Our Technical Monitoring program was established to supplement the State's monitoring efforts in other locations by providing reliable baseline values for several different physical and chemical parameters. Volunteers monitor assigned sites on a monthly basis, testing for dissolved oxygen, pH, alkalinity, nitrates, phosphates, conductivity, salinity in tidal reaches, temperature, and flow. Quality control is ensured through additional procedures.
Technical Monitoring data has been collected at thirty locations within the Delaware portion of the Christina River Basin since 1995. The data from our program are being used by the Delaware Department of Natural Resources and Environmental Control (DNREC) in their efforts to develop pollution control strategies for the Christina Basin.
The program also provides valuable volunteer-collected data is incorporated into a nonpoint source pollution water quality model used by DNREC and the US Geological Survey for the Delaware-Pennsylvania Total Maximum Daily Loads (TMDLs) effort for the Upper Christina Watershed. The Delaware Nature Society has analyzed and published this data in our watershed report series (see links in right column). It's also published every two years as part of DNREC's Watershed Assessment Report (305(b)) ( 4.65 MB PDF file).
