What is the definition of "acute" and "chronic" as it pertains to drinking water?
Acute is defined as "occurring over a short period of time; used to describe brief exposures and effects which appear promptly after exposure." Chronic is defined as "occurring over a long period of time, either continuously or intermittently; used to describe ongoing exposures and effects that develop only after a long exposure (Drinking Water Glossary: A Dictionary of Technical and Legal Terms Related to Drinking Water; EPA810-B-94-006, June 1994)."
