Flow weighted sampling of tide influenced storm water
Does anyone have experience with or equipment suggestions for sampling storm water during a rain event in storm lines that are often submerged in salt water? Due to the number of locations, the equipment needs to be automated to a great extent. Our approach is to monitor the conductivity to make sure there is no seawater intrusion and then check for a flow height/velocity increase over the base flow to trigger a sampler. The sampler would then begin taking a flow weighted composite sample or a series of discrete samples. The discrete samples would allow discarding any that showed salt-water contamination. Any suggestions are appreciated. mcollamo@ci.tacoma.wa.us
