Abstract
In drought stricken areas such as the southwestern United States, where populations are
predicted to continue to increase significantly for decades to come, the scarcity of available
drinking water is an ever-growing threat. Today in California, heavy fees are imposed on
impacted groundwater that is extracted and not used as drinking water or restored and
reinjected into the aquifer. This session will present the current design and permitting
requirements associated with a 2,000 gallon per minute groundwater extraction and
treatment system (GETS) in California. The GETS will remediate several contaminants by
utilizing a complex interaction of treatment technologies including granular activated carbon
for VOCs, ion exchange resin for perchlorate, advanced oxidation for 1,4-dioxane and
reverse osmosis for treatment of total dissolved solids and selenium. In addition to cleaning
up impacted groundwater, the GETS will serve as a valuable new potable water supply that
will decrease the region’s reliance on imported water. Due to the site’s location and the end
use of the GETS, numerous local, state and federal permitting requirements are associated
with the system design, construction and operation of the system including permitting under
the California Division of Drinking Water’s 97-005 Policy. The extensive 97-005 permitting
process is required due to the end-use of the GETS as potable water.
This presentation will then discuss where and why drinking water end uses for impacted
groundwater are applicable to urban areas. It will touch upon what specific interests should
be considered with respect to reclaimed groundwater, whether state-specific regulatory
guidance should be developed and what we can learn from the associated policy
implemented by California.
