The use of computer simulation and predictive models can be an important tool in water resources, environmental investigation and remedial planning. EndPoint personnel have successfully applied models to:  assess long- and short-term human and environmental risk associated with the fate and movement of contaminants in the environment, design cost-effective environmental cleanup remedies, ensure long term sustainable use of surface water and ground water resources, and evaluate peak runoff rates and river stage for hydraulic design.  EndPoint personnel have successfully used the following types of models:

  • Ground water flow;
  • Solute contaminant fate and transport;
  • LNAPL and DNAPL migration;
  • Soil vapor transport;
  • Unsaturated flow;
  • Surface water flow; and
  • Water resources and hydrological models.

Common applications of models can range from the development of three dimensional, multi-media contaminant transport models to predict the distribution of contaminants in environmental media to the simple use of an analytical equation to estimate one-dimensional discharge of ground water to a stream. The use of regulatory-accepted models coupled with the collection of site data can be an important component in environmental planning and problem-solving. At EndPoint, we recognize that the complexity of the model used should be commensurate to the level of study required.
