No safe level of lead exists for children. The CDC and EPA have established that there is no known safe blood lead level in children. Even small amounts can affect brain development, IQ, and behavior. Lead in drinking water is invisible, tasteless, and odorless. The only way to know if it is present is to test. If your home was built before 1986 and has children under 6, test now.
The Issue: Two Different Lead Problems
When people ask whether their water is safe, they often check their utility’s Consumer Confidence Report and see that the utility has no lead violations. That report reflects the water leaving the treatment plant and the utility’s distribution system. It does not measure what happens inside your home.
There are two distinct lead exposure pathways in Middle Tennessee homes, and they require different responses:
Pathway 1 — Higher risk
Lead service lines and galvanized pipes
The pipe connecting the water main in the street to your home. Lead service lines were common before the mid-1950s in Nashville, before 1979 on privately owned lines. When water sits in a lead service line overnight, lead dissolves directly into the water. Flushing for 3–5 minutes before drinking reduces but does not eliminate this risk.
Relevant for: Pre-1955 Nashville homes, pre-1979 Nashville private lines, older homes in Franklin, Murfreesboro, Clarksville historic districts
Pathway 2 — Moderate risk
Lead solder at copper pipe joints
From 1950 through 1986 (federal ban) and 1988 (Tennessee ban), the standard method for joining copper pipes was 50/50 lead-tin solder. Homes with copper pipes and lead solder present ongoing risk, particularly when acidic or corrosive water contacts the joints. The amount of lead leached increases when water sits in the pipes for several hours.
Relevant for: Any Middle Tennessee home built 1950–1988 with copper plumbing. This includes most 1960s, 1970s, and early 1980s construction throughout Davidson, Williamson, and Rutherford Counties
Pathway 3 — Moderate risk
Brass faucets, fixtures, and valves
Until 2014, “lead-free” brass fixtures could legally contain up to 8% lead by weight. Faucets, shutoff valves, pressure regulators, and fittings installed before January 4, 2014, may leach lead at the point of use. Kitchen and bathroom faucets are the primary exposure points. Running water briefly before use does not fully clear lead from brass components.
Relevant for: Any pre-2014 faucet or fixture in Middle Tennessee. Very common in kitchen faucets replaced before 2014 even in newer homes
Pathway 4 — Lower risk (Nashville)
Distribution system — utility pipes
Nashville MWS, La Vergne, Smyrna, and most major Middle Tennessee utilities have conducted Lead Service Line Inventories and report no significant lead in their distribution systems. Nashville MWS adds a food-grade phosphate solution that bonds to pipe walls to prevent corrosion. CUD Rutherford (Murfreesboro) and La Vergne WS have completed LSLI with zero lead service lines confirmed.
Nashville MWS stopped using lead on the utility side in 1975. The phosphate corrosion control program significantly reduces leaching risk from the distribution system
The Nashville Lead Timeline
Nashville has a more specific timeline than the national standard. Understanding it helps you assess risk based on your home’s construction date.
pre
1955
1955
Before 1955
Highest risk — lead service lines may be present on both sides
Lead was the standard material for service lines connecting homes to the water main. Nashville homes built before 1955 have the highest probability of having a lead service line, either on the utility side, the private property side, or both. Lead service lines are the most significant source of lead in drinking water nationally.
Nashville neighborhoods with high pre-1955 housing stock: Germantown, Edgefield, East Nashville (historic), Sylvan Park, West End, 12South (older sections)
1955
1955
Nashville MWS stops installing lead on utility-owned service lines
Nashville Metro Water Services stopped using lead for the utility’s portion of the service line (from the water main to the meter). Homes built after 1955 are less likely to have utility-side lead service lines, but the private-side line (from meter to house) may still be lead for another 24 years.
1979
1979
Nashville MWS stops allowing lead on private-side service lines
Nashville banned lead from the private property side of service lines (from meter to home). Homes built after 1979 in Nashville proper are unlikely to have lead service lines. However, copper pipes with lead solder remain the standard until the federal ban in 1986.
1986
1986
Federal Safe Drinking Water Act amendment bans lead solder nationally
The 1986 amendment to the Safe Drinking Water Act banned the use of lead solder containing more than 0.2% lead and lead pipes in new or repaired plumbing. This applies nationally. Homes built in 1986 or later should not have lead solder in new construction — though renovation work using old materials may have introduced lead solder after this date.
The 1985–1988 window is a particularly uncertain zone: construction may have begun before the ban but been completed after, or vice versa. If your home was built between 1984 and 1990, testing is the only reliable way to know
1988
July 1988
Tennessee state lead ban takes effect
Tennessee enacted its own lead ban for service lines effective July 1988 — two years after the federal ban. Homes built after July 1988 in Tennessee are subject to the state ban and should not have lead materials in new service lines. This two-year gap between the federal and state bans means some 1986–1988 Tennessee construction may have used lead materials legally under state law.
2014
January 4, 2014
True lead-free fixtures required — 0.25% maximum lead by weighted average
The Reduction of Lead in Drinking Water Act took effect, reducing the legal lead content in plumbing fixtures from 8% to a weighted average of 0.25%. Faucets, valves, and fittings sold and installed after this date must meet the new standard. Any faucet or fixture installed before January 4, 2014, may contain up to 8% lead by weight.
Brass faucets in Middle Tennessee homes installed before 2014 are a common overlooked lead source. Even in a post-1986 home with no lead solder, a pre-2014 kitchen faucet may be leaching lead at the point of use
2037
2037
Nashville MWS compliance deadline for Lead Service Line replacement
Under EPA’s Lead and Copper Rule Improvements (LCRI), all utilities must replace lead service lines within 10 years of the rule taking effect. Nashville MWS is currently conducting its Lead Service Line Inventory (LSLI) and will develop a replacement plan meeting the 2037 deadline. Nashville currently replaces lead lines as they are found during construction and repair activities.
How to Identify Lead Plumbing in Your Home
You can do a preliminary visual assessment of your home’s plumbing before arranging a water test. These are the materials to look for and how to distinguish them.
LEAD
Lead service line
Grey color, dull finish. Soft enough to scratch with a key or coin — scratch the surface and look for bright silver metal beneath the dull exterior. Swings slightly when tapped (lead is flexible). No magnetic attraction to a magnet. Found where the water supply pipe enters the foundation or basement.
GAL
VANIZED
VANIZED
Galvanized steel pipe
Silver-grey, rough texture. Magnetic (a magnet sticks). Often with visible rust or orange-brown discoloration. Common in pre-1960s homes. May have been installed downstream of a lead service line, meaning it has accumulated lead particles inside even though it is not itself lead. Required for replacement under new EPA rules if it was ever downstream of lead.
COPPER
+SOLDER
+SOLDER
Copper pipe with lead solder
Orange-brown copper pipe with silver-grey blobs at each joint connection. Lead solder looks dull and slightly lumpy at joints; modern lead-free solder is shinier and smoother. Common in homes built 1950–1988. The solder itself is the risk — the copper pipe is safe. Look for the joint appearance, not the pipe color.
COPPER
NO LEAD
NO LEAD
Copper pipe with lead-free solder (post-1986)
Same orange-brown copper but with shinier, smoother joints. Post-1986 lead-free solder typically uses tin-antimony or tin-silver alloys. Hard to distinguish visually from lead solder — if construction date is uncertain, test the water rather than relying on visual inspection alone.
PVC /
PEX
PEX
PVC or PEX plastic pipe
White (PVC) or flexible red/blue tubing (PEX). No lead leaching risk from the pipe itself. Common in homes built after 1990 and in renovated plumbing. Even with plastic pipe, an older brass fixture or a lead service line at the street connection can still introduce lead. Always check the fixture and service line separately.
BRASS
FIXTURE
FIXTURE
Brass faucets and fixtures (pre-2014)
Gold or yellow-brown metal. Check the fixture date code stamped on the cartridge or valve body. Any faucet installed before January 4, 2014, may contain up to 8% lead. Kitchen faucets are the primary concern because they supply drinking and cooking water. Bathroom faucets are lower priority unless used for drinking.
Nashville MWS tip
Nashville uses XRF devices to identify service line material — you can request an assessment.
Nashville MWS is using handheld X-ray fluorescence (XRF) analyzers to identify service line materials as part of their LSLI process. These devices give an accurate material reading in approximately one second. Contact Nashville Metro Water Services through their LSLI portal (bit.ly/MWSPIPE) to request a service line material assessment for your property. This is the most accurate non-destructive method for identifying whether your service line is lead.
Risk by Neighborhood and City
Lead plumbing risk in Middle Tennessee is not evenly distributed. It concentrates in neighborhoods with significant pre-1955 housing stock (service line risk), widespread 1960s–1980s construction (lead solder risk), and areas where pre-2014 renovation is common (fixture risk). These are the areas where testing is most warranted.
Nashville
Germantown & Salemtown
High service line risk
Pre-1900 to 1930s housing stock. High probability of lead service lines predating Nashville’s 1955 ban. Test first-draw water and request LSLI assessment.
Nashville
East Nashville (historic core)
High service line risk
Victorian and Craftsman-era homes. Many pre-1920 structures. High lead service line probability. Renovation boom means older lead plumbing is frequently disturbed, which can increase short-term lead release.
Nashville
Sylvan Park & West End
High service line risk
1920s–1940s construction. Lead service lines possible on private side even after 1955. Copper with lead solder present in 1950s–1960s additions and renovations.
Nashville
Green Hills & Belle Meade
Moderate solder risk
1940s–1970s construction dominant. Lead service lines less likely (post-1955 utility side) but copper with lead solder very common in original and renovated plumbing. Expensive homes often have older plumbing that has never been updated.
Nashville
12South & Melrose
Moderate solder risk
1940s–1980s housing. Renovation-heavy market. Lead solder risk from original copper plumbing and from pre-2014 fixture installations during frequent renovations. Test especially if recently renovated with older materials.
Franklin
Historic downtown Franklin
Moderate solder & service line risk
Pre-1940 structures along Main Street corridor. Franklin WD has moderate corrosion potential from Harpeth River source water, which can increase lead leaching from solder joints. Test any pre-1970 home in Franklin.
Murfreesboro
Historic downtown & College Area
Moderate solder risk
Pre-1960 housing around MTSU campus and historic square. Lead solder risk. MWRD has completed LSLI with no lead service lines in distribution system, reducing pathway 1 risk, but home plumbing solder remains a concern in older structures.
Murfreesboro / Smyrna
Post-1990 subdivisions
Lower risk
Post-1990 construction predominantly uses copper with lead-free solder or PEX tubing. Primary risk is brass fixtures installed before 2014. Both MWRD and Smyrna WS confirmed no lead service lines in their LSLI results.
La Vergne / Smyrna
All areas
Lower risk (utility side)
La Vergne WS confirmed zero lead service lines in its LSLI (2025). Smyrna WS also reports zero lead in distribution. Pre-1986 home plumbing solder remains a risk for individual homes but utility-side risk is lowest in this area of Middle Tennessee.
How to Test Your Water for Lead
Visual inspection can suggest risk but cannot confirm lead in your water. A certified laboratory test is the only reliable method. The sampling protocol matters as much as the lab itself.
1
Use the first-draw sampling protocol
The highest-risk sample is the very first water from your kitchen tap after it has sat idle for at least 6 hours — typically first thing in the morning before anyone has used any water. This maximizes contact time between water and any lead materials in the household plumbing. Do not pre-flush. Collect the first 250ml from the kitchen tap into the lab-provided bottle.
2
Also collect a second-draw sample
After collecting the first-draw sample, immediately collect a second 250ml sample. The second draw reflects lead from the pipe within the home rather than from the fixture itself. Comparing first and second draw results helps identify whether lead is coming from the faucet/fixture (first draw higher) or from the service line or household pipes (second draw higher).
3
Request a TDEC-certified laboratory
Use only a Tennessee Department of Environment and Conservation (TDEC) certified laboratory for results that are legally defensible and appropriate for health decision-making. Certified labs: National Testing Laboratories (nationwide, mail-in), A&B Labs (Nashville area), and UT Soil, Plant and Pest Center (Knoxville, accepts statewide samples). Cost: approximately $20–$40 for a lead test.
4
Nashville MWS customers: request a free test kit
Nashville Metro Water Services offers free lead testing kits for Nashville city water customers. Contact MWS directly through their Lead Service Line Inventory portal at bit.ly/MWSPIPE. The kit includes sampling bottles, instructions, and lab processing. This is the most cost-effective option for Nashville customers and the results feed directly into Nashville MWS’s LSLI data.
5
Interpret your results correctly
EPA action level: 15 ppb. No level is considered safe for children. If any lead is detected above 0 ppb in a household with children under 6 or pregnant women, install an NSF/ANSI 53 certified filter immediately — do not wait until the level reaches the action level. A result of “not detected” means lead was below the lab’s detection threshold (typically 1–5 ppb) — not necessarily zero.

Filters That Actually Remove Lead
Not all filters remove lead. The type of carbon, the certification, and most critically whether lead is specifically listed in the NSF/ANSI certification documentation all matter. Here is what works and what does not.
Standard whole-house carbon backwashing filters do NOT remove lead. The granular activated carbon (GAC) used in whole-house backwashing systems is not effective for lead removal. Do not assume a whole-house filter is protecting your family from lead. Lead requires a specific point-of-use solution at the kitchen tap.
1
Under-sink solid block carbon filter (NSF/ANSI 53, lead listed)
Most effective and affordable lead removal at point of use. Carbon block — not granular GAC — is required.
NSF/ANSI 53
Solid block carbon cartridge filters (under-sink) with NSF/ANSI 53 certification specifically listing lead in the contaminant reduction claims remove lead at 97–99% efficiency at rated flow. The key is the word “solid block” — granular activated carbon (GAC) cartridges are much less effective for lead. Cost: $150–$500 for the filter system plus $30–$80/year for cartridge replacement. Always verify that “lead” appears in the specific contaminant list in the NSF 53 documentation — not just that the filter carries the NSF 53 certification number. Look up the specific model on the NSF Certified Products database at info.nsf.org.
2
Reverse osmosis system (NSF/ANSI 58)
Most comprehensive. Removes lead plus PFAS, chromium-6, nitrate, and all dissolved contaminants.
NSF/ANSI 58
An under-sink RO system removes 95–99% of dissolved lead through membrane rejection, plus addresses all other contaminants simultaneously. The preferred solution for households with multiple water quality concerns (lead from old plumbing, PFAS, TTHMs) because it solves all of them with one system. The pre-filter in an RO system typically includes an NSF 53 carbon block stage specifically for lead. Installed cost: $600–$2,000. ~4 cents per gallon.
3
NSF/ANSI 53 certified pitcher filter (Brita Longlast, ZeroWater, etc.)
Lowest cost entry point. Adequate for drinking and cooking water if used consistently. Not convenient for cooking volumes.
NSF/ANSI 53
Pitcher filters with NSF/ANSI 53 certification for lead (not all pitchers carry this — verify on the box or at info.nsf.org) are a low-cost option for drinking water only. The Brita Longlast+ filter is NSF 53 certified for lead; the standard Brita filter is not. ZeroWater pitchers are also NSF 53 certified for lead. Inconvenient for cooking volumes but acceptable for drinking water if the family consistently uses filtered water for all consumption. Cost: $20–$50 filter system, $20–$40/year for replacements.
How to verify
Always look up your specific filter model on NSF’s certified products database before buying.
NSF International maintains a free searchable database of every certified product at info.nsf.org/Certified/dwtu/. Search your filter model number and look specifically for “lead” in the contaminant reduction list. A filter carrying the NSF 53 certification may only be certified for VOCs or cysts — not lead. The certification number alone does not tell you lead is covered. This 60-second check is the most important step before purchasing any lead removal filter.

Frequently Asked Questions
If your Nashville home was built before 1986, there is a meaningful risk of lead from plumbing materials — specifically lead solder at copper pipe joints if built 1950–1986, and possibly lead service lines if built before 1979 (when Nashville MWS stopped allowing lead on the private property side). Nashville MWS stopped installing lead on the utility’s service lines in 1975. Homes in historic Nashville neighborhoods (Germantown, East Nashville, Sylvan Park, West End) built before 1955 have the highest probability of lead service lines. The only reliable way to confirm is a water test using the first-draw protocol or an XRF assessment through Nashville MWS’s LSLI program.
Nashville Metro Water Services stopped installing lead on the utility’s portion of service lines in 1975. They stopped allowing lead on the private property side (between meter and home) in 1979. The federal Safe Drinking Water Act amendment banning lead solder in all new plumbing took effect in 1986. Tennessee’s own state lead ban for service lines took effect in July 1988 — two years after the federal ban. Homes built between 1986 and 1988 fall in a gap where the federal ban applied but the Tennessee state ban had not yet taken effect.
No. A utility’s CCR reflects the lead levels measured at utility tap test sites, which are selected to represent the highest-risk homes in the system. If your home was not one of the test sites, its specific lead level is not reported in the CCR. More importantly, lead in water comes primarily from the home’s own plumbing — the service line, pipe solder, and fixtures — not from the water the utility delivers. A utility can have zero lead violations while an individual home with pre-1986 plumbing experiences significant lead exposure. The CCR and your home’s water are different things.
Any brass faucet, valve, or fitting installed before January 4, 2014, may contain up to 8% lead by weight. Look for a date code stamped on the faucet body or cartridge — manufacturers often stamp the year of manufacture on the body. If no date is visible and the faucet has been in place since before 2014, assume it may contain lead. Kitchen faucets are the highest priority because they supply drinking and cooking water. Replacing a pre-2014 kitchen faucet with a current certified low-lead model is one of the most cost-effective lead reduction steps for Middle Tennessee homeowners in post-1986 homes.
No. Boiling water does not remove lead — in fact, it concentrates lead by evaporating water and leaving the dissolved lead behind. Never boil water as a lead removal strategy. Use a certified filter (NSF/ANSI 53 for lead, or NSF/ANSI 58 for RO) at the kitchen tap. Flushing cold water for 1–3 minutes before drawing drinking water can reduce lead by clearing the most recently contact water, but it does not eliminate the risk from ongoing contact with lead materials.
Tennessee’s Residential Property Disclosure Act (T.C.A. § 66-5-201 to 210) requires most sellers to disclose known environmental hazards including lead. Renters have the right to a livable home under Tennessee landlord-tenant law. If you are renting and concerned about lead, you have the right to request your landlord test the water and provide results. Nashville MWS’s free lead test kit is available for any Nashville water customer including renters. If lead is detected, an NSF/ANSI 53 certified pitcher filter or under-sink filter is an immediate low-cost solution you can install without landlord permission in most cases.
EPA’s lead action level is 15 ppb (parts per billion) measured in first-draw samples. If 10% or more of a utility’s test samples exceed 15 ppb, the utility must take action including corrosion control treatment and notification. For individual homeowners: if your first-draw water test exceeds 15 ppb, install an NSF/ANSI 53 certified filter immediately, flush 3–5 minutes before drawing any water for cooking or drinking until the filter is installed, and contact Nashville MWS or your utility to report the result and request a service line material assessment. If children in the home are under 6, contact your pediatrician about a blood lead test. The action level of 15 ppb is not a “safe” level — it is the regulatory threshold at which utilities must act. No level is considered safe for children.
Test before you buy any filter — know what you’re treating.
A $25 first-draw water test tells you whether you have a lead problem before you spend $500 on a filter. Submit any quote for a free independent review.
