	abstract = {<p>Changes in the microbial quality of nonpotable reclaimed water distribution systems in seven metropolitan areas of the southwestern United States were investigated by performing pathogen monitoring and bacterial growth. Water samples were collected from tertiary-treated effluents at point of entry and point of use in the distribution systems. The samples were analyzed for Cryptosporidium oocysts, Giardia cysts, enteroviruses, microbial indicators, and assimilable organic carbon (AOC). Cryptosporidium and Giardia were detected in 16{\%} (12/77) and 43{\%} (33/77) of nonpotable reclaimed water samples, whereas no infectious Cryptosporidium parvum were detected in any of the samples. No infectious enteroviruses were detected in any sample (0/27). At point of entry total coliform and fecal coliforms ranged from 0.7 to 280 and from 0 to 1.9 colony-forming units (cfu)/100 mL, respectively. Increases in the number of coliforms were observed as water passed through the reclaimed water distribution systems. However, no ...</p>
