Three Lakes Water Hardness & Quality Report (2026)

The Three Lakes Water Association (3LWA) delivers drinking water to residents in the Three Lakes community, located in Polk County, Florida. Their sole water source is groundwater drawn from wells that tap into the vast Floridan Aquifer System. This aquifer's water is processed at the association's dedicated treatment plant. Here, the raw water undergoes essential steps including filtration, chlorine disinfection, and stabilization before it enters the local distribution pipes. The Three Lakes utility does not use any surface water from reservoirs or rivers, relying entirely on the underground supply within the Peace River watershed.

The groundwater originates from the Floridan Aquifer System, a significant karst aquifer system. This aquifer is primarily composed of Eocene and Oligocene-age limestone formations, notably the Ocala Limestone and the Avon Park Formation. These rock layers are rich in calcium carbonate and dolomite, which are readily dissolved by percolating groundwater. This natural leaching process, common in Florida's limestone-dominated geology, enriches the water with dissolved calcium and magnesium, leading to its notably hard character. The aquifer's geology naturally imparts a mineral-rich profile to the water supply.

Such hard water can lead to considerable scale buildup within household appliances like water heaters, dishwashers, and coffee makers, potentially shortening their lifespan and reducing efficiency. You might also notice stiff laundry and stubborn deposits on faucets and fixtures, with soap scum forming more readily. To combat these effects, a whole-house water softener is highly recommended. Homeowners can also try regular descaling of appliances with vinegar or installing filters designed to inhibit scale. For laundry, consider using detergent boosters. The Three Lakes Water Association consistently meets EPA standards, with annual reports available on their website confirming compliance for primary contaminants.
