Dioxins are a group of toxic compounds that share similar and distinct chemical structures. They are mainly byproducts of industrial processes, such as waste incineration. In 1979, the EPA banned products containing Polychlorinated Bihphenyls (PCBs), which is a chemical included under the term dioxin. However, dioxins were a major issue before the US began implementing regulations. Since dioxins break down extremely slowly, toxins that were released long ago are still being released into the environment.
Today, most people are exposed to dioxins through consuming animal products that have accumulated dioxins over time. Exposure to these toxins in humans can cause cancer, type 2 diabetes, ischemic heart disease, infertility in adults, impairment of the immune system, and skin lesions. The following measures can help decrease your risk to dioxin exposure: removing skin from chicken and fish, trimming visible fat from meats, and checking local fishing advisories when catching your own seafood.

The San Jacinto Waste Pits is a Superfund site in Harris County, Texas that is packed with dioxin and other toxic chemicals. Hurricane Harvey hit Harris County in 2017 and led to large damages and erosion throughout the region, causing the San Jacinto Waste Pits site to begin leaking toxic chemicals, such as dioxins into the surrounding communities.
CHEJ has worked with the Texas Health and Environment Alliance (THEA) and the San Jacinto River Coalition in order to help bring awareness to their nearby Superfund sites and the damages that hurricanes have caused. In 2017, THEA and the San Jacinto River Coalition succeeded in bringing attention to the waste pits and the EPA announced plans that they would remove the toxic contents from the pits entirely through a $115 million site remediation by late 2021.
In addition to THEA, residents in Wausau, WI living immediately adjacent to former Wauleco window manufacturing sites who were concerned about dioxin contamination formed Citizens for a Clean Wausau. Recent testing in a park found high levels of dioxin but the state dismissed the results. However, the state had to correct itself when CHEJ’s science director wrote a letter to the group pointing out that the state’s risk assessment failed to include dioxin’s cancer risk. Given dioxin’s high potency as a carcinogen, this was a major oversight. The group continues to fight for more testing. Earlier this year, the leader of the group ran for and won a seat on the city council, giving the group a great inside/outside approach to getting what they want. CHEJ continues to provide technical and organizing support to Wausau’s residents.
