Government sampling by the EPA from 2013 to 2015 found chromium-6 present in Meriden Water Division’s public water system, which serves Berlin, Cheshire, Meriden, Southington, and Wallingford in New Haven County, CT.
Questions Commercial or Industrial Users Add Beyond Household Concerns
Water Volume and Flow Rates Needed
Large-scale water use requires understanding peak flow demands and ensuring treatment capacity supports industrial processes.
Regulatory Compliance Complexity
Businesses must consider specific regulations that apply to their operation type, beyond residential water quality monitoring.
Impact on Equipment and Processes
Chromium-6 can interact with industrial equipment in ways that household plumbing does not experience.
Fixtures, Appliances, or Processes Impacted First in a Household
Water Softeners and Filtration Units
These are often the first points where chromium-6 is noticeable due to scale buildup or filter clogging.
Drinking Water Faucets
Chromium-6 presence may be more relevant here for direct ingestion considerations.
Appliances That Use Water Internally
Dishwashers and ice makers may accumulate deposits or be affected in water quality.
Household Symptoms That Do and Do Not Suggest Chromium-6 Presence
Symptoms Possibly Linked to Chromium-6
- Metallic or unusual taste in tap water
- Color changes in water after standing
- Deposits on fixtures or inside appliances
Symptoms Unrelated to Chromium-6
- Cloudy or milky water caused by air bubbles
- Odors not related to metals, such as chlorine smell
- Discoloration from rust or sediment
How Treated Water Differs at the Tap With the C-Series Chromium-6 Filter
Reduction of Chromium-6 Presence
The filter is designed to lower chromium-6 levels measured in the local system, improving water quality at consumption points.
Improved Taste and Appearance
Use of the filter can diminish metallic tastes and reduce visible water deposits.
Ready to Configure Delivery
The C-Series Chromium-6 Filter ships ready to configure within household plumbing setups, supporting ease of adaptation.
Meaning of 'Detected,' 'Median,' and 'Range' in This Sampling Record
Detected
Means the testing instrument measured chromium-6 above 0.03 µg/L in 37 of 43 samples; this is a factual measurement, not a violation.
Median
Half of the detected samples measured below 0.14 µg/L and half above; the median shows typical levels found but not risks for individual homes.
Range
The lowest detection above reporting was 0.03 µg/L; the highest was 0.3 µg/L, showing variability in the water system's chromium-6 levels.
What the Measured Range Means Compared to Federal Standards—and What It Does Not Mean
Relation to Legal Limits
There is no federal maximum contaminant level (MCL) for chromium-6 specifically; total chromium MCL is 100 µg/L, far above measured chromium-6 levels here.
No Violation or Unsafe Condition Recorded
The detections do not represent violations or unsafe water according to EPA records for this public water system.
Sampling Scope and Individual Variability
These figures reflect system-wide monitoring, not any single home's water quality, which requires personal testing to determine.
Do not conclude from this area data alone that your home's water contains chromium-6 at these levels or requires treatment. Personal water testing is necessary to identify specific conditions. The C-Series Chromium-6 Filter offers a documented approach to reducing chromium-6 where needed, based on direct knowledge of water quality at the point of use.
Where this information comes from
Source: EPA SDWIS public water system record. Sampled 2014-12-16. These figures describe the public water system's record, not the plumbing inside any individual building.
On record: EPA UCMR3 monitoring (2013-2015) for Meriden Water Division (CT0800011), CT: 87 results across 2 listed contaminants, 50 detections above the reporting level; no federal MCL for hexavalent chromium; total chromium MCL 100 ug/L
