3.) unsuitable for recreational, commercial, industrial, agricultural, or for other reasonable uses; provided that:
a.) an alteration of the physical, chemical, or biological property of State waters, or a discharge or a deposit of sewage, industrial wastes or other wastes to State waters by any owner which by itself is not sufficient to cause pollution, but which, in combination with such alteration of, or discharge or deposit to State waters by other owners, is sufficient to cause pollution;
b.) the discharge of untreated sewage by any owner into State waters; and
c.) contributing to the contravention of standards of water quality duly established by the Board, are "pollution" for the terms and purposes of this chapter.
