SW-846 Test Method 0010: Modified Method 5 Sampling Train

This method is applicable to the determination of Destruction and Removal Efficiency (DRE) of semivolatile Principal Organic Hazardous Compounds (POHCs) from incineration systems (PHS, 1967).

SW-846 Test Method 0011: Sampling for Selected Aldehyde and Ketone Emissions from Stationary Sources

This method is applicable to the determination of Destruction and Removal Efficiency (DRE) of the analytes listed in a table within the method.

SW-846 Test Method 0020: Source Assessment Sampling System (SASS)

This method is applicable to the preparation of semiquantitative estimates (within a factor of three) of the amounts and types of semivolatile organic and particulate materials that are discharged from incineration systems.

SW-846 Test Method 0023A: Sampling Method for Polychlorinated Dibenzo-p-Dioxin and Polychlorinated Dibenzofuran Emission From Stationary Sources

This method describes the sampling procedure to be used for determining stack emissions of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) from stationary sources.

SW-846 Test Method 0051: Midget Impinger HCl/Cl2 Emission Sampling Train

This method describes the collection of hydrogen chloride (HCl, CAS Registry Number 7647-01-0) and chlorine (Cl2, CAS Registry Number 7782-50-5) in stack gas emission samples from hazardous waste incinerators and municipal waste combustors.

Causal Analysis/Diagnosis Decision Information System (CADDIS)

The Causal Analysis/Diagnosis Decision Information System, or CADDIS, is a website developed to help scientists and engineers in the Regions, States, and Tribes conduct causal assessments in aquatic systems to determine the cause of contamination.

SHAMANTRA GREEN

Technical product bulletin: this bioremediation agent (nutrient additive) used in cleanups is recommended on water and near shoreline oil spills. It is a natural product made using humic acid.
