|
| Information on Chemicals Used in Drycleaning Operations is available as a viewable/ downloadable document and in a searchable, on-line database. These resources are intended to help those engaged in the assessment and remediation of contaminated drycleaner sites and to assist regulators conducting compliance inspections at drycleaning facilities. The document provides current and historical information on the types of chemicals solvents, other chemicals, pre-cleaning/spotting agents, garment treatments, and solvent and equipment maintenance materials used in drycleaning operations. The database provides information on drycleaning products/trade names (as listed on Material Data Safety Sheets), who manufactures or distributes them, what the products are used for in drycleaning operations, what chemical ingredients each product contains, the CAS number for each chemical ingredient, any alternate name by which these chemicals are known, and any additional information available. |

| Analysis of Selected Enhancements for Soil Vapor
Extraction (PDF) (3.2MB/246pp) |
| Order EPA 542-R-97-007 |
| This report provides an engineering analysis of, and status report on, selected enhancements for soil vapor extraction (SVE) treatment technologies. The report is intended to assist project managers considering an SVE treatment system by providing them with an up-to-date status of enhancement technologies; an evaluation of each technology's applicability to various site conditions; a presentation of cost and performance information; a list of vendors specializing in the technologies; a discussion of relative strengths and limitations of the technologies; recommendations to keep in mind when considering the enhancements; and a compilation of references. |

| Color-Tec® Screening
Process |
| Download Color-Tec® Method Description And Standard Operating Procedures (PDF) (389K/21pp) |
| Color-Tec® is a field-based analytical method developed by Ecology and Environment, Inc. in 1997. The method combines the use of colorimetric gas detector tubes (originally designed for occupational breathing-zone monitoring) with sample purging to detect very low (ppb-range) concentrations of chlorinated compounds in groundwater and soil samples. Please contact Perry Kelso at PKelso@ene.com for more information. |
| Considerations Regarding Application of Permanganate for Remedies in Tennessee (PDF) (51K/11pp) |
The purpose of this document is to educate regulators and
project managers about the DNAPL problem and to spotlight a selection of
emerging characterization and remediation technologies for DNAPLs.

| Enhanced Reductive Dechlorination and the Relationship Between
CIS-1,2-DCE Accumulation and Methanogenesis (PDF) (103K/11pp) |
| Enhanced reductive dechlorination is a viable technology for treating chlorinated ethenes whether implemented through the addition of Hydrogen Releasing Compound (HRCTM), molasses, sodium lactate, vegetable oil, or other organic carbon sources. However, no technology works equally well at every site, and it is important to understand the complexities of the local microbial community. This paper, by the Florida Department of Environmental Protection and Geosyntec, describes a problem that appears relatively common at sites undergoing enhanced reductive dechlorination, the accumulation of cis-1,2-dichloroethene (cis-1,2-DCE). In addition, this paper provides a cost analysis of this treatment technology. |

| Reported Leaks, Spills and Discharges at Florida Drycleaning Sites (PDF) (92K/14pp) |
| This paper presents data collected by the Florida Drycleaning Solvent Cleanup Program on reported spills, leaks and discharges of drycleaning solvent and solvent-contaminated wastes at 334 drycleaning facilities and 14 drycleaning wholesale supply facilities located in Florida. This information will be useful to those conducting contamination assessments and soil and groundwater remediation at contaminated drycleaning sites by helping to identify contaminant source areas. Since the bulk of the contaminant mass is generally located in close proximity to the discharge point, a better understanding of drycleaning equipment, operations and waste management practices, particularly former industry practices, will facilitate identification of contaminant source areas. This will enable investigators to focus sampling during site assessment activities to provide a more accurate picture of contaminant mass distribution in contaminant source areas that is necessary for successful site remediation. Information contained in this paper may also be useful to regulatory personnel conducting compliance inspections at drycleaning operations. |
