Current Areas of Interest in Ohio
ALGAL BLOOMS & NUTRIENTS
Ohio WRC researchers are tracking algal blooms, analyzing potential sources, and creating techniques to reduce nutrients in water bodies. Harmful Algal Blooms (HABs) are becoming increasingly prevalent in Ohio. In 2013, 47 of Ohio’s 63 beaches exceeded the national Beach Action Value safety threshold in 20% or more of their samples, triggering beach advisories and/or closures. Toledo’s microcystin bloom in August 2014, while only rated a 6 on a 10 point scale, compromised water supplies, shutting down schools and businesses. It is now believed that moderate blooms can create substantial impacts, resulting in a need for runoff control and additional research.
WATER QUALITY AND SUSTAINABLE WATER USE
Ohio WRC researchers work to ensure that drinking water supplies and wastewater technologies are safe, sustainable, reliable, and cost-effective. Plentiful drinking water and clean surface water are fundamental needs for all Ohio residents, but they come at a cost. Watertreatment membranes clog with biofilms, requiring cleaning and eventual replacement. Water quality and ecosystem responses to restoration projects are not always well documented.
WATER & ENERGY
Ohio WRC researchers identify impacts of hydraulic fracturing and shale energy on water supply, quality, and ecosystem health. Energy production depends upon a continuous supply of water. Simultaneously, water treatment and distribution require significant energy inputs. Power generation is the single largest water use category in the state of Ohio. In 2013, 76 percent of reported water withdrawals came from 40 power facilities.
