Delaware River Aquatic-Plant Biomass Study
Changes to water quality can emanate from many different sources.
  • Natural sources include geologic transformations, animal wastes, and the decomposition of detritus.
  • Anthropogenic sources include point-source discharges from wastewater treatment plants, commercial businesses, and industry; and non-point source contamination from road maintenance, agricultural practices, and residential home and yard maintenance.
  • Atmospheric deposition contains both natural and man-induces chemical constituents that may degrade water quality.

To better understand the relationships between the multiple sources of contamination and the possible range of effects from these potential alternations to the aquatic environment, the DRBC is using the water quality and flow data collected from the SRMP to calibrate watershed and open-channel computer models.
