Yes. St. Augustine’s drinking water meets federal and state drinking water standards. The city performs required testing for regulated contaminants, disinfectants, metals, and microbial contaminants.

St. Augustine water is generally considered moderately hard due to the region’s groundwater supply from the Floridan Aquifer. Groundwater in Northeast Florida commonly contains naturally occurring calcium and magnesium minerals, which can contribute to scale buildup on fixtures, spotting on dishes, dry skin, and reduced soap efficiency in some homes.

The water quality information provided by the City of St. Augustine does not list PFAS detections in the report sections provided. Like many Florida utilities, the city continues monitoring water quality under evolving EPA guidance and regulatory requirements.

While PFAS results were not included in the screenshots provided, many homeowners still choose reverse osmosis or whole-house filtration systems for additional peace of mind and broader contaminant reduction.

Yes. St. Augustine’s water report listed fluoride levels around 0.49 ppm. This level is within typical drinking water guidelines, but some homeowners prefer to reduce fluoride in their drinking water. Reverse osmosis is one of the most common options for reducing fluoride at the kitchen sink.

St. Augustine’s drinking water comes from groundwater wells. According to the city’s water quality report, one well draws from the Surficial Aquifer while seven wells draw from the Floridan Aquifer. These groundwater sources supply water to homes and businesses throughout the city.

The City of St. Augustine uses a low-pressure reverse osmosis and nanofiltration treatment plant, followed by aeration and free chlorine disinfection. The treatment facility is capable of processing approximately 6.5 million gallons of water per day.

The city also monitors disinfection byproducts including haloacetic acids (HAA5) and total trihalomethanes (TTHMs), which remained below EPA regulatory limits in the latest report.

Many St. Augustine homeowners choose water treatment systems to help address mineral content, chlorine taste, scale buildup, and overall drinking water quality. A water softener may help reduce hardness-related buildup on plumbing fixtures and appliances, while reverse osmosis or whole-house filtration systems can improve drinking water taste and reduce additional contaminants.

The City of St. Augustine performs routine monitoring and testing throughout its drinking water system to ensure compliance with federal and state standards. Testing includes inorganic contaminants, disinfectants, disinfection byproducts, lead, copper, and other regulated substances.

Recent lead and copper testing remained below EPA action levels. The city also tracks byproducts of the disinfection process such as HAA5 and TTHMs.
