Old Pesticide Manufacturing Site Has Imminent Cleanup

By: Duane Craig


Contaminated land on Whiteford Road in Whiteford, Md., nears a cleanup, according to this article. The soil on the site is laced with arsenic left behind from a chemical and fertilizer manufacturer.

Up until 1976, the manufacturer released waste from its mixing operations into a pond on the property. The waste then flowed through a ditch and into a nearby stream. While the chemical operation stopped using the pond in the 1970s, the adjacent packing company continued to use it for years afterward.

On the soil’s surface, arsenic has been recorded at 459 parts per billion, while deeper down it reaches as high as 1,660 parts per billion. The Environmental Protection Agency lists arsenic’s safe level in ground water as 10 parts per billion. The manufacturing of various pesticides and fertilizers was stopped in the mid-1980s and demolition waste from the building was dumped into the pond. The Maryland Department of Environment actively sampled for contamination in 1984 and in 2001. After in-depth studies of the properties between 2005 and 2008, the agency badgered potentially responsible parties to make plans for the cleanup.

Cleanup plans were completed by 2009. During the past three years, the responsible parties have been gathering permits, approvals, waivers and access agreements so the work could begin.

California Community Pestered by Pesticide-Tainted Water

By: Duane Craig

Every residential property in Livingston, Calif. that relies on water from city-owned wells can now expect 1,2,3-trichloropropane to be present to some degree in that water, according to an article in the Merced Sun-Star. Livingston’s water supplies have also had problems with elevated levels of arsenic and manganese.

Some local officials appear to be hoping the community accepts the long-term contamination prospects as well as they have. One councilman played down the threat saying it wasn’t serious and that levels of 1,2,3-trichloropropane fluctuate. He said he continues to use the city’s water and also gives it to his children. Another official pointed out the chemical, related to agriculture, had been widely used in the area and had prompted other communities to sue companies that produced and used it.

Livingston itself sued and received a $9 million settlement from companies that participated in the contamination, and local officials say the money is being used to clean up the problem. One approach under development is a specially-designed filter that will remove the chemical. The first of its kind is expected to be completed in fall of 2012.

Livingston is one of many communities across California dealing with the chemical. Its shortened name is 1,2,3-TCP and it was originally found at a Superfund site in the southern part of the state, according to information at the California Department of Health. At about the same time it was found in several wells across the state and in 2009 the U.S. Environmental Protection Agency reported its link to cancer in studies involving laboratory animals. The chemical was used to remove paint and varnish, to clean and degrease materials, as a cleaner during maintenance activities and as an intermediate chemical. It is a byproduct in the manufacture of pesticides based on dichloropropenes, and is used to make soil fumigants.

Land throughout the area near Livingston is heavily used for agricultural purposes leading many to think that its problem is related to pesticide use. Livingston is in Merced County and that county has 25 instances of 1,2,3-TCP being detected in water sources, but the number of detections is on the low side compared to other places in California. For example, Kern County has 108 detections, followed by Los Angeles with 46. Altogether California has 336 sources of water where 1,2,3-TCP has been detected. Still, that might be an optimistic measurement of the potential problem since it doesn’t include 36 inactive, abandoned or destroyed water sources, and doesn’t include agricultural water sources and monitoring wells.

Pesticide Becomes Florida Community's Pest

By: Duane Craig


As DeLand, Fla. recently learned, there is no escaping the consequences of trying to control the environment, and the living things within it. Comfortable residents, some with golf course views and many with country club memberships in the Country Club Estates community now know one of the true costs of striving for a bug-free environment.

The pesticide, dieldrin, has been found in nearly 50 percent of the wells tested, driving 118 homeowners to ask to be connected to city water. Meanwhile, 80 homes are in the process of being connected, and the property values in the community have dropped 50 percent, according to this report.

The pesticide is widely used to control termites and other pests at the residences, is used at the nearby golf course and was stored and mixed at a pest control business at U.S. 17-92 and Orange Camp Road. To be on the safe side, residents have been encouraged to have wells tested regularly, garden in above-ground containers, use masks for mowing lawns that have sandy spots, and limit children playing in the yards.

Two canals in Michigan are dangerously contaminated with polychlorinated biphenyls, or PCBs, according to this advisory. The seriousness of the contamination was underscored by the Michigan Department of Health when it wrote in the advisory that the PCB levels were 2,000 times higher than those typically seen in fish taken from Lake St. Clair. The advisories cover the bottom feeders -- carp and catfish. That’s because they feed closest to the contaminated sediments and have high concentrations of body fat to store the PCBs. The canals affected are the Lange and Revere off Lake St. Clair. Residents who live along the canals are concerned about how long it’s taking to find the source of the contamination. The Environmental Protection Agency has been sampling and cleaning up problem areas for years but hasn’t been able to determine just where the contamination originated. PCBs have been linked to cancer and are a persistent pollutant, meaning they accumulate in the environment and in the tissues of living things.


Water well contamination in Stamford, Conn., is raising the specter that there may be extensive contamination of wells throughout the state, according to this article. Private water well testing in the city has revealed 31 percent of those tested are contaminated with chlordane and dieldrin, two pesticides banned a long time ago.

A representative of the state’s department of health said her department thinks the problem is more widespread than just Stamford. Other communities, however, are not responding to calls for testing within their jurisdictions. Some believe that’s because of funding issues and the effect on property values if the pollution is found.

Of the 628 wells tested in Stamford, 195 had levels of the pesticides, and 108 exceeded the action levels established by the state. There are another 5,000 private wells in Stamford, and that is raising concerns about how many people are potentially being exposed to the chemicals over long periods of time.

Chlordane and dieldrin were usually used to control insect pests on crops and to control termites. People are exposed to the chemicals when they drink or bathe in water containing them. People can install whole house water filters to take care of the problem. Health officials point out that the levels of the pesticides can fluctuate, so unless regular sampling is taking place, it’s not possible to know just how much exposure people are getting.

NYC's Newtown Creek Declared Superfund Site

September 27, 2010 - The Environmental Protection Agency today declared toxic Newtown Creek a federal Superfund site after a series of soil and water samples were tested over a three-month period in 2009. Superfund sites are former industrial areas so polluted they are determined to need federal funding for cleanup. The creek, which serves as the border between Queens and Brooklyn, joins the Superfund list as one of seven added today by the EPA.

Testing revealed the presence of pesticides, metals, polychlorinated biphenyls (PCBs), and volatile organic compounds (VOCs). PCBs are thought to cause a range of health issues in humans, and VOCs can cause respiratory, allergic, or immune problems.

Citing the toxic site as one of the most polluted water bodies in the country, officials including local Congress members Anthony Weiner and Nydia Velazquez pushed the EPA to test the waterway, which flows partly under the north end of Bushwick as English Kills.

Arsenic, Pesticides Found at Phipps Ocean Park, FL

August 10, 2010 - Arsenic and pesticides have been found in two areas at Phipps Ocean Park, and the cost to remove it could range from $500,000 to $600,000, Public Works Director Paul Brazil told the Town Council Tuesday.

More areas may need decontamination as well, he said.

"It isn’t the Love Canal, but we have a contamination issue that we need to deal with," Brazil said. "We don't know the extent of it right now."

He said high concentrations of arsenic and dieldrin, a chlorinated pesticide, were discovered in soil and groundwater samples taken during the removal of a diesel fuel tank and underground waste-oil storage tanks at the town's waste-water pump station at Phipps.

The fuel tank, used to operate an emergency generator, and the storage tanks were replaced as part of an improvement project.

A contractor placed temporary fencing around the main contaminated area — the grounds immediately surrounding the pump station — after the contamination was detected, Brazil said.

DDT Contamination Lingers At CA's Inner Richmond Harbor

July 14, 2010 - Talk to those who frequently fish in San Francisco Bay and you'll find many who keep and cook their catch. But -- as area fisherman Anthony Florez noted -- it's best to limit the amount you consume.

"You can eat them. But you can't eat too much of it, you know?" said Florez.

Warning signs posted by the state make the danger clear. Mercury and other toxins have been found in the fish. And there is a spot in the bay where no fish are fit to eat. It is a large part of the Inner Richmond Harbor. The main contaminant is DDT, the once widely used pesticide.

"We want the communities to be aware of existing do not eat advisories in the Richmond harbor area and follow these advisories very closely," said Sharon Lim, Environmental Protection Agency project manager for the United Heckathorn Superfund Site.

United Heckathorn was a major pesticide manufacturing plant. Decades ago, it sandwiched between 4th Street in Richmond and the Lauritzen canal.

The plant is long gone, having been demolished after the company went bankrupt in the 1960's. But the company left a legacy of toxins that continue to threaten people and the environment.

Private Wells In Connecticut Contaminated

September 24, 2009 - Twelve private wells in Stamford, Connecticut tested positive for contamination and will be outfitted by the state DEP with charcoal water filters, and the city promised the same setup for any resident up to three houses away who requests it.

The trouble began last fall when an EPA study identified unsafe level of contaminants, including banned pesticides from the '70's, in the soil under Scofield Park in northern Stamford.

Pesticide test results galvanize neighbors in Stamford, Connecticut

September 4, 2009 - The latest revelation that some private wells near Scofieldtown Park are contaminated with toxic pesticides levels has galvanized the neighborhood to action.

This summer, the city and state launched tests of private wells in the area in response to a federal study showing unsafe levels of contaminants in soil within the park, a site used as a landfill from the 1930s until the early 1970s.

Most, if not all, homes in the immediate vicinity are not connected to water lines and use private water wells. The city found two pesticides on Hannahs Road and Very Merry Road that are above levels that the state deems may be harmful to human health.

New Jersey Homeowners Learn Developer Built on Contaminated Soil

August 4, 2009 - Homeowners in Montville, New Jersey, learn that their upscale development had been built on pesticide-contaminated soil from a former apple orchard.

New Jersey and other states have laws that require property owners to notify potential buyers if a property is near a former toxic waste site, for example, but those laws generally don't apply to farmland where pesticides were used.

North Carolina peach orchards land contaminated

September 20, 2008 - Millions of years after ancient oceans receded, the rolling dunes called the Sandhills offered well-drained soil and frost protection for what would become North Carolina's peach belt.

Many of those orchards have faded away, but their legacy haunts the people who claim the sandy soil. Their groundwater is contaminated by pesticides that may cause cancer.

Tests have found 117 tainted wells in Montgomery, Richmond and Moore counties in the past year, 77 of those at unsafe levels. The number continues to grow as alarmed residents have their water analyzed.

Santa Clara County Leads California In Contamination From Old Orchards

October 19, 2007 - Santa Clara County's most neglected environmental problem sits right under our feet.

While officials have spent decades cleaning up toxins from the technology industry, no state or county agency has tried to gauge the scope of an older hazard - agricultural pesticides left by the farms and orchards that once covered Silicon Valley.

Santa Clara County has more toxic cleanup sites involving old orchard pesticides than any county in California, as well as a significant number of other sites contaminated by other types of farming or pesticide handling, according to a Mercury News analysis of state records.

Pesticide Spraying on Farms Impacts Neighboring Residents

May 16, 2007 - THE SPRAYING starts at night, tractors pulling fans that blow the neurotoxin over the tops of dense, leafy orange trees.

The trees surround this tiny farm community deep in the San Joaquin Valley. The chlorpyrifos — banned for domestic use since 2000 yet still used widely on crops — falls like a lethal mist, first paralyzing, then killing insects seeking a portion of Tulare County's $4.3 billion in agriculture sales.

But the nights are hot, the fans are powerful, and the mist travels.

And so, invariably, swamp coolers straining against the smoggy heat pull the poison into Lindsay homes.
