Mikvah (or mikveh) is a specific type of bath designed for the purpose of
ritual immersion in Judaism. The word "mikvah", as used in the Hebrew Bible,
literally means a "collection" - generally, a collection of water.[1]
Several biblical regulations specify that full immersion in water is required
to regain ritual purity after ritually impure incidents have occurred. Most
forms of impurity can be nullified through immersion in any natural
collection of water. Some, such as a Zav, however require "living water,"[2]
such as springs or groundwater wells. Living water has the further advantage
of being able to purify even while flowing as opposed to rainwater which must
be stationary in order to purify. The mikvah is designed to simplify this
requirement, by providing a bathing facility that remains in ritual contact
with a natural source of water.
