Quick Answer
Is lead in drinking water a real concern in Arkansas?
Yes — Little Rock, Fort Smith, Fayetteville, and other Arkansas cities have significant pre-1986 housing stock where lead solder and older service connections may be present.
Is this mostly a public-water issue, a private-well issue, or both?
Primarily public water service lines and household plumbing in older urban areas; older neighborhoods in Little Rock and Fort Smith have the highest concentration of aging water infrastructure.
What is the main reason residents should care?
Arkansas's major cities grew significantly before the 1986 federal ban on lead solder and materials. Little Rock's historic neighborhoods and Fort Smith's older core have a high density of pre-1986 construction. Some Arkansas water sources are naturally soft, increasing the corrosivity of water toward older lead-bearing plumbing.

Why This Matters in Arkansas
Arkansas has more than 700 public water systems regulated by the Arkansas Department of Health. Little Rock, Fort Smith, Jonesboro, and Fayetteville all have urban neighborhoods built before the 1986 federal ban on lead solder, making lead at the tap a plausible concern in homes with original plumbing. Ozark Mountain communities in northwestern Arkansas draw from naturally soft, low-mineral groundwater sources, which can be more corrosive toward lead plumbing materials than harder water supplies. ADH enforces the Lead and Copper Rule and requires public water systems to complete service line inventories under the federal LCRR.
Arkansas Utilities With Lead Violation Records
The utilities listed below have at least one lead violation on record in EPA's SDWIS database. Violations may be open or resolved — see individual utility pages for current status and risk level.
How Lead Gets Into Drinking Water
Lead service lines
The pipe connecting a home to the water main may be made of lead, especially in pre-1986 construction. Water sitting in these lines can accumulate lead before it reaches the tap.
Lead solder
Lead solder at pipe joints was banned for potable water systems in 1986. Homes built before that date — including significant portions of older Arkansas cities — may still have lead solder throughout their plumbing.
Older brass fixtures
Faucets, valves, and fixtures with high lead content were common before the 2014 revision of 'lead-free' standards. Replacing older fixtures at kitchen and drinking taps can meaningfully reduce exposure.
Corrosive water chemistry
Soft, acidic, or low-alkalinity water dissolves lead from plumbing more readily. Utilities use orthophosphate and other corrosion control treatments, but household plumbing after the meter is not within their control.
Who Should Pay Closest Attention
Households with children under six in older Little Rock and Fort Smith neighborhoods, renters in pre-1978 rental housing, and families in older Arkansas communities who have not tested their tap water should consider certified filtration as a precautionary measure.
Families with children under six
Pregnant residents
Households in homes built before 1986
Renters who cannot inspect building plumbing
Residents on a confirmed lead service line
Households that had plumbing work done recently (disturbances dislodge protective scale)
How to Check Your Situation in Arkansas
- 1
Identify your water utility. Use the ZIP lookup below or browse the Arkansas utility directory on this site.
- 2
Read your utility's page on this site to see its current risk level and any open lead violations.
- 3
Contact your utility and ask for your address-level service line material status. Under the federal Lead and Copper Rule Revisions (LCRR), utilities must maintain and provide this information.
- 4
Review your utility's most recent Consumer Confidence Report (CCR) — mailed annually or available on the utility's website.
- 5
Consider testing your tap water at a Arkansas Department of Health (ADH)-certified lab. Your state health department or Arkansas Department of Health (ADH) maintains a list of certified labs.
- 6
If you have young children or are pregnant, install a certified NSF/ANSI 53 or 58 filter at the kitchen tap as a precautionary measure.
Treatment Options
Boiling does not remove lead. Use a certified filter for drinking and cooking water.
NSF/ANSI Standard 53 — Activated Carbon Block
Under-sink or pitcher filters certified to Standard 53 are independently verified to reduce lead. Replace filters on the manufacturer's schedule — an overdue filter may not perform as certified.
NSF/ANSI Standard 58 — Reverse Osmosis
RO systems certified to Standard 58 remove 95–99% of lead and a broad range of contaminants. Requires under-sink installation. More comprehensive than Standard 53 for households with multiple contaminant concerns.
Flushing — temporary mitigation only
EPA recommends flushing the cold tap for 30 seconds to 2 minutes if water has sat in pipes for 6+ hours. Not a substitute for certified filtration or service line replacement.
