What should I note before asking about treating hard water?
Before seeking water treatment advice, you should have a recent hardness test from your own water supply. Hardness is primarily due to calcium and magnesium ions dissolved in the water. Knowing your water's actual hardness level helps target any treatment effectively since regional data alone cannot specify your home's water condition.
How do calcium and magnesium enter groundwater in Miami-Dade County?
In Miami-Dade County, calcium and magnesium naturally dissolve into groundwater from the surrounding limestone and dolomite formations. These minerals vary in concentration depending on the depth and location of wells within the 112BSCNN aquifer. The water samples reported by the U.S. Geological Survey reflect these natural sources rather than contamination.
What changes should I expect in my tap water after using the Autotrol Hard Water System?
The Autotrol Hard Water System conditions water by reducing calcium and magnesium levels that cause hardness. Water treated by this system tends to prevent scale buildup on fixtures and appliances and can improve soap performance. While the system does not remove all minerals, it adjusts water hardness to levels that are less likely to impact your household systems and daily water use.
How many samples and wells provide the hardness data for Miami-Dade County?
The hardness data comes from 141 samples taken from 83 separate wells across Miami-Dade County between 2010 and 2023. These wells ranged in depth from 14 to 325 feet. This substantial dataset offers a broad view of water hardness variations within the county's 112BSCNN aquifer, though individual wells may differ.
Can I compare Miami-Dade County's hardness data with neighboring counties?
Comparing hardness levels with neighboring counties requires caution because geological conditions vary widely. Miami-Dade’s median hardness was measured at 233 mg/L with a range up to 7100 mg/L, reflecting local limestone geology. Adjacent areas may have different mineral content and aquifer characteristics, so regional data comparisons should focus on broad trends rather than precise predictions for your water.
How should I understand the median and range figures in the context of household water hardness?
The median hardness value of 233 mg/L represents the middle point of measured hardness in the area's wells, meaning half of the samples were above this level and half below. The range, from 201 mg/L to 7100 mg/L, shows variability due to different well depths and locations. For a homeowner, this means their water hardness could be near the median or significantly higher, emphasizing the need for direct testing of their specific water supply.
What should I not assume based on Miami-Dade County's hardness data?
You should not assume your household water matches the area’s median hardness or falls within the reported range without a direct test. The presence of hardness minerals is natural and detected levels do not imply any health risks or legal violations. Water quality can vary within a county, and only a sample of your home's water can determine the exact treatment needs. The Autotrol Hard Water System ships ready to configure to fit your home’s water conditioning requirements once you know your water’s specific hardness.

Source: USGS groundwater sampling. Sampled 2023-03-23. 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.
