Show DELAWARE RIVER BASIN COMPACT 175 further, That no single sample shall contain more than one hundred (100) organisms of the Coli Aerogenes group in one (1) milliliter. ';5. Such effluent shall be sufficiently free of acids, alkalis, and other toxic or deleterious substances, that it will not create a menace to the public health through the use of the water of the Delaware River for public water supplies, for recreation, industrial and other purposes, nor be inimical to fish, animal, or aquatic life. "6. Such effluent shall be free of offensive odors, and also be free of substances capable of producing offensive tastes and odors in pub- lic water supplies derived from the Delaware River at any place above or below the discharge of such effluent. "Zone 3. 1. Such effluent shall be free of noticeable floating solids, oil or grease, and substantially free of both settleaible solids and sleek. "2. Such effluent shall be stifficiently free of turbidity that it will not cause substantial turbidity in the water of the Delaware River after dispersion in the water of the river. "3. Such effluent shall show a reduction of at least fifty-five (55) per cent of the total suspended solids, and a reduction of not less than thirty-five (35) per cent of the bio-chemical demand. (It is the in- tent of this requirement to restore the dissolved oxygen content of the river water in this zone to at least fifty (50) per cent saturation. To accomplish this it may be necessary, in the case of certain wastes, to obtain reductions greater than those required under this item.) "4. Such effluent, if it be discharged within two miles of a public water wTorks intake, or within prejudicial influence thereof, shall at all times be effectively treated with a germicide. "5. Such effluent shall be sufficiently free of acids, alkalis, and other toxic or deleterious substances, that it will not create a menace to the public health through the use of the waters of the Delaware River for public water supplies, or render such waters unfit for industrial and other purposes, or cause the water of the Delaware River to be harm- ful to fish life. "6. Such effluent shall be practically free of substances capable of producing offensive tastes or odors in public water supplies derived from the Delaware River. "Zone 4. 1. Such effluent shall be free of noticeable floating solids, oil or grease, and substantially free of both settleable solids and sleek. "2. Such effluent shall be sufficiently free of turbidity that it will not cause substantial turbidity in the waters of the Delaware River after, dispersion in the water of the river. "3. Such effluent shall show a reduction of at least fifty-five (55) per cent of the total suspended solids and shall be subject to such further treatment as may be needed to prevent a nuisance. "4. Such effluent, if it be discharged within prejudicial influence of a public water works intake, or of recreational areas, or of shell fish grounds, shall at all times be effectively treated with a germicide except that in the case of recreational area influence, such treatment need not be provided during the period from October 15th to May 15th of each year. "5. Such effluent shall be sufficiently free of acids, alkalis, and other toxic or deleterious substances, that it will not create a menace to the public health through the use of the waters of the Delaware River |
