The Federal Facilities Forum is a group of It is imperative that any persons working U.S. Environmental Protection Agency on sites believed to be contaminated with (EPA) scientists and engineers, representing explosive residues thoroughly familiarize EPA regional offices, committed to the themselves with the physical and toxic identification and resolution of issues affectproperties of the mate...

The term bioremediation covers a wide variety of engineered systems which utilize microorganisms to degrade, detoxify and immobilize organic contaminants. These systems include: l solid-phase treatment using unlined iand treatment systems or prepared bed bioreactors, l slurry-phase treatment systems completed either in-place or within tanks or impoundments, and l in situ treatment systems. Bior...

Waste molding sands from the foundry industry have been successfully used as a component in manufactured soils, but concern over metal contamination must be addressed before many states will consider this beneficial use. Since there is little data available on this topic, the purpose of this study was to characterize total and leachable metals from waste molding sands. A total elemental analysi...

A major contributor to atmospheric and ground water pollution is caused by fuel hydrocarbons. These problems can often occur through accidental emission during storage or use. Out of the millions of underground fuel storage tanks that are in place throughout the country many are leaking and many more are destined to produce leaks at some future date. The problem is serious enough that under the...

Heavy metals contamination can be found at battery acid recycling sites, electroplating facilities, military installations, firing ranges, brownfields redevelopment sites, and associated with mining activities. The chemical stabilization process uses non-hazardous chemical binders that permanently stabilize heavy metals. The treated soils contain stable metalreagent compounds that eliminate the...

A one-year survey was conducted in the greater region of Crete (located at the lower region of the Aegean Sea) for the purpose of identifying waste composition (including chemical and physical characterization), as well as any seasonal variation. The investigation was carried out repeatedly at seven landfills and one transfer station in Crete, in four phases. Each sampling phase corresponded to...

During the past several years, waste produced by the electroplating industry has attracted attention due to the level of pollutants found in the waste stream, the difficulty associated with treatment, and the cost of waste disposal. EPA has enacted regulations to control the discharge from plating facilities and estimates that 140 million lb of metal pollutants will be prevented from being disc...

Introduction The current regulatory climate is causing both large and small companies to reconsider their existing cleaning methods. The use of chlorinated solvents in metal and electronics parts cleaning is no longer the primary method of choice. Over the last five to 10 years, the consequences of past usage of these cleaning systems have led to traumatic and expensive experiences of many comp...
