“Swamp 5” refers to wetland S5 in this map of streams and wetlands SW of Sandy Lake. It has been highly degraded by industrial activity as shown in the Google Earth Images below.
We have been monitoring water coming from the associated stream where it comes out of a culvert under the Dairy Road and then flows into Murphy’s Pit. It has consistently had the highest EC (Electrical Conductivity) values of any of the streams we have been monitoring, also the water is very turbid, sometimes quite milky with a lot of fine materials in it.
For EC values, View:
Generally the flow out of the culvert and on into Murphy’s Pit is very low compared to other streams converging on Murphy’s pit, so while the water has a high salt content, its influence on salt content of Sandy Lake may not be very significant. However, the highly turbid and sometimes milky water is concerning and should be further investigated. It would be appropriate as well to do an ion analysis of the water to determine how much of the salt content is associated with road salt (indicated by chloride content), and if there are other constituents of concern in it.
