How Many Samples and Wells Stand Behind the Figures, and What a Small Sample Means
The water hardness data for Grafton County's aquifer 112SRFD comes from three separate wells sampled by the U.S. Geological Survey during June and July of 2017. Each well was between 73 and 174 feet deep. While this data offers a snapshot of conditions in the area, three samples represent a small data set and cannot define your home's specific water quality. Variation between wells and over time means individual household water may differ.
What 'Detected', 'Median' and 'Range' Mean in the Sampling Record on This Page
Hardness, measured as milligrams per liter of calcium and magnesium, was detected in all three samples. The median hardness was 82.7 mg/L, with a range from 31.1 mg/L to 129.0 mg/L. 'Detected' means the constituent was measured above the instrument’s threshold. 'Median' is the middle value among the three results, representing a typical reading for the sampled wells. 'Range' indicates the lowest and highest values found. None of these results exceeded any federal limits, confirming no health-based violations were found in the samples.
What a Certified Laboratory Test for This Constituent Reports and How to Read It
A certified laboratory testing your home water for hardness will provide a concentration value similar to these area samples, expressed in milligrams per liter as calcium carbonate equivalent. This figure reflects the total dissolved calcium and magnesium that can affect laundry appearance. Comparing your home's test result against the area's median and range helps determine if your water hardness lies within typical local variation or requires special attention.
How Seasonal or Multi-Year Variation Shows in the Record (Dates and Ranges Given)
These three samples were collected within a five-week span in summer 2017. Seasonal shifts in groundwater chemistry can occur, so water hardness might fluctuate above or below this snapshot. However, without longer-term or repeated testing, it's unclear how much hardness varies year-round in Grafton County’s aquifer 112SRFD specifically. A one-time home test offers the best insight into your current water condition.
How to Judge Treatment Capacity Against the Household’s or Facility’s Daily Demand
When considering treatment options to address faded laundry, knowing the volume of water used daily is essential. Treatment systems vary in capacity to handle water hardness and the flow rate through them. To select a solution that matches your family’s demand, calculate your average daily water consumption and compare it with the system’s specifications provided at the time of quoting. This ensures sufficient treatment effectiveness without oversizing.
Closing: To restore the vibrancy of your laundry and manage the effects of hardness typical for Grafton County’s aquifer 112SRFD, the C-Series Faded, Stiff Laundry System ships ready to configure to meet your household’s daily water needs, based on your water test and usage. Requesting a quote helps to tailor the solution accurately for your conditions.
