Many industrial wastes are highly acid or alkaline, and either condition can interfere with aquatic life, domestic use, and other uses. An accepted measurement of a waste's acidity or alkalinity is its pH.9 Before wastes are dis- charged they should have a pH~s~imilar to that of the receiving water.
