Use of Multi-Level Wells in Developing a 3-Dimensional Understanding of Groundwater Flow and Contaminant Migration at the Savannah River Site
Understanding the flow of groundwater and contaminants in 3-dimensions, along with hydraulic properties, is instrumental in selection and implementation of successful remediation efforts. Advances in multi-level groundwater monitoring at the Savannah River Site (SRS) are enabling engineers and geologists to collect the needed characterization data in an efficient, cost-effective manner. The SRS has developed a new multi-level groundwater monitoring well, "StrataSampler", which is being deployed for characterization and monitoring at several large groundwater plumes on the SRS. The installation method used allowed collection of data during the drilling process allowing optimization of screen placement within the aquifers and minimization of drilling costs and waste generation. Data generated during the installation of the StrataSamplers along with data collected from the installed wells is being used to understand the 3-dimensional nature of contaminant fate and transport. The L-Area Southern Groundwater Operable Unit is the first full-scale deployment of StrataSampler wells at SRS. Twenty-two StrataSampler wells with a total of 52 sampling zones were installed. The installation, development, hydraulic testing, sampling of the StrataSamplers at this unit and the resulting understanding of the contaminant plumes will be discussed in the paper and presentation.
