Microplastic shards plague every Colorado river. Here’s where, and how they get there
Lexi Kilbane knew, in a vague, nonscientific way, that plastic pollution was a growing problem, and that tiny shards of plastics were showing up everywhere a microscope might look. But the magnitude of the contamination finally hit home after she dipped a water testing kit into a City Park lake, right near her house, and filtered the sample. Fibers from shredded tarps, jackets and carpet popped into view, in a dystopian kaleidoscope. … Using national protocols for detecting microplastics, Kilbane and the nonprofit advocacy group CoPIRG sampled 16 waterways in Colorado and found the plastics pollution in every one. They are sharing results of their study with national sampling networks, and urging Colorado policymakers to double down on recent efforts to slow use of plastics that deteriorate into dangerous particles but never biodegrade.
