2.2 WATER QUALITY CONCERNS
2.2.1 Water Quality Project
The Alachua County Environmental Protection Department (ACEPD) provided input as to numerous special project needs related to water quality assessment and/or improvement in the County. The projects identified are summarized in Table 2-1 below:
Table 2-1 Water Quality Projects
Project Name Project Description General Location
Stormwater Inflow/Outfall
Inventory
In order to adequately assess which basins contribute to poor surface water quality and direct untreated stormwater into the Floridan aquifer an inventory of basins must be performed. Inflow and outflow nutrient concentrations are important for wet basins under both baseflow and stormwater flow conditions. Inflow is most important for dry basins as most do not have a surficial discharge but infiltrate into the ground. EPD staff will conduct an inventory of stormwater ponds and outfalls, including receiving waters; mapping contributing areas and land uses and prioritize for future monitoring.
Alachua County
Stormwater Management in
Karst Areas
Stormwater treatment in karst areas can negatively impact groundwater quality. Improved designs and sinkhole management can improve water quality and protect the Floridan aquifer. In some areas of western Alachua County, groundwater currently exceeds the state drinking water standard of 10 mg/L for nitrate. Increased runoff into sinkholes and other solution features can further increase nitrate concentrations. Solutions include redirecting stormwater from directly discharging to sinkholes and incorporating pretreatment. EPD staff will conduct and inventory of stormwater ponds discharging directly to sinkholes; map and prioritize for future mitigation.
Western Alachua
Co.
Stormwater Quality
Assessment of Stream to Sink
Basins
The objective is to conduct water quality monitoring in order to evaluate water quality impacts of stream to sink basins. In 21 streams untreated stormwater directly discharges to swallets or sinkholes which recharge the Floridan aquifer. Two of these stream to sink systems, Mill Creek and Lee Sink, have direct connections to Hornsby Spring as verified by qualitative dye tracing in July 2005. All of these stream to sink systems represent a considerable amount of recharge to the Floridan aquifer which is the primary source of drinking water to Alachua County. Protecting the quality of this aquifer from untreated stormwater is essential.
Central Alachua
Co.
Stormwater Inflow/Outfall
Sampling - Baseflow and
Stormwater Flow Monitoring
The objective is to conduct water quality monitoring to evaluate effectiveness of LID retrofit projects in improving water quality. Inflow and outflow nutrient concentrations are important for wet basins under both baseflow and stormwater flow conditions. Inflow is most important for dry basins as most do not have a surficial discharge but infiltrate into the ground. Installation of monitoring wells to obtain information of groundwater nutrient concentrations would be necessary in evaluating the effectiveness of basins for protecting groundwater quality.

Project Name Project Description General Location
Groundwater Nutrient
Assessment in the Santa Fe Basin
The objective is to evaluate nutrient (nitrogen and phosphorus) data to assess landuse and stormwater impacts to the groundwater in western Alachua County and the springsheds of Poe and Hornsby. The Santa Fe River, an Outstanding Florida Water (OFW) is listed by the state as an impaired waterbody for nutrients. Spray fields for WWTP effluent disposal in High Springs, Alachua and Newberry are negatively impacting groundwater nitrate concentrations. Poor stormwater management will cause further degradation of groundwater that discharges to the Santa Fe River and associated springs. EPD staff will secure and manage a contract with a consulting firm for developing nutrient loading / mass balance from existing data
Western Alachua
Co.
Lake Santa Fe and Lake Alto Water
Quality Monitoring
The objective is to assess landuse and stormwater impacts to the water quality at Lake Santa Fe and Lake Alto. Lake Santa Fe is an OFW. Lake conditions currently place it in the mesotrophic category. It is important to reduce stormwater impacts to the lake and help reduce the potential for further eutrophication. EPD staff will conduct quarterly monitoring at six stations in Lake Santa Fe and two in Lake Alto
Lake Santa Fe
Stormwater Pond Vegetative
Enhancement for Water Quality Improvement
The objective is to improve existing stormwater systems via vegetative enhancements. Two wet ponds or semi-wet ponds will be selected annually for vegetative enhancement. Plantings will include establishing a canopy with larger trees around the upper portions of the basins and installing trees and herbaceous materials along the shoreline itself.
Alachua County
Stormwater Basin Fertilizer Use Pilot
Project
The objective is to conduct a pilot study to assess the impact outreach and education efforts on fertilizer use in residential areas. Evaluate outreach efforts to determine the best course of action to reduce fertilizer use and make the use of fertilizers more effective. Pilot project for three areas draining to stormwater ponds; 3 treatments (1 - full outreach and personal visits, 2- BMP mailers, 3- control); Wet and dry season sampling.
Western Alachua
Co.
Water Quality Protection BMP Training and Water Quality
Protection Public Education and
Outreach
Training and education for homeowners, commercial and industrial interests in sedimentation and erosion control and nutrient management to improve stormwater quality. The Santa Fe River is impaired for nutrients, as is Newnans Lake. Lochloosa and Orange lakes have deteriorating water quality and increased suspended solids and nutrients. The springs along the Santa Fe River are showing increasing degradation. Public education to promote stormwater nutrient (nitrogen and phosphorus) reduction is essential to protect groundwater and surface water resources. This is important in eastern Alachua County due to proximity of lakes and streams and in the central and western Alachua County due to the unconfined nature of the Floridan aquifer and the occurrence of stream-to-sink basins.

Stormwater Management
Ponds
This project proposes water quality retrofits for water quality improvement in various drainage retention/detention areas or ponds throughout the County. Many of these ponds were created primarily for the purpose of water storage and flood protection, before design requirements for water quality improvement were implemented. As part of the retrofit projects, further evaluation of the drainage retention/detention areas will be conducted including the following: (1) identifying failed drainage areas that do not function as designed and permitted, (2) determining if these areas meet current water management district and Alachua County design criteria, and (3) evaluating remedial options and water quality improvement of the proposed retrofits. Drainage retention/detention area function will be evaluated using available plans, as-builts and through discussions with regulatory agencies. Selected areas or ponds will then be assessed using geotechnical investigations to analyze existing soil conditions and stratigraphy and determine the cause(s) for drainage area failure. Where possible, forebays, for sediment removal, and permanent pools (in wet detention systems) will be incorporated into the retrofit designs. Wet detention systems will be evaluated for existing infrastructure (inflow and outfall structures and piping) and littoral zone planting. Efforts on wet detention systems will focus on enhancement of pond function, improved water quality and native vegetative community structure and plant diversity. Projects involving dry retention areas will focus on pond function, native vegetative enhancement, and removal of invasive exotics. Retention/detention areas failing to meet permitted design requirements will be prioritized for water quality improvement. A listing of the identified projects is included on Table 2-2 with locations shown on Figure 2-4. LID principles should be considered in all proposed stormwater upgrades and new constructions in the County. Stormwater treatment technologies have vastly improved in recent years. Using LID techniques and basin redesign to improve water quality is essential. Redesigning wet basins to incorporate features such as a forebay for sediment control and berms to allow longer residence times will improve water quality, whether it is discharged to surface water or groundwater. Using techniques for partially "dry basins" that include infiltrating wetlands may mitigate potential impacts to groundwater and surface water quality. The potential for use (as a retrofit) of denitrification walls to reduce nitrates may exist in certain scenarios. Stormwater treatment using wetland treatment system such as infiltrating wetlands can improve potential impacts to groundwater and surface water quality. Improved designs that include denitrification can lower nitrogen inputs to waterbodies and ground water. Disturbed wetlands have often lost primary functions such as water quality enhancement. Restoration or "retrofit" of these disturbed wetlands will provide enhanced water quality in the entire watershed.
Alachua County
Roadside Drainage
Improvement
This project proposes water quality retrofits for roadside drainage improvement at various locations throughout the County. The road conditions at these location result in high sediment loadings to nearby surface water bodies. Potential improvements include grade control with swale ditch blocks, stabilizing soils, and re-vegetation. A listing of the identified projects is included on Table 2-3 with locations shown on Figure 2-5.

An example of one of the roadside improvement projects (#9) is the area of NE 179nd Street in Orange Heights (north of SR26 just east of US 301). This area has been a concern of the County’s as well as the SJRWMD. The graded road (NE 179nd Street) is wide and during rainfall events water flows south on the west side of NE 172nd Street and into the FDOT concrete lined swale on the north side of SR26. This in turn flows under SR 26 to wetlands that are the headwaters for Lochloosa Creek. The first below photograph shows turbid water from a recent rainfall event at a portion the eroded area along the west side NE 172nd Street and the FDOT swale. The second below photograph shows the FDOT lined channel. The swale area along the west side of NE 172nd Street needs to be stabilized and water directed to a vegetated swale to eliminate/reduce the turbid water discharge during rainfall events.

Another example of a roadside improvement project (#11) is where Lochloosa Slough is crossed by SE 225th Drive. At this location there is considerable trash along the road and in the slough itself. The below photograph shows waste in the water adjacent to the road near the culvert that should be removed to protect water quality. Trash, as well as sediment discharge to the wetlands, are on-going problems along this road.
For project roadside improvement project #5 at Little Orange Creek at 219A and CR 1474, remnants of recent erosion along the culvert headwalls and in the swales was observed on 219A and CR 1474 west of CR 219A. Stabilization of soils in these areas is important. A resident in the area also reported possibly related bridge problems on his property east (downstream) of CR 219A. The resident said logs and debris needed to be cleared from what he understood was a county maintained drainage easement along the creek upstream and adjacent to the property. Debris appeared to be threatening the stability of his bridge over the creek. The bridge structure itself may also require improvements.
These projects represent actions intended to increase the County’s responsiveness to the water quality needs of its citizens through the gathering and compilation of valuable information and implementation of responsive programs and guidelines. In order to implement the above projects, additional staff resources for administration are necessary. Additional equipment and funding resources would also be necessary in some instances.
Implementation of these projects to further the County’s focus on improving water quality in its lakes, streams, and aquifer represents a need that Alachua County should address. To address this need, additional staff and project funding resources would be required beyond what the County currently has allocated.

2.2.2 Basin Management Action Plans
Current Total Maximum Daily Loads (TMDL) regulations have resulted in the need to develop Basin Management Action Plans (BMAPs). BMAPs are developed by a multidisciplinary taskforce of stakeholders with interest in the particular TMDL water body or water bodies affected. The task force works together to develop a binding plan of action which works towards the TMDL goals. Typical BMAP components include:
1. Compile existing data and identify data gaps
2. Identify pollutant sources & estimates of associated loading
o Quantify sources (point and non-point), including growth
3. Share responsibilities for load reductions
o Produce detailed allocations
4. Develop management actions
o Describe existing and proposed management actions, and estimate expected pollutant reductions
5. Develop implementation schedule and funding
6. Establish mechanisms to show progress
o ambient monitoring, evaluation, and reporting
o implementation monitoring
o adaptive management measures
The primary BMAPs the County will need to address in the future are for Orange Creek and the Santa Fe River TMDL planning units. These areas are shown on Figure 2-6.
The Orange Creek BMAP process culminated in the plan being adopted in May 2008. The BMAP document provides a detailed summary of the assessment efforts and planned pollutant reduction strategies the BMAP task force developed. According to the BMAP, Alachua County will be actively involved solely or as a partner in the following types of management actions:
1. Public Education;
2. Stormwater Permit Program;
3. Structural Stormwater BMPs;
4. Conservation / BMPs – Land Acquisition;
5. Bacteria “Hot Spot” Program;
6. Restoration and Water Quality Improvement; and
7. Special Studies and Planning actions.
Based on the BMAP, there is a need for the County to allocate resources to meet the intent of the BMAP document. This will include staff and funding resources to administer and implement the identified processes and projects. Refer to the May 2008 BMAP document for further details.

March 2010
The Santa Fe River BMAP process was initiated in November 2009. During the process of BMAP development, it is expected that many of the same types of water quality pollutant reduction targeting projects and management actions will be identified which will also require implementation. The Santa Fe River BMAP will also be distinct in several ways in that it will have numerous different stakeholders affected as well as more of a focus on protecting groundwater resources from impacts by surface water. Similar to the Orange Creek BMAP, Alachua County will have an allocation of responsibility to implement management actions.
In order to effectively manage the County’s stake in these BMAPs, and to insure that the management actions are carried out in a proactive and responsive manner, additional administrative staff resources are necessary. Supporting project funding would also be necessary to implement some of the management action objective.
Implementation of the recommendations of the current Orange Creek BMAP and future Santa Fe River BMAP represents a need that Alachua County should address. To address this need, additional staff and project funding resources would be required beyond what the County currently has allocated.
