The U.S. Geological Survey sampled groundwater from Flagler County aquifer wells in November 2019, measuring total dissolved solids (TDS) in water from three wells drilled 100 to 120 feet deep. These nine results showed TDS values ranging from 0.51 to 397.0 mg/L, with a median concentration of 375.0 mg/L. None of these measurements exceeded applicable federal limits for drinking water, indicating no regulatory health concern from TDS in the area aquifer samples.
Seasonal and Multi-Year Variation Reflected in Area TDS Sampling
The sampling record captures a short time snapshot over two days, so it does not directly measure seasonal or yearly TDS changes. However, the range of values suggests that natural variations occur in this aquifer. Factors like rainfall, aquifer recharge, and water table depth likely influence TDS concentrations over time. Prospective well users should be aware that TDS in their own water might vary somewhat outside this range depending on conditions and specific well depth.
Essential Water Data to Record Before Seeking Treatment Guidance
Accurate treatment sizing begins with well-specific water quality data. Residents should obtain laboratory analysis for TDS and related water chemistry from their own well samples. Details such as well depth, flow rate, and historical water quality reports aid in selecting a treatment system that matches the well’s unique profile. Documenting household water usage also helps define capacity requirements.
First Impacts: Household Fixtures and Appliances Sensitive to Dissolved Solids
Water with elevated TDS can affect appliances and fixtures over time. For example, water heaters, dishwashers, and coffee makers may accumulate scale or experience reduced efficiency. Faucets and showers might show mineral deposits. These aesthetic and operational impacts typically occur before any health-related concerns and can influence maintenance needs and equipment lifespan.
Stepwise Approach to Identify Water Quality Issues
Homeowners should start with basic checks like observing water taste, clarity, and any visible deposits. Measuring flow rate and pressure ensures the well and plumbing are functioning properly. Next, submitting water samples to an accredited lab for detailed analysis confirms the presence and levels of TDS along with other constituents. This approach helps rule out plumbing problems or temporary conditions before pursuing treatment.
Comparing Flagler County TDS Levels to Adjacent Areas Without Overinterpretation
Variations in groundwater chemistry between counties can occur due to differences in geology, land use, and hydrology. When comparing Flagler County data to a neighboring county, it is important to note differences in sample sizes, well depths, and sampling dates. Without well-specific tests, it is not appropriate to infer individual water quality or treatment needs solely from regional comparisons.
Understanding TDS Origin in Flagler County Groundwater
Total dissolved solids in this region originate from natural mineral deposits dissolving into the aquifer and potentially from human activities such as agricultural runoff. The local limestone geology can contribute calcium and magnesium salts, which affect water composition. Recognizing these sources helps in selecting a treatment that addresses the specific mineral content effectively.
To determine the correct sizing for a treatment system, ordering a comprehensive water test covering TDS and other key parameters is the recommended first step. Knowing the exact concentrations in your well water will allow you to choose a system with appropriate capacity and functionality. A well-matched solution ensures effective water conditioning and protection of household appliances and plumbing.
