WashU project to analyze environmental health of St. Louis neighborhoods impacted by tornado

A newly launched Washington University project will examine the environmental health of neighborhoods devastated after an EF3 tornado swept through the St. Louis area in May.

Contamination Level Evaluation and Analysis for Neighborhoods — or CLEAN STL— will test and analyze the soil and air quality in those communities for major contaminants. It’s the first project under the university’s WashU Public Exchange initiative. The goal is to partner university experts with residents, local organizations and industry partners to address social problems.
