Suitability of the Hydropunch(trademark) for assessing groundwater contaminated by volatile organics.

摘要

The Hydropunch is a groundwater sampling device developed for rapid and cost effective collection of groundwater samples from any depth. A study was conducted at the Savannah River Site to evaluate the tool's performance in collecting groundwater samples for waste site characterizations. Hydropunch samples were collected from two locations adjacent to each of five wells monitoring groundwater contaminated by volatile organics. At each location, Hydropunch samples were taken at three evenly distributed depths within the interval corresponding to the screen zone of the adjacent monitoring well. Groundwater samples were collected concurrently from the monitoring wells. All samples were analyzed using a Gas Chromatograph/Mass Spectrometer to detect any of twenty-five volatile organic contaminants. This field evaluation demonstrates that the Hydropunch is a reliable screening tool for determining the distribution and concentrations of volatile organic contaminants in groundwater. 6 refs., 3 figs., 3 tabs.
