Overview Both natural and manmade fill materials are used for a variety of purposes. Fill material properties are commonly controlled to meet the necessary site spe- cific engineering specifications. Because most sites requiring fill material are located in or near urban areas, the fill materials are often obtained from con- struction projects that generate an excess of soil, and from demolition debris (asphalt, broken concrete, etc.). However, materials from those types of sites may or may not be appropriate, depending on the proposed use of the fill, and the quality of the as- sessment and/or mitigation measures, if necessary. Therefore, unless material from construction projects can be demonstrated to be free of contami- nation and/or appropriate for the proposed use, the use of that material as fill should be avoided. Selecting Fill Material In general, the fill source area should be located in nonindustrial areas, and not from sites undergoing an environmental cleanup. Nonindustrial sites in- clude those that were previously undeveloped, or used solely for residential or agricultural purposes. If the source is from an agricultural area, care should be taken to insure that the fill does not include former agricultural waste process byproducts such as manure or other decomposed organic material. Undesirable sources of fill material include indus- trial and/or commercial sites where hazardous ma - Potential Contaminants Based on the Fill Source Area Fill Source: Land near to an existing freeway Land near a mining area or rock quarry Agricultural land Residential/acceptable commercial land Target Compounds Lead (EPA methods 601013 or 7471 A), PAHs (EPA method 8310) Heavy Metals (EPA methods 601013 and 7471 A), asbestos (polarized light microscopy), pH Pesticides (Organochlorine Pesticides: EPA method 8081 A or 8080A; Organophospho- rus Pesticides: EPA method 8141 A; Chlori- nated Herbicides: EPA method 8151 A), heavy metals (EPA methods 6010B and 7471 A) VOCs (EPA method 8021 or 826013, as appropriate and combined with collection by EPA Method 5035), semi -VOCs (EPA method 8270C),TPH (modified EPA method 8015), PCBs (EPA method 8082 or 8080A), heavy metals including lead (EPA methods 601013 and 7471 A), asbestos (OSHA Method ID -191) *The recommended analyses should be performed in accordance with USEPA SW -846 methods (1996).
