In July 2011, Greenpeace released its Dirty Laundry report accusing some of the world's top fashion and sportswear brands of releasing toxic waste into China's rivers. The report profiles the problem of water pollution resulting from the release of toxic chemicals associated with the country's textile industry. Investigations focused on wastewater discharges from two facilities in China; one belonging to the Youngor Group located on the Yangtze River Delta and the other to Well Dyeing Factory Ltd. located on a tributary of the Pearl River Delta. Scientific analysis of samples from both facilities revealed the presence of hazardous and persistent hormone disruptor chemicals, including alkylphenols, perfluorinated compounds and perfluorooctane sulfonate.
