accordance with a monitoring and reporting program order issued
by the Regional Water Quality Control Board (RWQCB), and development
of constituents of concern and a water quality protection standard.
The landfill gas compliance monitoring programs include sampling
14 soil gas monitoring probes, and 68 landfill gas vents for

compound emissions. H&A staff also developed and implemented
a detection monitoring program in accordance with Title 23,
