RISEPA 1315 One-Dimensional Leach Testing of Silts Impacted by Chlorobenzene-Rich NAPL
Publisher: ASCE
Abstract: An extensive treatability study was completed on a chlorobenzene-rich nonaqueous phase liquid (CB-NAPL) impacted source zone at an active industrial site. A baseline leaching condition for the low permeability silty site ...
Silica Fume Slurry Lagoon Closure: Thixotropic Material Characterization and Solidification
Publisher: American Society of Civil Engineers
Abstract: This paper reports on the evaluation and stabilization/solidification (S/S) of a thixotropic, silica-rich slurry sediment (SS) media from a 14.2-ha (35-acre) unlined lagoon that exhibited flash setting behavior when contacted ...
EPA LEAF Testing of Ultra-Lightweight Foamed Glass Aggregate to Support Vapor Barrier Applications on Ponds and Lagoons
Publisher: American Society of Civil Engineers
Abstract: Foamed glass aggregate (FGA) was characterized to evaluate its potential to serve as a vapor barrier on various water bodies [water supply reservoirs, industrial lagoons, acid mine drainage (AMD) ponds, etc.] Specifically, ...
EPA LEAF Testing of a Powdered Ladle Slag to Support pH Neutralization and Stabilization/Solidification Applications
Publisher: ASCE
Abstract: This paper reports on the characterization of a ladle slag from an electric arc furnace (EAF) steel mill that was pulverized to enable a wide range of beneficial uses that leverage its geochemistry and strong alkaline-buffering ...
Gowanus Canal Superfund Site. VII: Rapid Verification of Organoclay–Sand Capping Blends
Publisher: American Society of Civil Engineers
Abstract: At the Gowanus Canal Superfund site in Brooklyn, New York, a multilayer reactive capping system is required as part of the approved remedy. The base reactive layer is an organoclay (OC)–sand layer containing a minimum of ...
Herbicide-Impacted Sediment Remediation. II: Field Operations and Optimization

Gowanus Canal Superfund Site. I: NAPL Mobility Testing of MGP-Impacted Sediments
Publisher: American Society of Civil Engineers
Abstract: The Gowanus Canal superfund site is located in Brooklyn, New York. The site is impacted by nonaqueous phase liquid (NAPL) from historic manufactured gas plant (MGP) sites and other sources. One of the primary objectives ...
EPA LEAF Testing of Chlorobenzene-Impacted Sands and Soil–Cement Mix Designs
Publisher: ASCE
Abstract: This paper reports on laboratory-based treatability and field quality assurance (QA) testing completed on interbedded sands and silts at an industrial site heavily impacted by a chlorobenzene (CB)-rich nonaqueous phase ...
Gowanus Canal Superfund Site. V: Evaluation of ISS Cylinder Sample Crusts Formed During EPA 1315M Testing
Publisher: American Society of Civil Engineers
Abstract: The main purpose of treatability testing is to tailor a proposed remedial approach and related testing to site-specific conditions to ensure the maximum possible applicability of the bench-scale results at the full scale, ...
