has experience in evaluating hazardous waste sites and in the preparation and implementation
of soil and groundwater sampling programs. David has successfully closed sites under the
Texas Risk Reduction Program (TRRP). He has experience in testifying as an expert witness
concerning numerous cases where hazardous constituents were at issue with a site.
His other experience includes the development of Spill Prevention, Control and
Countermeasures (SPCC) plans and air permits (usually a PBR if not de minimus) for oil & gas
operators in the East Texas Basin including oil handler training. David has extensive experience
in environmental forensic studies from the characterization of industrial waste streams to
evaluating releases of unknown substances to the environment. He has designed and installed
groundwater monitoring wells (single and multiple cased wells), installed groundwater treatment
systems, Vapor Extraction Systems (VES), and in-situ and ex-situ bio-remediation systems.
David manages water intrusion events during construction projects by assembling a team of

The City of Dallas and TCEQ approved the MSD application. |
VCP Closure of a Semiconductor Facility in West Texas |
David |
Conducted site investigation, decontamination and closure oversight of a former semiconductor assembly building. Site investigation efforts concluded that the facility’s waste collection system had leaked over time and released trichloroethylene (TCE) into soils at the site.

The project involved installation of groundwater monitoring wells to delineate the horizontal and vertical extent of affected media. Geological cross-sections and geological subsurface maps were drawn to evaluate the site’s geology. Numerous subsurface maps of groundwater contaminates were drawn to illustrate the dimension and character of the groundwater plume. Observed and monitored the installation and operation of a potassium permanganate injection system utilized to treat the chlorinated solvent affected groundwater. Conducted groundwater sampling to evaluate the effectiveness of the potassium permanganate injections. The project has been closed and the property was sold. |
