§ 27-195. Water quality standards.

Latest version.

(a)

Standards for marine waters: Water quality standards appearing in Table 1, Marine, are applicable to all marine surface waters (salt). Where applicable, compounds are identified by a Chemical Abstract Service Number (CAS#). If differences exist between the following standards and the criteria specified in the Rule 62-302.530, F.A.C., Class III Surface Water Quality Classifications; Predominately Marine Waters, which are incorporated by reference, the most stringent standard shall apply.

(b)

Standards for fresh waters: Water quality standards appearing in Table 1, Fresh, are applicable to all fresh surface waters. Where applicable, compounds are identified by a Chemical Abstract Service Number (CAS#). If differences exist between the following standards and the criteria specified in the Rule 62-302.530, F.A.C., Class III Surface Water Quality Classifications; Predominately Fresh Waters, which are incorporated by reference, the most stringent standard shall apply.

(c)

Standards for ground waters: Water quality standards appearing in Table 1, Ground, are applicable to all ground water. Where applicable, compounds are identified by a Chemical Abstract Service Number (CAS#). If differences exist between the following standards and the criteria specified in Rule 62-520.420, F.A.C., Standards for Class G-I and Class-II Ground Water, which are incorporated by reference, the most stringent standard shall apply.

TABLE 1
BROWARD COUNTY WATER QUALITY STANDARDS
FOR MARINE, FRESH (SURFACE) AND GROUND WATERS

Unless otherwise stated, all criteria express the maximum not to be exceeded at any time. In some cases there are separate or additional limits, such as annual average criteria, which apply independently of the maximum not to be exceeded at any time. N.S. appears for compounds where no standard has been set.

(d)

Other compounds: If toxic or undesirable compounds other than those listed in Subsection (a), (b), or (c) of this Section, or referred to in Rules 62-302.530 and 62-520.420, F.A.C., as amended, are present, EPGMD, based on the latest scientific knowledge concerning toxicity and adverse effects on the intended water use, may specify limits.

(e)

Synergistic action: Whenever evidence indicates that a combination of pollutants exerts a greater effect than the individual pollutants, the EPGMD may, on the basis of these findings, lower the limits established in Subsections (a), (b), or (c) of this Section.

(f)

Sampling locations:

(1)

Sampling for water quality analysis in marine water shall be at those points where no further treatment is given to the waste stream or stormwater, yet prior to discharge to the receiving body of water, such as at a discharge structure or outfall.

(2)

Sampling for water quality analysis in fresh water shall be at those points where no further treatment is given to the waste stream or stormwater, yet prior to discharge to the receiving surface water, such as at a discharge structure or outfall.

(3)

In sampling for contamination from a point source to ground water, the samples shall be taken from wells at such depths and locations to provide data to facilitate determining the magnitude, extent and consequences of such contamination as approved by EPGMD. In the case where there is a discharge to ground water (either accidentally or intentionally), the discharger (if known), or the owner of the property (if the discharger is unknown), shall be required to install the wells and provide sampling and analysis by a State of Florida certified laboratory in accordance with the latest version of the EPGMD Minimum Criteria for Monitoring Wells and Sampling and provide results to the county. In addition, the wells shall be made available to the county for its own sampling activities. Test wells shall be required by EPGMD to be installed by the discharger or owner of the property that discharges into the ground water and maintained at the discretion of EPGMD if existing sampling points are found to be inadequate in the judgment of EPGMD. If a discharge of hazardous materials occurs, either accidentally or intentionally, the owner or discharger should follow Article XII of Chapter 27.
