We have extensive experience in developing detailed cost estimates to support mediation, arbitration, and litigation of remedial solutions for impacted sites. We develop data to apportion costs reliably among multiple parties with varied operations and release histories. We evaluate life-cycle costs for varied potential remedial alternatives to allow fact-based decision making with regard to remedial system selection. (Publications)

At AME, our monitoring optimization program (MOP) quantitatively evaluates the technical value of wells at a site, optimizing monitoring well networks for practical effectiveness. Significant and substantial benefits are achieved by monitoring well optimization, including cost savings, increased safety, and reduced site disruption. MOP optimizes both the number of monitoring wells and the frequency of sampling, so results are both immediate and long term. (Publications)

At AME, we provide project management for numerous clients, serving as the prime contractor for diverse studies including assessing and characterizing the lateral and vertical extent of contaminant impacts, and designing, implementing, and operating effective, cost-efficient remediation systems. We have provided project management services for a variety of clients from major petroleum companies to manufacturing companies.

At AME, with staff experienced in soil sciences, geology, hydrology, and engineering, we are well qualified to conduct hydrogeological investigations. our investigations include infiltration and run off analyses, groundwater flux, and well field investigations. (Publications)

At AME, our NAPL expertise is supported by Dr. Jeffrey Johnson, a leading expert in the field who has published numerous technical articles related to NAPL, many of which have been coauthored by clients' staff. These technical papers address important issues, including: representative LNAPL thickness, NAPL mobility, NAPL recoverability, characterization of soil properties and capillary pressure conditions, and NAPL dissolution. In these publications, Dr. Johnson was a technical lead in the development of the API Interactive LNAPL Guide, which was spearheaded by one of our major clients. Through this technical capability, we provide expertise in the characterization and remediation of NAPL, assessment of NAPL mobility, movement and retention of NAPL within the vadose and saturated zone, mass transfer to the aqueous and vapor phases from an NAPL source, and effective solubility and mass flux calculations of dissolved impacts from NAPL.
