The quality, treatment and monitoring of water for laboratory rodents.

A water quality standard for laboratory rodents has not been established nor given serious consideration. Yet many studies have shown on occasion the presence of heavy metals, polycyclic hydrocarbons (some known to be carcinogens) as well as microscopic organisms. All of these materials may have significant impacts upon the outcome of an experiment if proper attention is not given to their presence and control. Several methods and systems for the control of these extraneous factors are discussed.
