Eyes on Ohio Waters: Water Quality Monitoring in the Huntington District
The world of water quality monitoring is vast and diverse, with environmental professionals working in the field in a variety of environments and applications. From watershed monitoring to source water management , a career in water quality provides opportunities worldwide. 
 
Thaddaeus Tuggle chose to pursue a career in water quality after attending Cedarville University and working closely with the environmental faculty, who instilled in him a passion for working in streams, improving water quality, and educating people about the overall importance of watershed stewardship. 
 
After graduating, Tuggle worked for the Knox Soil &; Water Conservation District in central Ohio before eventually returning to Marshall University in West Virginia.

California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. 
 
The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). 
 
Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. 
 
 The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. 
 
 This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.
