LCRI Service Line Verification: Lessons from the Field

Lead & Copper Rule

Policy

LSL Inventory

Compliance webinars can get theoretical pretty fast, but this one didn't.

Our February session paired regulatory context with a genuinely practical playbook for verifying unknown service lines, backed by a technical assistance program that has already identified over 20,000 service lines across three states and a field contractor with thousands of inspections under his belt.

Here's what stood out.

A quick regulatory refresher

The Lead and Copper Rule Improvements (LCRI) status has not changed since our last recap: 

  • The Environmental Protection Agency (EPA) has finalized the rule. 
  • The American Water Works Association (AWWA) is still challenging it in court.
  • The EPA still plans to defend the rule as written.

The advice is the same too: Prepare for LCRI compliance as if the rule holds since the baseline service line inventory deadline, November 1, 2027, is approaching fast.

One update worth flagging: five states (Illinois, Michigan, Pennsylvania, New Jersey, and New York) currently treat connector material as something that does affect service line classification, unlike most states where it doesn't. If you're in one of those states, it's worth checking.

Verification is a project, not a task.

The bulk of the session made a simple but important point: Treating lead service line verification like a single to-do item is exactly how it goes sideways.

One utility's do-it-yourself attempt got through 30 addresses in two weeks, with data scribbled on paper that was barely legible by the time it made it back to the office. Not exactly audit-ready.

The alternative is to treat it like any other capital project, broken into three phases:

  1. What you know before you start
  2. The actual fieldwork
  3. What happens with the data afterward

Most of the payoff comes from phase one. The more due diligence done up front – records review, customer surveys, tracking down materials already documented from unrelated projects like meter change-outs – the fewer expensive digs are needed later.

Statistical analysis and predictive modeling both showed up again here as ways to shrink that inspection pool, with a rule of thumb for choosing between them:

  • Statistical analysis works well when a system has no known lead service lines or galvanized requiring replacement (GRR).
  • Predictive modeling picks up once some lead service lines or GRR have already been found.

Choosing verification tools and contractors

A geographic information system (GIS) came up as the recommended way to manage field data, both for its accessibility to field crews and its ability to feed a dedicated water data platform for reporting and dashboards. A live example showed how a simple red-to-green dot system can track inspection progress across an entire project.

Contractor selection got real talk too. The advice: look past the local guy who fixes leaks and installs service lines, and vet specifically for experience with this kind of verification work, GIS compatibility, and a willingness to work without constant utility oversight.

A signed statement of work covering responsibilities, deliverables, pricing, and timeline was called out as a must, not a nice-to-have, so expectations stay aligned from the start.

What verification actually looks like in the field

The session's field contractor walked through what a typical inspection day looks like, from routing crews (harder than it sounds in an unfamiliar system) to reading the room during kickoff meetings (staff who know their system inside and out make everything run more smoothly).

GPS points and photo documentation from every inspection were highlighted as the backbone of defensible data, which matters if records ever face regulatory scrutiny.

Customer communication came up as its own art form. Timing mailers and social posts too early means people forget; too late means confused customers calling the police on a crew standing near their meter box. A few real examples of both extremes made the case for planning your LCRI communications strategy early.

Watch the Full Session

We discussed many more important verification topics, including:

Funding options, inspection method tradeoffs (meter pit versus potholing versus hydrovac), documentation strategies, and a full Q&A covering everything from access agreements to lead service line replacement plans when a homeowner owns the entire service line.
