The NJ Road Salt Impact Study is back for 2022! Click above to request your chloride test strips to start monitoring your favorite New Jersey streams and lakes. This project engages community scientists to assess the impacts of winter road salting on New Jersey freshwater nontidal water bodies.

How can you put your stream on a reduced-sodium diet?
Head to Izaak Walton League of America’s Winter Salt Watch page for a great list of resources for you – and your local municipality and state Department of Transportation – to help reduce your salt footprint.
Chloride Test Procedures with Hach Chloride Test Strip
- Find a clean small glass or plastic cup.
- Using water from the stream, rinse out your cup 3 times.
- Fill the cup with about an inch of stream water. (The test will not work if the top half of the test strip is submerged.)
- Place the chloride test strip into the cup with the “quantab” label at the top.
- Leave the strip sitting in the cup until the horizontal orange line at the top turns a dark blue or black (up to 10 minutes).
- Take a picture of your test strip on a white background on the card provided. Include a photo of the conversion chart as well, because these differ depending on the specific test strip you are using!
- To read the test strip, locate where the tip of the white peak falls on the scale. You can convert these units to parts per million (ppm) with the table below.
- Upload your picture and data to the NJ Watershed Watch Network.
