Beaverdam Road Landfill Permeable Reactive Barrier

The Beaverdam Road Landfill (BDRLF) site is another site BMT characterized for the U.S.

The Beaverdam Road Landfill (BDRLF) site is another site BMT characterized for the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) at the Beltsville Agricultural Research Center (BARC) in Maryland.

BMT led a Remedial Investigation/Feasibility Study that included site investigation, development of a Site Screening Process, ecological risk assessment, human health risk assessment, and feasibility study to evaluate remedial options.

BMT completed soil, surface water, sediment, and groundwater sampling. Groundwater samples were collected with Geoprobe® direct push wells. The selected remedy was the installation of a permeable reactive barrier (PRB) to create the conditions necessary for the microbially mediated degradation of trichloroethene in groundwater.

PRBs are a developing remediation technology which employs an underground structure to host a bio-film membrane to capture and break down contaminants as they pass through the wall. Treated groundwater is passively discharged via natural groundwater flow.

BMT completed a comprehensive Remedial Design/Remedial Action Work Plan which was approved EPA Region III. BMT performed routine monitoring to evaluate PRB performance and achievement of applicable or relevant and appropriate requirements developed during the remedial investigation and feasibility study.

College Park Landfill Pilot Study

BMT conducted a Pilot Study of the College Park Landfill (CPLF), a 30-acre site operated as a municipal landfill from 1954 through 1978. Following closure, a cover was applied, but it was not closed in accordance with regulatory requirements. As landfills are known for their ability to mobilize hazardous substances into surrounding media, the CPLF was added to the U.S. Superfund (CERCLA) program for further evaluation.

Abrolhos Islands Aquaculture Modelling

BMT developed a 3D hydrodynamic and water quality model of the region around the Abrolhos Islands in Western Australia. In collaboration with BMT and the University of Western Australia, model results were used to assess the impact of proposed finfish aquaculture on the surrounding environment.

Arabian Gulf Aquaculture Feasibility Analysis

BMT was commissioned by the Abu Dhabi Environment Agency to undertake advanced numerical modelling at a site within the Arabian Gulf. This was to assess the viability of developing aquaculture operations at the site.

Assessing Climate Change Vulnerability of Seqwater Built Assets (2020)

Seqwater is the Queensland Government Bulk Water Supply Authority and manages over $11 billion of water supply infrastructure - including dams and weirs, conventional water treatment plants, a desalination plant, the Western Corridor Recycled Water Scheme, as well reservoirs, pump stations and more than 600 kilometres of bi-directional pipeline network. As part of Seqwater's climate change risk management, this project undertaken by BMT assessed climate change vulnerability of Seqwater's built assets.
