According to the dataloggers, winter salt season is certainly over. During the winter, conductivity levels would spike with every snowstorm. Now that we have had several spring storms, we are seeing conductivity dropping each time it rains. When it rains, the water level in the stormwater pipes rises (blue triangles). In February, the spikes in water coincides with a high spike in conductivity (black line). Once we get into March, rainfall stopped triggering spikes above 1000, the apparent baseline in this location (red line; note that the times when conductivity is 0 are times when the sensor on the logger was out of the water). For those volunteers who have not already, please send me any data you have collected this winter. And if you want to see what the volunteers have found, visit our data collection. Keep an eye out for an updated GIS map of the data this summer.
