703.4 Water quality standards for coliforms, enterococci, and E. coli.
Total and fecal coliform, enterococci, and E. coli standards for specific classes are provided in this section.
(a) Total coliforms (number per 100 ml).
ClassesStandard
AAThe monthly median value and more than 20 percent of the samples, from a minimum of five examinations, shall not exceed 50 and 240, respectively.
A, B, C, D, SB, SC, I, SDThe monthly median value and more than 20 percent of the samples, from a minimum of five examinations, shall not exceed 2,400 and 5,000, respectively.
SAThe median most probable number (MPN) value in any series of representative samples shall not be in excess of 70.
A-SpecialThe geometric mean, of not less than five samples, taken over not more than a 30-day period shall not exceed 1,000.
GAThe maximum allowable limit is 50.
(b) Fecal coliforms (number per 100 ml).
A, B, C, D, SB, SC, I, SDThe monthly geometric mean, from a minimum of five examinations, shall not exceed 200.
A-SpecialThe geometric mean, of not less than five samples, taken over not more than a 30-day period shall not exceed 200.
(c) The total and fecal coliform standards for classes B, C, D, SB, SC and I shall be met during all periods:
(1) when disinfection is required for SPDES permitted discharges directly into, or affecting the best usage of, the water; or
(2) when the department determines it necessary to protect human health.
(d) Enterococci (number per 100 mL [colony-forming units or most probable number]).
ClassesStandard
Coastal recreation waters of the following classes: SA and SBThe geometric mean of samples collected over any consecutive 30-day period shall not exceed 35, and no more than 10 percent of the samples collected in the same 30-day period shall exceed 130.
(e) E. coli (number per 100 mL [colony-forming units or most probable number]).
ClassesStandard
Coastal recreation waters of the following classes: A, A-Special, AA, AA-Special, and BThe geometric mean of samples collected over any consecutive 30-day period shall not exceed 126, and no more than 10 percent of the samples collected in the same 30-day period shall exceed 410.
(f)
(1) The enterococci standards for Class SA and SB coastal recreation waters shall apply:
(i) during the period of May 1st through October 31st;
(ii) in any other instance where the department determines it necessary to protect human health or the best usages of the waters; and
(iii) where required by State or Federal law or interstate compact.
(2) The E. coli standards for Class A, A-Special, AA, AA-Special and B coastal recreation waters shall apply:
(i) during the period of May 1st through October 31st;
(ii) in any other instance where the department determines it necessary to protect human health or the best usages of the waters; and
(iii) where required by State or Federal law or interstate compact.
(g) Site-specific enterococci.
Standards in the table below will be assessed as a geometric mean of samples collected over a 30-day period during the recreational season of May 1st through October 31st. The recreational season may be expanded in any instance where the department determines it necessary to protect human health or the best usages of the waters, or where required by State or Federal law or interstate compact. Units for the standard are number per 100 mL (colony-forming units or most probable number).
