At your kitchen tap, you might notice a faint chemical taste or worry about nitrate content, but without testing, severity is unclear. In FIPS 180, Connecticut, information from government studies can help you understand what nitrate levels have been found in groundwater drawn from aquifer 112DFSF.
Which Residential Fixtures and Processes Show Nitrate Effects First
Drinking water taps indicate nitrate concentration most directly
Water used for drinking and cooking delivers nitrate directly to residents and is the first point where nitrate presence is relevant.
Water used in infant formula preparation deserves special caution
Nitrate can pose particular risks to infants, whose sensitivity to elevated nitrate levels requires attentive water quality assessment.
Water for garden irrigation absorbs nitrate but does not directly impact residents
While plants can take in nitrate, this typically presents no direct health concerns for household members.
How Water Quality Changes After Using the C-Series Nitrate & Nitrite (Well) Filter
Tap water nitrate concentrations can be significantly lowered
The C-Series System filters nitrates and nitrites out, reducing their concentration in water from private wells.
Water clarity and taste may improve with reduced nitrate presence
Lower nitrate levels can translate into neutral or improved taste and reduced chemical indications.
Filtration does not alter other natural minerals or water hardness significantly
The treatment targets nitrates specifically, leaving most mineral content unchanged.
Scope and Size of Government Sampling Behind These Nitrate Figures
Data comes from 20 separate wells sampled 398 times across FIPS 180 aquifer 112DFSF
The extensive sample set offers a broad view rather than an individual well test.
Wells sampled varied from 10 to 80 feet deep
This depth range covers typical residential well depths, providing relevant context.
Sampling dates from March 2010 through November 2025
Long-term data helps describe trends and variability in nitrate levels over time.
Interpretation Differences: Public-System Records vs Private Well Testing
Public data reflects area-wide aquifer conditions, not specific household wells
Government sampling provides a regional overview, but your home's nitrate levels depend on your specific well and conditions.
Private well testing is necessary to determine nitrate concentration at your tap
To know precisely whether nitrate levels in your household water exceed health-based thresholds, personal well water testing is essential.
Public data identifies potential concerns but does not dictate individual well safety
Detecting nitrate in the aquifer is informative for planning but is not a definitive statement about your home's water.
Meaning of Measured Nitrate Ranges and Federal Health Standards
Median nitrate found was 6.23 mg/L, ranging from 0.456 to 112.0 mg/L
This variability indicates some locations have nitrate well below the federal maximum contaminant level (MCL) while others exceed it.
149 of 398 samples were above the federal MCL of 10.0 mg/L
This federal MCL marks the health-based threshold for nitrate concentration in drinking water.
Detection alone is not a health violation; your well’s specific level must be tested
Presence of nitrate measured in an area is not the same as a confirmed health risk in every household.
This checklist reviewed what nitrate data from aquifer 112DFSF in FIPS 180, CT, reveals for households. Understanding that government sampling offers a broad context, individual well testing is necessary to assess your home's water. When elevated nitrate is present, using a C-Series Nitrate & Nitrite (Well) Filter can effectively reduce it for safer, more pleasant water at the tap.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-11-21. 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 112DFSF aquifer (FIPS 180): 398 results from 20 wells, median 6.23 mg/L, range 0.456-112.0 mg/L; 149 above a health-based federal MCL (federal MCL 10.0 mg/L)
