Twelve different waters from filtered water utilities across the United States were collected and
evaluated for UV disinfection of MS2 coliphage under a single bench scale inactivation and
microbial analysis protocol. The average and 95 percent confidence interval for log survival as a
function of UV dose for the MS2 coliphage tested in these filtered water utilities was found to lie
within the guidelines proposed by the NWRI for bench scale UV disinfection studies. The
inactivation of MS2 was not affected by turbidity, particle count, or UV absorbance within the
bounds of these waters in compliance with regulations for filtered water utilities. From these
results, it appears that treated water from filtered utilities in compliance with federal standards
for water quality are readily amenable to UV treatment for disinfection. In addition, the
validation of UV disinfection systems as it relates to water quality may not need to be site
specific aside from accounting for water quality parameters that directly affect the UV
disinfection process such as UV absorbance. Includes 9 references, table, figures.
