Geological / Groundwater Evaluation

Site Characterization Another specialty of Gredell Engineering, our site characterization services include the subsurface investigation methods and techniques to properly characterize the geologic and hydrologic conditions underlying a site. Through sample collection and characterization of soil, bedrock and groundwater, our staff geologists possess the experience and expertise in characterizing a site's geology and hydrogeology. Well Construction Gredell Engineering provides monitoring well and piezometer construction services in general accordance with the Missouri Department of Natural Resources (MDNR) 10 CSR 23-4 regulations. Our well construction experience includes installations in soil and bedrock using drilling methods such as hollow-stem auger (HSA), solid-flight auger (SFA), direct-push, sonic, air rotary and rotary-wash techniques. Groundwater Monitoring Systems & Data Management The design, installation, monitoring and data management of groundwater monitoring networks is another specialty here at Gredell Engineering. We design groundwater monitoring systems, and prepare sampling and analysis plans (SAP). Through characterization of the subsurface geology and groundwater quality across the groundwater monitoring network, we apply statistical analysis techniques to determine an appropriate and effective statistical approach in accordance with the regulatory requirements. Hydrogeologic Flow Analyses Gredell Engineering hydrogeologic flow analyses services begin with an extensive description of the subsurface through the collection of soil samples and/or whole-rock obtained during subsurface characterization activities (e.g., drilling). Geophysical well logging to correlate discrete intervals, packer and aquifer testing to determine the hydraulic conductivity value of the geologic strata, and two- and three-dimensional groundwater modeling techniques are just a few of the services we provide at Gredell Engineering.
