Aptos, Ca

-Specializing in environmental geochemistry at mine sites, from planning through operations, and into remediation and final closure. Projects include hydrogeochemical studies of metals in the environment; acid mine drainage; interactions between geochemistry and geotechnical behaviors; geochemistry of pits and pit lakes; planning mine closures; cyanide hydrogeochemistry at mining sites; water-quality site investigations; geochemical modeling; LNAPL and DNAPL contamination of soils, ground water and surface water; and radiological geochemistry.

Denver, Co

Specializing in hydrogeochemistry and hydrogeology, particularly applied to mining and wastes. Projects include geochemistry and mitigation of acid-rock drainage; hydrogeology and water quality studies of mine reclamation sites; field and laboratory studies of contamination problems associated with waste-rock piles and tailings impoundments, uranium and radium mill tailings remediation; review of major waste management projects for private clients and government agencies; unauthorized and inadvertent waste disposal, treated wood products; cyanide hydrogeochemistry; underground injection control; and geologic disposal of radioactive materials.

Silver Spring, Md

Responsible for reviewing hydrogeologic and hydrogeochemical aspects of license applications and related documents and for formulating staff technical positions on hydrogeologic issues, including applications of probabilistic risk assessment to nuclear waste management. Projects included hydrogeologic and hydrogeochemical evaluations of potential HLW disposal sites, abandoned mill tailings sites, and groundwater restoration of in situ uranium leaching sites. Division reviewer for Office of Research projects in waste management.
