ELIZABETH WRATTEN | LG

Overview

Elizabeth Wratten (Lizzie) joined the RGI team as a summer intern in 2017. At the conclusion of her three-month internship Lizzie continued to work at RGI part-time until she later became a full-time staff geologist in June 2018. Lizzie utilizes her applied geology background to expertly analyze the landscape and materials uncovered during explorations. On site during explorations (often test pits and borings), Lizzie logs soils, identifies water levels and soil densities, and collects samples to transport back to RGI’s laboratory. Lizzie’s lab work includes testing samples for moisture, sieve, proctor, and Atterburg Limit information. After compiling the data gathered during explorations and laboratory analysis, Lizzie assesses the subgrade of each site and synthesizes her findings into comprehensive Geotechnical Engineering Reports for her clients.

Lizzie works closely with the geotechnical department performing geotechnical construction monitoring, soil compaction testing, pile installation monitoring, foundation/footing observations, and water monitoring. On site water monitoring includes turbidity, pH, and settleable solids tests. As a certified erosion and sediment control lead, Lizzie records onsite observations of all materials leaving the site as well as locations where sediment could escape the site. Her observations allow the owner and site contractor to establish temporary erosion control measure to keep all soils and water on the site, helping protect the surrounding environment.

In 2022, Lizzie began working with RGI’s hydrogeologic department lead, David Baumgarten. Lizzie has successfully run both small and large pilot infiltration tests (PITs) throughout the Puget Sound to assess soil infiltration rates. She has overseen the installation of ground water monitoring wells and observed water levels over the wet winter season to assess high ground water levels for planning purposes. Lizzie has also conducted slug testing in wells to provide hydrogeologic variables. She then utilizes MODFLOW software to perform mounding analysis of sites with the collected hydrogeologic statistics.
