Spectroscopy Rides a Rising Tide of Water-Monitoring Applications
In 2018, when California became the first state to pass legislation requiring the measuring of microplastics in drinking water supplies, it essentially set off a competition that would pit photonic technologies against one another as well as nonphotonic counterparts. To determine which technologies could most precisely, consistently, and cost-effectively measure microplastics, California’s State Water Resources Control Board, or State Water Board, recruited 22 laboratories to evaluate...
