Two very high values were removed 

from the assessment, as it was 

confirmed by the FDEP NE District 

that these were caused by turbid 

water entering Long Branch due to a 

dike break resulting from mining 

activities at a nearby facility. A 

natural background turbidity of 16.8 

NTU was assumed based upon the 

lower 20th percentile of 28 turbidity 

measurements taken during the 

planning and verified periods. The 

threshold of impairment becomes 

45.8 NTU, which was used to 

determine the number of 

exceeedances in the planning and

 Florida's waterbody classifications are defined as: 

 1 - Potable water supplies 

 2 - Shellfish propagation or harvesting

 3F - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in fresh water

 3M - Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in marine water

 4 - Agricultural water supplies

 5 - Navigation, utility, and industrial use

2

 n is equal to the number of samples. When samples are collected at the same location less than 4 days apart, the median of those results represents a single sample for the purpose of determining n. 

3 The Cycle 1 assessment was done in 2003 and included data from that Verified Period (January 1, 1996 through June 30, 2003).

4 The Cycle 2 assessment is the current assessment and includes data from the Verified Period (January 1, 2001 through June 30, 2008).

 † EPA's Integrated Report Category:

 1 - Attains all designated uses

 2 - Attains some designated uses and insufficient or no information or data are present to determine if remaining uses are attained

 3A - No data and information are present to determine if any designated use is attained

 3B - Some data and informationare present but not enough to determine if any designated use is attained

 3C - Enough data and information are present to determine that one or more designated uses may not be attained according to the Planning List methodology

 4A - Impaired for one or more designated uses but does not require TMDL development because a TMDL has already been completed.

 4B - Impaired for one or more designated uses but does not require TMDL development because the water will attain water quality standards due to existing or porposed measures.

 4C - Impaired for one or more criteria or designated uses but does not require TMDL development because impairment is not caused by a pollutant.

 4D - The waterbody does not meet applicable criteria, but no pollutant can be identified; therefore a TMDL will not be developed at this time.

 4E - Impaired, but recently completed or on-going restoration activites are underway to restore the designated uses of the waterbody.

 5 - Water quality standards are not attained and a TMDL is required.

 Where a parameter was identified as impaired, a priority of “medium” was assigned. Exceptions are waters where the impairment poses a threat to potable water or 

 human health, which have been assigned a “high” priority, and fecal coliform impairments, which have been assigned a “low” priority. All other listings as of this cycle are prioritized based

 on the following: it is our intent that listings with a "High" priority be addressed within the next 5 years, listings with a "Medium" priority be addressed within 5-10 years as resources allow,

 and listings with a "Low" priority be addressed within the next 10 years.

 VP - Verified Period (January 1, 2001 through June 30, 2008)

* A statewide TMDL for mercury, that will address this waterbody, is scheduled to be completed in 2012.

^ Beach advisories are based on FL Dept of Health Enterococcus (>103 CFU/100mL) or fecal coliform (>399 CFU/100mL) criteria.

N/A = Not Applicable

Beach advisory data is based on "DOH_beach_stations" file created 10/06/2008 by Barbara Donner of FDEP.

Fish advisory data is based on "2008_fish_advisories_by_WBID" file created 12/12/2008 by Barbara Donner of FDEP.

The Group 2 Lower St. Johns Master list is based on IWR Run 35_2.
