Programmatic Sampling and Analysis Plan Project Number:60657245 <br /> 7. Disposal of Residual Materials <br /> In the process of collecting environmental samples, the sampling team will generate different <br /> types of potentially contaminated investigation-derived waste (IDW)that includes the following: <br /> • Used PPE <br /> • Disposable sampling equipment <br /> • Decontamination fluids <br /> • Soil cuttings from soil borings <br /> Soil cuttings generated during the subsurface sampling will be disposed of in an appropriate <br /> manner. <br /> Used PPE and disposable equipment will be double bagged and placed in a municipal refuse <br /> dumpster. These wastes are not considered hazardous and can be sent to a municipal landfill. <br /> Any PPE and disposable equipment that is to be disposed of which can still be reused will be <br /> rendered inoperable before disposal in the refuse dumpster. <br /> Wash water from sampling equipment decontamination will be containerized in 55-gallon drums, <br /> and one sample from each drum will be analyzed for waste characterization purposes. Based <br /> on the results, the waste will be disposed of properly. AECOM assumes that the waste will be <br /> classified as non-hazardous. <br /> AECOM <br /> 16 <br />
