Sequential draw sampling that separates the fixture from the riser from the service line. Departure location at 665 88th Street, Brooklyn.
Older urban properties can combine long service lines, legacy plumbing and many individual fixtures.
Testing evaluates the water at the faucets and outlets that occupants, employees or visitors actually use.
Lead, bacteria, PFAS, VOCs, metals, Legionella and other parameters can be selected according to the property and concern.

| Era | Common supply materials | Testing implication |
|---|---|---|
| Pre 1900 | Lead service connections, galvanized interior lines | A draw sequence separates the service line from the branch line or riser |
| 1900 to 1930 | Galvanized steel with lead tin solder at joints | A full draw sequence, aerators left in place |
| 1930 to 1960 | Mixed galvanized and early copper | Transitions between materials are common finding points |
| 1960 to 1986 | Copper with lead tin solder throughout | Solder contribution appears in the later draws of the sequence |
| Post 1986 | Copper or plastic, lead free solder | Brass fixture components remain a contributor |
Brooklyn row house stock rarely contains a single generation of plumbing. Supply systems in these buildings have typically been altered in sections across a century, driven by what failed, what a renovation reached and what a budget covered, leaving several eras of material connected in series.
Olympian Water Testing provides professional water testing for row house owners, buyers, boards and managing agents across Brooklyn, working from a departure location at 665 88th Street.
A supply path in these buildings may include an original service connection, branch lines and risers replaced at different times, branches added when a garden level unit was created, and capped stubs left in place from work long since forgotten.
Lead bearing components remain in current use as well, including brass faucet bodies, angle stops, mixing valves, hose bibbs and pipe fittings, so a recently renovated kitchen does not by itself resolve the question.
A single sample from a convenient tap therefore describes that tap. Establishing what the property as a whole is delivering requires a scope designed around its actual configuration.
Olympian Water Testing begins with a walkthrough of the cellar, the risers and the point where the service connection enters at the wall, because what is physically present frequently differs from what the deed, the listing and the renovation records describe.
Lead is then collected as an ordered sequence of draws along the supply path. Successive draws reach progressively further upstream through the branch, the riser and toward the water service line, and the pattern across the series indicates which part of the building is contributing.
Where a house has been divided, separate branches serving separate units are treated as separate questions. Where a defined stagnation period is required, preparation instructions are provided before the sampling appointment.
Reporting identifies each sampled location, the measured concentration and the laboratory reporting information needed to compare results across the building.
The distinction between a fixture contribution and one originating further upstream is the finding that determines scope of work, and it is stated plainly rather than left to inference.
Results are presented so they can be taken directly to a plumber, an architect, a buyer or a lender.
Owners undertaking restoration work benefit most from establishing the position before committing, since replacing a fixture, replacing a riser and replacing the water service line are entirely different projects.
Olympian Water Testing has worked across this stock since 1991, with NELAP accredited laboratory analysis and accredited results provided.
Enquiries are answered at any hour of any day, and one of our consultants determines parameter selection before the sampling event is arranged.
Olympian provides professional on-site sampling and accredited laboratory analysis for residential, commercial and institutional properties.
