Texas waterways microplastic contamination

A July 26 study by the Environment Texas Research and Policy Center sampled 77 North Texas water bodies—including the Trinity River, White Rock Lake, Mountain Creek Lake and Lake Lewisville—and found microplastics at virtually every site, with 99% of locations containing at least one type of plastic residue. Microfibers were the most common pollutant, and plastic pellets also appeared, raising concerns about wildlife harm, food‑chain impacts and human health, as well as potential economic damage to fishing and tourism.

A follow‑up analysis published on July 31 expanded the scope to a statewide level, covering rivers, lakes, reservoirs and other water bodies from Brownsville to the Red River and the Gulf of Mexico. The survey detected microplastics in 76 of the 77 waterways, confirming the earlier findings. Fibers were present in 96% of samples, followed by fragments, film and industrial nurdles. Researchers reiterated the invisible nature of the contamination and called for policy measures, including phasing out single‑use plastics, limiting petrochemical expansion and tightening controls on plastic pellet emissions, noting Texas hosts 36 facilities that produce such pellets.
