SOURCE WATER CONTAMINATION RESOURCES

• Tackling Lake Erie's Algal Blooms Requires Targeted Conservation Strategies

  Algal blooms in Lake Erie remind us how closely food production and clean water are connected. Many of these nutrients come from nearby farms, and the challenge is keeping them out of waterways.

• After The Fire: What The 2026 Wildfires And El Niño Could Mean For U.S. Lakes And Reservoirs In 2027

  In July, smoke from Canadian wildfires spread across the upper Midwest and Northeast. Now a strengthening El Niño is set to influence the coming winter. Both events matter to lake and reservoir managers because their effects on water quality will continue to emerge long after the skies clear or the El Niño passes.

• Minneapolis Flexes Its Mussels For Source Water Monitoring Solution

  Protecting municipal drinking water requires rapid visibility into changing surface source conditions. Discover how combining biological indicators with continuous inline spectrometry delivers real-time contamination alerts, preventing costly treatment plant shutdowns and safeguarding consumer health.

• DEXSORB® Treatment At Groundwater Pump Station

  Discover how upgrading existing filter infrastructure with advanced adsorbent media provided over 600 days of continuous PFAS removal, treating millions of gallons of contaminated groundwater to achieve strict drinking water compliance.

• DEXSORB® Treatment Of Surface Water For Gravity System

  Discover how a dual-vessel lead-lag media system achieved continuous non-detect levels for target legacy contaminants, treating over 250,000 gallons of surface water to support regulatory compliance and municipal drinking water goals.

• Pretreatment Systems Enable Complete And More Economical PFAS Solutions For operators looking to optimize their PFAS removal systems, controlling the presence of dissolved organic carbon (DOC) offers an approach to minimizing operational costs due to granular activated carbon (GAC) reactivation and ion exchange media change-out.
• What Utilities Don't Know About GAC Reuse For PFAS For utilities building PFAS treatment systems, thermal reactivation of spent granular activated carbon (GAC) may sound like the obvious answer. However, service provider availability and location, specific media acceptance criteria including quantity thresholds, restrictions on GAC type and condition, and regulatory uncertainty can all determine whether reuse is a viable option.
• PFAS Funding Is Flowing — But Does The Water Sector Have Enough People To Deliver It? For several years, the PFAS conversation has centered on treatment options, testing, and funding. Those factors still matter, but they are no longer the primary constraint. Most utilities already understand the treatment routes available to them; the real challenge now is moving from technical possibility to operational performance, and that depends entirely on people.
• The Cost Of Waiting: Utilities Face A Narrowing PFAS Compliance Window For years, the water industry's PFAS conversation centered on monitoring, testing, and regulatory anticipation. Today, that phase is largely over.
• D.C. Circuit Upholds EPA's Hazardous Substance Designation For PFOA, PFOS

  The U.S. Court of Appeals for the D.C. Circuit recently rejected industry challenges to the EPA's designation of PFOA and PFOS as hazardous substances under CERCLA, leaving the agency's April 2024 rule fully intact. While the case centered on the EPA's authority to make the designation, its practical significance for water utilities is simpler: the liability concerns that have accompanied the rule since its adoption remain unresolved.
