Understanding What a Certified Laboratory Test Reports for Your Well Water
When testing well water, certified laboratories measure specific substances and report concentrations in micrograms per liter (ug/L) or parts per million (ppm). For constituents like iron in well water, these tests indicate the amount detected within a sample but do not determine health risks or legal compliance on their own. It is important to note that a detection means the substance was found by the instruments; it is not a violation or proof of unsafety. Countrylevel or aquifer-level water quality reports provide background data but do not establish the conditions of your individual well.
Reading Hillsborough County's Aquifer 120FLRD Iron Data as a Homeowner
According to U.S. Geological Survey groundwater sampling of aquifer 120FLRD in Hillsborough County, iron was detected in 26 of 30 samples collected from 20 wells between 2010 and 2012. Concentrations ranged from as low as 3.5 ug/L up to 7,920 ug/L, with a median value of 237 ug/L. These samples represent a range of well depths from 29 to 299 feet. None of the results exceeded federal thresholds for iron, indicating the concentrations found fall within regulatory expectations for this area. As a homeowner, these figures give a general sense of variability in iron content across local wells but do not specify your own water condition.
What to Expect From Treated Water at the Tap With Complete Well Treatment Technology
Using the Autotrol Complete Well System, which handles up to 32,000 grains capacity, can help reduce iron and related water quality effects that might arise in wells from this aquifer. Treated water typically has fewer particles or discoloration associated with iron presence, improving appearance and taste. The system addresses iron through proven filtration and oxidation methods, delivering water that meets household needs. Keep in mind that water treated with this technology is configured to address your well’s conditions after proper water quality testing.
How Representative Are the Sample Size and Wells for Understanding Your Water Quality?
The reported data derive from 30 samples taken from 20 wells distributed throughout Hillsborough County’s aquifer 120FLRD. While this provides a solid overview of groundwater iron characteristics in the area, individual wells can differ significantly. Local geology, well depth, and construction influence water quality beyond regional figures. For reliable decision-making on treatment equipment, these broad statistics are a helpful starting point but must be supplemented by a direct test of your own well water.
The Influence of Plumbing Materials and Age on Your Water Quality
Water quality inside your home can be affected by the materials and age of your plumbing in addition to source water characteristics. Older pipes or certain metals may interact with groundwater differently, potentially impacting taste, clarity, or corrosion. Treatment systems like the Autotrol Complete Well System work on source water before it enters household plumbing, but any effects from plumbing should also be assessed separately. Planning for complete well water treatment considers both the source water data and the household plumbing environment.
Before selecting equipment, the essential step is to order a certified laboratory test for your own well water focusing on constituents of concern such as iron. A test report showing iron concentrations within the typical range found in Hillsborough County’s aquifer 120FLRD would support use of a comprehensive treatment system like the Autotrol Complete Well System. This single test will provide the clarity needed to make an informed choice tailored specifically to your household’s water quality.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2012-11-07. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
