EPA Soil Testing Reveals Elevated Cancer-Causing Chemicals in Houston’s Fifth Ward: What Residents Need to Know
“EPA soil tests in Houston’s Fifth Ward found elevated levels of cancer-causing chemicals in 42% of sampled properties.”
In a recent development that has sent shockwaves through Houston’s Fifth Ward community, the Environmental Protection Agency (EPA) has unveiled concerning results from their soil testing efforts. These findings have brought to light a pressing environmental issue that demands our immediate attention and action. As we delve into this critical matter, we’ll explore the implications of these test results, their potential impact on resident health, and the steps being taken to address this alarming situation.
Understanding the EPA Soil Testing Results
The EPA’s investigation in Houston’s Fifth Ward focused on historical industrial site cleanup, particularly a former wood treatment plant linked to cancer-causing substances. The soil samples taken from 27 consenting property owners north of Liberty Road revealed a troubling pattern: six properties showed elevated levels of either dioxine or benzo(a)pyrene, with two properties exhibiting elevated levels of both chemicals.
While the EPA has stated that there are no immediate health risks requiring urgent action, these findings highlight the long-term environmental health concerns that have plagued this community for decades. The presence of these elevated cancer-causing chemicals in residential areas underscores the lasting impact of industrial pollution on urban communities.
The Source of Contamination: A Historical Perspective
At the heart of this environmental issue lies a wood treatment plant that began operations in the area over a century ago. Initially run by Southern Pacific and later by Union Pacific, this facility used creosote, a tar-like substance, to treat wood poles and railroad ties. Creosote has long been linked to cancer and other health issues, making its presence in residential soil a significant concern.
The historical use of creosote at this industrial site has left a lasting legacy of contamination, one that continues to affect the Fifth Ward community today. This situation serves as a stark reminder of the long-term consequences of industrial practices on urban environments and the importance of rigorous environmental protection measures.
Breaking Down the Chemicals of Concern
The EPA’s soil testing focused on two primary chemicals of concern: dioxine and benzo(a)pyrene. Both of these substances are known carcinogens, meaning they have the potential to cause cancer in humans. Let’s take a closer look at each:
- Dioxine: A group of toxic chemical compounds that are byproducts of various industrial processes. Long-term exposure to dioxins can lead to reproductive and developmental problems, damage to the immune system, and cancer.
- Benzo(a)pyrene: A polycyclic aromatic hydrocarbon (PAH) formed during the incomplete burning of organic matter. It’s commonly found in coal tar, creosote, and other industrial byproducts. Benzo(a)pyrene is a known carcinogen and can also cause reproductive issues.
The presence of these chemicals in residential soil poses potential long-term health risks to the community, particularly if exposure occurs over extended periods.
Community Response and Concerns
The EPA’s presentation of these findings at a community meeting drew frustration from longtime residents of the Fifth Ward. Many expressed dissatisfaction with the ongoing environmental health concerns and the perceived lack of action over the years.
Joe Ballard, whose family home stands directly behind the former plant site, voiced his skepticism about the need for further testing. He and his siblings grew up playing in what they describe as creosote tar pits and drinking from backyard wells, highlighting the direct exposure many residents have had to these contaminants over the years.
“It’s been going on since 1904,” said one frustrated neighbor, while Ballard added, “The damage is already done.”
This response underscores the deep-seated concerns within the community and the urgency of addressing not just the environmental contamination, but also the trust deficit between residents and regulatory agencies.
EPA Recommendations and Precautions
Despite the elevated levels of chemicals found in some properties, the EPA has stated that there is no immediate health risk that would necessitate urgent action. However, they have recommended basic precautions for residents, especially those with elevated chemical levels in their yards.
Casey Luckett Snyder, EPA Project Manager, advised: “If you have a one year old playing outside eating dirt, that’s not a good idea. You want to go to the park instead.”
While this advice may seem simple, it underscores the importance of being mindful of potential exposure pathways, particularly for young children who are more susceptible to the effects of environmental contaminants.
