Understanding Your Franklin County Aquifer Water Source
Water in Franklin County, Vermont, often comes from groundwater in aquifer 112SRFD. This groundwater moves through underground layers before reaching household taps. The natural composition of this water includes various dissolved substances, among them nitrate.
How Treated Water Differs at the Tap
Reduction of Nitrate Concentration
The C-Series Nitrate & Nitrite (Well) Filter targets nitrate and nitrite compounds, reducing their levels as water flows through the system. This treatment helps adjust water quality to meet household preferences or concerns related to nitrate presence.
Maintained Water Clarity and Taste
By focusing on nitrate and nitrite removal, the filter leaves most other aspects of water composition unchanged, preserving the water’s original clarity and taste characteristics.
Fixtures and Appliances Affected First
Kitchen and Drinking Water Faucets
Fixtures that provide water for consumption, such as kitchen faucets and drinking water dispensers, are primarily affected. Reducing nitrate here is important due to ingestion concerns.
Water Used in Food Preparation
Water used in cooking or preparing beverages benefits from nitrate reduction to control potential intake levels during household activities.
Information to Gather Before Seeking Treatment Advice
Your Household Water Use Patterns
Document how water is used daily, especially for drinking and cooking, to determine the volume and flow rates needed for treatment.
Recent Water Testing Results
Obtain a recent, certified laboratory test specific to your well or water source for nitrate concentration. This personal data is essential for accurate treatment guidance.
Existing Water System Configuration
Note your current household water setup, including any filters or treatment devices, to evaluate integration with additional nitrate treatment.
Interpreting Detected, Median, and Range in This Sampling Record
Detected Means Presence, Not Exceedance
All four nitrate measurements in this Franklin County aquifer were detected, showing nitrate is present but below any federal health thresholds.
Median Represents Typical Concentration
The median nitrate level of 0.745 mg/L suggests the common concentration found in these samples taken over nearly a decade.
Range Indicates Variation Over Time and Location
Measured nitrate values ranged from 0.206 to 2.56 mg/L in the sampled wells, demonstrating some variation in the aquifer’s nitrate presence but always below regulatory concern limits.
Why Aesthetic Secondary Standards Differ From Health-Based Limits for Nitrate
Secondary Standards Focus on Taste and Appearance
Standards related to water aesthetics address taste, odor, or staining potential. For nitrate, these secondary thresholds are not health-based but relate to consumer perception.
Health-Based Limits Govern Consumption Safety
The federal nitrate limits protect health by setting maximum allowable concentrations for ingestion. This aquifer's monitored values do not exceed those health limits.
Additional Considerations for Commercial or Industrial Operations
Higher Volume Water Use
Commercial or industrial users must consider treatment solutions that accommodate larger water volumes and varying flow rates compared to residential use.
Regulatory Compliance Beyond Household Standards
Operations may face additional regulatory or monitoring requirements for nitrate beyond household concerns, necessitating more complex treatment approaches.
Process-Specific Water Quality Needs
Certain industrial processes may require nitrate levels maintained within stricter tolerances to avoid affecting product quality or equipment performance.

Where this information comes from
Source: USGS groundwater sampling. Sampled 2023-07-20. 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.
On record: U.S. Geological Survey sampling of Nitrate in the 112SRFD aquifer (Franklin County): 4 results from 1 wells, median 0.745 mg/L, range 0.206-2.56 mg/L; none above any federal threshold
