Mr. Mesard has extensive experience as a hydrogeologist, engineering geologist, and civil engineer. His expertise includes design and implementation of environmental investigations; remediation system design, evaluation, and failure analysis; geologic hazard analysis; and construction defect assessment. 

Mr. Mesard's principal area of specialization is environmental release reconstruction and source identification (environmental forensics), including chemical-characteristic analysis (chemical fingerprinting), the dating of chemical releases, and chemical fate and transport.

Mr. Mesard has assisted his clients on various CERCLA, RCRA, and state-equivalent sites, to identify and quantify the contributions of specific sources, evaluate the technical appropriateness and costs associated with remedial actions, and assess the consistency with state and federal regulations — specifically the national contingency plan (NCP). Mr. Mesard also has expertise in quantifying the flux, timing, and extent of chemical releases for dose reconstruction estimates related to toxic tort claims. Mr. Mesard has written technical reports and/or testified as an expert in projects involving chlorinated solvents, solvent stabilizers, perchlorate, petroleum hydrocarbon compounds, MTBE and other oxygenates, polycyclic aromatic hydrocarbons (PAHs), PCBs, dioxins and furans, various pesticides, and metals.

Mr. Mesard's areas of interest include risk management and decision analysis in assisting financial, legal, insurance, and commercial clients in quantifying and assessing the risks and costs associated with environmentally distressed properties, and in allocating environmental responsibilities and costs among responsible parties in cost-contribution and cost-recovery efforts.
