1988 Sudden Stream Drilling Muds Effects on Vegetation
Cook M. 1988. 1988 Sudden Stream Drilling Muds Effects on Vegetation
Vegetation was surveyed at the Sudden Stream waste site to describe the effects of drilling mud wastes on the surrounding vegetation, to evaluate plant colonization at the site, and to prepare a vegetative map of the waste area. Because toxic levels of chromium have been found in the ground water near the site and high concentrations of barium were found in soil samples and ground water samples near the site, it was suspected that vegetation would also contain elevated concentrations of barium and chromium in plant tissues. Any plants growing at the site with elevated levels of barium and chromium would be potentially toxic to herbivorous animals. Control site and affected site transects were established, plant identification surveys were conducted and species collections were made. Results indicated that chromium and barium concentrations were elevated for all species when compared with control concentrations. Differences were significant for five of the seven species tested.
