Alpha personnel apply their technical capabilities in subsurface characterization and hydrologic analysis to address issues related to subsurface disposal of waste water. Alpha's project experience has included work associated with existing and proposed subsurface disposal systems. These projects generally include:

Preliminary site characterization through sources such as soil maps, topographic maps and well logs, and through site reconnaissance, to determine a site's subsurface disposal potential. Subsurface investigations to determine soil properties, depth to bedrock, and site stratigraphy, and to evaluate the variability of these characteristics across the site. Percolation testing to assess the hydrologic capacity of different soil types. Installation of ground water monitoring well networks.

Determination of depth to ground water, the water table configuration, and seasonal variations in ground water flow directions. Evaluation of aquifer properties such as hydraulic conductivity, transmissivity, and specific yield, using pumping tests and slug-tests. Ground water mounding analyses to evaluate the response of the water table to hydraulic loading beneath proposed absorption fields. Assessment of ground water quality and potential impacts from subsurface wastewater disposal.
