Road salt is increasing in freshwater streams in New Jersey. Help us quantify it by participating in our monitoring study!
Our goal is to collect at least 4-6 measurements from each monitoring site, with 2-3 collected during dry conditions and 2-3 collected during or after rain, snow, or snowmelt. You may select your own monitoring site(s) or we can assist you with locating an accessible section of your stream or lake.

Chloride Levels in New Jersey
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.
- Thank you!
