Nutrient overload, or eutrophication, is one of the most serious water quality problems facing the river and its tributaries. Fecal coliform bacteria are microorganisms associated with the intestinal tract of warm-blooded animals.
Central Florida is already reaching the sustainable limits of its predominant source of water, the Floridan Aquifer. In 2015, the CFWI released water supply plans that include projects that could remove up to 160 mgd of surface water from the St. Sedimentation, or construction-site runoff, is one of the most significant problem facing waterways throughout the St. Pressures from growth and development result in the significant degradation and loss of important aquatic and terrestrial habitat. For decades, our wetlands were thought of as worthless swamps and wastelands that must be drained and reclaimed in the name of economic progress. Nearly a century later, we now recognize the value and importance of wetlands to water quality, fish and wildlife, and to us as humans.
Pollutants that are deteriorating the water quality and the health of humans and aquatic wildlife include heavy metals, such as mercury, and organic compounds, such as PCBs and dioxin.
Unfortunately, the Army Corps of Engineers has consistently failed to provide a thorough analysis, accurately assess these environmental impacts, or require adequate mitigation to offset damage from the dredging project. On-site wastewater treatment systems (OWS) are a common means of wastewater treatment in coastal North Carolina, where the soils are sandy and groundwater is relatively close to the surface (<5 m).

PETRO-CLEAR For Hydrocarbons are live, synergistic blend of bacteria specifically chosen for their accelerated ability to metabolize heavy, tarry types of hydrocarbons, effective microbial remediation for gasoline, oil, fuels, diesel, hydraulic fluid and all varieties of aromatic compounds, pesticide spills and organic solvents. In our opinion, bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected microorganisms grown in the production laboratory. The bioremediation process is to provide an inoculum that will insure rapid bacterial growth.
PETRO-CLEAR For Hydrocarbons is a concentrated broad spectrum hydrocarbon degrader for soil remediation applications of coal tar, crude oil and mixtures of light and heavy oil fractions. Successful bioremediation of petroleum based products depends on a proper combination of nutrients, oxygen, and microbes.
While facultative anaerobes may function in the presence or absence of oxygen, aerobic activity is the preferred method for many contaminants. Oxygen release components, such as calcium peroxide or hydrogen peroxide, can be mixed directly in soil to supply oxygen for remediation in applications. The Centers For Disease Control (CDC)  completed a study of public pools during last summer’s swimming season and found that public pools are often contaminated with feces by the swimmers themselves.  Researchers at CDC found bacteria in samples of pool filter water collected from public pools. Change diapers in the bathroom or diaper-changing area and not at poolside where germs can rinse into the water. The EPA recommends testing of private well water for coliform bacteria at least once per year. Easy to read, packed with 165 pages of useful how to guides, diagrams, charts and pictures.
The tributaries to the river often contain dangerous levels of fecal coliform from failing septic tanks, wastewater treatment plants, broken sewer lines, and animal waste. This degradation or loss of habitat results in the reduction of the biological productivity of the river and can ultimately lead to a river with little fish and other life forms. In the early 1900s, a network of canals, ditches, and levees were built in an effort to drain the wetlands that formed the headwaters of the St. These pollutants enter our waterways from many sources, including industrial wastewater discharges and air pollution. Wastewater contains elevated concentrations of pathogenic microorganisms that can contaminate groundwater and surface water if OWS are not operating efficiently and distributing wastewater equally to all drainfield trenches. IntroductionOn-site wastewater treatment systems (OWS) are a common method of wastewater treatment in many countries including the United States, Australia, Canada, New Zealand, and Ireland [1,2,3,4,5]. The blue circles show monitoring wells, (DG) is down-gradient wells, the red boxes show the boundaries of drainfields 1 and 2. The blue circles show the location of monitoring wells, the red boxes show drainfields 1 and 2. Groundwater Characterization and AnalysisEnvironmental readings and water samples were collected bi-monthly (4 times) during the study period (November 2012 to May 2013) from each well, septic tank, and adjacent surface water. Microbial TreatmentThe OWS at JWS was efficient (>99%) at reducing all FIB concentrations before discharge to groundwater and adjacent surface water. Smith (a) and West Craven High (b) for background groundwater (BG), septic tank effluent (Tank), groundwater beneath the drainfield with the highest microbial concentrations (F1-All), down-gradient groundwater (DG), spring water (Spring) and stream (Up-stream).


As the project progresses the population of petrophillic organisms will show up to a one thousand fold increase as they digest the contaminants. This formula, which also successfully degrades alcohols, ketones, and phthalates, rapidly degrades all major components of gasoline, diesel, #4, #5, & #6 fuel oils.
Often the limiting factor of aerobic degradation of contaminants is the availability oxygen . When bacteria have available oxygen, and hence function aerobically, they produce roughly eighteen times as much energy as anaerobic activity yields. Johns River by addressing and resolving the following issues that are impacting its health.
Johns River Water Management District (SJRWMD), South Florida Water Management District and Southwest Florida Water Management District - created the Central Florida Water Initiative (CFWI) to identify alternative sources of water to meet demand.
Soil leaving construction sites is burying aquatic life, disrupting the food chain, degrading water quality, and adversely impacting our recreational opportunities. Pollutants can be found in the sediments at the bottom of the river and often make their way into the food chain.
The objectives of this study were to compare the distribution of fecal indicator bacteria (FIB) in groundwater beneath a large low-pressure pipe (LPP) OWS and a large pump to distribution box system, and to determine the effectiveness of the systems in reducing FIB including total coliform, E. OWS treat wastewater that contains high concentrations of pathogenic microorganisms such as bacteria, viruses, and protozoa [1,6]. The fronts of the drainfields are located on the west side of the boxes, while the ends of the drainfields are located on the east side of the boxes. The fronts of the drainfields are located on west side of the boxes, while the ends of the drainfields are located on the east side of the boxes. Samples were collected during periods without rainfall to help reduce the potential for sample contamination. Data indicate excellent treatment (>99% reduction) for all indicator bacteria from the septic tanks to groundwater, and further treatment as indicator bacteria concentrations decrease in groundwater down-gradient from the systems.
Data indicate higher mean specific conductivity values for groundwater influenced by wastewater. Microbial activity is most frequently limited by insufficient oxygen due to slow rates of diffusion into the interior of the soil layers or piles and into the center of soil aggregates. Johns River system is threatened due to years of neglect and the cumulative impacts of a growing population.
More than 70 percent of the marsh was converted into agricultural lands and urban development. Many fish species are unsafe for consumption because of the high level of pollutants in their tissues. This increase in salinity will likely damage or destroy hundreds of acres of wetlands, submerged grasses, and trees in parts of the river and its tributaries, such as Julington Creek and Ortega River.
Most OWS include a septic tank, effluent distribution device, drainfield trenches, and soil beneath the trenches.
The depth to groundwater at each well was determined using a Solinst TLC meter (Solinst, Ontario, Canada). Data indicate that groundwater enterococci concentrations were significantly higher near the ends of the trenches relative to fronts of the trenches at James Smith, and beneath Field 1 relative to Field 2 at James Smith and West Craven.
Data indicate that groundwater coliform concentrations were evenly distributed beneath the systems at both sites.
Generally, the greater the mass of oxygen that can be distributed the more rapid and complete the cleanup.
Since Florida's inception as a state, we have drained and filled approximately half of our wetlands. Critical habitat for fisheries and pollution filters for our river will be lost in the process. Monitoring wells were installed at the fronts and ends of the drainfields for sample collection.
The septic tank provides primary treatment via sedimentation and anaerobic digestion of organic matter.
Once the wells were placed and driven in the boreholes, the annular space adjacent to the screen was filled with sand, and the annular space above the screen was filled with a mixture of native sand and bentonite. The well was then purged using a sterile (unwrapped immediately prior to use) bailer, allowed to recharge, and a sample was transferred from the bailer to sterile sample bottle.
When these waters are used as sources of drinking water and the water is not treated or inadequately treated, E. The effluent distribution device distributes wastewater to the drainfield trenches, where effluent is stored until infiltrating the soil.
The soil beneath the drainfield trenches provides most of the physical, chemical and biological treatment of wastewater.
The relative elevation of the monitoring wells was determined using a laser level, and the coordinates of the wells were determined using a Trimble 6000 series GPS (Trimble Navigation Limited, Westminster, CO, USA). Sample bottles were labeled and placed in ice filled coolers for later transport to the East Carolina University Environmental Health Sciences Water Laboratory for analysis.


Other types of bacteria can be found in well water also, such as slime and odor producing iron and sulfur bacteria. Both systems were effective (>99%) at reducing FIB concentrations before discharge to groundwater. If OWS do not reduce the concentration of pathogens in wastewater effluent, then groundwater and surface water quality may be degraded and public health may be compromised. Site maps with the monitoring well locations overlain on aerial photographs were created for both sites. Results indicate that the LPP did enhance the distribution of FIB in groundwater beneath the drainfield area relative to the pump to distribution box system. For example, studies have shown that concentrations of fecal indicator bacteria (FIB) including E.
Depth to groundwater was determined using a Solinst TLC meter (Solinst, Ontario, Canada), and the relative elevation of the groundwater was labeled on the maps. Although the LPP system had a vadose zone over 2 m thinner than the pump to distribution box system, FIB treatment was similar. Groundwater flow direction was determined using the groundwater data, and the 3-pt contouring method [24].
An YSI 556 multi-meter (YSI Inc., Yellow Springs, OH, USA) was used to determine sample pH, specific conductivity (SC), and temperature in the field.
Other research has shown that surface water FIB concentrations were elevated in areas adjacent to high densities of OWS [11] and when groundwater levels beneath OWS were elevated surface water FIB concentrations were also elevated [12]. Monitoring wells were installed up-gradient and down-gradient from the systems at both sites, after the groundwater flow direction was determined. High densities of OWS have been associated with endemic diarrheal illness, with higher OWS densities correlating to higher incidences of bacterial and viral diarrhea in a study in central Wisconsin [13].Other factors associated with OWS wastewater treatment performance include soil type, loading rates, and system type. Septic effluent samples were obtained from the distribution box at JWS and from the septic tank at WCH by removing the manhole covers and lowering bailers into the box and tank for sample collection. OWS installed in soils with higher percentages of fine-textured materials such as silt and clay, typically are more efficient at reducing microbial concentrations than OWS installed in sandy soils, due to the increased reactive surface area and residence time [7,14,15]. Research has also suggested that higher wastewater loading rates may lead to decreased treatment [8,16,17,18] and that OWS that utilize low pressure pipe (LPP) distribution can more efficiently treat wastewater constituents such as bacteria relative to gravity flow effluent distribution systems [16,19,20]. The ends of the laterals include a “turn-up” that is capped, so that when the pump is activated, the manifold and then all laterals should pressurize and thus deliver equal distribution of effluent across the drainfield. Septic effluent samples were diluted (dilution factors of 10–2000?) because of elevated FIB concentrations.
Effluent distribution with distribution boxes is facilitated by gravitational forces, not pressure, even if the OWS uses a pump. For quality control and assurance, field blanks were inserted for approximately 10% of samples. The conveyance pipes are not capped at the end, and thus often deliver more wastewater to the front of the trenches than an LPP system. Because some of the earlier studies suggested that LPP systems could perform better than conventional OWS [16,19,20], there are less stringent siting requirements for LPP systems relative to conventional systems with distribution boxes in North Carolina.
For example, in sandy areas, LPP systems can be installed in soils with 15 cm less soil depth and separation to groundwater than conventional OWS [21], and LPP systems typically require about 25%–30% less overall drainfield area than conventional trench systems with distribution boxes [21]. If LPP systems are more effective at distributing wastewater across the entire drainfield area than gravity flow distribution systems, then groundwater characteristics (as influenced by infiltrating wastewater) beneath the LPP systems may also be more homogeneous. However, there is a lack of field research that compares FIB groundwater quality uniformity beneath OWS that use LPP and gravity flow distribution. If the LPP systems are not more effective at distributing effluent across the entire drainfield area than OWS that use distribution boxes, then the overall treatment of wastewater constituents such as pathogenic microorganisms may not be as effective as prior work has suggested. Treatment EfficiencyFIB concentrations in septic effluent and groundwater beneath the drainfield with the highest FIB concentrations (Field 1 or Field 2 for each site) were compared to determine the effectiveness of the OWS in reducing FIB concentrations in the vadose zone.
Septic effluent concentrations of FIB were also compared to groundwater down-gradient and within the flow path of the OWS to determine the effects on groundwater quality down-gradient from the OWS. Groundwater FIB concentrations beneath the drainfield trenches and within the flow paths of the OWS were compared to up-gradient groundwater FIB concentrations to determine if the OWS were influencing groundwater quality.
Surface water was also sampled at JWS from a spring located down-gradient and within the groundwater flow path of the OWS, and from an adjacent stream that received the spring discharge. Groundwater and surface water FIB concentrations were compared to surface waters standards for the specific indicators. The geometric mean FIB concentrations we observed were not compared to the geometric mean FIB water quality standards for FIB because the sampling frequency used in this study did not conform to the frequency recommended by the US United States Environmental Protection Agency (EPA). The geometric mean FIB concentrations were instead compared to the single sample FIB standard for infrequently used surface waters suggested by the US EPA.
