Residents that rely on private wells for home consumption are responsible for ensuring the safety of their own drinking water. The Florida Department of Health (FDOH) recommends private well users test their water once a year for bacteria and nitrate.
Unlike private wells, public water supply systems in Florida are tested regularly to ensure that they are meeting safe drinking water standards.
Where can you have your well water tested?
Your best source of information on how to have your water tested is your local county health department. Most health departments test drinking water and they will let you know exactly what samples need to taken and ho w to submit a sample. You can also submit samples to a certified private lab near you.
Contact information for county health departments can be located at: http://www.floridahealth.gov/programs-and-services/county-health-departments/find-a-county-health-department/index.html
Contact information for private certified laboratories are found at https://fldeploc.dep.state.fl.us/aams/loc_search.asp
Why is it important to test for bacteria?
Labs commonly test for both total coliform bacteria and fecal coliforms (or E. coli specifically). This usually costs about $25 to $30, but can vary depending on where you have your sample analyzed.
- Coliform bacteria are a large, diverse group of bacteria and most species are harmless. But, a positive test for total coliforms shows that bacteria are getting into your well water. They are used as indicators – if coliform bacteria are present, other pathogens that cause diseases may also be getting into your well water. It is easier and cheaper to test for total coliforms than to test for a suite of bacteria and other organisms that can cause health problems.
- Fecal coliform bacteria are a subgroup of coliform bacteria found in human and other warm-blooded animal feces, in food and in the environment. E. coli are one group of fecal coliform bacteria. Most strains of E. coli are harmless, but some strains can cause diarrhea, urinary tract infections, and respiratory illnesses among others.
To ensure safe drinking water, FDOH strongly recommends disinfecting your well if the water tests positive for (1) only total coliform bacteria, or (2) both total coliform and fecal coliform bacteria (or E. coli). Disinfection is usually done through shock chlorination. You can either hire a well operator in your area to disinfect your well or you can do it yourself. Information for how to shock chlorinate your well can be found at http://www.floridahealth.gov/environmental-health/private-well-testing/_documents/well-water-facts-disinfection.pdf
Why is it important to test for nitrate concentration?
High levels of nitrate in drinking water can be dangerous to infants, and can cause “blue baby syndrome” or methemoglobinemia. This is where nitrate interferes with the blood’s capacity to carry oxygen. The Maximum Contaminant Level (MCL) allowed for nitrate in drinking water is 10 milligrams nitrate per liter of water (mg/L). It is particularly important to test for nitrate if you have a young infant in the home that is drinking well water or when well water is used to make formula to feed the infant.
If test results come back above 10 mg/L nitrate, use water from a tested source (bottled water or water from a public supply) until the problem is addressed. Nitrates in well water can come from fertilizers applied on land surfaces, animal waste and/or human sewage, such as from a septic tank. Have your well inspected by a professional to identify why elevated nitrate levels are in your well water. You can also consider installing a water treatment system, such as reverse osmosis or distillation units to treat the contaminated water. Before having a system installed, contact your local health department for more information.
In addition to once a year, you should also have your well water tested when:
- The color, taste or odor of your well water changes or if you suspect that someone became sick after drinking well water.
- A new well is drilled or if you have had maintenance done on your existing well
- A flood occurred and your well and/or septic tank were affected
Remember: Bacteria and nitrate are not the only parameters that well water is tested for. Call your local health department to discuss your what they recommend you should get the water tested for, because it can vary depending on where you live.
FDOH maintains an excellent website with many resources for private well users at http://www.floridahealth.gov/environmental-health/private-well-testing/index.html, which includes information on potential contaminants and how to maintain your well to ensure the quality of your well water.

The major goal of the Wakulla Springs Basin Management Action Plan (BMAP) is to reduce nitrogen loads to Wakulla Springs. Septic systems are identified as the primary source of this nitrogen. Photo: A. Albertin
A Basin Management Action Plan, or BMAP, is a management plan developed for a waterbody (like a spring, river, lake, or estuary) that does not meet the water quality standards set by the state. One or more pollutants can impair a waterbody. In Florida, the most common pollutants are nutrients (particularly nitrate), pathogens (fecal coliform bacteria) and mercury.
The goal of the BMAP is to reduce the pollutant load to meet water quality standards set by the Florida Department of Environmental Protection (FDEP). BMAPS are roadmaps with a list of projects and management action items to reach these standards. FDEP develops them with stakeholder input. Targets are set at 20 years, and progress towards those targets is assessed every five years.
It’s important to understand that a BMAP encompasses the entire land area that contributes water to a given waterbody. For example, the land area that contributes water to Jackson Blue Springs and Merritts Mill Pond (either from surface waters or groundwater flow) is 154 square miles, while the Wakulla Springs Basin covers an area of 1,325 square miles.
BMAPs in the Panhandle
There are 33 adopted BMAPS in the state, and 5 that are pending adoption. Here in the Panhandle, we have three adopted BMAPS. They are the Bayou Chico BMAP in Escambia County, the Wakulla Springs BMAP in Wakulla, Leon, Gadsden and small parts of Jefferson County, and the Jackson Blue/Merritts Mill Pond BMAP in Jackson County. All three are impaired for different reasons.
- Bayou Chico discharges into Pensacola Bay and is polluted by fecal coliform bacteria. The BMAP addresses ways to reduce coliforms from humans and pets, which includes sewer expansion projects, stormwater runoff management, septic tank inspections, pet waste ordinances and a Clean Marina and Boatyard program.
- Wakulla Springs Nitrate from human waste is the main pollutant to Wakulla Springs, and Tallahassee’s wastewater treatment facility and the city’s Southeast Sprayfield were identified as the main sources. Both sites were upgraded (the sprayfield was moved), greatly reducing nitrate contributions to the spring basin. The BMAP is focused on septic systems and septic to sewer hookups.
- Jackson Blue/Merritts Mill Pond Nitrate is also the primary pollutant to the Jackson Blue/Merritts Mill Pond Basin, but nitrogen fertilizer from agriculture is identified as the main source. This BMAP focuses on farmers implementing Best Management Practices (BMPs), land acquisition by the Northwest Florida Water Management District , as well as septic tanks, recognizing their nitrogen contribution to Merritts Mill Pond.
Once all the BMAPS are adopted, FDEP states that almost 14 million acres will be under active basin management, an area that includes more than 6.5 million Floridians.

How are residents living in an area with a BMAP affected? It varies by BMAP and specifically land use within its boundaries. For example, in BMAPs where nitrogen from septic systems are found to be a major source of nutrient impairment to a water body, septic to sewer hookups, or septic system upgrades to more advanced treatment units will be required in specific areas. In urban areas where nitrogen fertilizer is an important source, municipalities are required to adopt fertilizer ordinances. Where nitrogen fertilizer from agricultural production is a major source of impairment, producers are required to implement Best Management Practices to reduce nitrogen loads.
More information about BMAPS
For specific information on BMAPS, FDEP has an excellent website: https://floridadep.gov/dear/water-quality-restoration/content/basin-management-action-plans-bmaps All BMAPs (full reports with specific action items listed) can be found there, along with maps, information about upcoming meetings and webinars and other pertinent information.
Your local Health Department Office is the best resource regarding septic systems and any ordinances that may apply to you depending on where you live. Your Water Management District (in the Panhandle it’s the Northwest Florida Water Management District) is also an excellent resource and staff can let you know whether or not you live or farm in an area with a BMAP and how that may affect you.

Along the Chipola River in Florida’s Panhandle, farmers are doing their part to protect critical Shoal Bass habitat by implementing agricultural Best Management Practices (BMPs) that reduce sediment and nutrient runoff, and help conserve water.
Florida’s Shoal Bass
Lurking in the clear spring-fed Chipola River among limerock shoals and eel grass, is a predatory powerhouse, perfectly camouflaged in green and olive with tiger stripes along its body. The Shoal Bass (a species of Black Bass) tips the scale at just under 6 lbs. But what it lacks in size, it makes up for in power. Unlike any other bass, and found nowhere else in Florida, anglers travel long distances for a chance to pursue it. Floating along the swift current, rocks, and shoals will make you feel like you’ve been transported hundreds of miles away to the Georgia Piedmont, and it’s only the Live Oaks and palms overhanging the river that remind you that you’re still in Florida, and in a truly unique place.
Native to only one river basin in the world, the Apalachicola-Chattahoochee-Flint (ACF) River Basin, habitat loss is putting this species at risk. The Shoal Bass is a fluvial specialist, which means it can only survive in flowing water. Dams and reservoirs have eliminated habitat and isolated populations. Sediment runoff into waterways smothers habitat and prevents the species from reproducing.
In the Chipola River, the population is stable but its range is limited. Some of the most robust Shoal Bass numbers are found in a 6.5-mile section between the Peacock Bridge and Johnny Boy boat ramp. The Florida Fish and Wildlife Conservation Commission has turned this section into a Shoal Bass catch and release only zone to protect the population. However, impacts from agricultural production and ranching, like erosion and nutrient runoff can degrade the habitat needed for the Shoal Bass to spawn.

Shoal Bass habitat conservation and BMPs
In 2010, the Southeast Aquatic Resources Partnership (SARP), the National Fish and Wildlife Foundation and a group of scientists (the Black Bass Committee) developed the Native Black Bass Initiative. The goal of the initiative is to increase research and the protection of three Black Bass species native to the Southeast, including the Shoal Bass. It also defined the Shoal Bass as a keystone species, meaning protection of this apex predators’ habitat benefits a host of other threatened and endangered species.
Along the Chipola River, farmers are teaming up with SARP and other partners to protect Shoal Bass habitat and improve farming operations through BMP implementation. A major goal is to protect the river’s riparian zones (the areas along the borders). When healthy, these areas act like sponges by absorbing nutrients and sediment runoff. Livestock often degrade riparian zones by trampling vegetation and destroying the streambank when they go down to a river to drink. Farmers are installing alternative water supplies, like water wells and troughs in fields, and fencing out cattle from waterways to protect these buffer areas and improve water quality. Row crop farmers are helping conserve water in the river basin by using advanced irrigation technologies like soil moisture sensors to better inform irrigation scheduling and variable rate irrigation to increase irrigation efficiency. Cost-share funding from SARP, the USDA-NRCS and FDACS provide resources and technical expertise for farmers to implement these BMPs.

By working together in the Chipola River Basin, farmers, fisheries scientists and resource managers are helping ensure that critical habitat for Shoal Bass remains healthy. Not only is this important for the species and resource, but it will ensure that future generations can continue to enjoy this unique river and seeing one of these fish. So the next time you catch a Shoal Bass, thank a farmer.

If you have not seen the news yet, the US Supreme Court provided a ruling on June 27, 2018 regarding the decades-long conflict between Florida and Georgia over water use in the Apalachicola-Chattahoochee-Flint tri-state river basin. Guess what; the battle continues. Following the previous findings of the court-appointed Special Master and his recommendation to deny Florida relief in the dispute, there were many disappointed people south of the border between the two states. The recent decision to remand the case back to the Special Master for further consideration has taken many by surprise; happy surprise south of the border and not so happy as you look northward (unless you talk to the attorneys litigating the case, maybe).
The resulting decision kept Florida’s hopes alive for an equitable allocation of water resources in the basin that spans nearly 20,000 square miles of the Southeastern US. At stake, from Florida’s perspective, is the productivity and ecosystem integrity of the Apalachicola River and Bay ecosystem. For Georgia, enough water to supply its growing population and thirsty agricultural interests in the Flint River Basin south of Atlanta.
The Court’s 5–4 decision, found that the Special Master had applied too high a standard regarding “harm and redressability” for Florida’s claims. They ordered the case to be reheard so that appropriate considerations could be given to Florida’s arguments. “The amount of extra water that reaches the Apalachicola may significantly redress the economic and ecological harm that Florida has suffered,” said Justice Breyer, who was joined by Chief Justice John Roberts and Justices Anthony Kennedy, Ruth Bader Ginsburg and Sonya Sotomayor. “Further findings, however, are needed.”
The Court’s opinion does not actually outline any specific solutions for the water battle, and it in no way guarantees a win for Florida, but it does keep the legal challenge alive – along with the hope of better days for Florida’s oyster industry, which has suffered a major fisheries collapse that began around 2012. Visit this link if you would like to read the syllabus, as well as the full opinion of the High Court.
We should all consider the magnitude of the importance of the Apalachicola River and Bay for our region, due to its connection to the larger Gulf of Mexico. Estuaries like this are crucial links in the life-stages of countless marine organisms, including many we depend on for food and recreation. Blue crabs migrate tremendous distances to spawn in our near shore estuaries. Their young then disperse to populate large areas of coastline. Post-larval shrimp move into our estuaries to grow up after being spawned offshore. Later they swim out as adults to begin the cycle again. It is no wonder the shorelines of our Florida estuaries are dotted with prehistoric shell middens from peoples who thrived near these resource-rich ecosystems. Who knows if the Apalachicola Bay will ever recover to the productivity of its glory days, when a hard-working person could harvest 20 bags of oysters in a day? Regardless, we should all be thankful for what Apalachicola Bay has meant to so many generations of people over such a wide expanse of our Northern Gulf of Mexico coastline. Take just a moment to think about it, please.

With more than 250 crystal clear springs in Northwest Florida it is just a short road trip to a pristine swimming hole! Springs and their associated flowing water bodies provide important habitat for wildlife and plants. Just as importantly, springs provide people with recreational activities and the opportunity to connect with the natural environment. While paddling your kayak, floating in your tube, or just wading in the cool water, think about the majesty of the springs. They are the visible part of the Florida Aquifer, the below ground source of most Florida’s drinking water.
A spring is a natural opening in the Earth where water emerges from the aquifer to the soil surface. The groundwater is under pressure and flows upward to an opening referred to as a spring vent. Once on the surface, the water contributes to the flow of rivers or other waterbodies. Springs range in size from small seeps to massive pools. Each can be measured by their daily gallon output which is classified as a magnitude. First magnitude springs discharge more than 64.6 million gallons of water each day. Florida has over 30 first magnitude springs. Four of them can be found in the Panhandle – Wakulla Springs and the Gainer Springs Group of 3.
Wakulla Springs is located within Edward Ball Wakulla Springs State Park. The spring vent is located beneath a limestone ledge nearly 180 feet below the land surface. Archaeological evidence suggests that humans have utilized the area for nearly 15,000 years. Native Americans referred to the area as “wakulla” meaning “river of the crying bird”. Wakulla was the home of the Limpkin, a rare wading bird with an odd call.
Over 1,000 years ago, Native Americans used another first magnitude spring, the Gainer Springs group that flow into the Econfina River. “Econfina”, or “natural bridge” in the local native language, got its name from a limestone arch that crossed the creek at the mouth of the spring. General Andrew Jackson and his Army reportedly used the natural bridge on their way west exploring North America. In 1821, one of Jackson’s surveyors, William Gainer, returned to the area and established a homestead. Hence, the naming of the waters as Gainer Springs.
Three major springs flow at 124.6 million gallons of water per day from Gainer Springs Group, some of which is bottled by Culligan Water today. Most of the springs along the Econfina maintain a temperature of 70-71°F year-round. If you are in search of something cooler, you may want to try Ponce de Leon Springs or Morrison Springs which flows between 6.46 and 64.6 million gallons a day. They both stay around 67.8°F. Springs are very cool, clear water with such an importance to all living thing; needing appreciation and protection.

As hurricane season is upon us again, I wanted to share the results of work that UF/IFAS Extension staff did with collaborators from Virginia Tech and Texas A&M University to help private well owners impacted by Hurricanes Irma and Harvey last year. This work highlights just how important it is to be prepared for this year’s hurricane season and to make sure that if flooding does occur, those that depend on private wells for household use take the proper precautions to ensure the safety of their drinking water.
About 2.5 million Floridians (approximately 12% of the population) rely on private wells for home consumption. While public water systems are regulated by the U.S. Environmental Protection Agency to ensure safe drinking water, private wells are not regulated. Private well users are responsible for ensuring the safety of their own water.
Hurricanes Irma and Harvey
In response to widespread damage and flooding caused by Hurricane Harvey in Texas and Irma in Florida in August and September 2017, Virginia Polytechnic Institute and State University (VT) received a Rapid Research Response Grant from the National Science Foundation to offer free well water testing to homeowners impacted by flooding.
They partnered with Texas A&M AgriLife Extension’s Well Owner Network (run by Diane Boellstorff and Drew Gholson) and us, at UF/IFAS Extension to provide this service. The effort at VT was led by members of Marc Edward’s lab in the Civil Engineering Department: Kelsey Pieper, Kristine Mapili, William Rhoads, and Greg House.
VT made 1,200 sampling kits available in Texas and 500 in Florida, and offered free analysis for total coliform bacteria and E. coli as well as other parameters, including nitrate, lead, arsenic, iron, chloride, sodium, manganese, copper, fluoride, sulfate, and hardness (calcium and magnesium). Homeowners were also asked to complete a needs assessment questionnaire regarding their well system characteristics, knowledge of proper maintenance and testing, perceptions of the safety of their water and how to best engage them in future outreach and education efforts.
Response in the aftermath of Irma
Although the sampling kits were available, a major challenge in the wake of Irma was getting the word out as counties were just beginning to assess damage and many areas were without power. We coordinated the sampling effort out of Quincy, Florida, where I am based, and spread the word to extension agents in the rest of the state primarily through a group texting app, by telephone and by word of mouth. Extension agents in 6 affected counties (Lee, Pasco, Sarasota, Marion, Clay and Putnam) responded with a need for sample kits, and they in turn advertised sampling to their residents through press releases.
Residents picked up sampling kits and returned water samples and surveys on specified days and the samples were shipped overnight and analyzed at VT, in Blacksburg, VA. Anyone from nearby counties was welcome to submit samples as well. This effort complemented free well water sampling offered by multiple county health departments throughout the state.
In all, 179 water samples from Florida were analyzed at VT and results of the bacterial analysis are shown in the table below. Of 154 valid samples, 58 (38%) tested positive for total coliform bacteria, and 3 (2%) tested positive for E. coli. Results of the inorganic parameters and the needs assessment questionnaire are still being analyzed.

Of 630 samples analyzed in Texas over the course of 7 weeks post-Hurricane Harvey, 293 samples (47% of wells) tested positive for total coliform bacteria and 75 samples (2%) tested positive for E. coli.
What to do if pathogens are found
Following Florida Department of Health (FDOH) guidelines, we recommended well disinfection to residents whose samples tested positive for total coliform bacteria, or both total coliform and E. coli. This is generally done through shock chlorination by either hiring a well operator or by doing it yourself. The FDOH website provides information on potential contaminants, how to shock chlorinate a well and how to maintain your well to ensure the quality of your well water (http://www.floridahealth.gov/environmental-health/private-well-testing/index.html).
UF/IFAS extension agents that led the sampling efforts in their respective counties were: Roy Beckford – Lee County; Brad Burbaugh – Clay County; Whitney Elmore – Pasco County; Sharon Treen – Putnam and Flagler Counties; Abbey Tyrna – Sarasota County and Yilin Zhuang – Marion County.
We at IFAS Extension are working on using results from this sampling effort and the needs assessment questionnaire filled out by residents to develop the UF/IFAS Florida Well Owner Network. Our goal is to provide residents with educational materials and classes to address gaps in knowledge regarding well maintenance, the importance of testing and recommended treatments when pathogens and other contaminants are present.
Remember: Get your well water tested if flooding occurs
It’s important to remember that if any flooding occurs on your property that affects your well and/or septic system, you should have your well water tested in a certified laboratory for pathogens (total coliform bacteria and E. coli) and any other parameters your local health department may recommend.
Most county health departments accept samples for water testing. You can also submit samples to a certified commercial lab near you. Contact your county health department for information about what to have your water tested for and how to take and submit the sample.
Contact information for county health departments can be found online at: http://www.floridahealth.gov/programs-and-services/county-health-departments/find-a-county-health-department/index.html
You can search for laboratories near you certified by FDOH here: https://fldeploc.dep.state.fl.us/aams/loc_search.asp This includes county health department labs as well as commercial labs, university labs and others.
You should also have your well water tested at any time when:
- The color, taste or odor of your well water changes or if you suspect that someone became sick after drinking your well water
- A new well is drilled or if you have had maintenance done on your existing well
Testing well water once a year is good practice to ensure the safety of your household’s drinking water.
