This paper examines a large dataset of dose response curves
generated during ultraviolet (UV) reactor validations undertaken according to the U.S. Environmental Protection Agency's (USEPA) Ultraviolet
Disinfection Guidance Manual 1 (UVDGM), and discusses the range and implications of
their variability and accuracy.
The surrogate most commonly used in the U.S. and Canada for UV validation is the
coliphage MS2. Guidance on acceptable ranges of that organism's UV dose response has
been issued, in the UVDGM, and in the NWRI/AwwaRF 2 guidelines. However, each of
these guidelines was prepared from limited historical databases; their validity in light of the
recent impetus to precisely measure UV irradiance during dose response characterization
has not been fully evaluated. This presentation examines a large database of MS2 dose
response curves generated during UV reactor validations involving this research team and
assesses these against the above guidelines, and vise versa. Also, these datasets are
compared using the UVDGM's criteria for assessing differences between dose response
curves, and variability of inactivation kinetics within and across a range of doses are
evaluated. Includes 5 references, figures.
