EPA. 1987a. Superfund record of decision (EPA Region 4) Gallaway Ponds site, Gallaway, Termessee, September 1986. Washington, DC U.S. Environmental Protection Agency. EPA/ROD/R04-86/013. NTIS PB87-189080. 

Populations living near the RMA may be at risk of exposure to diisopropyl methylphosphonate. Individuals with diisopropyl methylphosphonate in their domestic wells are receiving their drinking water from alternative sources. According to the On-post Record of Decision (June 1996), well owners with wells contaminated above 0.392 g/L of diisopropyl methylphosphonate could be connected to a municipal water supply. 

During the detailed analysis, each alternative is assessed against the evaluation criteria. The results provide decision-makers with sufficient information to adequately compare the alternatives, select an appropriate remedy for a site, and demonstrate satisfaction of the CERCLA remedy selection requirements in the record of decision ...

NPL Superfund Records of Decision (RODs) were loeated for 24 of the 27 currently listed NPL sites where the HazDat database lists 3,3 -diehlorobenzidine as a eontaminant. A ROD is a legally binding doeument that states the results of investigation and feasibility testing at hazardous waste sites and tells what techniques will be used to remediate the site. At four of the sites, 3,3 -dichlorobenzidine was verified as a contaminant. The RODs for the other 20 sites did not mention 3,3 -dichlorobenzidine as a contaminant of concern (i.e., one that warrants development of cleanup criteria and a choice of remedy). Affected soil was removed from three of the four contaminated sites. Only one site, Bofors Nobel in Michigan, required development of a cleanup criteria (CPMA 1998). 

At the Environmental Protection Agency s (EPA s) Perham Arsenic Superfund Site in Perham, Minnesota, a continuous-backwash filtration unit is used to treat groundwater contaminated with arsenic. In 1994, according to the EPA Record of Decision (ROD) at the site, the present worth costs of the remediation were 2,548,776. The annual operations and maintenance (O M) costs were projected to be 217,805 (D17114C, pp. 2-3).

ETG supplied thermal desorption technology at the Southern Maryland Wood Treating Superfund site. From 1997 through 2000, it was estimated that the thermal desorption costs at the site were 60,450,429 (including pending costs and potential modifications). The estimated completion cost for this application was 221 per ton. This was within 4% of the estimated cost in the record of decision (ROD) ( 214 per ton) (D22906L, p. 20). 

A feasibility study is necessary after the remedial investigation to make sure the proper remedial action has been selected. Once that has been completed, the USEPA publishes a Superfund Record of Decision (ROD), which describes the remedial action selected. The next step is the remedial design/ remedial action phase, which can include ... 

After lead, arsenic is the most common contaminant at US Superfund National Priorities List (NPL) sites (EPA, 2002a, 2). As of 2002, arsenic was a contaminant of concern at 568 or 47% of 1209 NPL sites with records of decision (RODs) (EPA, 2002a, 2). Among the arsenic-contaminated sites, 380 of them have contaminated groundwater, a total of 86 have arsenic-contaminated surface water, and the number of sites with arsenic-contaminated soils and sediments are 372 and 154, respectively (EPA, 2002b, 2.2). Appendix B in US EPA (2002b) lists the locations of Superfund sites where arsenic is a contaminant of concern.

On April 9, 2007, tire CDCAB recommended that all agent and energetic hydrolysate generated at the BGCAPP should be treated on site via the secondaiy treatment process identified in the 2003 Record of Decision—SCWO (CDCAB, undated, p. 1). It listed reasons such as controversies and uncertainties associated with transportation and treatment at conunercial facilities the initial Record of Decision for the design of BGCAPP, which included the use of SCWO the economic benefits of local work and a belief that offsite disposition would result in minimal cost savings. In addition, members of the CDCAB told the committee that they believe that the Army has not demonstrated a method that adequately characterizes VX concentrations in VX hydrolysate. 

The understanding that ACWA had committed to onsite hydrolysate treatment when it signed the records of decision for tire two sites in 2002 (Pueblo) and 2003 (Blue Grass). Community members are dismayed and believe that the offsite option keeps coming up because DOD has already decided to implement it.

One potential application is the use of neural networks to facilitate decisions about hazardous waste sites. These sites generate a great deal of data, in which patterns are inherent. Sites that once produced batteries, for example, will typically show a great deal of cadmium in the soil this finding usually leads to a decision about a particular form of remediation. A network s input layer could represent characteristics of hazardous sites (such as type of site, volume of contamination, type of contaminants, contaminated media, etc.), and its output units could correspond to possible decisions regarding methods of cleanup. Such a network could be trained and tested on RODS (Records of Decision) to establish the appropriate relationships and assess the network s accuracy.
