Specifications include, but are not limited to: All investigative activities must be performed by a UST Class I certified contactor as required by R.61-98. High Resolution Site Characterization (HRSC) consists of strategies and techniques using scale-appropriate measurement and sample density to define contaminant distributions, and the physical context in which they reside with greater certainty; supporting faster and more effective site cleanup. HRSC is completed utilizing a number of down-hole profiling tools that vary in collecting specific real time data from the subsurface. Qualified interpretation is paramount due to the complexity of the data collected from various innovative profiling tools. Due to the possibility of false positive data, interpretation by an experienced practitioner will be required to provide precise and accurate data. The company conducting data collection, interpreting the data, and comprising the 3D modeling of the HRSC data must have at least 3 years of experience with HRSC. The reports requested in this bid solicitation must include high resolution GIS imagery and traditional basemap features (e.g., CAD drawings, topographic maps, or aerial photographs), that can be combined to represent the ground surface in three-dimensions with the photographs or maps precisely placed on the topographic surface. High resolution, direct sensing data such as laser-induced fluorescence, membrane interface probe, hydraulic profiling tool, and electrical conductivity must be used to enhance the accuracy and usefulness of the model. The three-dimensional models will then incorporate lithologic information from boring logs, as well as analytical results from soil and groundwater samples. The synthesis of this information into an interactive database visualization tool allows the distribution of contaminants to be clearly shown within the hydrogeologic framework and can be used to demonstrate how the various media interact in the subsurface.
