Launched by WateReuse and supported by four water industry associations, the comprehensive guide for water reuse practitioners and regulators aims to address scientific, legal and policy considerations, in addition to providing strategies for collaboration during the regulatory development process. It is expected to be the first nationwide water reuse guide of its kind, equipping reuse practitioners to help develop or update regulations that fit their state’s situation versus providing specific regulatory recommendations. Brown and Caldwell will collaborate with Hazen & Sawyer (New York, N.Y.) on the project, drawing upon both companies’ experience in water reuse projects.

EPA announces $3B for states to reduce lead in drinking water

The U.S. Environmental Protection Agency (EPA) announced $3 billion in new funding for states through State Revolving Fund (SRF) programs to reduce exposure to lead in drinking water. EPA conducted a review of previously awarded funding and assessed updated lead service line data to increase accountability and ensure funds are properly distributed. The agency released new information indicating fewer lead service lines nationwide than previously estimated. EPA’s updated estimate is 4 million lead service lines, down from 9 million. This significant reduction is driven by improved data provided by service line inventories required under Lead and Copper Rule Revisions. The agency is also releasing a new dashboard highlighting information from lead service line inventories provided by states.

Study finds positive climate effects from targeted lake remediation

BlueGreen Water Technologies (Houston), a company with a mission to restore the health and safety of water bodies worldwide, announced a peer-reviewed study in Phycology demonstrating that targeted lake remediation of harmful algal blooms (HABs) can significantly mitigate greenhouse gas emissions and create climate resilience for water scarce areas. According to BlueGreen, the study scientifically validates the company’s interventions, demonstrating how strategic HAB management can reduce methane and nitrous oxide emissions. The study found substantial methane reductions following targeted lake treatments, while post-treatment around 45% of HAB-derived biomass is retained in lake bottom sediments for millennia, serving as a durable carbon sink. BlueGreen’s Lake Guard technology remediates HABs and is supported by BGi, the firm’s remote digital monitoring platform.

Kisters announces technology to improve environmental sensors

Kisters (Aachen, Germany) has unveiled a new embedded technology that transforms conventional environmental sensors into fully integrated, connected devices. According to Kisters, KIPTEC removes the need for separate loggers and modems, speeds up field installation, and can cut power use by up to 75%. KIPTEC builds all processing, dynamic logging, telemetry, and power management directly into the sensor, creating a single unit. “The market demanded simplicity,” said Anton Felder, director of Kisters HydroMet. “With 93 percent of monitoring professionals reporting issues tied to multi-device installations, complexity itself had become the barrier. KIPTEC removes that barrier by building connectivity, logging and processing directly into the sensor.”
