Landfill – Post-Closure Termination, Environmental Investigations, Monitoring, and Remediation Projects
Vashon Island Closed Landfill
Hobart Closed Landfill
The Vashon Island Closed Landfill is a 10.3-acre disposal site located on a 37.2-acre site and was closed in two phases between 1988 and 2001.
The Hobart Closed Landfill is a 35-acre disposal site contained within a 75-acre site and was closed in two-phases between 1990 and 1994. This landfill is unique as a slurry wall surrounds the landfill to separate the landfill from the shallow aquifer.
VIKEK, under contract with the prime consultant, is developing assessment methodologies and performance measurement metrics, completing data gap analysis, prioritizing assessments, and providing support for project management, environmental assessment, engineering design and implementation of improvements to the control systems necessary to achieve termination of post-closure activities at Vashon Island and Hobart Closed Landfills under the Washington Administrative Code (WAC).
Newmont Mine Wastewater Lagoon Liner and Floating Cover Assessment and Construction Quality Assurance Project
The Newmont Wastewater Ponds are double lined with a 60-mil, textured, high density polyethylene (HDPE) geomembrane with a geonet between the geomembranes to provide leak detection. The ponds were completed in 2019 for storage of mine – affected water for future treatment. It has two maintenance cells in the bottom known as the west cell and the east cell, each having a storage volume of approximately 3 million gallons.
In order to support the acquisition of regulatory permits, Vikek provided pond geomembrane integrity and leakage assessment and liner installation construction quality assurance services. Specific activities included evaluation of liner leakage mitigation options and construction observation.
OB-3 Wastewater Lagoon Floating Cover Assessment and Construction Quality Assurance Project
