(a) General knowledge of the medical profession and related scientific fields as to materials and substances which are harmful to humans if ingested through drinking water; and

(b) General knowledge of the medical profession and related scientific fields as to the maximum amounts of such harmful materials which may be ingested by human beings, over varying lengths of time, without resultant adverse effects on health.

This priority system shall be reviewed annually by the director.
