Remedial Design & Implementation
Stone provides a full range of remedial planning and implementation services from simple to complex. We provide remedies that address cleanup of contaminated groundwater, soil, bedrock, and sediments, light or dense non-aqueous phase liquids (LNAPL and DNAPL), and we perform the design and implementation of systems to mitigate vapor intrusion. Whether site cleanups are driven by state regulations, federal (CERCLA, RCRA, or TSCA) and whether cleanup goals are based on published standards or are risk-based criteria, we are prepared to develop appropriate strategies to meet regulatory requirements. For sites regulated under TSCA, we can help our clients navigate through Self-Implementing, Performance Based, or Risk-Based Cleanup and Disposal projects. We have no proprietary interest in any particular technologies or processes, and therefore are able to provide an unbiased selection of remedial approaches that best meet our clients’ needs based on schedule, cost, and effectiveness. Often this is best achieved by pilot testing of remedial technologies before implementation.
Stone staff have experience with design and implementation of the following types of remedial projects:
- Excavation, transportation, and disposal
- Capping and/or containment of contaminated soils or building surfaces
- Stabilization/solidification
- In situ treatments such as oxidation, reduction, and bioremediation
- Groundwater extraction and treatment
- Soil vapor extraction and air sparging
- Sub-slab ventilation and depressurization
We also have extensive experience performing the remedial planning and implementation at Brownfields redevelopment sites, as well as optimizing existing remedial systems to increase efficiencies and reduce remedial time frames -- from both an energy and cost perspective. Our designs take into account green remediation principles and strive to maintain a small carbon footprint for design and implementation of all of our projects.
