4.1 This guide allows the decision maker to determine which remedial treatment processes are and are not applicable to remediate an area of soil, surface water or ground water that contains contaminants of concern.

4.2 This guide provides the data to make cost comparisons of the remedial treatment processes.

4.3 Analysis of treatment process design data can often be performed at the site with field instruments and test kits.

4.4 Tables 1 and 2 are a guide to selecting and obtaining physical and chemical treatment process design data. Data marked with an "X" is needed to evaluate alternatives and select a remedial treatment process. Once the remedial process is selected the additional data that are needed to design the selected remedial treatment process are marked with an "O." It may be advisable to also collect the data marked with an "O" during the initial sampling event to minimize sampling trips to the site.

4.5 Tables 3 and 4 list laboratory and field methods for analyzing this data. More than one analytical method may be listed. The most suitable method must be chosen for each application.

4.6 This guide does not address sampling for contaminants of concern and sampling locations. See EM 200-1-2 Technical Project Planning (TPP) under Engineering Manuals⁶ for information on sampling contaminants of concern. It is recommended that the treatment process design sampling be coordinated with the sampling for chemicals of concern to minimize duplicate sampling and trips to the site.

4.7 This guide does not address physical and chemical properties related to contaminant transport. This is addressed in Guide D5730.

4.8 This guide does not address why the data is needed to evaluate each treatment technology. This information is addressed in the Federal Remediation Technologies Roundtable (FRTR) site at http://www.frtr.gov in the U.S. Army Corps of Engineers guidance documents at http://www.usace.army.mil/inet/usace-docs/ and the United Facilities Guide Specifications (UFGS) available at http://www.ccb.org/.

4.9 This guide does not address Quality Assurance/ Quality Control (QA/QC) or sampling design strategy. See U.S. Army Corps of Engineers Engineering Regulation ER 1110-1-263 and Engineering Manual EM 200-1-3⁶ for information on QA/QC. This needs to be addressed in the Quality Assurance Project Plan (QAPP).
