Long-Term Nitrate Trends in PEI Streams

The Government of PEI monitors nitrate concentrations in streams to provide relevant information to the impacts from high amounts. Excess nitrate in downstream areas such as ponds or estuaries can lead to the excess growth of aquatic plants and algae such as sea lettuce. It can also lead to water quality issues such as anoxic events. The Canadian Water Quality Guideline for Aquatic Life for nitrate (3 mg/l) is exceeded in many Island streams.

Nitrate is one of the substances measured in a long-term monitoring program in 10 Island streams. Since each these streams have been sampled for many years, a long-term record of how the concentration has been changing over time (trends) is available under resources. These nitrate trends allow us to see if the issue is getting any better or worse over time.
