Well water is generally untreated and unregulated, so private well owners in Jacksonville should be diligent about water testing. EPA standards for drinking water applies in municipal water districts, but they don’t extend to private wells. These wells might contain unhealthy levels of iron, nitrates, bacteria, and other contaminants. Municipal water quality can vary greatly across the United States. Factors such as the age of homes and buildings, their proximity to treatment facilities, the age of water pipes, and the source of the municipality’s water contribute to the overall quality of city water. Annual water quality reports issued by local water districts reveal the average results of water testing, and they don’t necessary depict the water quality of individual homes. Many Jacksonville homeowners choose to schedule water testing services from trusted water treatment specialists so that they can compare their results to their municipalities’ reports.
