Turbidity and physical parameter testing
Measured alongside the parameters that give it meaning, with prompt handling so the sample describes the water as it was drawn.

Cloudiness can reflect suspended particles, sediment or other conditions that deserve targeted testing.
Testing may include iron, manganese, turbidity, sediment-related parameters and other analyses based on the condition observed.
Sampling multiple locations can help determine whether the condition is isolated to one fixture or occurs more broadly.

Turbidity measures cloudiness and says nothing about what is causing it
Professional Turbidity and Physical Parameter Testing
Turbidity is an optical measurement of how much light is scattered by material suspended in water, reported in nephelometric turbidity units. It quantifies the quantity of suspended material.
Olympian Water Testing provides professional turbidity and physical parameter testing for homeowners, building owners, managing agents, boards and institutional clients throughout New York, New Jersey and Connecticut.
What Turbidity Establishes
Clay, silt, rust, mineral precipitate, organic matter and biological material all scatter light, and the instrument reports a single value covering whatever is present.
Identifying the material requires parameter specific analysis, which is why turbidity is selected alongside the parameters capable of explaining it rather than on its own.
Why Turbidity Is Read With Other Parameters
Suspended material can shield organisms from disinfection and can indicate that something upstream has been disturbed, which is why bacteriological indicators are frequently selected alongside it.
Where the history of the property or the event supports it, metals are selected as well, since a disturbance capable of mobilizing sediment can mobilize other material at the same time.
How the Sampling Event Is Conducted
Physical parameters change as soon as a sample is disturbed or allowed to stand, so our highly trained and skilled laboratory technicians handle and transfer these samples accordingly.
The appearance of the water is documented at the sampling event alongside the measured value, and holding times are observed for every parameter selected.
Independent Testing Since 1991
Olympian Water Testing has conducted physical parameter work across the region for thirty five years, with NELAP accredited laboratory analysis.
Olympian Water Testing investigates discolored water by combining observations at the property with targeted laboratory analysis. The distribution of the symptom, hot-versus-cold behavior, water source and plumbing history help determine which parameters and sampling locations are most useful.

Common questions
What is turbidity in drinking water?
Turbidity describes cloudiness caused by suspended particles that scatter light. It is a physical water-quality measurement rather than the identity of a specific contaminant.
What causes high turbidity at a faucet?
Sediment, corrosion products, main disturbances, plumbing work and source-water conditions can all contribute, so the cause depends on the property and timing.
Can water be clear and still have other contaminants?
Yes. Low turbidity does not rule out dissolved metals, PFAS, bacteria or other contaminants that are not visible.
Should turbidity be tested with iron or manganese?
Often it is useful to pair physical measurements with parameters that may explain the suspended or discolored material, such as iron and manganese, depending on the situation.
