Groundwater pumping

Principal Option for Containment/ Recovery Excavation Vacuum extraction Temporary cap/cover Hydraulic modification No action Groundwater pumping Subsurface drains Hydraulic barriers Low permeability barriers No action Overflow/underflow containment (i.e. oil booms) Run off/run on control Diversion/collection No action Capping/ nsulation Operations modifications Gas collection/removal No action... [Pg.119]

This case serves to point out the importance of maintaining a constant hydraulic gradient on the inside and outside of a slurry wall. This can also become a factor if slurry walls are used with groundwater pumping systems (extraction wells). Then water must be reinjected to maintain a... [Pg.133]

Following the implementation of the remedy, the state or the potentially responsible party (PRP) assumes responsibility for the operation and maintenance (O M) of the site, which may include activities such as groundwater pump and treat, and cap maintenance. Once U.S. EPA has determined that all appropriate response actions have been taken and cleanup goals have been achieved, the site is deleted from the NPL through a formal rulemaking process. [Pg.469]

Soil vapor extraction (SVE) can be used to remove volatile contaminants and, when combined with another technology, to treat nonvolatile contaminants. If contamination has reached the aquifer, it is necessary to use SVE in combination with groundwater pumping and air stripping. [Pg.633]

For the site remediation case shown in Figure 16.21, this alternative consists of in situ SVE of TCE-contaminated soil (Area 2), in situ soil fixation of lead-contaminated soil (Area 1), cap (Area 1), and the groundwater pump-and-treat components of Alternative 3. [Pg.648]

Extracted vapors and liquids are commonly treated aboveground. The types of technologies used for aboveground treatment are similar to those used for SVE and groundwater pump-and-treat, respectively, and they are discussed further under those technologies. More detailed information relevant to the application of MPE at sites in general or contaminated with MTBE and other oxygenates is available in Refs [47-49],... [Pg.1012]

In addition, cover systems are also used in the remediation of hazardous waste sites. For example, cover systems may be applied to source areas contaminated at or near the ground surface or at abandoned dumps. In such cases, the cover system may be used alone or in conjunction with other technologies to contain the waste (e.g., slurry walls and groundwater pump and treat systems). [Pg.1059]

Maintenance and operation of single-stage continuous powdered activated carbon system, 10 gal/min wet-oxidation unit, solid disposal, groundwater pumping, neutralization, and effluent discharge. [Pg.405]

Total implementation costs were less than first-year construction and operating costs for conventional groundwater pump and treat. [Pg.1004]
