Ulf Lindmark has been active in the environmental field since 1980. He has specialized knowledge in both the theoretical and practical aspects of environmental engineering, particularly in the areas of remedial action design, water treatment, contamination transport, hydrogeology, construction management, and agency requirements.

Ulf has extensive experience in assessment and remediation of sites containing gasoline and associated compounds such as MTBE, TBA and benzene; PCE, TCE, and other chlorinated hydrocarbons; diesel; waste oil; crude oil; pesticides; PCBs; PNAs (poly-nuclear aromatics); acids; alkalines; brine; and heavy metals. His experience includes a variety of sites, such as chemical plants, construction sites, dry cleaners, fueling facilities, hospitals, landfills, manufacturing facilities, office buildings, oil fields, plating shops, salvage yards, schools, and service stations.
