  1. Double Belts, Double Suspenders: How El Paso Is Implementing Direct Potable Reuse 3/12/2025
    The city of El Paso, TX, has always known that water is precious. After its public utility, El Paso Water, previously piloted a direct potable reuse (DPR) plant to turn agricultural irrigation wastewater into drinking water, the city is now ready to begin construction of a full-scale, 10-MGD DPR facility.
  2. A New Way To Measure Phytoplankton And Cyanotoxin Producers In Large Rivers 3/12/2025

    Aquatic ecosystems, especially rivers, ponds, lakes, and reservoirs, can have variable levels of biological productivity that is directly proportional to their nutrient levels, or “trophic state”. Monitoring trophic state is critical to the protection of water resources. Among the many methods for monitoring, phytoplanktonic (microscopic algae) composition and abundance can comprehensively indicate the trophic status.
