## Short answer

A lead service line notice is the letter a water system must send to every address its
inventory records as lead, galvanized requiring replacement (GRR) or lead status unknown,
and must repeat annually until the line is reclassified as non-lead. EPA Region 8's
deadline deck puts the initial notice at 15 November 2024 and every repeat inside the
calendar year, by 31 December. Maine's Drinking Water Program says the 2026 notices go out
by 31 December 2026 and the system certifies delivery to the state by 1 July 2027. The
category is the whole message. Under EPA fact sheet EPA 816-F-24-019, lead status unknown
means only that the material has not been demonstrated, so the line is neither cleared nor
confirmed. If you think the category is wrong, say so in writing: 40 CFR 141.84 then gives
the system 30 days to respond with an offer to inspect the line.

## Fact sheet

- **Answer:** Water systems must notify every address whose service line is categorised lead, galvanized requiring replacement or lead status unknown, and repeat that notice annually until the line is reclassified. EPA Region 8 puts the repeat inside each calendar year, by 31 December. Under 40 CFR 141.84, telling the system its categorisation is wrong obliges it to respond within 30 days with an offer to inspect the line.
- **Basis:** The notification duty in 40 CFR 141.85(e), the categorisation-dispute duty in 40 CFR 141.84, and the service line definitions in EPA fact sheet EPA 816-F-24-019 (October 2024).
- **Assumptions:** Community or non-transient non-community public water system; a private well has no inventory row and receives no notice.; The notice concerns the service line between the water main and the building, not the pipework inside it.; Deadline dates are the pre-compliance schedule; the LCRI compliance date of 1 November 2027 moves the annual notice date.
- **Method:** Deadlines read from EPA Region 8's lead service line inventory deck of 21 November 2025 and Maine Drinking Water Program's LCRR/LCRI Field Guide; rule text read from 40 CFR 141.84 and 141.85; definitions from EPA 816-F-24-019.

If what you actually want is the scratch-and-magnet test and the filter class that reduces lead, this is the wrong page: that is [how to tell if you have a lead service line](/water/guides/lead-in-tap-water-service-line/), and this one stops at the letter.

## What do the three categories on the letter mean?

Two of them describe a pipe. The third describes a missing record.

| Category on the letter | EPA 816-F-24-019 definition | What it does not mean |
|---|---|---|
| Lead | A service line made of lead | Nothing about the pipework inside the building, which the notice does not cover |
| Galvanized requiring replacement (GRR) | A galvanized service line that currently is or ever was downstream of a lead service line, or is currently downstream of a lead status unknown service line | Not a judgement about the galvanized steel itself: it is about what sat upstream of it |
| Lead status unknown | A service line whose pipe material has not been demonstrated to be lead, GRR or non-lead | Not "probably fine", and not "probably lead". It is an unproven row |

The fourth category, non-lead, is the only one that ends the letters, and EPA 816-F-24-019
reaches it only through an evidence-based record, method or technique.

## Why is one neighbour's letter longer than another's?

Because the rule writes two notices with different contents.

40 CFR 141.85(e)(3)(i) sets eight required items for a lead or GRR notice, among them a
statement that the consumer can request tap water sampling, a statement that the system must
replace its portion when the owner replaces theirs, and instructions for telling the system
you disagree with the categorisation. 141.85(e)(3)(ii) gives the unknown notice a shorter
list, plus information about opportunities to verify the material of the line.

## What does the water system owe next, and by when?

The dates below are the schedule in force before the Lead and Copper Rule Improvements
compliance date. They move after it.

| Date | What happens | Source |
|---|---|---|
| By 31 December each year | Annual notice delivered, unless every service line is non-lead | EPA Region 8; Maine DWP |
| 1 July following | The system certifies to the primacy agency that it delivered last year's notices | Maine DWP |
| 1 November 2027 | LCRI compliance date: baseline inventory due, lead action level moves from 15 ppb to 10 ppb | Maine DWP |
| 1 December 2027, then 1 March 2029 | The annual notice date itself shifts | Maine DWP |

Maine's field guide is a state primacy agency document, so confirm your own state's dates
with its drinking water programme.

## What does a tenant do that an owner cannot?

A tenant is entitled to the letter and to act on it. 40 CFR 141.85(e)(1) requires
notification to customers and all persons served at that service connection, not only to the
account holder.

Consent to replace the line is the owner's. EPA 816-F-24-019 requires the system to make a
reasonable effort to obtain it, defined as at least four attempts using at least two
different communication methods, and to offer full replacement to a new owner within six
months of a change in ownership. Refusal does not stop the annual notices.

**Before you buy anything**

Do not buy a filter off the back of this letter. The letter tells you a category, not a number, and 40 CFR 141.85(c) already entitles you to ask the system for a tap sample at a site on a lead, GRR or unknown line. Those samples must capture both premise plumbing and service line water (first- and fifth-litre), and the result must reach you no later than three business days after the system learns it. Get the number first, then read [which filter class is certified to reduce lead](/water/guides/lead-in-tap-water-service-line/).

## How do you answer the letter?

1. Find your address in the inventory. EPA 816-F-24-019 requires the inventory to be publicly accessible, and systems serving more than 50,000 people to post it online. Your annual water quality report carries the access instructions: see [how to read your Consumer Confidence Report](/water/guides/how-to-read-your-consumer-confidence-report/).
2. If the category looks wrong, write to the system naming your service address. That starts the 30-day clock in 40 CFR 141.84 for an offer to inspect.
3. Request the tap sample in the same letter, and keep the dated copy.
4. Ask what the system's replacement programme covers on the customer side.
5. Keep each year's notice. The date it stops arriving is the date your line was reclassified.

## Who pays for the replacement?

Ask before assuming the customer-side pipe is yours to fund. EPA's federal funding page
states that the Infrastructure Investment and Jobs Act invests $15 billion towards lead
service line replacement through the Drinking Water State Revolving Fund, that 49% of those
funds go to communities as grants or principal forgiveness loans, and that the entire service
line from the water main to the point where it meets premise plumbing is eligible.

One more thing worth asking for: EPA 816-F-24-019 requires the system, after a full or
partial replacement, to provide a pitcher filter or point-of-use device certified by an
ANSI-accredited certifier to reduce lead, six months of replacement cartridges, flushing
instructions, and an offer to collect a follow-up tap sample three to six months later.

## Frequently asked questions

### Does an unknown service line mean my water has lead in it?

No, and it does not mean the opposite either. EPA fact sheet EPA 816-F-24-019 defines a lead status unknown service line as one whose pipe material has not been demonstrated to be lead, galvanized requiring replacement or non-lead. It is a record-keeping category. Only an inspection or an evidence-based record moves the line into one of the other three.

### I rent. Why did I get this letter instead of my landlord?

Because 40 CFR 141.85(e)(1) requires the notice to reach customers and all persons served by the water system at that service connection, not only the account holder. A tenant can request the tap sample and can dispute the categorisation. Consent to dig up and replace the line, however, is the property owner's decision, not the tenant's.

### What happens if I tell the utility the category on my letter is wrong?

40 CFR 141.84 gives the system 30 days from receiving your notification to respond with an offer to inspect the service line. Put the dispute in writing, name your service address and say what you observed. An inspection is the fastest route out of the unknown category, because unknown lines are cleared only by evidence.

### Why is my neighbour's letter longer than mine?

The rule writes two different notices. 40 CFR 141.85(e)(3)(i) gives a lead or galvanized-requiring-replacement notice eight required items, including replacement financing and instructions for disputing the categorisation. 141.85(e)(3)(ii) gives the unknown notice a shorter list plus information about opportunities to verify the material. A shorter letter is a category difference, not a lesser risk.

### Will the letters stop if I refuse to let the crew replace the line?

No. EPA 816-F-24-019 states the water system must continue annual notification of service lines known or potentially containing lead regardless of whether access is obtained after a reasonable effort. That reasonable effort is defined as at least four attempts to engage the property owner using at least two different communication methods.
