My standing rule: test with a kit, not a kid. Blood-lead screening tells you a child has already been exposed. The point is to find the source upstream and remove it.
Indiana's 2024 law lets utilities replace privately-owned portions of lead service lines without requiring landlord consent. A practical fix for the renter-blocked-replacement problem that has slowed nationwide LSL replacement under the EPA LCRI.
Background
A lead service line typically has two portions: the public-utility-owned portion from the water main to the property line, and the customer-owned portion from the property line to the home. In rental properties, the customer-owned portion has historically required landlord consent for replacement. Landlords often refused or delayed, which left tenants on lead pipes even when the utility was prepared to fund replacement of the public side. Indiana's 2024 law removed the landlord-consent requirement for the customer-owned portion.
Why this matters now
The renter-blocked-replacement problem is one of the largest practical bottlenecks in EPA LCRI implementation. Roughly 40 million U.S. households are renters; many of those occupy older housing stock most likely to have lead service lines. Indiana's approach — letting utilities proceed with replacement at the customer's request without separate landlord sign-off — is a model that other states are watching. Several have introduced similar legislation.
One thing I keep coming back to: essentially every American alive between roughly 1940 and 1985 carried a blood lead level that today's CDC would classify as elevated. Average pediatric BLL in the late 1970s ran 12–17 µg/dL — well over today's 3.5 µg/dL CDC reference value. We are still living through the long tail of that exposure, and most people in positions to make policy now grew up inside it.
I'll note up front: the public-health establishment doesn't always love how I frame this stuff. I've been told to soften my language. I've been uninvited from rooms. The framing that "ubiquitous historical lead exposure means most adults have a measurable lead body burden" is uncomfortable to people whose careers were built on protecting children prospectively. I get it. I'm still going to keep saying it because it's true and the scope of the problem requires that we be honest about it.
What it means in practice
Indiana's framework treats the LSL replacement as a maintenance action benefiting the occupant rather than a property modification, with the utility bearing the work and (typically) the cost. Property owners retain ownership of the new infrastructure. The legal framework parallels how utilities handle other shared infrastructure under easement and right-of-way doctrine.
For surface lead in your home — paint, ceramic glaze, brass fittings, dust, exterior environmental surfaces — modern fluorescence spectroscopy-based testing is the right consumer tool. Apply a methylammonium-bromide reagent (Fluoro-Spec from Detect Lead, the Lumetallix-branded reagent, or generic Chinese MABr products are all the same chemistry) and lead-bearing surfaces fluoresce green under a 365 nm UV flashlight. Single-particle resolution, no lab. LBP dust is detectable.
