Metric Contribution to Action
Monitoring in-stream nutrient levels identifies pollution hotspots and informs targeted actions to reduce nutrient runoff and wastewater impacts.

Observations, Successes and Challenges

  • Allows for trend analysis
  • Data collection is complex and resource-intensive
  • Nutrient concentrations can fluctuate based on rainfall, land use changes, and agricultural cycles, making it difficult to establish clear patterns.
  • Thresholds for "high" or "low" concentrations vary, i.e., Different ecosystems have different tolerances for nutrient levels, making standardization challenging.
