Environmental Hydrogeology

Hydrogeology is relevant to nearly every service SoundEarth provides. Our hydrogeologists develop and interpret data to perform a range of services, such as dewatering analysis, settling during construction, thermal monitoring in sensitive receptors (trout streams), sophisticated numerical modeling and statistical analysis, and pinpointing the technical and regulatory issues for groundwater quality.

Our tools include the latest in geographic information and web-based data systems, including a suite of data interpretation products, ranging from ESRI’s Spatial Analyst to Rockworks. We also use geospatial data statistics to evaluate existing site information and identify remaining data gaps.

Modeling and assessing fate and transport of chemicals is a core expertise at SoundEarth. After gathering field data, we use software tools to characterize the hydrogeological conditions at contaminated sites and quantify environmental impacts to soil, air, and water. These software tools include our own models of chemical and groundwater fate and transport, as well as public domain codes such as ATRANS and MT3DMS (to simulate advection, dispersion, and chemical reactions of dissolved constituents and to develop 3-D solutions to transport), the USEPA’s HELP model (for use in landfill design and to predict leachate production), and Johnson-Ettinger’s indoor air model (to estimate vapor intrusion into buildings).
