Summary: State based policy and standards for PFAS and Emerging Contaminants are evolving quickly and can have a significant effect on your project or business. Sigma’s presentation outlines the technical and regulatory conditions surrounding this moving target.
Presented at the Clean Rivers Clean Lakes Conference, 2013 and Wisconsin Green Building Alliance, 2013
Summary: This presentation summarizes the planning and sustainable design efforts implemented at the Reed Street Yards – Global Water Technology Park, an evolving eco-industrial zone, designed by The Sigma Group, Inc. and partners for the development team of General Capital Group and Peter Moede.
The project incorporates sustainable design features that include an extension of the Hank Aaron State Trail along the South Menomonee Canal, purple pipe for recycled and reclaimed water reuse; porous pavement; landscape architecture utilizing the native plant palette of the Menomonee Valley estuary, innovative bio-swales for stormwater treatment, and the use of a self-contained, water treatment system integrated into a spectacular water feature, the visual focal point of the Technology Park.
Industrial Wastewater Treatment Operators Training for Metal Finishing, Molding and Casting, Federation of Environmental Technologists, 1994-2006
Summary: This presentation is the first full day of instruction in a five-day class presented annually by the Federation of Environmental Technologists focusing on the management of industrial wastewater containing metals, organic compounds, and oils. Topics covered in this session include a regulatory overview of pertinent water regulations, basic problem solving, an introduction to industrial wastewater treatment, pH control, oxidation-reduction processes, and metals precipitin. The course prepares industrial wastewater treatment operators who are taking the Wisconsin Department of Natural Resources certification test, as well as satisfying professional development CEU credits.
Certified Hazardous Materials Managers-Wisconsin FET Chapter, Regulatory Overview course, 2000-2006.
Summary: This presentation is one of 12 sessions presented annually by the CHMM-Wisconsin FET Chapter that prepares participants who are taking the CHMM certification examination. Topics covered in this session include a survey of various treatment unit processes such as filtration, sedimentation, oxidation/reduction, thermal destruction and biological treatment and the usefulness of environmental sampling.
As an alternative to more traditional stormwater management approaches which rely on above ground detention basins, Sigma designed an innovative stormwater management system for an approximate 1.23-acre commercial development in Oak Creek, Wisconsin. The system utilizes previous concrete pavement and an underlying stone detention bed for management of stormwater at the site. The system results in zero discharge of stormwater from the site and eliminated the need for additional land to accommodate traditional above ground stormwater detention basins.
