  4. P3 Funding For Green Infrastructure And How To Limit Risk 11/16/2021

    Public-Private Partnerships (P3) have been a popular funding mechanism for public works projects around the world since the late 1980s. More recently, P3 programs have been initiated to help address water quality concerns related to stormwater by providing funding for stormwater retrofits and the development of green infrastructure throughout a municipality, and has become a promoted method for funding these projects by the USEPA.   

  5. Understanding Public Perceptions And Demands Of Aquatic Resources Can Support Sustainable Management Practices 4/6/2021

    Surface waters – such as rivers, streams, lakes, reservoirs, estuaries, and coastal waters – are the primary types of aquatic resources that people interact with daily. As the global population continues to grow, demand increases for water resources. Scientists have long collaborated with government and local agencies to help manage these aquatic systems, and increasingly, researchers have been emphasizing the importance of treating our waterways as social-ecological systems. This view of systems recognizes the interconnected and resilient relationships between humans and nature. Understanding how individuals can positively interact and respond to water bodies over long periods of time would better support the sustainable management of aquatic resources.

    Crucial changes already underway, but significant challenges ahead, faculty say.

  7. Let's Work Together To Fix Regulatory Guidance 3/8/2021

    Responsible parties all want clean water and to abide by the rules that secure it, but what if the rules do more harm than good? With a recent Supreme Court decision on wastewater discharges and a change of presidential administrations as the backdrop, this op-ed from the National Ground Water Association addresses the conundrum.

  8. Flood Forecasting: The Original Operational Water Digital Twin 2/11/2021

    Flooding can be an essential part of the economy — so much agriculture depends on the nutrients that flood brings. However, most of us know flooding for the damage, disruption, and of course loss of life, that it brings.

  9. Pulp & Paper Wastewater Treatment - Innovative Treatment For Efficient Water Management 2/2/2021

    The paper and pulp industry is among the largest industrial users of water resources operating across the world. Typically, pulp and paper industry operations require on average about 54-70 m3 (18,000 gallons) of water per metric ton (2200 pounds) of processed paper goods. This water usage is staggering, and water is used in almost every single part of the pulp and paper manufacturing process. These paper mills produce significant quantities of both waste water and residual sludge waste from initial pulp digestion to pulp slurries, and washing the paper making machinery.

  10. Sustainable Wastewater Treatment & Reuse In The Age Of COVID-19 2/2/2021

    Due to vulnerability to water stress and drought conditions, commercial & industrial companies are taking control of their water management. This is accompanied by an increased investment in water recycling to reduce operational risk by focusing on sustainability wastewater treatment through decentralized recycling solutions.
