From the first set of data gathered before the winter season, this group can
conclude that with the exception of the Monroe Street samples, there is no
difference in the chloride concentration between the top and bottom soils. In
regards to the Monroe Street location, the lower core sample is 10 mg/L higher
than the upper core sample.
The post-winter results show that the Monroe Street levels switched, and the upper core sample’s chloride concentration became higher than the lower core sample. The Monroe Street location and the Edgedome location both showed higher chloride concentrations in the post-winter results. The Raingarden location showed no difference between the pre-winter and post-winter results.
