Cost-effective remediation

The feasibility study (FS) utilizes the data on site characterization and remedial technology screening to establish remedial alternatives, in turn, to select the cost-effective remedial actions. The FS may be viewed as occurring in three phases ... [Pg.604]

According to treatment mechanisms, however, treatment technologies are classified as biological, physicochemical, and thermal processes. In terms of the place where the actual treatment takes place, the issue of in situ vs. ex situ comes into play as far as selecting the most cost-effective remediation processes. For example, most bioremediation processes are in situ, while physicochemical processes may be implemented both in situ and ex situ, according to the following ... [Pg.74]

In general, the design objective is to determine the most cost-effective remedial design. The cost functions for pump-and-treat remediation using granular activated carbon (GAC) derived by Culver and Shenk (1998) were adapted for this analysis. In addition to the operating costs and the treatment capital costs considered by Culver and Shenk (1998), the capital costs of well installation have also been included, and the carbon utilization costs are calculated at every simulation time step. Thus the objective function can be described as follows ... [Pg.5]

The decisionmaking method adopted in the Proposed Revisions to the NCP is a case-by-case method where analysis and consideration must be given to a range of alternatives which have been selected and analyzed. Cost, feasibility, adequacy, reliability, and potential adverse impacts on health or the environment must be analyzed. Any appropriate Federal and State standards and criteria are to be considered. Finally, under proposed Section 300.67(j) the lead agency is "to choose the most cost effective remedial alternative which effectively minimizes and mitigates the danger and provides adequate protection of public health, welfare, and the environment." (11)... [Pg.7]

In Superfund s Section 105 requirement for a Revised NCP, Congress mandated a scheme for responding to releases of hazardous materials. For old dump sites response starts with a survey and prioritization of sites based on risk assessment. After prioritization the focus turns to selection of cost-effective remedies which will adequately protect the public health and welfare and the environment. In revising the NCP, EPA is engaged in a pioneering effort to develop a practical and effective site assessment model. After prioritization additional assessment will often... [Pg.7]

Reactive transport formulations can be very useful in helping to prevent the problems caused by this phenomenon. Through numerical modeling of the injection process it is possible to estimate the damage zones evolution in the reservoir and the composition of water produced in the well. Indeed, identifying the location and composition of the scale deposit is the first step in designing a cost-effective remediation program (Crabtree et al., 1999). [Pg.599]

Thermally enhanced hydrolysis is generally the most cost-effective remediation method for halogenated alkanes, and many funaigants and pesticides. A listing of common compounds with their hydrolysis half-lives at 100 °C is shown in Table 24.4. In situ thermal methods have been successfully used to hydrolyze 1,1,1-trichloroethane (TCA), 1,1,2,2-tetrachloroethane (TeCA), dichloromethane (methylene chloride), and ethylene dibronaide to remediate groundwater. [Pg.519]

URS/Radian proposed the use of phytoremediation to treat groundwater contaminated with dissolved phase CHC at a chemical plant. The State of Louisiana regulatory agency recommended standard piunp treat technology. However, Radian was able to convince the State to use a new more cost effective remedy. Hybrid Poplar trees were planted to achieve hydraulic containment and phytoextraction of the entire dissolved plume. The shallow groundwater and long growing seasons were ideal for this remedial approach. Radian was eventually able to close the site and obtain a no fiuther action letter from the State of Louisiana. [Pg.1622]

Observational methods based on careful monitoring—before, during, and after construction—are essential in achieving reliable and cost-effective remedial measures. [Pg.352]

The study of microstructure in the contaminated frozen soil reveals the fundamental nature of the effects of a contaminant. With such information it is possible to make predictions as to the effects of a contaminant on a variety of thermodynamic and mechanical properties, which in turn will determine the effects on terrain, and the rate and direction of spreading of the contaminant. Such information allows the development of rational and cost-effective remediation procedures. [Pg.234]

From the studies of microstructure described, and the conclusions one can draw as to the effects the contaminants will have on soil properties and thus on various processes in the ground and especially in the near ground surface layers, it appears that we have the possibility of predicting the course of events at a contamination site and thus of devising cost effective remediation procedures (Williams, 1996,1998). [Pg.236]
