     With the current state of toxic algal blooms in the U.S., people are discussing issues of water quality more and more; leading some to delve into the history of HABs (harmful algal blooms) and other water quality issues in the United States. This article from the Journal Sentinel presents the past and present of water quality in the Great Lakes region; from the famous burnings of the Cuyahoga River (the first one dating back to 1868, with the largest occurring in 1952), to Lake Erie’s huge improvement under Congress’ 1972 Clean Water Act.

     And though it highlights the regions uneven history, it presents a present question; why haven't recently troubled lakes like Lake Erie been labeled impaired, and efforts been made to prevent the recurring harmful algal blooms which threaten wildlife and drinking water?
