Objective: An innovative academic-community partnership studied daily decisions in communities of mostly Spanish-speaking, low-income residents of colonias in Hidalgo County, TX, about risk of exposure to fish contaminated by PCBs at an Environmental Protection Agency (EPA) Superfund site.
Design And Sample: The team used focus group interviews with colonia residents and content analysis to assess knowledge of risk related to the Superfund site, the Donna Reservoir and Canal System.
Results: (1) many lacked knowledge of the Superfund site contamination; (2) a few participants fished at the lake, knew people who did so, and consumed the catch, but most participants feared going there; (3) some participants remember receiving messages saying not to fish at the site, although they recalled nothing about contamination, but most participants knew of no such messages; (4) many use cell phones to get local information through personal networks and several Spanish-language news sources, but they have no consistent, culturally tailored local information source.
Conclusions: The findings indicate the need for further efforts to design culturally tailored means of communication and messages to inform local communities widely about the dangers related to the Superfund site and thus decrease health disparities resulting from consuming fish from the site.

Demographic inequities and cumulative environmental burdens within communities near superfund sites on Long Island, New York.

Nassau and Suffolk Counties of Long Island, New York are densely populated and contain 34 federally-designated and 449 state-designated Superfund sites, potentially exposing communities to toxic releases. We conducted a distributive justice analysis assessing proximity to Superfund sites, community socio-demographics, and other environmental burdens. Socio-demographic and environmental variables for 665 census tracts were obtained from the United States Census and Environmental Protection Agency's Environmental Justice Screening and Mapping Tool.

The mobility and bioavailability of metal contaminants such as lead (Pb) and zinc (Zn) is impacted by their interactions with other sediment constituents such as iron (Fe), sulfur (S), and organic matter, which depend on sediment redox conditions. Understanding the role that water level fluctuations have on redox conditions and subsequent impacts on metal mobility is critical for predicting impacts of increased wetting and drying cycles resulting from climate-related changes or management actions. This study measured the sediment-porewater partitioning of Pb and Zn in the Coeur d'Alene River basin downstream of the Bunker Hill Superfund Site under both flooded and seasonally dry conditions.

Polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs) are contaminants of concern in the New York/New Jersey Harbor and in the organisms of the Newtown Creek Superfund site, which lies within the harbor. Because PCDD/Fs are never intentionally produced, identifying their sources can be challenging. In this work, sources of PCDD/Fs to the sediment of Newtown Creek were investigated using Positive Matrix Factorization (PMF) to analyze two data sets containing data on concentrations of (1) PCDD/Fs and (2) PCDD/Fs plus polychlorinated biphenyls (PCBs).

Article Synopsis
- Most people in the US are exposed to PFAS, which can lead to health risks, especially in low-income communities near PFAS-polluting facilities.
- In a study in Southern California, researchers connected PFAS levels in plasma samples with data on water contamination, food access, and pollution sources to analyze exposure impacts.
- Results showed that higher PFAS levels in drinking water and the presence of Superfund sites increased PFAS concentrations in participants' blood, highlighting the need to address PFAS exposure in disadvantaged areas.
