Wastewater Monitoring: A Shift from BOD/COD to Total Organic Carbon Analysis

 Alongside rising global population levels is the continual development and expansion of various industries, including pharmaceuticals, refining and manufacturing.  In spite of their differences, each of these industries is responsible for a generation of extremely contaminated waters and has a vested interest in ensuring water quality. Image credit: Avatar 023/Shutterstock.com Both municipal and industrial wastewaters present considerable health risks to human health and also endanger the environment; thus, all wastewaters must be carefully treated and closely monitored before being discharged. As the public continues to push for human health and environmental protection, wastewater discharge regulations are becoming more strict. Each country possesses its own wastewater governing body and various discharge limits, resulting in the development and use of a diverse range of monitoring methods.

Federal Hydrogen Regulation In The United States: Where We Are And Where We Might Be Going | Vinson & Elkins LLP

Overview Hydrogen has over the last century enjoyed repeated bouts of interest as a fuel source. Though these have repeatedly fallen flat, hydrogen-based production has recently enjoyed a renaissance, due to a trifecta of improving political, economic, and technological conditions. Importantly, hydrogen presents an answer to a major problem in the energy transition debate: decarbonizing fuel sources while maintaining energy security and reliability. While electrification has a first-mover advantage in certain areas (e.g., light-duty vehicles), hydrogen is seen as particularly viable in “hard-to-decarbonize” sectors such as heavy-duty transportation, which requires fuel supply for substantial distance and payloads. These trends are still nascent. There has long been a small hydrogen market, primarily for industrial applications;
