California Code of Regulations › Title 22 - Social Security › Division 4.5 - Environmental Health Standards for the Management of Hazardous Waste › Chapter 15 - Interim Status Standards for Owners and Operators of Hazardous Waste Transfer, Treatment, Storage, and Disposal Facilities › Appendix VI - Suggested Detection Monitoring Analytes

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
This list is intended as a guide to owners or operators of
				  treatment, storage and disposal facilities, and to enforcement and permit
				  granting officials, to assist in the selection of appropriate monitoring
				  parameters for specification in the water quality sampling and analysis plan.
				  The Department is not requiring that all facilities use this list, but the
				  Department believes that these are the best leak indicators for the majority of
				  units, especially if the unit contains a variety of wastes. This list is called
				  Leak Detection Analytes and is made up of volatile organics, hazardous metals
				  and pH (hydrogen ion).
Investigations by USEPA's Environmental Monitoring Systems
				  Laboratory in Las Vegas, Nevada, and others, have shown that most (as high as
				  70 percent) of the compounds leaking from RCRA sites are volatile organics.
				  This preponderance of volatiles is not surprising since these compounds would
				  be more likely to move quickly and easily through the environment given their
				  volatility. Therefore, it is logical to conclude that volatile organics would
				  be among the best indicators for early detection of a release.
The rest of the Leak Detection Analytes list is made up of
				  those metals that are amenable to the basic inductively coupled plasma (icp)
				  scan and pH. The metals were chosen because they make up the second most common
				  group of substances that leak from hazardous waste land disposal units, and
				  therefore, are also expected to be excellent leak indicators. pH was chosen
				  because of its all around utility in environmental monitoring and data
				  interpretation. pH was also chosen because of its ability to indicate leaks
				  that otherwise might not be indicated because no single substance has exceeded
				  a detectable level.
