Description:
A Water Quality Early Warning System using On-line Toxicity Monitors (OTMs) has been deployed in the East Fork of the Little Miami River, Clermont County, OH. Living organisms have long been used to determine the toxicity of environmental samples. With advancements in electronic and computer technology, biomonitors are being developed that can assess the toxicity of water samples by measuring organism behavior or physiological responses in real time. Drinking water sources have come under increasing scrutiny in recent years, with issues ranging from ecological impacts to public health and national security. In partnership with Clermont County’s Office of Environmental Quality, a network of water quality monitors utilizing a bivalve OTM were established in the fall of 2006 to track water quality changes for both ecological and source water protection. Several runoff related events have been recorded. Practical details of the implementation and subsequent monitoring as well as data and analysis will be presented.
