Profile Picture

Mary Sands has more than three decades of experience as an environmental consultant including brownfields investigation and remediation, all phases of environmental due diligence, multi-media compliance audits, and cost engineering for environmental liability assessment. Her clients have included attorneys, developers, corporate real-estate managers, Native American tribes, universities, and others associated with property development. Mary has managed the investigation of numerous sites with hazardous-substance, petroleum, and agricultural contamination in the soil and groundwater. A number of these sites were enrolled in the Minnesota Pollution Control Agency’s Voluntary Investigation and Cleanup Program and Petroleum Brownfields Program, as well as the Minnesota Department of Agriculture’s Agricultural Voluntary Investigation and Cleanup Program. For many of these sites, soil and groundwater remediation (consisting of soil-vapor extraction, air sparging, excavation, dual-phase extraction, land farming, or capping) has been performed.
