CHAPTER 5
DOCUMENTING TECHNOLOGY PERFORMANCE
5-1. General. This chapter provides additional information on documenting technology
performance in the RA report, expanding on concepts presented in the previous chapter
(Paragraph 4-6). Technology performance should be documented in Section 5 and Appendix A
of the RA report.
5-2.
Recommended Performance Reporting.
a.
The performance of a technology is often characterized only in terms of the
percentage of contaminants removed or the concentration of contaminants remediated.
However, that information alone will not adequately assess all aspects of a technology's
performance. For example, this one-dimensional measure of performance will not document any
of the problems that might have arisen during the technology's application, or how such
problems were resolved. The information listed in Exhibit 5-1 should be included in the RA
report so that the effectiveness and the appropriateness of the remedy can be quantified and
compared with other alternatives when making future remedy selections at other sites with
similar characteristics.
b.
Exhibit 5-1 provides a guide to ensure that all important information related to the
performance of the technology will be documented in the RA report. The level of detail and data
available for each performance topic will vary by technology type and the specific application.
Exhibit 5-1
Recommended Performance Reporting
Performance Topic
Type of Information
♦
Types of samples collected
Types of media sampled
♦
Types of constituents analyzed
♦
Use of surrogates (e.g., soil gas as a surrogate for soil borings)
♦
Sample frequency and protocol
Where samples were collected
♦
How samples were collected
♦
When samples were collected
♦
Who collected samples
♦
Quantity of material treated
Quantity of material treated during application
♦
For in situ technologies, area and depth of contaminated material treated
♦
Measurement of initial conditions (even if not required to demonstrate
Concentrations of untreated
compliance with cleanup/remediation criteria)
and treated contaminants
(range and median values)
♦
Measurement of concentrations of contaminants during or after treatment
(note whether data exists for both treated and untreated contaminants or
whether operating data exists that corresponds with performance data)
♦
Assessment of percent removal achieved (note procedure used to derive
percent removal)
♦
Correlation of performance data with other variables
