Bacterial contamination has already led to the closure of at least eight beaches across Michigan, according to the Michigan Department of Environment, Great Lakes, and Energy. Although some have since reopened, more closures are expected throughout the summer.
Several pollutants can cause beach closures in Michigan and elsewhere. Sanitary and combined sewer overflows, groundwater runoff, failing septic systems, and harmful algal blooms can all contribute to beaches being unsafe for swimming.
Dr. Xiaobo Tan commented on beach contamination, its impact and what we can do about it.
“In freshwater bodies, too much phosphorus is the cause of toxin production from harmful algal blooms. These toxins disrupt the economy, coastal recreation and fishing. We need to find ways to reduce phosphorus from agricultural sources from getting into surface water bodies like Lake Erie.”
