Effects of Residential Environmental Screening and Perception Surveys on Superfund Environmental Health Risk...

Area of Science:

• Environmental Health
• Community-Based Participatory Research
• Risk Perception Studies

Background:

• Superfund sites present challenges in aligning community environmental health risk perceptions with official assessments.
• Divergent perceptions can hinder effective remediation and public trust.
• Butte, Montana, a long-standing Superfund site, exemplifies this challenge.

Purpose of the Study:

• To investigate how home-based environmental screening influences residents' environmental health risk perceptions.
• To assess the impact of objective screening data on subjective risk assessments.
• To identify key factors in bridging the gap between community and agency risk perceptions.

Main Methods:

• A study involving a random sample of Butte residents at a major Superfund site.
• Participants completed surveys on environmental health perceptions before and after home screening.
• Home screening involved testing soil and drinking water for lead and arsenic, complemented by local air monitoring.

Main Results:

• Home-based environmental screening significantly improved the alignment between residents' perceptions and objective environmental screening measures.
• Key factors contributing to this alignment included co-located data collection, clear communication of results, and independent research conduct.
• Empowering residents with specific contamination data fostered greater congruence with scientific findings.

Conclusions:

• Home-based environmental screening is an effective tool for enhancing community understanding of environmental health risks.
• Independent, transparent communication of objective data can bridge the perception gap between residents and regulatory agencies.
• Empowering Superfund communities with localized environmental data is crucial for effective risk communication and management.
