There is a major problem with hydroxyl radical oxidation processes suggested below. They are extremely inefficient. The OH radicals are indiscriminate so they react with all of the TOC. Suppose you have 20 mg/L (20,000 ug/L) of TOC and 2 ug/L of endocrine chemical. The TOC is 10,000 times the endocrine to be removed. It consumes a lot of wasted energy and cost. Advanced oxidation processes are usually applied to relatively clean water e.g. after RO treatment, so that there is not as much extraneous TOC to compete.
