The objective of this study was to test the ability of non imprinted polymers (NIPs) for treatment of a variety of endocrine disrupting compounds (EDCs) for water and wastewater treatment, or water reuse. NIPs were tested with water spiked with a variety of EDCs. NIP were capable of removing greater than 99% of 17-β estradiol (E2), 99.7% of 17-α bisphenol A (BPA), 74.6 % of atrazine, and 44.8% of diethylstilbestrol. NIP particles were also tested for their ability to remove both remaining EDC concentrations as well as any daughter products formed for use as a polishing step following chlorination. Results showed that for chlorination of a 10 ppm E2 solution with 5 mg/L of chlorine and a 15 minute contact time, 5 mg/mL of NIP particles were capable of completely removing any residual E2 as well as daughter products which were formed.
