Constandina Apergis Presented on Groundwater Geology at Fort Lewis College

Constandina "Coco" Apergis (Colorado) presented on groundwater geology to a class at her undergrad alma mater, Fort Lewis College, in Durango, Colorado on November 8, 2019, as part of the Denver branch's outreach efforts under the Colorado Environmental Leadership Program (CO ELP). 

Coco is a Staff Scientist based in Colorado with a focus on environmental consulting. Her other areas of concentration are acid mine drainage processes and passive remediation technologies. She has additional experience with sustainability/environmental, social and governance (ESG) benchmarking and gap analyses, geographic information systems (GIS), field research, environmental sampling, field mapping, modular three-dimensional dinite-difference groundwater flow model (MODFLOW), and presenting findings.

The CO ELP is a statewide environmental recognition and reward program for members that voluntarily go beyond compliance with state and federal regulations and are committed to environmental improvement. This presentation will contribute to the Corporate Social Responsibility section of the ELP annual report for the Denver branch.

The presentation included descriptions of indoor air sampling techniques to monitor for vapor intrusion, pump and treat systems, and bailing and low flow groundwater sampling techniques. The students were then involved in a hands-on exercise where they filled up volatile organic compounds (VOC) sample bottles from a bailer of water, trying to properly collect a sample (i.e., without any air bubbles). The course professor was excited and grateful Coco was able to come and speak to the class, sharing "real-world" experience with undergraduate geology students.
