The Hidden Threat: How Lake Apopka’s Contaminated Past Continues to Impact Montverde Well Water Quality

For decades, homeowners in Montverde, Florida, have drawn their drinking water from private wells, trusting that the groundwater beneath their properties provides clean, safe water for their families. However, the proximity to Lake Apopka—once known as “Florida’s most polluted large lake”—creates unique challenges that many residents may not fully understand. The complex relationship between surface water contamination and groundwater quality means that even properties miles away from the lake’s shores can experience water quality issues stemming from decades of agricultural pollution and industrial contamination.

Lake Apopka’s Contamination Legacy

Lake Apopka’s transformation from a world-class fishing destination to an environmental disaster didn’t happen overnight. Historically, more than 85 percent of the phosphorus going into Lake Apopka was from farms on the lake’s north shore. To combat this problem, the District and the U.S. Department of Agriculture (USDA) purchased almost all of the farms for restoration between 1988 and 2001. This contributed to reducing discharges of excessive nutrients from farms to the lake. The damage, however, extended far beyond visible algae blooms and fish kills.

The soil inversion process was developed as a remediation method to address the high levels of organochlorine pesticides (OCPs) found in organic surface soils (the top 30 centimeters (cm) of soil). The pesticides remain in the organic soils from years of farm pesticide applications. The inversion process used modified farm equipment to plow up to one meter deep and essentially flip the soil, bringing up uncontaminated soil to the surface and covering the contaminated surface layer of soil. The work was completed in May 2009 and it helped ensure that OCPs were unable to enter the food chain.

The Groundwater Connection

What many Montverde residents don’t realize is how interconnected their well water is with the broader watershed system. Unfortunately, aquifer water is easily contaminated because of Florida’s unique soil layer, high water table, porous limestone, and large quantities of rainfall. According to the EPA, polluted groundwater can reach drinking water systems and pose serious public health threats, particularly to children and young adults. Chemicals from various manufacturers and microbial contaminants can quickly enter the state’s aquifer water.

The Tower Chemical Company site, located near Lake Apopka’s headwaters, provides a stark example of how industrial contamination can affect groundwater quality over vast areas. From 1957 to 1980, Tower Chemical Company manufactured and stored various pesticides at the site. In its early years of operation, the company burned and buried waste in a 1.5-acre area and discharged wastewater into a 0.5-acre unlined pond. As a result, wastewater seeped down through the soil into the Floridan Aquifer. In 1980, the wastewater pond overflowed into an on-site drainage ditch and then flowed downstream into the Gourd Neck of Lake Apopka, affecting vegetation and animals.

Current Water Quality Challenges in Montverde

Even as Lake Apopka undergoes extensive restoration efforts, the legacy of contamination continues to affect local groundwater. Montverde, Florida serves 800 people with data available from 2014-2019 using groundwater sources, with 4 contaminants exceeding EWG health guidelines out of 9 total contaminants. Legal does not necessarily equal safe. Getting a passing grade from the federal government does not mean the water meets the latest health guidelines. Legal limits for contaminants in tap water have not been updated in almost 20 years.

The most concerning contaminants found in Florida’s groundwater include dry-cleaning solvents, gasoline leaking from storage tanks, and various pesticides as the three most common aquifer contaminants. Additionally, pesticides such as ethylene dibromide (EDB) have been detected in water wells within citrus growing areas, and other rural areas of the state.

Testing and Treatment Recommendations

The Florida Department of Health emphasizes that testing is the only way to know for sure that the water you are drinking from your well is safe. Regular testing becomes even more critical in areas like Montverde, where proximity to historical contamination sources creates ongoing risks.

When contamination is detected, the well typically can be remediated to meet drinking water quality standards by installing a granular activated carbon filtration system or other type of filtration system. However, the specific treatment approach should be tailored to the contaminants present, which is why professional water analysis and custom system design are essential.

Moving Forward with Confidence

While Lake Apopka’s restoration continues to show promising results—since the late 1980s, phosphorus concentrations have declined 69% and water clarity increased 93%, as of the end of 2023—the legacy of contamination means that nearby communities like Montverde must remain vigilant about their groundwater quality.

The good news is that with proper testing, treatment, and ongoing maintenance, Montverde residents can enjoy safe, clean water regardless of their proximity to Lake Apopka. By working with experienced water treatment professionals who understand the local contamination risks and regulatory requirements, homeowners can protect their families’ health while contributing to the broader environmental recovery of the region.

Understanding the connection between Lake Apopka’s contaminated past and current groundwater quality empowers Montverde residents to make informed decisions about their water treatment needs. With the right filtration system and regular monitoring, clean, safe water remains achievable for every household in the community.
