Treatability studies samples

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 ... 

Exclusions for laboratory samples and waste treatability studies... 

Plants are harvested one to two weeks after the final amendment application, depending on weather conditions and the physiological condition of the crop. The plant stems are cut at the soil surface. Representative plant samples are taken for laboratory analysis and treatability studies for evaluation of the phytoextraction.The remaining biomass is collected and removed from the site for further processing. 

AS Treatability and Environmental Concentrations. Studies of AS degradation in the environment or during actual sewage treatment have been limited because specific analytical methods to measure AS were not available until recently. We developed a method that isolated AS from water samples on a strong anion-exchange column. The AS were then hydrolyzed to a fatty acid and analyzed by gas chromatography with flame-ionization detection (GC-FID). The method has a detection limit of 5 xg/L per component (50).
