Landfill Groundwater and Surface Water Sampling and Analysis.
H&A
provides sampling and testing of groundwater and surface water
at the site, under order by the RWQCB to assess any degradation
of ground and surface water from a Class III landfill. Quarterly
groundwater sampling of 6 monitoring wells and surface water
runoff sampling at White Cabin Creek is performed in accordance
with the RWQCB monitoring and reporting program 95-161. Intra-well
comparisons are performed to evaluate groundwater quality as
specified in the monitoring and reporting program 95-161.
Additional
services provided to Glenn County include Storm Water Annual
Reporting, monitoring well assessments, abandonments, and installations.
Recent groundwater monitoring well installation activities utilized
ResonantSonic drilling technology capable of providing 4"
diameter continuous soil cores to a depth of 170 feet below ground
surface. Borehole geophysical logs were completed using
spontaneous
potential (SP), 16/64 normal resistivity, point resistance,
and natural gamma. Nested groundwater monitoring wells were
constructed to monitor the complex hydrogeological conditions
encountered beneath the landfill.
Through these services, Glenn County Landfill has been able to remain in full compliance with regulatory requirements and avoid penalties and fines.
