The Nanticoke River has received a grade of C+ from an environmental group.
This is down from the Nanticoke Watershed Alliance report in 2015.
WBOC reports that the downgrade is probably due to localized rain fall during the summer and fall of 2016.
In addition, samples at the Transquaking River showed high bacteria levels than in the past indicating human activity including septic tank or other sewage leakage.
Over 40 citizen scientists participated in the monitoring taking samples and measurements every other week from late March through early November.
