Assisted the client in gaining regulator’s approval of a proposed remedy modification based on site constraints.

Dust Monitoring Study, Hawai‘i — Designed and coordinated sampling activities to assess airborne fugitive dust concentrations at various farms across the State of Hawai‘i.  Used air sampling pumps and portable TSI Dust Trak™ units to generate real-time, continuous dust concentration readings for various particle sizes.  The study documented correlations of dust with human activities and with meteorological conditions.

Background Metal Study, Hawaiian Islands — Conducted a study for the Hawai‘i Department of Health to identify background concentrations of metals in Hawaiian soils; findings were intended for use in setting action levels.  Reviewed and statistically analyzed published data to establish upper thresholds in metal concentrations.  Designed and implemented a soil sampling plan, and collected soil samples across the Hawaiian Islands.

Phase I and II Environmental Site Assessments, Hawai‘i, Continental U.S., Canada, and Europe — Coordinated Phase I and II environmental site assessments in support of real estate transactions involving commercial and industrial properties, and portfolios of commercial properties for the car rental industry. Phase II site assessments involved soil, groundwater, and air testing.
