Understanding the Local Aquifer and Water Delivery
Worcester County’s groundwater supply includes aquifer 300CRSLN, a key source for many residential wells. Water travels underground through this aquifer and into individual wells, eventually reaching household taps. The quality of water you receive depends on the composition of this aquifer and the well’s construction.
1. What the Measured Range Means Compared to Federal Standards, and What It Does Not Mean
Government sampling by the U.S. Geological Survey analyzed 158 groundwater samples from 45 wells in this aquifer between August and November 2018. Among these samples, iron was detected in 98 results with concentrations ranging from 10.2 to 34,800 micrograms per liter (µg/L). The median concentration was 185.5 µg/L.
Importantly, none of these results exceeded any federal health-based standards. This means iron presence is typical but not a safety violation. Iron levels may affect water’s appearance or taste, but detection alone is not a sign of unsafe water or legal noncompliance.
2. Reading the Record’s Median and Range as a Homeowner
As a homeowner considering treatment, note that the median value represents a middle point of all samples—half had higher iron, half had lower. The wide range shows there is variability across wells in the area. Your own well’s iron concentration requires laboratory testing to determine precisely.
This local data helps set expectations for possible water characteristics but does not substitute for a direct test of your water source.
3. The Role of Plumbing Material and Age, Separate from Source Water
Beyond the aquifer’s water quality, the materials and age of pipes and fixtures inside your home influence water characteristics. Older pipes may contribute additional metallic taste or stains, independently of source water content. Plumbing design can affect flow, contact time, and water appearance, all factors separate from well water composition.
4. How the Treated Water Differs at the Tap Once the Documented Technology Is in Place
The Autotrol Complete Well System uses media filtration technology rated at 32,000 grains capacity to address iron and related concerns. When configured with this system, water entering your home typically shows reduced discoloration and sediment associated with iron presence.
This treatment helps improve water clarity and limits staining on plumbing fixtures, without affecting water safety or natural mineral content.
5. Which Fixtures, Appliances, or Processes Are Affected First and Why
Iron-related staining commonly appears first on faucets, sinks, and tubs where water contact is visible. Appliances such as dishwashers and washing machines may show reddish-brown residue over time. Addressing iron presence with treatment like the Autotrol system focuses on these points to prevent buildup and maintain appliance appearance.
6. How Seasonal or Multi-Year Variation Shows in the Record (Dates and Ranges Given)
The USGS sampling took place from late summer to the end of fall in 2018. The documented range of iron concentrations reflects variability during this period and between different wells. Seasonal changes, recharge rates, and well depth can cause fluctuations in concentrations over time.
Understanding this variability encourages ongoing water testing to track changes specific to your well.
In summary, the government’s sampling of Worcester County’s aquifer 300CRSLN provides a broad view of iron presence in local groundwater, indicating typical concentrations without any federal threshold exceedance. The Autotrol Complete Well System ships ready to configure and targets these conditions to improve water clarity and reduce aesthetic effects. For precise treatment decisions, testing your own well water remains essential.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2018-11-08. 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.
