Find the cause of discolorationLaboratory testing can separate an aesthetic complaint from measurable metals, sediment or other water-quality conditions.
Target likely contributorsTesting may include iron, manganese, turbidity, sediment-related parameters and other analyses based on the condition observed.
Compare relevant outletsSampling multiple locations can help determine whether the condition is isolated to one fixture or occurs more broadly.

Iron and manganese testing

The shade and the staining narrow the cause before any bottle is opened

01
Describe the color and where it lands
Rust orange, tea brown, gray, yellow or black speckling all point in different directions, and so does whether laundry and porcelain are staining.
02
Establish hot side, cold side or both
Discoloration confined to hot taps points at the heater and its anode rather than at the supply, which changes the scope entirely.
03
Check whether it clears and how fast
Water that runs clean after a minute behaves differently from water that stays discolored, and the difference is diagnostic.
04
Select points that test the theory
Sampling is aimed at confirming or ruling out a specific cause rather than collecting bottles at convenient taps.
05
Record the appearance alongside the values
Field notes describe what was visible and when it began, because physical parameters change the moment a sample is disturbed.

Professional Testing for Iron, Manganese and Discolored Water

Discoloration in tap water is most often caused by iron, manganese or sediment returned to suspension by a disturbance within the distribution system or the property's own piping.

Olympian Water Testing investigates discolored water for households, renters, owners, managing agents and boards across New York, New Jersey and Connecticut.

What Color and Staining Indicate

Yellow to orange discoloration commonly indicates iron, brown to black indicates manganese, and a tea colored tint on a well property frequently indicates tannins. Milky water that clears from the base of a glass upward is generally dissolved air.

Iron and manganese are addressed under secondary drinking water standards, which are based on color, taste and staining. Both stain fabric and porcelain, and the staining pattern is recorded during the sampling event.

How the Investigation Is Conducted

The consultation establishes which taps are affected, whether hot or cold, when it began, whether it clears, and what occurred at the property or in the street beforehand.

Our highly trained and skilled laboratory technicians then perform the sampling event, with parameters selected to confirm or eliminate a specific explanation and the appearance documented alongside the values.

Understanding Our Reporting

Our reporting identifies the sampling points, the conditions and appearance recorded there, the analytical method, the reporting limit and the measured value for each parameter selected.

Whether a sample was collected during an active episode or after the water cleared is stated explicitly, since the two describe different conditions.

Independent Assessment of a Visible Problem

Olympian Water Testing has investigated discoloration across the region since 1991, with NELAP accredited laboratory analysis and accredited results provided.

Enquiries are received at every hour of every day, which matters for a condition that presents without warning.

Common questions

What does brown tap water usually mean?
It often indicates suspended sediment, iron or corrosion products, but the source may be the main, service line, building piping or water heater. Testing helps characterize the material rather than guessing from color alone.
Is brown water from hot water different from brown water from cold water?
It can be. A hot-water-only problem can point toward the water heater or hot-water piping, while cold-water discoloration may involve different parts of the system.
Why did my water turn brown after nearby street work?
Changes in flow can disturb sediment in mains or service lines. If discoloration persists or the cause is uncertain, sampling can help determine which parameters are elevated.
Can brown water be tested after it turns clear again?
Yes, but if the concern is intermittent discoloration, capturing the condition when it occurs may provide more useful information. Sampling strategy should reflect the timing and pattern of the problem.
