Congressman Bob Latta (R-OH), member of the House Committee on Energy and Commerce Environment and the Economy Subcommittee, today participated in a hearing examining the toxins in drinking water caused by harmful algal blooms. This hearing was a continuation of Congressman Latta’s efforts to address the algal blooms issues in the Great Lakes following Toledo’s August water advisory, which left 500,000 people without drinkable water.

“Our drinking water is one of our most valuable resources, and we must look at the entire picture when determining how to ensure the health of our Great Lakes and surface waters,” said Latta. “Today’s hearing to examine the effects of harmful algal blooms in our drinking water is an important step in bringing Congressional attention to this matter, and I look forward to continuing to work with all parties involved to solve this problem and protect human health.” 

At the hearing, members heard testimony from U.S. Environmental Protection Agency (EPA) Office of Ground Water and Drinking Water Director, Dr. Peter Grevatt, Ohio EPA Director, Craig Butler, John Donahue from American Water Works Association and Lynn Thorp from Clean Water Action. 

The discussion provided insight about the various sources that lead to algal bloom growth. It also shed light on the obstacles to addressing algal blooms in our drinking water, including the need to gain a better understanding of the various types of cyanobacteria and cyanotoxins, as well as safe human threshold levels. The limitations on current testing, including costs and a need for qualified technicians, was also stressed.

In addition, the U.S. EPA indicated that it is currently conducting an independent, external peer review of the draft health advisory for microcystins and Cylindrospermopsin. The health advisory is expected to be released in Spring 2015, a timeline that will ensure it reflects the best available science and data to ensure public health is protected.
