Comprehensive analysis of migration pathways (CAMP) : contaminant migration pathways at confined dredged material disposal facilities by James M Brannon( Book )

4 editions published in 1990 in English and held by 133 WorldCat member libraries worldwide

A confined disposal facility (CDF) is a diked enclosure having either permeable or low-permeable walls that are used to retain dredged material solids. There are two types of CDFs are located within the influence of normal tidal or other water fluctuations. This report identifies and documents key contaminant mobility processes and pathways operative in CDFs under varying operational and environmental conditions. It also summarizes what is known about contaminant migration, cycling, and mobilization pathways, provides information on models and assessment techniques, and identifies areas for which insufficient information is available. The present information does not permit evaluations of the relative significance of contaminant migration pathways from a CDF. Pathways involving movement of large masses of water, such as CDF effluent, leaching through permeable dikes, or leaching through the dredged material, have the greatest potential for moving significant quantities of contaminants out of the CDF. Pathways such as volatilization may also result in movement of substantial amounts of volatile organic contaminants from CDFs. The relative importance of contaminant cycling and mobilization pathways to net mass balance has not been determined, but available information on each of the contaminant migration, cycling, and mobilization pathways is summarized in the report. Where possible, methods have been provided for making rough estimates of contaminant mass movement via pathways. (TTL)

Leachate testing of Hamlet City Lake, North Carolina, sediment by James M Brannon( Book )

4 editions published in 1992 in English and held by 123 WorldCat member libraries worldwide

Sediment leaching studies of Hamlet City Lake, Hamlet, NC, were conducted in laboratories at the U.S. Army Engineer Waterways Experiment Station. The purpose of these studies was to provide quantitative information on the potential for leachate impacts on groundwaters if dredged material from Hamlet City Lake were placed in a confined disposal facility (CDF) or under disposal conditions similar to land-farming. The study involved three elements: batch leach tests, column leach tests, and simulations using the Hydrologic Evaluation of Landfill Performance (HELP) model. Batch tests were conducted to determine intrinsic leaching characteristics of solids in Hamlet City Lake sediment. Column tests were conducted as a physical analog of continuous flow leaching in a CDF. HELP model simulations were conducted to simulate the generation of leachate by infiltration and to evaluate the relative effectiveness of a disposal site liner. Results of this study showed that, under disposal conditions similar to land-farming, organic contaminants such as polycyclic aromatic hydrocarbons (PAHs) and total recoverable petroleum hydrocarbons (TRPHs) will decrease in concentration as the result of volatilization and or biodegradation

Evaluation of dredged material pollution potential by James M Brannon( Book )

7 editions published in 1978 in English and held by 46 WorldCat member libraries worldwide

This report synthesizes data from the U.S. Army Engineer Waterways Experiment Station, Dredged Material Research Program (DMRP), Task 1E. Task 1E consisted of seven research projects (work units) that investigated the pollution properties of dredged material and procedures for determining their potential for effect on water quality and aquatic organisms. The short-term impact of dredged material on water quality and aquatic organisms is related to the concentration of chemically mobile, readily available contaminants rather than the total concentration. The elutriate Test, which measures concentrations of contaminants released from dredged material, can be used to evaluate short-term impacts on water quality. Longer term impacts of dredged material on water quality have generally been slight and can be evaluated by means of the Elutriate Test and analysis of the mobile forms of sediment contaminants. No significant long-term increase in water column contaminant concentrations has been observed at any aquatic disposal field site. The greatest hazard of dredged material disposal is the potential effect of the material on benthic organisms. Most dredged material has not proven particularly toxic. Some dredged material has not proven particularly toxic. Some dredged material, however, can be extremely toxic or of unknown toxicological character. Benthic bioassay procedures are now available which can identify this toxic dredged material
Selective analytical partitioning of sediments to evaluate potential mobility of chemical constituents during dredging and disposal operations by James M Brannon( Book )

9 editions published in 1976 in English and held by 46 WorldCat member libraries worldwide

When sediments are agitated by dredging and subsequent resuspension in water by discharge operations, there is a possibility that large amounts of some chemicals in the sediment could be released into the water column. To better understand the short- and long-term release effects of sediment resuspension on water quality, a functionally derived sediment selective extraction procedure was developed. This procedure explores the association of trace metals and other elements or compounds within sediments and their distribution among sediment phases of various stability and mobility. The effect of these sediment fractions or extractable phases upon water quality as indicated by the standard elutriate test and the relation of elutriate concentrations to these fractions was thoroughly investigated. The sediment chemical partitions studied in the selective extraction procedure were those dissolved or in solution in sediment interstitial water; sorbed on sediment mineral and organic material (exchangeable); occluded, co-precipitated, or bound within iron and manganese oxide and hydroxide partitions; bound in organic matter as complexes and compounds precipitated as sulfide salts; and occurring as an extremely stable residual partition in mineral crystalline lattice. Results of the sediment partitioning fractionation scheme showed that these operationally or functionally defined phases in a sediment could be isolated with good elemental mass balance and precision among the phases
Long-term release of contaminants from dredged material : final report by James M Brannon( Book )

5 editions published in 1978 in English and held by 41 WorldCat member libraries worldwide

Man's activities in the Nation's coastal zones and waterways have served to contaminate sediments in these areas, generating concern that dredging and disposal may exert adverse effects on water quality and aquatic organisms. The long-term effects of dredged material on water quality at the disposal site remain an area of particular concern. To study the magnitude and predictability of long-term releases from dredged material, an 8-month aerobic leaching study was conducted in the laboratory. A large number of sediments (32) representing broad geographical and pollutional variation were used to ensure wide applicability of study results. Under the aerobic chemical conditions likely to prevail at aquatic disposal sites, total organic carbon, orthophosphate-P, and zinc exhibited the most consistent net releases to the water column. Very little net mass release of mercury (Hg), lead (Pb), cadmium (Cd), or arsenic (As) into the water column was observed regardless of the composition of the sediments. Worst case evaluation of the potential effects of contaminant releases, conducted by comparing results of this study with the most stringent water quality criteria available, indicated that sediments used in this study would not be expected to cause significant long-term water quality problems

Effectiveness of capping in isolating contaminated dredged material from biota and the overlying water by James M Brannon( Book )

4 editions published in 1985 in English and held by 33 WorldCat member libraries worldwide

The effectiveness of capping in chemically and biologically isolating contaminated dredged material was investigated using large- (250 pound) and small- (22.6 pound) scale laboratory reactor units. The ability of various cap materials to isolate contaminated dredged material was assessed in the large reactor units by following the movement of chemical contaminants and microbial spores contained in the capped dredged material into the overlying water column and by monitoring the biological uptake of chemical contaminants by clams and polychaetes. The depth of cap material needed to chemically isolate contaminated dredged material was assessed in the small-scale reactor units. Changes in overlying water concentrations of dissolved oxygen (DO), ammonium nitrogen manganese, and orthophosphate were monitored following isolation of the water column from air by placing a 4-cm layer of mineral oil on the surface. The constituents analyzed were selected due to their mobility under anaerobic conditions, ease of measurement, and generally high concentrations in contaminated dredged material compared to clean cap materials

Characterization of aerobic chemical processes in reservoirs : problem description and model formulation by Rex L Chen( Book )

7 editions published between 1981 and 1983 in English and held by 22 WorldCat member libraries worldwide

The occurrence of dissolved oxygen depletion and anaerobic processes in the hypolimnion of Corps of Engineers (CE) reservoirs can adversely impact water quality and directly affect CE Civil Works activities. A literature review, a consultation with authorities on anaerobic systems, and a workshop indicated the feasibility of developing a conceptual model to depict major pathways for nutrient regeneration and metal mobilization under anaerobic conditions. The product of subsequent model development and experimental studies, Dissolved Oxygen Subroutine with Anaerobic Processes (DOSAP), is presented herein and its operation is described in detail. The DOSAP model is presented as a series of seven linked geochemical steps (phases) of increasingly anaerobic (reduced) conditions. Major factors influencing the rate and duration of each of the major pathways are discussed. The DOSAP model has subsequently been transformed into a mathematical subroutine for the CE one-dimensional reservoir water quality model, CE-QUAL-R1. A literature search revealed a paucity of information on various physicochemical and biological rates affecting geochemical/water quality conditions in reservoirs, although abundant data for some parameters exist for other freshwater systems and marine environments
Laboratory studies of soil sorption/transformation of TNT, RDX, and HMX( Book )

3 editions published in 1998 in English and held by 21 WorldCat member libraries worldwide

Subsurface contamination by 2,4,6-trinitrotoluene (TM), 2,3,5-trinitro-1,3,5-triazine (RDX), and oxyhydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMx) is a problem at many military installations associated with munitions manufacturing, loading, assembling, and packing. To support Department of Defense remediation and containment goals, information on the processes affecting the subsurface transport of these explosives is needed. Specifically, information pertaining to sorption and transformation of these explosives is needed in order to facilitate numerical model development. This study provides complementary batch and column information on TNT and RDX sorption and transformation and column information on HMX sorption and transformation. Batch and column testing included soils with a wide range of physical properties, and attention was given to sterilized and unsterilized soils. One soil was common to both batch and column. Reductive transformation was established as an important process for TNT. Measurement of reductive transformation products provided definitive evidence of TNT transformation. Reductive transformation was also suspected for RDX and HMX, although RDX and HMX transformation products were not measured
