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 such as 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 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, or 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 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).

What our clients say

On a complex and sensitive remediation project SoundEarth excelled where other engineering and project management groups would have struggled. Moving large volumes of contaminated materials through a limited access easement, reconstructing sensitive slopes across property boundaries in the shoreline, and managing the social relationships of surrounding property owners along a well established section of the Lake Washington shoreline, SoundEarth’s attention to important details yet flexible management style kept the project moving forward. In addition to apparent strong site and project management skills, SoundEarth staff have the ability to navigate municipal processes working effectively with permit review staff and decision makers. By maintaining open and useful communication with all stakeholders, SoundEarth kept all interested parties informed and updated eliminating the need to ask questions.
