Every week we post the results of our pathogen sampling on the Lower Raritan River.

Six public access sites are sampled weekly from June to October. These sites include docks, boat ramps, fishing piers, and beach locations.

Pathogen results come out every Friday for each site and the data is shared here.

This information helps you decide if the Raritan River is safe for recreation.
