Quick Answer
Is lead in drinking water a real concern in Nevada?
Moderate — Las Vegas and Henderson are relatively newer cities with less legacy lead infrastructure than older eastern cities, but Reno and Carson City have older neighborhoods with pre-1986 plumbing.
Is this mostly a public-water issue, a private-well issue, or both?
Primarily older household plumbing and fixtures in pre-1986 homes; lead service lines are less prevalent in Nevada's newer development areas but present in older Reno and Carson City neighborhoods.
What is the main reason residents should care?
Nevada's rapid post-WWII growth means much of Las Vegas and suburban Clark County was built after the 1986 lead ban, reducing the lead service line risk compared to older eastern states. However, older Reno and Carson City neighborhoods and pre-1986 homes throughout the state still have lead solder and older fixtures as a concern.
Key Facts
| Federal Lead Action Level | 15 µg/L — no safe level per CDC |
| Las Vegas context | Predominantly post-WWII construction — lower LSL risk than older eastern cities |
| Reno and Carson City risk | Older pre-1986 neighborhoods with lead solder and older fixtures |
| Hard water note | Nevada's Colorado River and groundwater sources are hard — somewhat protective against corrosion |
| State oversight | Nevada Division of Environmental Protection (NDEP) |
Why This Matters in Nevada
Las Vegas is predominantly a post-1960 city, meaning most of its residential and commercial infrastructure was built after lead service lines became rare and after lead solder was widely reduced. However, older neighborhoods in North Las Vegas and downtown Las Vegas, as well as pre-1986 homes throughout Clark County, still have lead solder and older brass fixtures. Reno and Carson City, Nevada's older cities, have concentrations of mid-century housing where lead solder was standard. Nevada's water tends to be hard (drawn from Lake Mead and other Colorado River sources in southern Nevada, and from hard groundwater in northern Nevada), which provides some natural protection. NDEP oversees drinking water quality statewide.

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 Nevada 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
Families with young children in older Reno and Carson City neighborhoods and in any pre-1986 Nevada home should consider flushing taps before use and installing a certified NSF/ANSI 53 filter at the kitchen tap. Even in Nevada's newer cities, older fixtures and appliances may contain lead.
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 Nevada
- 1
Identify your water utility. Use the ZIP lookup below or browse the Nevada 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 Nevada Division of Environmental Protection (NDEP)-certified lab. Your state health department or Nevada Division of Environmental Protection (NDEP) 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.
