Among the instrumental techniques, GC and GC/MS are most suitable for its analysis. Air analysis is performed by absorbing it over coconut shell charcoal, desorbing the analyte into carbon disulfide containing 2% acetone and injecting the eluant into GC equipped with FID (NIOSH 1984, Method 1604) 20% SP-1000 on 80/100-mesh Supelcoport or any equivalent column is suitable for the purpose. Analysis of acrylonitrile in wastewaters may be performed by GC-FID using Method 603 or by GC/MS Method 624 (U.S. EPA1990). U.S. EPA Method 8240 (1997) describes soil and hazardous wastes analysis by GC/MS technique. The primary characteristic ion is 53.

The EPA Contract Laboratory Program (CLP) has responsibility for managing the analysis programs required under the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The approved analytical methods are designed to analyze water, soil, and sediment from potentially hazardous waste sites to determine the presence or absence of certain environmentally harmful organic compounds. The methods described here all require the use of GC/MS. 

At the Taylor Road landfill (originally intended for the disposal of municipal refuse only), unknown quantities of hazardous wastes from industrial and residential sources were deposited. During the period when the landfill was active, soil and groundwater samples collected at the site were found to contain concentrations of volatile organic compounds and metals above acceptable safe drinking water standards. Analysis of samples collected from private drinking water wells indicated that contamination... 

HAZWOPER applies only where exposure to hazardous substanees or to health and safety hazards resulting from a hazardous waste operation is likely (see Eigure 2-1). This ean be determined by analysis of exposure monitoring data, hazard eharaeterization, hazard analysis, or exposure assessment [1]. Some of the speeifle examples of work aetivi-ties and situations will be eovered later.

The design of this fish study centered on sample collection, preservation, preparation, analysis, and QA/QC. There was no discussion of the effect of compositing on the sample population. No description was given of statistical techniques to be applied to the data for reporting results and for comparison with action levels and future data. Unfortunately, the omission of a statistical framework during planning of the field study is the rule rather than the exception in hazardous waste investigations. 

The hydrogeological and QA/QC aspects of hazardous waste field investigations are fairly well advanced. Yet needed, however, is a systematic approach to the design of field sampling, to the selection of compounds for analysis, and to the methods for interpretation of analytical data. 

Because hazardous waste combustion units are a type of TSDF, they are subject to the general TSDF standards in addition to combustion unit performance standards and operating requirements. Combustion units are also subject to specific waste analysis, inspection and monitoring, and residue management requirements. 

Hazardous waste samples are small, discrete amounts of hazardous waste that are essential to ensure accurate characterization and proper hazardous waste treatment. In order to facilitate the analysis of these materials, RCRA exempts characterization samples and treatability study samples from Subtitle C hazardous waste regulation ... 

All devices classified as incinerators that burn hazardous waste must follow the Subpart O standards, with the following exception. The Regional Administrator must exempt an owner/operator applying for a permit from all of the incinerator standards in Subpart O, except waste analysis and closure, if the hazardous waste fed into an incinerator is considered as low-risk waste. The criteria for defining a waste as low risk are as follows4 ... 

The posttrial bum period is the time for U.S. EPA to evaluate all of the data that were recorded during the incinerator s trial burn. To allow the operation of a hazardous waste incinerator following the completion of the trial bum, U.S. EPA establishes permit conditions sufficient to ensure that the unit will meet the incinerator performance standards. This posttrial burn period is limited to the minimum time required to complete the sampling, analysis, data computation of trial bum results, and the submission of these results to U.S. EPA. 

During operation, the owner/operator of an incinerator must conduct sufficient waste analyses to verify that the waste feed is within the physical and chemical composition limits specified in the permit. This analysis may include a determination of a waste s heat value, viscosity, and content of hazardous constituents, including POHCs. Waste analysis also comprises part of the trial burn permit application. U.S. EPA stresses the importance of proper waste analysis to ensure compliance with emission limits.
