ESA provides full turnkey remedial design and implementation services. Proper remedial design is needed to effect remediation to an appropriate level. While "the appropriate level" is relative to each project, it usually means designing a program to meet the minimum requirements for compliance so the fewest dollars are spent. Remedial designs include soil excavation and disposal or recycling, soil reuse plans, drum removals (both surficial and buried), groundwater cleanups, lagoon closures, building decontamination (PCBs and other hazardous materials including asbestos), chemical oxidation, and bioremediation.
On occasion, projects require a more complicated remedy. For example, when heating oil finds its way beneath a structure, it can present a complicated remedial challenge. New shoring methods have emerged and have gained wide acceptance. These methods include mini-piles and helical piers. When properly designed by a licensed civil engineer, a house (even a very old one) can be supported to allow excavation to occur well beneath the structure. These methods are so secure that most structures experience virtually no shifting. Walls remain plumb and do not crack, and doors still open and close with ease.
It is beyond the scope of this Web site to describe in detail the myriad remedial technologies that one can select. When an impacted site requires in situ remediation, ESA must choose from technologies such as bioremediation, bioaugmentation, chemical oxidation, chemical reduction, physical removal, minimization technologies, stabilization, and much more. ESA examines the universe of commercially available technologies and selects the one that lends itself to your particular application. Remember one very important fact: all remedial technologies work, but not all technologies work equally well in every situation. It is ESA's responsibility to determine what technology is best for your particular site by taking into account the actual contaminants, geology, site constraints, timing, and etc.
