Read the pattern
Use SPU's current address research path, retain the date and classification, review any prior sampling or plumbing records, and note which portion or component the result actually covers.
Decision terrace 12
Move from evidence to a bounded authorization
Hold the safety line
Do not scrape, cut, sand, or disturb suspected material to identify it. Follow current SPU and health guidance for flushing, sampling, and qualified work.
Place the Seattle boundary
A public monitoring result cannot classify a private connection, faucet, solder joint, or building pipe. Neighborhood age and visual appearance are not adequate address evidence.
Write the visit
Any proposal should separate record research, field confirmation, certified sampling, private and public segments, access, replacement triggers, permits, flushing, surfaces, and post-work documentation.
Keep the closing evidence
Retain laboratory and field records, SPU correspondence, photographs, installed material, inspection, and any updated address status. Avoid a broad safety claim from one result.
