Leggette, Brashears & Graham, Inc. (LBG), and its LBG-Guyton Associates division, have a long history in investigating ground-water contamination associated with oil field operations. The firm has accumulated a broad range of expertise having worked on approximately 100 such projects. Aquifers impacted with produced water are often characterized by elevated salinities, dissolved petroleum hydrocarbons and/or the presence of radioactive/NORM species. Well blowouts or leaking production wells can introduce natural gas and its associated liquids into aquifers.
LBG is very experienced in the characterization of aquifers and differentiating between
naturally occurring compounds and "contamination" introduced by oil and gas production. LBG uses its extensive hydrogeolgical skills in conjunction with detailed geochemical analyses determine whether specific sources of "contamination" can be identified and
differentiated. Close cooperation is maintained by LBG-Guyton hydrogeologists with their clients and attorneys to ensure the necessary information is developed in an expeditious manner and properly presented in reports and/or expert testimony. LBG has represented their clients before regulatory agencies and within the courtroom.
