United States Environmental Protection Agency EPA/600/N-94/013 October 1994 ECHNOLOGY RANSFER from Office of Research and Development Office of Science, Planning and Regulatory Evaluation New Technology Transfer Publications [use form in back to order] Alternative Methods for Delivery and Recovery (625/R-94/003) This manual presents informettion on alternatives to vertical wells for fluid recovery or delivery. Technologies described are horizontal wells, fracturing, and interceptor trenches. These technolo- gies, in certain settings, may be more appropriate than vertical wells for remedia- tion or gradient control. The manual will be of use to engineers, geologists, hydrogeologists, and scientists involved in ground water remediation or control. Information includes appropriate applica- tions, design considerations, and construc- tion methods. Several case studies are presented. Recycling and Reuse of Material Found on Superfund Sites (625/R-94/004) This manual encourages the recycling and reuse of materials found on sites. The National Contingency Plan (NCP) encour- ages recycling and reuse technologies. The manual will be useful to Superfund and Resource Conservation and Recovery Act (RCRA) waste treatment engineers and scientists since the EPA regional offices are reviewing Records of Decisions and Corrective Action Plans for these concepts. The manual provides informa- tion on the waste, process description, process maturity, advantages, disadvan- tages, and limitations for approximately 40 technologies. It contains a compendium matching a technology with waste types and a diagram containing recycling technologies for approximately 30 waste streams. The manual discusses product quality specification issues that must be addressed when reusing or recycling material from a contaminated site. The manual presents eight case studies using reuse and recycling of waste materials. Guide To Septage Treatment and Disposal (625/R-94/002) This guide presents information on the handling, treatment, and disposal of septage in a format easily used by administrators of waste management programs, septage haulers, and managers or operators of septage handling facilities. The guide does not provide detailed engineering design information. Septage is removed from a septic tank by pumping. This guide focuses on septage of domestic origin. Industrial septage containing toxic compounds or heavy metals requires special handling, treatment, and disposal methods, a description of which is beyond the scope of this document. Although some commercial septages may be appropriately treated with domestic septage, they must be evaluated on a case-by-case basis. When properly managed, domestic septage is a resource. A valuable soil conditioner, septage contains nutrients that can reduce reliance on chemical fertilizers for agriculture. A good septage manage- ment program maximizes the benefits of septage. This guide is divided into three parts. Part I: Administrators' Guide is a guide for managing the collection and treatment of septage. Chapters in Part I cover the following topics: Septage Handling Options (Chapter 2) Regulatory Requirements (Chapter 3) Local Responsibilities (Chapter 4) Part II: Inspectors' and Haulers' Guide is for those involved in inspecting septic tanks and in pumping and transport- ing septage. Chapters cover the following: Inspecting Septic Tanks (Chapter 5) Pumping. Septic Tanks (Chapter 6) Regulatory Requirements (Chapter 7) Printed on Recycled Paper ------- Part III: Facility Managers' and Operators' Guide provides information on operating and maintaining septage treatment and disposal facilities. Chapters cover the following: Septage Receiving (Chapter 8) Land Application (Chapter 9) Treatment at Wastewater Treatment Plants (Chapter 10) Independent Septage Treatment Facilities (Chapter 11) Odor Control (Chapter 12) Appendix A contains key references and information sources for detailed information on system design and opera- tion, federal regulations, and facility planning and management. Appendix B lists state and EPA regional septage coordinators. Appendix C gives an example of a beat permit for septage disposal. Although the information contained in Parts I, II, and III is targeted for the specific audiences described above, readers should review the entire guide to gain a broader understanding of the technical, administrative, and regulatory issues that a successful septage management program must address.

Since the ty btfftg tmptvwt , smdenhmcem&nt ysmg it to th lephone Design, Operation, and Closure of Municipal Solid Waste Landfills (625/R-94/008) This publication contains information given during seminars conducted during 1992. These seminars were conducted to assist municipal solid waste landfill owners and operators in addressing the require- ments in the RCRA Subtitle D regulations (40 CFR Part 258) published on October 9, 1991. This publication gives technical guid- ance on procedures for designing, constructing, operating and closing a municipal solid waste landfill. The docu- ment addresses landfill siting, landfill design criteria, landfill operations, ground- water monitoring, release characterization and remediation, closure and post-closure care, and financial assurance. This publication is for municipal solid waste landfill owners and operators, federal and state regulatory agency personnel, environmental consulting engineers, and other interested individuals. Organic Coating Replacements (625/R-94/OU6) This guide describes available and emerging cleaner technologies that can be used to reduce emissions and wastes from paint and coatings applications. Environ- mental concerns and increasing costs of organic chemicals and metals are leading to changes in the formulation of organic coatings that reduce or eliminate the use of volatile solvents, heavy metals, and the generation of hazardous paint residues and waste. This guide gives information in choosing cleaner technologies for further analysis and in-plant testing. It is intended for facilities in all segments of the paints and coatings industry including applicators of architectural coatings, finish coatings for parts and assemblies, and maintenance coatings. Although the guide discusses reformulations of paints and coatings, the primary focus is on applications. Process descriptions allow engineers to evaluate options for alternative coating materials or equipment that can be considered for existing facilities, and is useful for evaluat- ing opportunities for pollution prevention. Categories; of technologies discussed include high sblids coatings, powder coatings, waterborne coatings, elec- trodepositionjand ultraviolet/electronbeam radiation-cured coatings. Emerging technologies discussed include vapor injection cure coatings, supercritical carbon dioxide as a solvent, radiation induced thermally-cured coatings and emerging new paint formulations that will require further field testing. The pollution prevention strategy section discusses approaches to VOC reductions and presents an outline that allows the industry to examine specific emission coatings issues and form a plan to move to cleaner pollution prevention technologies. A list of trade associations is presented to assist in further follow-up on these technologies. Alternative Metal Finishes (625/R-94/007) This guide describes cleaner technolo- gies that can be used to reduce waste and emissions from metal finishing operations. All metal finishing processes generate wastes. This guide addresses processes using toxic or carcinogenic ingredients that are hard to destroy or stabilize and dispose of in an environmentally sound manner. This guide is valuable to metal finishing firms that use all types of metal finishes on both metallic and nonmetallic components, firms that use cadmium and chromium finishes, and finishers that use cyanide-based baths or copper/formalde- hyde solutions. This guide is organized into five sections. Sections One and Two discuss metal finishing and pollution prevention issues and identify processes that cause environmental concerns and serve as background to subsequent sections. Discussions of available and emerging cleaner technology alternatives are addressed in Sections Three and Four. Section Five is a strategy section that gives an overview for using cleaner technologies and addresses environmental concerns of metal finishing facilities. The available alternative technologies discussed in this guide include Non- Cyanide Copper Plating, Non-Cyanide Metal Stripping, Zinc/Zinc-Alloy Electro- plating, Blackhole Technology, Ion Vapor Deposition, Physical Vapor Deposition, Chromium-Free Aluminum Surface Treatments and Metal Spray Coating. Emerging technologies discussed include Nickel-Tungsten-Silicon Carbide, Nickel- Tungsten-Boron and In-Mold Plating. Information sources are also listed that identify various trade associations that can provide further technical details on these technologies as well as other types of information support to various segments of the metals finishing industry. ------- ORD BBS Update [Call 513-569-7610 to access the ORD Electronic Bulletin Board System] Bioremediation In the Field Search System (BFSS) BFSS is an information-sharing resource for federal and state regulators, consulting engineers, industry personnel, and re- searchers interested in the field application of bioremediation. It is a PC-based software product that provides access to a database of information on waste sites across the country where bioreme- diation is being tested, implemented, or has been completed. BFSS allows users to search the database electronically, view data on specific types of bioremediation sites, and print reports of selected information. BFSS currently provides electronic access to information on over 160 bioremediation sites nationwide. The database spans both full-scale remediation efforts and treatability and feasibility studies, and covers sites under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA); Resource Conservation and Recovery Act (RCRA); Toxic Substances Control Act (TSCA); and Underground Storage Tank (UST) authority. Data include the following: Location Region, state, and city or county Media Soil, surface and ground water, sediments, and sludge Contaminants Wood preserving wastes, petroleum, solvents, pesticides, and others Ex-situ and in-situ technologies Reactor treatments, aerated lagoon treatment, land treat- ment, composting, air sparging, and bioventing Cost and performance Capital and operation and maintenance costs, rate of contami- nant degradation, and lowest contaminant concentration achieved BFSS is available on EPA's Alternative Treatment Technology Information Clearinghouse (ATTIC) (703-908-2138), Cleanup Information (CLU-IN) (301-589-8366), and the ORD BBS.

The EPANET Water Quality Model EPANET is a software package developed by U.S. EPA's Drinking Water Research Division for modeling hydraulic and water quality behavior within water distribution systems. Starting with a geometric description of the pipe network, a set of initial conditions, estimates of water usage, and a set of rules for how the system is operated, EPANET predicts all flows, pressures, and water quality levels throughout the network during an extended period of operation. In addition to substance concentra- tion, water age and source tracing can also be simulated. EPANET offers a number of advanced features including the following: • modular, highly portable C language code with no preset limits on network size • a simple data input format based on a problem-oriented language • a full-featured hydraulic simulator • improved water quality algorithms • aneilysis of water quality reactions both within the bulk flow and at the pipe wall • an optional graphical user interface running under Microsoft Windows The Windows user interface allows one to edit EPANET input files, run a simulation, and view the results all within a single program. Simulation output can be visualized through the follow- ing: • color-coded maps of the distribution system with full zooming, panning, and labeling capabilities and a slider control to move forward or backward through time, • spreadsheet-like tables that can be searched for entries meeting a specified criterion, • time series graphs of both predicted and observed values for any variable at any location in the network. EPANET is currently being used to analyze a number of water quality issues in different distribution systems across the country. These include chlorine decay dynamics, raw water source blending, altered tank operation, and integration with real-time monitoring and control systems. Download the file EPANET.ZIP, unzip it, and print the README- file for instructions of how to install and run the pro- gram.
