Wastewater Issues Get Wormy
Recent research indicates that earthworms may be an important initial step by which organic contaminants could enter the terrestrial food web. Wastewater treatment plants process millions of gallons of mixed solid and liquid human waste daily, returning treated effluent to surface and ground water and disposing of the residual sludge. Roughly half of the many thousands of dry tons of treated sludge (usually referred to as biosolids) generated annually in the U.S. are applied to agricultural soils as a nutrient-rich soil amendment. Recent USGS research has identified a wide variety of organic contaminants (such as disinfectants, pharmaceuticals, synthetic fragrances, and plasticizers) that can be present in biosolids, often in concentrations tens to thousands of times higher than found in treated liquid waste. One concern related to the practice of land application of biosolids is whether any of these organic contaminants find their way into soil-dwelling organisms. To address this concern, USGS and Eastern Washington University scientists collaborated on a study of earthworms collected from agricultural soils in the Midwest and Western United States that had been exposed to land-applied biosolids. The samples were analyzed for a diverse array of pharmaceuticals and other organic contaminants (77 target compounds were measured). Soil and earthworm samples were collected from select agricultural fields early and late in the growing season. Thirty-one compounds including triclosan (household disinfectant), several fragrances, caffeine, and fluoxetine (the antidepressant Prozac) were detected in earthworms from biosolid-applied fields, with tissue concentrations ranging from 100’s to 1000’s of micrograms per kilogram (parts per billion). These results demonstrate that earthworms can accumulate a range of these chemically diverse organic contaminants within their tissues, and may be an important initial step by which these compounds could enter the terrestrial food web.

Contaminants Lower Reproductive Health of Gila River Fish
Downstream of Phoenix, southern Arizona’s Gila River is primarily recharged by irrigation return water, storm water, and wastewater treatment plant effluent, and fish and aquatic invertebrate habitats are degraded. Largemouth bass, common carp and channel catfish from the Gila had elevated levels of organochlorine pesticides, many of which have been associated with estrogen-like effects in fish. Reproductive biomarkers, including gonad size and hormone concentrations, were notably different in fish from the Gila River when compared to fish from the Colorado River, indicating that organochlorine contaminants may be affecting the reproductive health of fish populations in the Gila River downstream of Phoenix.

Rocky Mountain High — Mercury in Cold Environments of the Western United States
Atmospheric deposition of mercury in remote areas in the Western United States is sufficient to pose a risk to human and ecosystem health at sites favorable for methylation, a process in which mercury in the environment is converted into a highly toxic form that accumulates in organisms and is amplified up the food chain. USGS researchers and partners measured mercury in snowpack samples during 2003-2005 as part of the National Park Service Western Airborne Contaminants Assessment Project. Eight high-altitude, high-latitude sites were selected for study in or near national parks in Colorado, Montana, California, Oregon, and Alaska. Mercury levels were lowest in the North Cascades, highest in the Rocky Mountains, and were related to the amount of particulate carbon in the snow, with both found at higher levels in forested sites than in open meadows. Seasonal variations were lowest in Denali National Park and highest in Olympic National Park. Mercury concentrations were higher during the warm season than the snow season. Total annual fluxes of mercury were as high as 10 mg m-2 at some sites in the Rocky Mountains, which receive mercury deposition equal to that in the Upper Midwest or Northeast. Global and regional sources of mercury emissions contribute to its deposition, with regional sources likely contributing more in the Rocky Mountains, where there are more upwind sources of emissions.

Pharmaceuticals in Long Island’s Groundwater
Pharmaceuticals can infiltrate groundwater systems in areas susceptible to wastewater contamination. In studies by Stony Brook University and the U.S. Geological Survey of ground-water wells in Suffolk County, Long Island, NY, near permitted wastewater treatment facilities discharging to ground water, scientists detected pharmaceuticals in concentrations generally 1-200 ng/L (parts per trillion).These vanishingly small concentrations are several orders of magnitude below the concentrations where any effects have been observed or predicted for the compounds measured in this study. Acetaminophen, caffeine, carbamazepine (anti-epileptic), cotinine (human metabolite of nicotine), paraxanthine (human metabolite of caffeine), and sulfamethoxazole (antibiotic) were found most often in both studies. However compounds were more frequently detected in the shallower wells. These occurrences, and laboratory studies, suggest that of these compounds, caffeine, carbamazepine, paraxanthine, and sulfamethoxazole are more persistent in groundwater and have the most potential for transport in the subsurface.

A Happy Medium? Antidepressants in Aquatic Systems
Wastewater treatment plants do a remarkable job at removing the bulk of chemicals from the waste stream. But recent USGS studies have shown that a wide range of pharmaceuticals and other human-caused waste compounds remain despite wastewater treatment and are discharged to receiving waters across North America. Antidepressants are a commonly used class of pharmaceuticals whose pharmacological effects may extend beyond humans to aquatic organisms present in surface water systems that receive treated wastewater discharge. Yet few methods exist to detect antidepressants in the environment, and their effects on aquatic organisms are only beginning to be understood. Recently, USGS researchers developed a method to study the distribution and fate of antidepressants and their breakdown products in aquatic environments, including municipal wastewater and surface water. Venlafaxine (Effexor) was the predominant antidepressant researchers found in wastewater and river-water samples from Colorado, Iowa, and Minnesota, though other antidepressants were found as well. Typical concentrations of individual antidepressants ranged from a few nanograms per liter to thousands of nanograms per liter (for Venalfaxine) in wastewater. This indicates that wastewater is a point source of antidepressants into the environment, at concentrations that may impact aquatic life. For more information, please contact Edward T. Furlong, USGS, at efurlong@usgs.gov or 303-236-3941; or Melissa Schultz, College of Wooster, Wooster, OH at mschultz@wooster.edu or 330-263-2645.
Pa. townships soon to require septic plumbing
Every township in Franklin County soon will require residents to pump their septic tanks on a three-year schedule, according to the Pennsylvania Department of Environmental Protection (DEP).
“Every municipality will have the requirement at some point,” said Sandy Roderick, spokeswoman for the state DEP.
The requirement is part of a state initiative designed to improve local sewage management and protect groundwater.
In 1997, the state amended Act 537 to require regular maintenance of septic systems, Roderick said. The legislation mandates that municipalities require all on-lot septic systems to be pumped every three years.
“Act 537 is the municipality’s responsibility, but some have yet to show progress,” Roderick said.
“We have areas in Pennsylvania that are rural, and only have on-lot systems,” Roderick said. “Some are old, malfunctioning and contaminating drinking water.”
Local septic tank specialists S R Daley Sons of Greencastle, Pa., say that once a system malfunctions, the only remedy is expensive alternative systems.
“When a system goes bad, it is because it is not maintained,” said April Daley of S R Daley Sons. “It costs $139 to pump a tank; a replacement can cost up to $20,000.”

LC&N TELLS DEP IT NO LONGER INTENDS TO USE DREDGE IN RECLAMATION OF SPRINGDALE PIT
Request Has No Affect on Statewide General Permit Allowing Beneficial Use of Dredged Materials in Mine Reclamation
HARRISBURG — Coaldale Energy LLC, which assumed responsibilities for Lehigh Coal & Navigation Co. in April, has informed the Department of Environmental Protection that it no longer intends to pursue the use of dredged materials in the reclamation of the Springdale Pit in Tamaqua, Schuylkill County.
In a letter submitted to the department Tuesday, the company stated it is not seeking reauthorization in its pending permit renewal of special conditions that allow the beneficial use of a mixture of dredged sediment, coal ash, cement kiln dust and lime kiln dust.
The company’s decision to forgo the use of dredge has no implication for the general permit that the department issued in March 2004 in association with the use of a mixture of dredge and other materials for mine reclamation in Pennsylvania.
DEP approved amendments to LC&N’s surface mining permit in January 2005 to allow the beneficial use of dredged sediment and other materials in the reclamation project. No dredge material has been placed on site to date.

Lakehurst Acres residents’ tests indicate lead in blood

Lakehurst Acres residents’ tests indicate lead in blood

MANCHESTER — A majority of the residents at Lakehurst Acres who were tested for lead over the past two weeks showed low traces of the metal in their blood, according to state toxicology tests.
The tests were taken after abnormally high levels of lead were found earlier this month in the drinking water of the 25-unit housing complex on Pond Road. Officials have since determined the development’s water pipes corroded, releasing the lead into the water.
About 30 of the estimated 40 residents currently living at Lakehurst Acres have been tested, said Andrew Smith, state toxicologist for the Maine Center for Disease Control and Prevention.
Ideal lead levels in adults should be below 25 micrograms per deciliter, and below 10 micrograms in children, Smith said. Most of the tests taken at Lakehurst were below these limits, he said, with many falling under 5 micrograms per deciliter.
“They clearly indicate exposure,” he said of the test results. “But these are not the levels where there’s going to be any clinical intervention.”
For some of the residents at Lakehurst, the lead tests are the latest in a series of issues with the drinking water there.
“It irritates me,” said Seamus Pike. “But more than that, it’s really been stressful.”
Three weeks ago, Pike brought home his newborn son, Axel. That same day, he got a notice from C&C Realty Management of Augusta, which manages Lakehurst, saying that lead was discovered in the drinking water, and that residents should be tested.
“We’re getting him re-tested every week,” Seamus said of his son.
Axel has had a steady blood-lead level of 9 micrograms per deciliter. Seamus’ results originally reached 24, but last week decreased to 22.
“Pretty much every day I’m at the doctor,” he said. “They’re questioning me, whether I’m still taking in the water.”
Late last month, residents of Lakehurst Acres were told by C&C Realty that they should see a doctor after water tests indicated that lead levels were more than 100 times higher than federal limits.
The increased levels were detected after the property managers installed a filtration system to help eliminate arsenic — which flows naturally in the ground water of that area of Pond Road. Lakehurst’s drinking water comes from a well.
After the installation of the arsenic control equipment, the water grew more acidic and began to eat away at the water pipes and leach lead.
“Pretty much every month we had a reason why we couldn’t touch our water,” Seamus said. “We’re trying to find a way to get out of here.”
Catherine Whitney, chief operating officer for C&C Realty Management, previously has said that copper was present in the water when the company took over management of the property in January. Whitney could not be reached Tuesday for comment.
Equipment was installed last Friday to help neutralize acid levels in the water, and help stop the corrosion of pipes.
“So far, those have been looking very promising,” said Carlton Gardner, compliance and enforcement team leader for the Maine Drinking Water Program with the Department of Health and Human Services.
A new lead sample of the housing community’s water will be taken this week, he said. Results should be available by Friday.
According to the U.S. Environmental Protection Agency, exposure to lead through drinking water is relatively uncommon. The greatest exposure to lead comes from swallowing or breathing in lead paint chips and dust.
Lead is rarely found in source water — springs, lakes and rivers — but enters tap water through the corrosion of plumbing materials.
By the 1920s, most pipes installed for water distribution were made of iron, at least in part because lead was known to seriously contaminate drinking-water supplies.
But lead solder was used well into the 1980s to seal water pipes. The Lakehurst Acres property was built sometime near 1980.
In babies and children, excessive exposure to lead can result in delays in physical and mental development, according to the EPA, along with slight deficits in attention span and learning abilities. In adults, it can cause increases in blood pressure.
According to State Toxicologist Smith, lead in blood has a half-life of one month, so it could take a few months for residents at Lakehurst to process the lead out of their bodies.
“We want all of them to be as low as possible,” Smith said.
C&C Realty, an Augusta-based firm that manages 19 properties throughout the state, including Lakehurst Acres, said it will continue to provide residents with bottled water until lead levels return to normal.

The Agency for Toxic Substances and Disease Registry (ATSDR) has released the following Public Health Statement for Lead: http://www.atsdr.cdc.gov/toxprofiles/phs13.html#bookmark04
This is an excerpt:
Children are more sensitive to the health effects of lead than adults. NO SAFE BLOOD LEAD LEVEL IN CHILDREN HAS BEEN DETERMINED. …
Fetuses exposed to lead in the womb, because their mothers had a lot of lead in their bodies, may be born prematurely and have lower weights at birth. Exposure in the womb, in infancy, or in early childhood also may slow mental development and cause lower intelligence later in childhood. There is evidence that these effects may persist beyond childhood.

ADHD Cases Linked to Lead, Smoking
About one-third of attention deficit cases among U.S. children may be linked with tobacco smoke before birth or to lead exposure afterward, according to provocative new research.
Even levels of lead the government considers acceptable appeared to increase a child’s risk of having attention deficit hyperactivity disorder, the study found.
The study bolsters suspicions that low-level lead exposure previously linked to behavior problems “is in fact associated with ADHD,” …
Based on study estimates, more than 5 million 4-to-15-year-olds nationwide have levels higher than 2 micrograms per deciliter, Lanphear said.
Children with blood lead levels of more than 2 micrograms per deciliter were four times more likely to have ADHD than children with levels below 0.8 microgram per deciliter. The government’s “acceptable” blood lead level is 10 micrograms per deciliter, and an estimated 310,000 U.S. children ages 1 to 5 have levels exceeding that.

Traces of lead found in newborn’s blood

Lenora Cotta says her 15-day-old son Axel has tested positive for lead in his blood from contaminated drinking water at the Lakehurst Acres apartments in Manchester.
MANCHESTER — Axel had only been out of his mother’s womb for six days when he got tested for lead.
“It’s not exactly something you take lightly,” said his mother, 20-year-old Lenora Cotta.
She had been waiting since the Monday before Labor Day. Axel’s father, Seamus, slept little, and each phone ring at their Lakehurst Acres apartment was full of anxiety.
Cotta finally heard back Wednesday.
Axel tested positive for traces of lead, Cotta said, but the levels may be low enough to escape major health problems.
“Just the fact that it’s even a problem is ridiculous,” she said. “There are so many kids here.”
Officials say abnormally high levels of lead that have been leaking into the drinking water at Lakehurst Acres should be eliminated next week after the property owners install state-approved equipment to correct the problem.
Catherine Whitney, chief operating officer for C&C Realty Management, which oversees the 25-unit housing development on Pond Road, said the equipment will be installed by Monday and will prevent more lead from contaminating the drinking water, and poisoning the estimated 40 people who live there.
Officials believe the development’s water pipes corroded, releasing the lead into the water.
After the equipment is installed, reduction in the amount of lead in the water “will be almost immediate,” said Carlton Gardner, compliance and enforcement team leader for the Maine Drinking Water Program with the Department of Health and Human Services.
But, Gardner cautioned, it is hard to say how long it will take for the pipes to be coated and protected.
C&C Realty, an Augusta-based firm that manages 19 properties throughout the state, said it will continue to provide residents with bottled water until lead levels return to normal.
Late last month, residents of Lakehurst Acres were told by C&C Realty officials that they should consider seeing a doctor after water tests indicated that lead levels were more than 100 times higher than federal limits.
This week, nurses and volunteers from the Maine Childhood Lead Poisoning Prevention Program were taking blood samples from residents who cannot make it to a doctor.
“We wanted to make sure there were no barriers on people getting their blood tested,” said Andrew Smith, state toxicologist for the Maine Center for Disease Control and Prevention.
Test results should be available in a few days.
The Maine Department of Health and Human Services intends to pay medical fees for residents who do not have access to medical insurance.
Federal limits say lead levels in drinking water should not exceed 15 parts per billion. Water from homes tested in Lakehurst reached into the hundreds and thousands of parts per billion, with one of the highest readings hitting 1,600 parts per billion.
“Often, the problem with lead … is that it’s present with the plumbing,” Smith said.
For Lakehurst Acres, the cause of the increased lead levels came after the property managers installed a filtration system to help eliminate arsenic, Gardner said. Arsenic flows naturally in the ground water of that area of Pond Road, she said, and Lakehurst’s drinking water comes from a well.
After the installation of the arsenic control equipment, the water grew more acidic and began to corrode and eat away at the water pipes.
“Nobody expected to see this increase in lead,” Gardner said.
“An important consideration is the age of the building,” Smith said.
By the 1920s, most pipes installed for water distribution were made of iron, at least in part because lead was known to seriously contaminate drinking-water supplies. But lead solder was used well into the 1980s to seal water pipes together. Whitney said the Lakehurst Acres property was built sometime near 1980.
Lead poisoning can effect anyone, but the highest risk is to children under the age of 5, whose developing brains can be ravaged by the toxin. Even in low doses, lead can impair neurological function, and at higher levels it can cause stunted growth.
Lead could have been leaching into drinking water since May, but the effects of the lead will differ depending on how much each resident ingested, and how quickly their bodies absorbed the metals.
“We consumed a lot of it,” said Cotta.
Although the same variables play out in how long lead remains in the blood, Amrich said, in most cases lead is excreted entirely from the body within two months.
“There really is not any treatment,” she said.
The Department of Health and Human Services last week approved installing equipment that will help balance the water chemistry, and stop lead from leaching into drinking water.
“Finding lead in water in Maine is unusual,” said Amrich, whose program monitors and analyzes the roughly 16,000 blood lead test results submitted each year.
According to the Maine Department of Environmental Protection, lead is potentially present in the environment of almost 80 percent of the housing in Maine. Exposure to lead is most common in buildings built before 1950 — when paint contained up to 50 percent lead — and in buildings built before 1978, before use of it in house paint was outlawed.
Before C&C Realty was hired in January by the Lakehurst Acres Association, Whitney said, past property managers knew of increased levels of copper in the drinking water.
The federal government mandates that public housing units such as Lakehurst Acres be tested either every three years, every year, or every six months, depending on the need.
Records kept by the Maine Drinking Water Program show that six-month tests — which are administered to high-risk water systems — have been going on at Lakehurst for more than a year because of copper traces in the water, Gardner said.
