ABSTRACT
Relative to physical and mechanical methods of treatment, the use of in-situ chemical and bio-chemical treatment methods for soil and ground water contamination has seen a significant increase over the past two decades. Many factors are driving this shift including technological improvements of injection technologies, availability of numerous new products, a better understanding of the geochemistry and biochemistry of aerobic and anaerobic processes, requirements for less site and infrastructure disturbance, the need for greener and sustainable treatment methods, the lower carbon footprint of these methods, and other economic factors.
In the rush to move into the clean up phase for a contaminated site, injection designs are often based on the initial site characterization data. Even though ground water monitoring us usually current, soil data is often very old, and all of the data is only two dimensional and does not have quantitative data in the vertical components which is required to design the treatment. Without collecting additional data in all three dimensions to properly design a remediation program, the dosing and targeting of the contaminant plume is doomed to fail. Contaminant mass, soil oxidant demand, lateral and vertical quantification of contaminant concentration needs to be measured. When this is not done, treatment reagents are often wasted by injecting too much into low concentration areas and not enough in the high concentration areas.
Numerous “Triad” type characterization methods can aid in the remediation design including subsurface imaging tools, direct-push continuous core and discrete water sampling, mobile laboratories, membrane interface probes and other technologies. Subsurface imaging includes tools like the Membrane Interface Probe (MIP) with selective detectors, Electrical Conductivity (EC) Probe, Laser Induced Fluorescence (LIF), and the Hydraulic Profiling Tool (HPT). The Interstate Technology and Regulatory Council (ITRC) recently published guidance for the “Incremental Sampling Method” (ISM) which is a statistical method of sampling a “Decision Units” (DU), similar to compositing, at increments resulting in more accurate calculations of total mass present which provides for accurate dosing calculations of chemical treatments. Numerous biological evaluation tools have been developed that can assist with fine tuning enhanced bioremediation options.
Early in-situ treatment delivery methods used available delivery means such as injection through existing monitoring wells, well socks, and borehole or trench placement. Direct push technology (DPT) was soon discovered as a more efficient delivery method of treatments and improved physical contact and contact time of the treatment chemicals with the contaminants. Early methods used simple “bottom-up” injection methods which will not properly place the treatments in most heterogeneous soils. Numerous types of new injection tool, methods, hydraulic fracturing techniques, have since been developed that improved the ability to target inject and make contact between the treatment chemicals or biologic systems and the contaminant of concern. Advances in real-time monitoring have furthered the ability to monitor the performance, distribution, and rate of treatment both spatially and temporally in both unconsolidated and fractured-bedrock media.
Phasing different types of treatments, both ex-situ and in-situ, can be more than trying to apply one method throughout the entire clean-up process. The cost efficiencies of different types of treatment methods is a function of the contaminant concentration, high versus low.
