Aquifer Testing and Groundwater Modeling

To fully evaluate conditions at a contaminated site, the characteristics of the impacted water-bearing zone (aquifer) must be established. Status professionals are well versed in a variety of aquifer testing techniques used to stress the aquifer under pumping conditions, allowing the aqufer characteristics to be measured and quantified.

The data derived from the aquifer testing is used in a variety of ways to establish the characteristics of the contaminant plume and to address how it should be remediated. These data are used to evaluate if pumping and treating the contaminated water is a practical approach, and if so, what type of groundwater extraction technique might be most appropriate. The data are also used to select and design groundwater treatment systems that will effectively handle the rate and volume of water that is expected to be produced.

Evaluating how and where dissolved contaminants will likely migrate requires models to be constructed that can predict future contaminant movement. Our experienced professionals use computer-based numerical models to evaluate if contaminant migration presents a risk to human health or the environment. Our detailed understanding of the subsurface conditions (gathered during site assessment) and the numerical measurement of the aquifer (from the pumping tests) are used to define a model that reflects current site conditions. This model can then project likely future scenarios for various remedial options.
