The designation “lake” includes some marshes. 2 The state’s surface water classifications are as follows: Class I: Potable water supplies Class II: Shellfish propagation or harvesting Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife Class IV: Agricultural water supplies Class V: Navigation, utility, and industrial use (there are no state waters currently in this class) 3 The EPA’s 305(b)/303(d) Integrated Report categories are as follows: 1—Attains all designated uses; 2—Attains some designated uses; 3a—No data and information are available to determine if any designated use is attained; 3b—Some data and information are available, but they are insufficient for determining if any designated use is attained;
Water Quality Assessment Report: Middle St. Johns 101 Table 3.8 (continued) 3c—Meets Planning List criteria and is potentially impaired for one or more designated uses; 4a—Impaired for one or more designated uses and the TMDL is complete; 4b—Impaired for one or more designated uses but no TMDL is required because the impairment is not caused by a pollutant; 4c—Impaired for one or more designated uses, but no TMDL is required because an existing or proposed pollutant control mechanism provides reasonable assurance that the water will attain standards in the future; and 5—Water quality standards are not attained and a TMDL is required. 4 Parameters in bold meet the Verified List evaluation criteria, Section 62-303.400, F.A.C. 5 Parameters in italics are in Category 4 (a, b, or c) waters that do not require TMDL development. 6 The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple parameters. The hierarchy for assigning these categories is Category 5, then 4, then 3c, then 2, and then 3b, i.e., each WBID is assigned a category based on the highest category assigned to an individual parameter. For example, if WBID 9999 has total coliforms as Category 5, fecal coliforms as Category 3c, and coliforms-shellfish as Category 2, the single assessment call for the WBID is Category 5. F = Fresh water M = Marine DO = Dissolved oxygen TSI = Trophic State Index the Ocklawaha Basin. The facility discharging the smallest amount is the Pierson Laundromat (0.0043 mgd), an industrial wastewater source discharging into the Price Creek watershed. Another notable facility is River Park Utilities, discharging 0.025 mgd. This facility has its own reuse system. Appendix G lists, by planning unit, the permitted dischargers in the basin. Other contributors of point source discharges include one closed Class I and two closed Class II solid waste landfills, as well as one closed construction and debris landfill. There are no delineated areas under Chapter 62-524, F.A.C., Potable Delineated Water Well Permitting in Delineated Areas, and no Superfund or state-funded hazardous waste sites. Nonpoint Sources. Water (32.7 percent), upland forest (30.8 percent), and wetlands (21.6 percent) occupy most of the land area in the planning unit. Urban and built-up lands cover about 7 percent of the total land area, mostly concentrated around the town of Pierson, on the eastern side of the planning unit, or on the north shore of Lake George. Agriculture accounts for 5.4 percent of the total land area. These developed land uses can be associated with nonpoint discharges of pollutants and eroded sediments. Appendix H provides a detailed analysis of land use in the basin, by planning unit. Major pollution in the planning unit comes from urban and agricultural runoff. Specifically, the SJRWMD estimated that 2.3 million pounds of pesticides were used in 1988, with an unknown amount entering the St. Johns River just upstream of Lake George. It also has been suggested that leakage of old sanitary sewers could be contributing to water quality degradation. The St. Johns River, however, is probably responsible for the highest pollution loading into the basin (Alvarez, Lehman, and Associates, 1991). Ecological Summary The Lake George State Forest is one of several publicly owned tracts of land encircling Lake George. The St. Johns River borders three and a half miles of the forest and provides a wealth of ecologically valuable
