Evaluating the impact of proximity to reported toxic release facilities and flood events on chronic health outcomes in the city of Galena Park, Texas

Abstract

Evidence has conclusively revealed that environmental justice communities experience poor environmental conditions compared to more affluent majority communities. However, there has been little research evaluating the health impacts of immediate proximity to industrial pursuits and flood events on a population compared to others living within the same community who are only marginally removed from these locations. This cross-sectional study (N = 130) utilized three approaches to assess health outcomes (1) the 12 item Short Form Health Survey, which creates a general physical component score, (2) self-reported noncancerous chronic conditions, and (3) self-reported diagnosis of twelve different cancers. Three risk levels were spatially created using a 5-scale ordinal score for each residential parcel based on the corresponding flood probability level and proximity to facilities which report to the United States Environmental Protection Agencies Toxic Release Inventory. Analysis revealed that general physical health scores were significantly lower (P-value < 0.001) in the medium and high-risk locations, Similarly chronic conditions witnessed a non-significant twofold increased risk in the highest-risk locations compared to the lowest (POR 1.91; 95 % CI 0.82–4.39) and a non-significant increased risk of cancer diagnosis (POR 1.51; 95 % CI 0.38–5.99). This research underscores the importance of place and health outcomes even within relatively geographically compact communities. Public health and urban planning interventions and designs should take into account fine grain approaches to respond to community needs while still being mindful of limited resources.
