Pay-for-Performance (PfP) remediation aligns ERFS goals with the site owner’s goals – to reach the project endpoint rapidly and efficiently. ERFS’ PfP proposals and contracts define the soil and groundwater treatment area/volume, the desired remediation endpoint, a lump sum dollar amount for project completion, and a breakdown of payments assigned to project progress milestones. ERFS has completed PfP contracts for DoD, Superfund, private industry, bulk storage, retail fuel sites and residential sites.
ERFS performs over 75% of its work under PfP contracts and has been offering this contract option since 1998. Costs are determined using an actuarial methodology which weighs risk factors such as soil type, depth interval, type and severity of contamination, desired goals/endpoints, and general site setting.
PfP can be conducted at sites with varying soil or bedrock types, at shallow or deep vertical intervals, over very small or very large areas, and for a wide range of contaminant severity and type. ERFS has completed PfP projects in bedrock, tight clays, and loose sands while treating both soil and groundwater.
ERFS successfully treats free product (LNAPL or DNAPL), very high dissolved phase contaminant concentrations and very low dissolved phase concentrations, reaching No Further Action (NFA) at dozens of sites around the United States. Petroleum contaminants have included petroleum solvents, mineral spirits, gasoline, jet fuel, diesel, and heating oil (Nos. 2, 4, and 6). ERFS has also effectively treated chlorinated compounds including dry cleaning fluids, industrial solvents, and mixed waste containing chlorinated solvents. ERFS also has remedial experience with PCBs, chlorinated ethers, and inorganics including lead, chromium, and arsenic.
PfP remediation approaches can be developed to address source areas or the entire plume. Project endpoints depend on the site owner’s exit strategy for the site. This can range from simple removal of free product to almost total contaminant reduction, achieving closure levels for all contaminants in all locations. ERFS has successfully reached “below method detection limits” cleanup goals for a wide variety of organic contaminants. PfP contracting has also been successfully used to complete remedial activities at active remediation sites (including pump and treat and air sparging), saving thousands in O&M costs.
Under PfP contracting, ERFS includes the installation of all necessary injection points, all chemical and/or biological remediation reagents, labor, travel, and equipment to meet the project goals. Typically, the incumbent consulting engineer continues to manage overall site activities, interface with regulators, prepare all deliverables, and collect all samples for laboratory analysis.
PfP contracting matches the owner’s goals with the cleanup contractor’s goals -- to finish the project on-time and on-budget. PfP can be applied in many scenarios and can fit into many strategies for site closure while providing risk and cost controls to the site owner.
