<br /> (1)TITLE AND LOCATION(City and State) (2)YEAR COMPLETED
<br /> Hydrogeologic Study to Detect Impact of MILCON P-184 PROFESSIONAL SERVICES CONSTRUCTION(If applicable)
<br /> Reject Water,Diego Garcia,British Indian Ocean Territory 2016 -
<br /> (3)BRIEF DESCRIPTION(Brief scope,size,cost,etc.)AND SPECIFIC ROLE E Check if project performed with current firm
<br /> E2 conducted a hydrogeologic study to evaluate the potential impacts to the water supply aquifer in the
<br /> Cantonment Area on Diego Garcia resulting from the disposal of reject water created by the recently
<br /> constructed nanofiltration water treatment plant. A temporary injection well was installed roughly 100 feet
<br /> a. south of the nanofiltration plant recharge field. A network of 35 nested piezometers was installed in the
<br /> vicinity of the temporary injection point and a nine-hour duration injection test was conducted using brackish
<br /> water spiked with a bromide tracer. The monitoring data collected during this injection test along with a pump
<br /> test conducted on a nearby water supply well was used to calibrate 2D/3D density dependent groundwater
<br /> models (SEAWAT) that were used to evaluate the potential for the injected concentrate from the nanofiltration
<br /> plant to impact the water quality in the nearby water supply wells located inland of the recharge field within
<br /> the Cantonment Area. Fee: $476,304. Role: Project Manager/Senior Hydrogeologist.
<br /> (1)TITLE AND LOCATION(City and State) (2)YEAR COMPLETED
<br /> Kanaha Pond Wildlife Sanctuary Hydrogeologic Study, PROFESSIONAL SERVICES CONSTRUCTION(If applicable)
<br /> Kahului,Maui,Hawaii 2010 -
<br /> (3)BRIEF DESCRIPTION(Brief scope,size,cost,etc.)AND SPECIFIC ROLE E Check if project performed with current firm
<br /> b. E2 conducted a 10-month long hydrogeological investigation to quantify the seasonal relationships between
<br /> the various inputs and outputs to the ponds in the refuge. Monitoring included installation of nested
<br /> piezometers, a meteorological station, tidal gauging stations, and automated rainfall gauges, and the collection
<br /> of sediment cores. Fee: $92,000. Role: Senior Hydrogeologist.
<br /> (1)TITLE AND LOCATION(City and State) (2)YEAR COMPLETED
<br /> Proposed Seawater Desalination Facility Project,Kalaeloa, PROFESSIONAL SERVICES CONSTRUCTION(If applicable)
<br /> Oahu,Hawaii 2018 -
<br /> (3)BRIEF DESCRIPTION(Brief scope,size,cost,etc.)AND SPECIFIC ROLE E Check if project performed with current firm
<br /> Principal investigator for a large-scale pump test conducted on a 1,600-foot deep basaltic well located in
<br /> Kalaeloa proposed for use in a desalination project for the Honolulu Board of Water Supply.The deep well was
<br /> pumped for three consecutive days at pump rates of between 520 to 540 gallons per minute and the pumped
<br /> c. water was injected into a nearby injection well that was screened 300 feet into the underlying caprock aquifer.
<br /> Water quality measurements were made throughout the duration of the pump test for temperature,
<br /> conductivity, turbidity, pH, oxygen reducing potential, dissolved oxygen, and silt density index. The drawdown
<br /> and tidal efficiency of the basaltic well was determined by installing a CDT probe in the pumping well while the
<br /> efficiency of the caprock injection well was determined using a pressure transducer. A total of six water
<br /> samples were collected during the duration of the pump test and submitted for analysis for all drinking water
<br /> constituents including those listed in Appendix A of HAR Chapter 11-20 as well as secondary standards defined
<br /> by the US Environmental Protection Agency.Role: Senior Hydrogeologist.
