Project Summary for
Marpi Point Coastal Aquifer Investigation
Client: Asiana Airlines, Seoul Korea
Location: Saipan, Commonwealth of the Northern Mariana
Islands
Project Description:
AGS is conducting extensive hydrogeologic studies to provide
2,000,000 gallons per day of freshwater for two golf courses and
a hotel and condominium complex. The scope of work includes: well
 drilling;
saline aquifer profiling; extensive long term pumping test; ground
water tidal fluctuation monitoring; water quality analysis; geophysical
testing; hydrologic modeling; calculation of saltwater upconing
and permissible pumping rates; design of fresh water lens collection
tunnel system; salt water barrier well system design; ground water
recharge system. The primary problem was the thin freshwater lens
which was floating on saltwater. The contact was gradational and
the lens varied in thickness. AGS employed a variety of modeling
programs to evaluate and impacts of salt water intrusion, upconing
and for the evaluation of barrier techniques. The primary innovation
was the us of basal collection tunnel techniques to develop a
solution which was capable of producing the best quality water
without causing severe upconing problems.
