Service line testing for homes and buildings
Ordered draw sequences that indicate which segment of the supply path is contributing. Independent of every excavation contractor.
Service-line investigation
Sampling can help distinguish a fixture-level issue from lead contributed farther upstream in the water path.
Sampling design matters
First-draw, flushed or sequential samples can be selected depending on the lead question being investigated.
Measured lead concentrations
Accredited laboratory analysis reports the lead concentration associated with each sampled location.

Questions clients commonly ask
- How do I know if my property has a lead service line?
- Can a lead service line affect every faucet equally?

Professional Water Service Line and Lead Testing
The water service line runs between the street main and the building, and it is the segment property owners can inspect least easily. Ownership is frequently divided along its length and records rarely describe what is physically in the ground.
Olympian Water Testing provides professional lead in water testing for homeowners, boards, managing agents, building owners and property buyers throughout New York, New Jersey and Connecticut.
Establishing What the Supply Path Contains
Where the pipe is reachable at the wall, material can often be assessed by appearance, by whether a magnet holds and by a careful scratch. That establishes the material at that point alone.
Lead bearing components also remain in current use beyond the service line, including brass faucet bodies, angle stops, mixing valves, ball and gate valves and pipe fittings, so the assessment covers the whole path rather than one segment.
Why Lead Is Sampled as a Sequence
Lead is drawn as an ordered series along the supply path. The first draw reflects water standing in the fixture and the branch line behind it, and successive draws reach progressively further upstream toward the riser and the water service line.
The pattern across that series indicates which segment is contributing, which is the finding that determines whether the appropriate response concerns a fixture, a branch line, a riser or the water service line.
How the Sampling Event Is Conducted
Our highly trained and skilled laboratory technicians attend the property and conduct the sampling event. Where stagnation is required it is requested of the client and the elapsed hours are entered in the field record.
Outlet screens are left undisturbed during collection so particulate lead accumulating there is captured, and samples are handled under documented chain of custody with holding times observed.
Independent Assessment Before Committing to Work
Replacing a fixture, replacing a branch line or riser, and replacing the water service line are three entirely different undertakings, and the sequence indicates which is warranted.
Olympian Water Testing has conducted this work since 1991 under NELAP accredited laboratory analysis, and enquiries are received at any hour of any day.
