Dataset Overview

The Roe Jan Watershed Community (RJWC) began monitoring the Roeliff Jansen Kill for Enterococcus, a sewage-indicating bacteria, ​​​in May 2016. As of 2017, RJWC members sample at 16 points in the Roe Jan, its tributaries, and the nearby Hudson from October to May. Entero samples are processed at the Bard Water Lab, which also records temperature and conductivity data collected by RJWC volunteers while sampling.
