If Concord’s Water Record Reflects Zero 90th Percentile Lead, What Does That Mean for Your Home Compared to Nearby Counties?

The City of Concord’s public water system supplies over 120,000 people in Cabarrus County through tens of thousands of connections. Official EPA sampling for lead in distribution plumbing sampled in 2025 found a 90th percentile level of 0 mg/L. This measure means that 90% of tested taps showed concentrations at or below zero, effectively no detectable lead was found in those samples. It does not represent lead levels in your specific household's water, nor does it reflect private wells or premise plumbing conditions not captured by the system's routine testing.

Nearby counties may have differing sampling records, sometimes showing low-level detections or other patterns. Comparing these records should be done cautiously: a detection in one area is not proof of a problem in your home, and Concord’s zero 90th percentile finding does not guarantee all homes have identical water quality. Regional trends help frame expected lead risks but cannot substitute for your own water's analysis.

If Your Household Plumbing Is Older or Contains Lead Components, How Does This Affect Your Lead Risk Separate from the Public Water Source?

Lead presence in household water often relates more to the plumbing materials and age of your home’s pipes and fixtures than to the water source itself. Even with a public system showing no detectable lead in distributed water, lead can enter water through contact with lead solder, brass fixtures, or lead pipes inside a building.

Because Concord’s water supply comes from surface water sources treated before distribution, the source water is less likely to contain lead. However, household plumbing can leach lead under certain conditions like water corrosivity and stagnation. The age of your plumbing and the presence of lead components strongly influence your water’s lead content at the tap.

If EPA Sampling Notes Terms Like 'Detected,' 'Median,' and 'Range,' What Do They Indicate About Lead Levels in Concord’s Water System?

The EPA’s published sampling results include statistical measures designed to summarize lead in water samples across many taps. 'Detected' means laboratory instruments measured lead at a certain level in some samples. A 'median' shows the middle value in the set of results, and the 'range' indicates the lowest to highest measurements found.

In Concord’s 2025 sampling, the 90th percentile lead level was zero, signaling no detection above zero in the majority of tested taps. This does not equate to a safety guarantee or confirm every tap’s lead level is zero. It simply means lead is below quantifiable levels in the distribution system during that sampling event. Individual home tests may differ.

If You Consider Using a Treatment System Like the Pentair Lead in Water Filter, How Does It Address Lead Specifically?

The Pentair Lead in Water Filter operates with technology designed to reduce lead content at the point of use. It captures and removes lead particulates and dissolved lead ions present in your household water. This filtration can provide an additional safeguard especially in homes where plumbing materials may contribute to lead presence.

This system ships ready to configure for your water line and does not require additional equipment. Using a dedicated lead filter is an effective way to ensure water you consume or prepare food with has reduced lead concentration regardless of the municipal supply or plumbing conditions.

If Your Water Source Type, Sampling Depth, or Well Depth Varies, How Should You Adjust Expectations About Lead Presence?

Concord’s supply relies on surface water rather than groundwater, which usually contains different mineral content and lead mobilization dynamics. Sampling depth matters: EPA’s lead testing focuses on tap water after stagnation periods to capture lead leached from plumbing, not from the source itself.

Private wells in Cabarrus County may have different lead profiles, influenced by well depth, casing materials, and local geology. If your water comes from a private well, Concord’s public water system record does not apply directly. You should obtain specific laboratory testing for your well water to assess lead levels.

What is the Definitive Test You Should Conduct to Know Your Household Lead Levels?

To determine if your home’s water contains lead at any level, a certified laboratory test on a first-draw tap water sample is essential. This test captures lead dissolved or suspended in water after sitting in household plumbing for several hours. Only this direct measurement shows whether lead is present in your tap water and at what concentration.

Once you have your water tested, you can decide if a targeted solution like the Pentair Lead in Water Filter is appropriate to reduce lead exposure effectively and reliably.
