HAR §11-54-8. Recreational criteria for all state waters

(a) These criteria are designed to protect the public from exposure to harmful levels of pathogens while participating in water-contact activities. The specific criteria for enterococci shall be expressed in colony forming units (CFU) per one hundred milliliters or as a most probable number (MPN) per one hundred milliliters, as specified by the analytical method used. 54-66 3435 §11-54-9.1.01 (b) Enterococci content shall not exceed a geometric mean of thirty-five CFU per one hundred milliliters over any thirty-day interval. (c) A Statistical Threshold Value (STV) of one hundred thirty CFU per one hundred milliliters shall be used for enterococci. The STV shall not be exceeded by more than ten per cent of samples taken within the same thirty-day interval in which the geometric mean is calculated. (d) State waters in which enterococci content does not exceed the standard shall not be lowered in quality. (e) Raw or inadequately treated sewage, sewage for which the degree of treatment is unknown, or other pollutants of public health significance, as determined by the director, shall not be present in natural public swimming, bathing, or wading areas. Warning signs shall be posted at locations where human sewage has been identified as temporarily contributing to the enterococci count.
