Scientists at Laboratory for Infectious Disease and the Environment are collaborating with Polk County Conservation in central Iowa to estimate the health risk posed to recreators in the Des Moines River and tributaries.

Samples collected over two years are tested for viral, bacterial, and protozoan pathogens, and health risk is estimated using quantitative microbial risk assessment (QMRA). Health risk will also be compared to microbial source tracking markers that indicate human and animal fecal sources as well as to standard E. coli measurements.
