Our multi-disciplinary Research Group specializes in civil, chemical and environmental engineering; microbiology; chemistry; and environmental sciences. Our services cover a variety of sectors in the wet infrastructure space that utilize water in their daily activities, such as wastewater disinfection, wastewater research, industrial water recycling, stormwater reuse, mining water, produced water and wastewater reclamation. The work we perform focuses on solving client-specific issues, conducting overarching research that serves a collaborative group of clients facing similar challenges, and supporting regulatory development at both the federal and state level. Our clients rely on our diverse experience and the high-quality performance data that our investigations generate to systematically evaluate the relative benefits of alternative solution strategies.

Developing Tools for Surface Water Nutrient Loading Attributable to Reclaimed Water, Florida, USA

In 2009, MWH, now part of Stantec, received a Tailored Collaboration grant from the WateReuse Research Foundation (WRRF), now WE&RF. In collaboration with several Florida utilities and management agencies, this funding supported the development of an empirical approach for distinguishing the contribution of water reuse irrigation toward nutrient impairment of surface waters in Florida. The Tailored Collaboration project, completed in 2012, identified the artificial sweetener sucralose (e.g. Splenda) as a marker unique to wastewater sources. As a result of this study, sucralose as a marker is being used by the Florida Department of Environmental Protection (FDEP) and other utilities nationwide.
