Sassafras River report card indicates high turbidity, nutrient problems
The Sassafras River Association has been working with people in the Delmarva Peninsula to improve water quality of the Chesapeake Bay tributary, but water quality improvements are still needed, according to the association’s annual report card on river conditions. 
 Nitrogen and phosphorus pollution is a continuing problem in the river due to agricultural operations nearby. There is also high turbidity because of runoff from a number of sources. 
 A series of wetlands maintained by the association and other organizations should improve river conditions in the long run. 
 The Sassafras River’s upper estuary was graded as a ‘C’, the lower estuary as a ‘B’ and the creeks feeding the river were graded as a ‘D.’ 
The river still is considered an impaired waterway by the U.

Continuous data collection in Lancaster County, Pennsylvania, started about 5 years ago, and the county will be making a major upgrade over the next year—switching from relying solely on the internal storage of water quality sondes to telemetry units that enable real-time data viewing.

 Telling Lancaster County's Story Through Data 
Since the Lancaster County Conservation District started monitoring county waterways, the goal has remained the same, according to Amanda Goldsmith, Watershed Specialist for the Watershed Department.

In the early 2000s, along the coast of northern California, where the redwoods dominate the forests, and the Pacific Ocean shapes shorelines, a Humboldt University undergraduate student took the first steps into a lifelong love of marine biology. 
 
Dean Janiak accepted an invitation to help a graduate student with fieldwork in rocky coastal tide pools, and so began a journey that led him from California to Connecticut to Florida and eventually to the world, where he has facilitated research in communities across the globe. 
 
While finishing up his masters of Oceanography from the University of Connecticut, Janiak continued researching fouling communities–marine life that live on hard, often artificial surfaces such as docks–at the Smithsonian Environmental Research Center.
