Check Out Our New Interactive Hotspot Sampling Map!

We're excited to announce that we've created an interactive map that shows the locations of our sampling points and corresponding data.


Map image example. Go to Hot Spot Page for interactive map.

We’ve been working hard all summer and into the fall to locate and eliminate pollution “hot spots”. Based off of observations in the field and from data collected from our Citizen Water Monitoring Network, we’ve been able to identify areas throughout the watershed that have suspected contamination from unknown sources.

Using this information, we go into the field and take samples, testing for pollution indicators such as E. coli, nutrients, optical brighteners, and dissolved oxygen. We use this data to alert municipalities of contamination problems so that they can be addressed.

How does the map work?

In the upper left corner, you will see icons which provide features such as a legend, among others. Right below these icons are buttons to zoom in and out of the map, and the home button takes you back to the default view.

hot-spot-interactive-map-icon-chartClicking on the legend will show you three different symbol shapes. The circle symbols represent testing that was done on water discharging from outfalls. The square symbols are for samples taken directly from a stream and the diamond symbols are places where we measured dissolved oxygen. The color-coding from green to red indicates areas where the data has come back as clean, suspicious, or problematic.

If you click on a particular point on the map, a pop-up will be displayed that lists the site’s town, stream, and description. It also shows a data table with the data collected for each point so far. You may need to use the scroll bar on the right side of the pop-up to view the data.

We will be updating this map as we collect more hot spot data and would love to hear suggestions on how we can improve it!
