Well Installation Support, Crown Resources Corporation, Chesaw, WA. Geologist.
Sited well locations, logged borehole lithology, oversaw well construction and development
of a piezometer and a mine dewatering well, and wrote technical memorandum of drilling
activities. Created health and safety plans for expected work. This project involved the
installation of a piezometer to monitor ground water along a fault zone. It also involved
installation of a injection well that will be used to pump treated mine water from the on-site
water treatment plant back into the mine water system.

Settlement Evaluation, Confidential Client, Seattle, WA. Hydrogeologist. Compiled and
analyzed water level, pumping, geologic, and geophysical data to evaluate settlement
damage claims. This project involved our professional assessment of the claims to assist the
client in an ongoing litigation.

I-5 Expansion Support, Parametrix Inc./Washington State Department of
Transportation, Lakewood, WA. Hydrogeologist. Conducted large-scale pit infiltration
testing, assisted with on-site water treatment plant operations, and assisted in data analysis
and report writing. This project involved field data collection to support the design of the I-5
widening project near the Berkeley Avenue interchange.
Settlement Evaluation, Confidential Client, Redmond, WA. Hydrogeologist. Analyzed
seasonal water level data and construction blue prints to evaluate settlement damage claims.
Pioneer Park, HDR Engineering Inc., Tumwater, WA. Hydrogeologist. Conducted slug
test analysis of multiple wells and generated a technical memorandum of results. This
project involved further geotechnical and hydrologic evaluation of a proposed fish hatchery
facility located adjacent to a river channel.
Interceptor Trench Extension, Reserve Silica Corporation, Ravensdale, WA.
Hydrogeologist. Conducted rising head tests and performed initial analysis to estimate
hydraulic properties. This project involved an estimation of aquifer properties that will assist
in the future alignment and design of a trench with the purpose of diverting contaminated
ground water toward the on-site water treatment plant that is located downgradient.
Superfund Site, Confidential Client, Burbank, CA. Hydrogeologist. Sited well locations,
logged borehole lithology, and oversaw well construction and development of two
monitoring wells. Conducted field data collection activities, managed on-site waste disposal
operations, assisted with on-site treatment plant operations, and installed data loggers. This
project involved evaluating contamination transport and ongoing clean-up of the aquifer to
assist client to meet regulatory requirement and assist them in an ongoing litigation.
Superfund Site, Confidential Client, Soda Springs, ID. Hydrogeologist. Created report
graphics and assisted with data analysis that was included in a remedial investigation report
delivered to multiple regulatory agencies.

Superfund Site, Confidential Client, Soda Springs, ID. Geologist. Conducted soil and
sediment collection activities. This project involved field data collection to assist the client
meet regulatory requirements.
Cadman High Rock Quarry Expansion Support, Cadman Inc., Monroe, WA.
Hydrogeologist. Sited well locations, logged borehole lithology, and oversaw well
construction and development of ten monitoring wells of variable lengths. Conducted field
data collection activities, installed data loggers, trained field staff, and interacted with
stakeholders and the client. This project involved evaluating the ground water system to
ensure the planned Quarry expansion doesn’t affect the aquifer that stakeholders actively use
as their drinking water source. It also involved data collection for use in the engineered
design of the expansion area infiltration pond.
