It’s Clear: Water Clarity Is Declining

Water clarity, a strong indicator of water quality, is deteriorating in Maine lakes, according to a University of Maine graduate student’s study. The decline, says Ian McCullough, may be a trend toward eutrophication — a process in which excess nitrates and phosphates, generally due to fertilizers and sewage, stimulate growth of algae, which depletes oxygen read more It’s Clear: Water Clarity Is Declining
