Water Quality Data

Four county departments worked together to conduct a year-long water quality monitoring program for the Bronx River in Westchester County. The Department of Planning teamed up with the Departments of Health and Laboratories and Research, with cooperation from the Department of Parks, Recreation and Conservation, to collect and analyze samples each month at eight locations along the Bronx River in Westchester County from April 2006 through April 2007.

As recommended by the Department of Health, the following parameters were determined from “grab” samples collected by the Department of Health and analyzed by the Department of Laboratories and Research at each of the eight sites along the Bronx River in Westchester:

  • total coliform
  • fecal coliform
  • E. Coli
  • enterococci
  • ammonia
  • nitrates
  • nitrites
  • phosphorus
  • total suspended solids
  • dissolved oxygen
  • pH
  • temperature
