Protect Gainesville’s Citizens Indoor Dioxin Study is Just Plain WRONG

6 Oct

Part Four: Toys in the Attic

Attic-Air-Pollution

In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. This would be exponentially compounded if there were exposure pathways of contaminants from a Superfund site. Other research indicates that people spend approximately 90% of their time indoors. Thus, for many people, the risks to health from exposure to indoor air pollution may be greater than risks from outdoor pollution.

Elderly manAdditionally, people exposed to indoor air pollutants for the longest periods are often those most susceptible to their effects. Such groups include the young, the elderly, and the chronically ill, especially those suffering from respiratory or cardiovascular disease.

According to the “workgroup”, there was no data on indoor contamination prior to their 2012 round of indoor testing. “The past health risk from exposures to chlorinated dioxins/furans in the dust of 17 homes near the Koppers facility prior to 2012 is unknown. There was no testing of indoor dust specifically for chlorinated dioxins/furans prior to 2012.”  

AtticAccess2However, there is a massive amount of research on testing attic dust samples for historical loading of contaminants. That means you can utilize attic samples to determine contamination from the past. US EPA has studied the risk of exposure to chemicals in the home resulting from renovation and remodeling activities and has also concluded that an exposure pathway is complete when occupants access the attic space. Houses are designed to breathe. An attic is like a time capsule of a neighborhood’s environment.

The ridiculous reason given for not sampling attics was that the “workgroup” felt attics were either non-existent or too small for residents’ use. There is absolutely no evidence supporting this, quite the contrary. Who doesn’t utilize storage space? And even if people don’t access their attics very often, when they do, they could be exposed to higher concentrations of contamination. Residents asked about getting their attics tested but were denied even though it would have filled the gaping hole of unknown past health risk from exposures to chlorinated dioxins/furans in the dust of  homes near the Koppers facility prior to 2012. The lame excuse and uncompassionate remedy  the “workgroup”  offered in the Indoor Contamination Study stated ”Because the attics of houses near the Koppers facility are typically small and the amount of time people spend in their attics is limited, the indoor dust workgroup did not recommend EPA test attic dust. Homeowners, however, can always choose to test attic dust at their own expense.”

AtticAccessRoomOnce again, the burden of proof and the prohibitive expenditure is on the homeowner. Will there be deed restrictions to access attics or to do home renovations in the Stephen Foster neighborhood? The “workgroup” even goes so far as to state, “This report does not, however, address whether the Koppers facility is the only or major source of dioxins in the dust of nearby houses.”

So, what does the report address? Seems like the only thing the “workgroup” took plenty of time to do in the report was to try to invalidate the independent indoor tests residents had done that fingerprinted dioxin contamination to the Koppers facility. Beazer East has already said they are not coming back if more contamination is found in the neighborhood, and the City of Gainesville has released them from any legal responsibility, so who do sick and dying residents have to turn to for help? Legal recourse is the only avenue left, but unless you’re made of money and can ride out the “stonewall” the responsible party has used successfully for the past thirty years, you’re out of luck.

Thanks “Protection Agencies” for analyzing sample data provided by the responsible party to determine how much they would have to clean up the surrounding neighborhoods. Your conclusions really helped…..the responsible party.

Pretend Gainesville Cares’ Indoor Dioxin Study Is Just Plain WRONG

15 Sep

Part Three: Workgroup’s Indoor Dioxin Study Ignored Two of the Three Exposure Pathways for Contaminants

Attic-indoor-air-pollution-family

Only one pathway of exposure was studied in the workgroup’s investigation of indoor contamination in the Stephen Foster neighborhood. The tracking in of contaminated outdoor soil which might result in the incidental swallowing of very small amounts of indoor dust. Samples for this pathway were obtained by vacuuming dust from floors. There are two other equally relevant pathways of exposure that also meet all five criteria according to the EPA’s pathway of exposure definition that the workgroup failed to study.

hazmat babyTheir study “does not address inhalation of indoor dust. Because of the large day to day variation in indoor air quality, the 2011 dioxin dust workgroup (made up of county/state/federal health & environmental agencies, University of Florida toxicologists, ‘community leaders’, and THE RESPONSIBLE PARTY) did not recommend indoor air testing.” Why would a valid toxic exposure pathway not be studied?

 

“Also, extrapolation of indoor air dioxin levels based on levels in carpets and on floors is too uncertain to accurately assess the health risk from dust inhalation.” Why would an indoor AIR test be sampled from carpets or floors? The devil is in the details and makes it much easier to understand this strange choice of a sample area for indoor AIR testing. Because floor dust is tracked in from outside by foot traffic and is the only pathway affected by the outside soil removal undertaken by the responsible party as a clean-up solution. Beazer East, Inc. funded and supplied the EPA with indoor test results of the one and only pathway with a direct tie to the outside soil remediation they were performing.

Attic-air-quality-test-services

hazmat dog“This report also does not address skin contact with dioxins in indoor dust. Health scientists know too little about the toxicity of dioxins from skin contact to assess the health risk.” But, the workgroup had no problem foraying into uncharted waters when they devoted the bulk of their indoor dioxin study to the brominated dioxins found in homes, even though “health scientists know too little about the toxicity of the brominated dioxins/furans to assess their health risk” and they do not even originate from the Superfund site.

The excuses for not using two ironclad contamination exposure pathways make no sense unless the only pathway of exposure the workgroup wants to consider is the one Beazer East “theoretically” diminished by the replacement of outside soil to the State standard of 7ppt.

The same entities that set the INDOOR dioxin contamination cleanup standard to the unusually high 190 ppt behind closed doors, also decided not to pursue these genuine health risk pathways. So why only use the floor dust as a pathway of exposure, when “Remedial Action Plans (RAPs) should not be approved without a demonstration that ALL relevant pathways have been addressed”? It would be economically catastrophic to Koppers Industries’ wallet if a precedent of permanent relocation, or even an area-wide indoor home remediation was initiated here in Gainesville Florida, and would set the dominoes falling throughout their entire empire of Superfund sites (and they have many, all around the world). This is where people’s lives get trumped by something called “cost prohibitness”. Where there’s smoke, there’s fire. And when the company in charge of the clean-up is also in charge of determining how much they have to clean, the residents with contaminated homes are being manipulated and marginalized in a real game of life or death. If there was enough contamination outside for a foot of soil to be removed across the entire neighborhood, why are some residents being condemned to live in homes with much higher levels of contamination on the inside?

WELLS FARGO REPACKAGES DIOXIN CONTAMINATED HOMES FOR RESALE TO LOW INCOME FAMILIES

4 Aug

Before_After

Wells-Fargo and other banks are profiting by foreclosing and reselling Cabot-Koppers Superfund site contaminated properties, in Gainesville Florida. Wells-Fargo covers up all evidence of contamination before the resale and does not disclose to the new buyer despite Florida law requiring them to do so.

According to their mission statement, “Wells Fargo’s ongoing respect for human rights reflects our vision and values. This effort is done with the understanding that in some circumstances we may go above and beyond what the law and industry standards require. We are dedicated to corporate social responsibility and strive to uphold human rights in all our business activities.”

Ignoring this mission statement and families‘ pleas for assistance out of Gainesville Koppers Arsenic-Dioxin-PAH contaminated homes, Wells-Fargo forecloses on the dangerous properties,  continuing their pattern of discriminatory mortgage lending practices. This happens even when attorneys for the residents provide test results of the contamination inside their houses. With the toxic cocktail that tests have fingerprinted to the Koppers Superfund site, some of these homes are more contaminated than a meth house.

The Stephen Foster Neighborhood in Gainesville Florida is subject to an ongoing cycle of exodus and repopulation. When a generation of residents experiences the health effects of toxic exposure and learns about the superfund contamination that banks and realtors failed to disclose to them. Population and property values plummet as homeowners abandon toxic homes to protect their families. Lured by cheap home sales, low income families and rental investors repopulate the neighborhood after banks foreclose and resell the dangerous homes without disclosing the Koppers Superfund Site or the indoor contamination of the surrounding communities.

Because residents are gathering at onsite auctions to protest the resale of highly contaminated homes, banks like Wells-Fargo are resorting to the new tactic of online auctions and live auctions in cities far from where properties are actually located, to shut out the public outcry. Case in point, a before and after of the above property which is one of the most highly contaminated residences in the neighborhood, auctioned off by Wells Fargo with no disclosure as required by Florida law.

The Gainesville City Attorney’s recommendation to homebuyers who have unwittingly purchased a Koppers contaminated home without disclosure is to take legal action and file suit as soon as possible to protect your family.

The Stigma Is Here To Stay…And It Won’t Whitewash Away

28 Oct

Research studies confirm that superfund neighborhoods retain their stigma even decades after EPA says they are clean and safe.

Stephen Foster Neighborhood is subject to an ongoing cycle of exodus and repopulation. When a generation of residents experiences the health effects of toxic exposure and learns about the superfund contamination that banks and realtors failed to disclose to them, population and property values plummet as homeowners abandon toxic homes to protect their families. The neighborhood repopulates as banks and realtors foreclose and sell the dangerous homes again without properly disclosing the Koppers Superfund Site and offsite contamination. More than 70% of Stephen Foster homes have been abandoned at least once.

When affected homeowners turn to the government for help, their elected officials’ response is to tell them they should sue. Residents who cannot afford to leave their hazardous homes are angered by the government’s failure to protect their families. Their anger, sense of hopelessness, and fear for their families’ future are well-founded. A partial list of resident-reported maladies related to toxic exposure including some diseases the Veteran Administration relates to Dioxin/Agent Orange includes:

Asthma Onset                                                        Neurological Impairment
Chloracne                                                               High Suicide Rate
Chronic B-cell Leukemias                                   Non-Hodgkin’s Lymphoma
Chronic headaches and nose bleeds                 Parkinson’s Disease
Chronic rashes and phantom itches                 Peripheral Neuropathy
Compromised Immune System                         Prostate Cancer
Diabetes Mellitus Type 2                                     Respiratory Cancers
Hodgkin’s Disease                                                 Soft Tissue Sarcomas
Ischemic Heart Disease                                       Spina Bifida, other Birth Defects
Liver Dysfunction                                                 Thyroid Cancer
Lupus                                                                       Unexplained Seizures

Wells Fargo and Fannie Mae Hate You and Your Children

WellsFargoLogoAccording to their mission statement, “Wells Fargo’s ongoing respect for human rights reflects our vision and values. This effort is done with the understanding that in some circumstances we may go above and beyond what the law and industry standards require. We are dedicated to corporate social responsibility and strive to uphold human rights in all our business activities.” Seriously? Actions speak louder than words.

Wells-Fargo and HUD profit by using Fannie Mae to put new families into hazardous homes.
Ignoring families’ pleas for assistance out of Koppers Arsenic-Dioxin-PAH contaminated homes knowingly financed by Wells Fargo, Wells Fargo forecloses on the dangerous properties. Wells Fargo then transfers ownership to HUD for the full value, enabling HUD to sell the toxic homes to new families through Fannie Mae.

More Proof that Wells Fargo hates you and your children

Wells Fargo and FannieMae are preparing to sell the most hazardous property in the Koppers Superfund neighborhood. The unscrupulous actions of these entities will assure that a new and unsuspecting family will move into this highly toxic home, by nondisclosure or through an uncaring property investor who will rent it out with a fresh coat of paint.

Either way, a new round of innocent victims will be exposed to high levels of dioxins and the lethal combination of:

Is Gainesville the Next Love Canal?

13 Aug

Beazer East says they have finished their “cleanup” of Stephen Foster Neighborhood, but a newly updated Center for Public Integrity report shows that Gainesville’s Koppers Superfund Site is still one of the 114 most dangerous Superfund Sites in the nation. Despite EPA claims, human exposure and contaminated groundwater migration continue in communities surrounding Koppers, as they do in communities like Escambia FL, Libby MT, Love Canal NY, and other Superfund neighborhoods that received similar topsoil replacement- these “cleanups” do not work and are not protective of residents’ health in the short or the long-term.

KOPGVL114 Most Dangerous Superfund Sites

Beazer East hired Sevenson Environmental Services to handle the contaminated soil removal in Stephen Foster Neighborhood in Gainesville. Love Canal families who moved in after the EPA told them it was safe and clean are now suing Sevenson, the city of Niagara Falls, the Niagara Falls Water Board, and Occidental Chemical Corp for negligence in the original cleanup more than 30 years ago.

 Koppers water migration

Among the deluge of resident complaints are reports of Sevenson workers leaving contaminated topsoil around trees and house foundations in Stephen Foster Neighborhood, creating massive islands of toxic soil in the new topsoil. The pooled water in the photo above is one example of contaminated groundwater that migrated directly from Koppers Superfund Site into the newly dug, “clean” area.

National Institute of Health (NIH): Dioxin exposure causes transgenerational health effects

27 Sep

In a WSU press release, Skinner said of his latest findings, “It is not just the individuals exposed, but potentially the great-grandchildren that may experience increased adult-onset disease susceptibility.”

By Brant Hamel

A new study, funded in part by NIEHS, found that dioxin affects not only the health of an exposed rat, but also unexposed descendants through a mechanism of epigenetic transgenerational inheritance.

The study was conducted in the laboratory of Michael Skinner, Ph.D., a professor in the Center for Reproductive Biology in the Department of Biological Sciences at Washington State University (WSU) who designed the study. Co-authors included assistant research professor Mohan Manikkam, Ph.D., research technician Rebecca Tracey, and postdoctoral researcher Carlos Guerrero-Bosagna, Ph.D.

“Although not designed for risk assessment, these results have implications for the human populations that are exposed to dioxin and are experiencing declines in fertility and increases in adult onset disease, with a potential to transmit them to later generations,” the authors concluded.

Dangers of dioxin last for decades after initial exposure

Dioxin, 2,3,7,8-tetrachlorodibenzo[p]dioxin (TCDD), is a chemical compound that constitutes part of the Agent Orange herbicide used as a defoliant in the Vietnam War. According to research cited in the study, exposure is estimated to have caused 400,000 deaths and 500,000 birth defects. Dioxin has also been released from industrial accidents, leading to human exposures. Due to its extremely long half-life of up to 10 years in humans, dioxin may still affect pregnancies occurring even 20 years after exposure.

In the Skinner group’s experiments, exposure to dioxin caused changes in the DNA methylation patterns of sperm that were transmitted across generations, in an imprinted-like manner, to affect the health of multiple generations of descendents. The grandchildren of exposed rats showed dioxin-induced effects ranging from polycystic ovarian disease to kidney disease. The work raises the serious concern that even if toxic chemicals, such as dioxin, were completely removed from the environment, they could continue to cause disease for multiple generations.

Health effects of dioxin include early onset of puberty in females

Skinner’s group used low in vivo doses of dioxin, so that toxic effects were not expected. Female rats were exposed while pregnant, and both their direct progeny and descendants two generations removed were examined.

Although the most prominent phenotypes were kidney disease in males and polycystic ovarian disease in females, a number of other effects including abscesses, colon impaction, lung abnormalities, and missing testes were also observed in animals from the dioxin-treated lineage. Additionally, females from the dioxin-exposed lineage experienced the early onset of puberty. Conversely, males showed delayed puberty, suggesting sex-specific effects of exposure. Early puberty in humans has increased over recent decades and is believed to have an environmental link.

Dioxin alters methylation patterns in germ line DNA across generations

The researchers were able to identify 50 specific regions of DNA that were differentially methylated in the dioxin-treated animals. These regions were permanently reprogrammed and protected from DNA methylation, in a manner that allowed them to be passed down across generations. In the future, these regions may serve as biomarkers that would allow early detection of exposure and risk for disease.

Other chemical compounds, including bisphenol A, phthalates, the insecticide DEET, and the jet fuel JP8 have all been shown to promote disease across generations, through a similar mechanism of epigenetic transgenerational inheritance (see story). This pathway of disease propagation exists not only in rats, but also in humans, mice, worms, flies, and even plants. Thus, future research will be needed to see if other environmental compounds may also lead to health effects across generations.

In addition to NIEHS, NIH and the U.S. Department of Defense provided support for the study.
