An optimized phytoscreening method was used to locate a chlorinated ethene plume discharging into a stream. Trees along the stream bank were monitored through different seasons under different environmental conditions to evaluate seasonal uptake/loss scenarios. Detection of VC, cis-DCE, TCE, and PCE in the trees showed that phytoscreening is a viable method to locate chlorinated ethene plumes, including VC, discharging to streams. Phytoscreening for VC was found to be more sensitive to environmental conditions affecting transpiration than the other chlorinated ethenes detected.
