In many areas of the world, utilities have pursued projects that utilize current water resources to
plan for future droughts, to protect water resources, to recharge wellfields and/or to store water
for use at a later time. A benefit could be realized if the water could be stored for later use rather
than discharged to rivers, reservoirs, oceans or other sources. The use of alternative groundwater
injection programs has been proposed to address the need for conserving scarce water resources.
However, injecting waters of less than pristine (or impaired) quality has met with limited success
or significant resistance. The resistance is caused by the risk of effects to the public should these
waters be recovered in water supply wells at a later point in time. For groundwater injection
projects, the regulatory agencies appear to believe that viral agents pose the greatest risk, since
viruses are thought to move farther and faster than other biological constituents, and to retain
their viability for lengthy periods of time. Risk is defined as the probability of causing a
response (infection) in an individual who later consumes the injected water. Unfortunately, there
is virtually no data on viral impacts, so any risk analysis will need to incorporate methods that
can deal with limited data. The use of predictive Bayesian methods meets this criterion. Includes 8 references, table, figures.
