Salem River Water Quality Monitoring
Project - Phase I
Year 2001

Fall 2001. A series of meetings were held between Rutgers Cooperative
Extension Salem County and the Center for Remote Sensing and Spatial Analysis,
Rutgers University. A research/GIS plan was initiated for year 1
of this project. Initial outreach to stakeholders was accomplished
through the development of fact sheets that described the problems facing
the Salem River watershed.
Winter 2001. All relevant GIS coverages for watershed area #17
were obtained including NJDEP watershed boundaries, hydrology, ambient
biomonitoring network data, NRCS soils data, septic/sewers data, and digital
ortho-photography of the Salem River/Delaware Estuary Watershed area.
In addition, preserved farmland coverage of Salem County was received from
the NJ state agricultural development commission and updated via personal
communication with the Salem County Planning Office. An initial
reach of the Salem River labeled as severely impaired was selected as a
starting point for water quality monitoring. 28 sites along the river were
selected for water quality testing.
For 6 weeks during the summer of 2001, nitrogen, phosphorus, pH, temperature,
and conductivity were measured at each of the 28 sampling points (shown
as black dots) below.

Initial results indicate that all sites (except for one) along the Salem
River are well below safe drinking water standards (10 ppm) for nitrogen.
Areas of high phosphorus and conductivity were detected probably due to
agricultural operations and stormwater run-off. Over the course of
the winter, we will be working with other government agencies and growers
in the region to educate them about these findings and to develop best
management practice strategies for the future.
