Community Science

The Neshaminy Watershed Association engages community members in scientific research and environmental monitoring. Our community science programs provide valuable data about watershed health while educating participants about water quality and aquatic ecosystems.

Salt Watch Initiative

Our Salt Watch program samples creeks throughout the watershed to monitor chloride levels (from road salt) and nitrate concentrations (from agricultural runoff or wastewater sources).

2023 Findings

  • Elevated chloride levels detected, especially in tributary streams
  • Nitrate levels sometimes exceeded drinking water standards
  • Data helps identify pollution hotspots and inform management strategies

Macroinvertebrate Surveys

Aquatic macroinvertebrates (small organisms visible to the naked eye) serve as excellent indicators of stream health. Different species have varying tolerances to pollution, making them valuable biological monitors.

2023 Survey Results

Over 9 months, we surveyed five sites throughout the watershed to assess stream health and build a baseline ecological dataset.

  • Limited presence of pollution-sensitive species
  • Findings suggest many stream sections may not meet environmental "attaining" standards
  • Data informs restoration priorities and conservation strategies

Transparency & Data

NWA is committed to transparency in our environmental monitoring work. We share our findings with the community, local governments, and partner organizations to inform decision-making and raise awareness about watershed health.

Our data helps identify issues like salinity, nitrate pollution, and ecological degradation, guiding both immediate actions and long-term conservation planning.
