He has applied his expertise across a broad range of client sectors including chemicals and pharmaceuticals, large scale and speciality manufacturing, downstream oil and gas, and waste management. The main contaminant groups have been chlorinated solvents, other volatile and semi-volatile organic compounds, range of petroleum hydrocarbon products, heavy metals, trace metals and metalloids.
To help clients understand and prioritize programs to manage contaminated land and broader environmental liability issues, Marcus specializes in developing cost-effective, practical remedies using the latest proven technologies, as appropriate. He has served as the project director for many detailed, multi-phase, soil and groundwater investigation and remediation programs at sites across the UK & Ireland. These include groundwater plumes in fractured bedrock, potable water supply aquifers, discharging to inland waterways, and under housing and buildings with vapour intrusions risks. Over a ten year period he served as the project director and technical lead for the investigation and remediation of a chemical industry client portfolio of sites, including active and former chemical manufacturing sites and a chemical waste landfill.
In addition, Marcus leads projects involving property transactions (due diligence) and facility permitting/compliance. For example, he has served as the project director and lead consultant for more than 30 transaction-driven environmental due diligence assessments at industrial facilities and premises in the UK and Republic of Ireland. These have included relatively large and complex manufacturing installations such as pharmaceutical and chemical manufacturing plants.
