Is There Cadmium in Hartford, CT Water? (ZIP 06140)
By Alexander Snyder, Founder & Water Quality Data LeadLast reviewed August 2026
Cadmium appears in the preserved historical public-system catalog associated with Hartford, CT ZIP 06140. The old percentage and comparator fields are not republished by this route recovery, and the ZIP association does not identify a property's serving utility or measure its tap.
Federal legal limits and other governed references answer different questions. Neither establishes exposure, safety, or health risk at a specific property.
What Is Cadmium?
Cadmium is a toxic metal found in food and drinking water. Health evidence reviewed by EWG includes kidney toxicity, bone damage, cancer, and effects on developing fetuses.
This is exact-analyte context. It does not establish that cadmium is present at a property or that a ZIP-associated record represents exposure.
Who May Need Closer Review?
The governed EWG release identifies these household groups for closer cadmium review. The classification does not lower or multiply the cited reference and does not determine anyone's exposure.
Confirm the serving utility and use a certified property sample before making a health, exposure, or treatment decision.
How to Reduce Cadmium at a Property
The reviewed certification sources include an exact Cadmium reduction claim under NSF/ANSI 58. Certification is product- and claim-specific; the standard number alone does not prove a product reduces cadmium.
- 1Confirm the analyte and concentration at the relevant tap or well with a certified laboratory before choosing treatment; a ZIP-associated record is not a property result.
- 2Choose a specific current product whose independent certification listing and performance data sheet explicitly name the exact reduction claim. A standard number by itself is not an analyte claim.
- 3Follow the certified product's inlet conditions, installation, service-life, and replacement instructions, then retest treated water to verify performance at the property.
Certification verifies a named reduction claim under defined test conditions; it does not certify that every installation reaches CheckYourTap's EWG/OEHHA health reference.

This page can explain the general science about ZIP-associated Cadmium records, but it cannot identify what is at a specific tap or property. You can get ZIP-level context two ways:
- Inside the chat: ask your assistant to “check my tap water with CheckYourTap”. Our connector returns available public-system or regional monitoring records associated with your ZIP. It does not identify your serving utility or test your tap, well, or property. The current connector is read-only and does not email reports or submit contact information.
