Preserve the useful detail
Use the official address lookup, mailed notice, service-assistance form, certified sampling guidance, and visible entry only as instructed.
The decision on display
Do not transfer the hazard
Do not identify material from appearance alone, disturb suspected lead piping, or use fear to sell broad replacement.
Make the proposed work comparable
Separate system and owner portions, confirmation, sampling, contractor approval, route, permits, flushing, surfaces, and final records.
