Best Syndication News) Barstow, CA - Groundwater in a limited area of Barstow that serves individual wells contains perchlorate above the California drinking water standard (maximum contaminant level or MCL). Property owners with wells in an area between I-15, the Mojave River, Old Highway 58 and Leona Road will receive individual notification if their wells have been tested for perchlorate. Contamination above the MCL has been found in two residential wells on River Road, south of Poplar Street. No other residential wells tested show perchlorate contamination.

The CA Department of Public Health has determined that the water being provided by Golden State Water is safe.


The Lahontan Regional Water Quality Control Board (Water Board) has evaluated the results of analysis of 26 representative private wells in the vicinity of the public water supply wells that caused the now rescinded "Do Not Drink" alert for customers of Golden State Water Company. Based on the latest test results, it appears the perchlorate groundwater contamination is currently limited to the area mentioned above.

Based on these limited results, groundwater in areas surrounding the affected area shown in the attachment is likely not contaminated with perchlorate.

The Water Board, with the assistance of federal, state and local entities, has initiated an investigation of the former Mojave River Pyrotechnics Company as a potential source of the perchlorate contamination. This company ceased operation in the mid 1980's. The location of this operation provides additional evidence that private wells outside of the area described above map are not likely contaminated with perchlorate.

The Lahontan Regional Water Quality Control Board's mission is to preserve, enhance and restore California's water resources and ensure their proper allocation and efficient use for the benefit of present and future generations.

Investigation into perchlorate source could take months

Investigation into perchlorate source could take months
By KAREN JONAS, staff writer
BARSTOW • Water board officials will continue their investigation into locating the source of the perchlorate contamination of Barstow’s tap water but say it is a long and complex process that could take months.
The Lahontan Regional Water Quality Control Board is heading up the investigation and has already named a potential source of the contamination. Singer said scientists are investigating the site of Mojave River Pyrotechnics to determine if the perchlorate contamination originated from the former company, which closed in the 1980s.
The water board is testing private wells to get more information about the source of contamination. After testing a total of 26 private wells for perchlorates, Harold Singer, the board’s executive officer, said two wells showed levels of perchlorates higher than those allowed by state drinking water standards.
Singer said investigations into the source of a contaminant usually start with looking for companies in the area that might have used the chemical for business either in the past or at present. Mojave River Pyrotechnics used to produce fireworks, which contain perchlorates.
The Lahontan water board will be conducting further tests of private wells in the area this week so that they can more accurately pinpoint the source of contamination. The Mojave Water Agency and Golden State Water Company will also be working with the Lahontan water board to find a source.
Lance Eckhart, principal hydrogeologist for MWA, said determining the extent of a plume of contaminated water can be difficult when drawing water from wells because wells are often drilled into different aquifers, or bodies of groundwater underneath the surface. Eckhart said there could be multiple layers of aquifers underneath the surface and a well could be drawing water from multiple aquifers, depending on how deep the aquifers lie and how deeply the well is drilled.
Determining the flow of groundwater can also help accurately pinpoint a source of water contamination. Singer said the water board would be doing an analysis of groundwater flows to see how quickly the groundwater was flowing to determine how quickly the contaminant could have spread. Eckhart said the natural flow of groundwater was slow, but said it could move faster if the water was being pumped.
Finding the source of the contamination means that the water company can determine the person or company responsible for the contamination. Singer said the water company would then have the company that polluted the water pay for further investigation of the extent of the plume. He said if there was not a responsible party for the contamination, then different state and federal programs would help continue the investigation.

Perchlorate contamination found in residential wells


BARSTOW – Additional tests have disclosed that the perchlorate contamination in the drinking water extended beyond wells used by the Golden State Water Company.

The Lahontan Regional Water Quality Control Board said the groundwater contamination also showed up in individual residential wells. At least two wells along River Road tested positive.

Property owners with wells in an area between I-15, the Mojave River, Old Highway 58 and Leona Road will receive individual notification if their wells have been tested for perchlorate.

Based on the latest test results, it appears the perchlorate groundwater contamination is currently limited, according to the water board.

The State Department of Public Health has determined that the water being provided by Golden State Water is safe. But, an investigation into the source of the contamination continues. (INT)

Barstow veterans thankful water now safe to drink


Andrew Edwards Staff Writer

BARSTOW - One day after the lifting of a citywide "do not drink" order for tap water supplies, the war veterans who call this Mojave Desert city home were able to celebrate Thanksgiving without having to rely on bottled H2O for basic needs.

Barstow's water supplies were officially unsafe for about one week after the discovery of perchlorate, a contaminant used in the manufacture of rocket fuel, weapons and fireworks, was discovered in nearby wells.

"They told us not to bathe, wash clothes, brush teeth, anything," said Ramiro "Rudy" Rueda, a 77-year-old Army and Air Force veteran who served during the Korean War.

Rueda has lived at the Veterans Home of California, Barstow since February 1996, he said.

He and some other residents described the past few days' lack of drinking water as a minor convenience. The experience was not the first time he and other combat veterans there had to survive without pristine water supplies.

"I was in World War II, and we used to have pills sometimes for the water," said George Warren, an 88-year old veteran of the U.S. Army Forces in the Pacific Theater.

Warren served as an aircrew member aboard B-24 and B-25 bomber aircraft and still has the metal aircrew badge he earned in 1943.

While at war with Japan, he and his compatriots had to make do with whatever water was available in places such as Papua New Guinea, the Philippines and Okinawa.

Barstow's do not drink order was issued Nov. 19, and the Veterans Home was the last

place in town where state public health officials and Golden State Water Co. cleared water supplies for human consumption.

The OK announcement for the Veterans Home came out around noon Wednesday, about 14 hours after the rest of Barstow was freed from the do not drink order.

Veterans Home staffers also received instructions to flush out water pipes, ice-makers and filtration equipment.

While the order was in effect, Veterans Home administrators relied on emergency water supplies and stocked up on bottles and 5-gallon containers of the liquid to keep the center, which serves 189 veterans, running.

The kitchen required 70 gallons of bottled water per day, administrator Art Robles said.

By Thursday, some of the remaining containers were stashed out while the veterans gathered to dine on turkey, ham, mashed potatoes, and other traditional foods.

"It's good. The food is always good here, and this is excellent," said Warren, whose plate was stacked high with the day's repast.

Warren also said he had a big stack of laundry that piled up while water was off limits.

The perchlorate contamination was discovered last week when test results of water supplies sampled in August at Marine Corps Logistics Base came back positive for perchlorate. A retest showed perchlorate levels were above the legal maximum.

Gov. Arnold Schwarzenegger declared a state of emergency on Saturday, and city and state officials distributed bottled water to Barstow dwellers while the do not drink order was in place.

The cancellation of that order has not convinced all Barstow residents that their tap water is safe for drinking and other other domestic uses.

Top Hat Liquor on Main Street sold its entire stock of bottled water on Friday, manager Mike Elkamel said. Sales have slowed down, but he said some customers are still unwilling to drink from the tap.

"They don't trust what the media said, that the water is safe," Elkamel said.

Arturo Martinez, a 51-year-old Federal Aviation Administration employee, is but one person in Barstow who is still suspicious of the town's drinking water.

"I don't feel comfortable drinking the water," he said. "I'm not going to cook with it. To be honest with you, it's a done deal.

"Most people are not satisfied because they have to shower in the water," Martinez added. "We're not even brushing our teeth with the water. We're using bottled water."
