The scope of environmental damage in the wake of this spring's massive flooding is just starting to come into focus.
The early findings: Iowa is awash in bacteria, plagued with pesticides, and doused in oil and dangerous compounds, but at concentrations that don't pose an immediate risk to aquatic life or human health.
The U.S. Environmental Protection Agency collected 169,836 stray computers, appliances, televisions and containers as of July 17, most in Linn County. Contractors are still collecting wastes for burning, burial or recycling from scores of containers holding propane, gasoline, pesticides and kerosene that were sent downstream.
Many of the containers never broke. But tons of waste — chemicals, oils and sewage — ultimately spilled into floodwaters, communities and fields, killing hogs, spoiling waterways, and closing state-park campgrounds and beaches.
The Iowa Department of Natural Resources, the University of Iowa Hygienic Laboratory and the EPA fanned out in the wake of the flooding in one of the largest sampling efforts in recent Iowa history. Crews checked upstream and downstream of 15 communities, screening for 300 compounds and amassing 20,000 readings.
