Delaware Agricultural Shallow Groundwater Monitoring Network

Studies in the Delmarva Peninsula have demonstrated that groundwater in shallow unconfined aquifers near agricultural lands is susceptible to contamination from chemicals applied at the land surface.

Observed concentrations of nitrate in shallow groundwater commonly exceed the U.S. Environmental Protection Agency Maximum Contaminant Level of 10 mg/L on the peninsula. Groundwater...

Monitoring Water-Quality Response of Conservation Practices in the Bucks Branch Watershed, Sussex County, Delaware

The Bucks Branch sub watershed in the Nanticoke River basin has been identified as having one of the highest concentrations of nitrate in surface water of all sites sampled in Delaware. 

Changes in water quality related to changes in agricultural conservation practices will be seen first in shallow groundwater as groundwater is the major source of nitrate in surface water.

Understanding and mitigating bee drownings in open feeders

Whereas open feeders are relatively inexpensive and are easily set up and maintained, they do present a drowning hazard to bees. We observed that bees feeding off the walls of the open container fell into the sugar water because of their incarnation, interactions with other bees and when shooed off the feeder walls while removing the feeder for...
