Clark County Water Reclamation District (CCWRD) has partnered with the Southern Nevada Water Authority (SNWA) to investigate the feasibility of using ozone to disinfect its filtered secondary effluent and oxidize organic contaminants, to serve the drinking water needs of the Las Vegas valley. CCWD is aimed to remove estrogenic chemicals from its wastewater discharges by the use of ozone technology as it is effective for the oxidation of many microcontaminants. Estrogenicity is determined by comparing the number of cells in cultures exposed to the extract to that of control cells, while is measured in terms of estrogen equivalent units. The study results show that the total organic carbon (TOC) levels in CCWRD's secondary effluent ranged from 5.4 mg/L with the lower concentrations occurring in summer and the higher concentrations occurring in winter.
