A few water contamination symptoms are evident in the buildup or staining found on sinks, bathtubs and other water fixtures. Below are a few of the most common and their causes.
Evidence of Common Water Contaminants
Common Cause: Manganese
Manganese (Mn) is often found in surface water and groundwater sources. Usually in combination with iron. The EPA has set Secondary Maximum Contaminant Levels (SMCL) for manganese at 0.05 mg/L, but the EPA does not enforce these guidelines. High levels of manganese can cause black staining in and around water fixtures and often signals high levels of iron mineral deposits in water.
Manganese buildup can reduce a home’s water pressure, and increase plumbing maintenance costs. Levels of manganese above the SMCL can cause staining of laundry and water fixtures and a give a sharp, bitter taste to water.

Common Cause: Water pH balance is low
Blue-green stains on bathroom and kitchen fixtures are often the result of a low water pH balance causing your home’s water to become acidic. The blue stains are caused by particulates like iron, manganese, copper, lead and zinc eroded from municipal and home plumbing as acidic, corrosive water travels through the pipes.
The best way to identify the pH levels in your water is to have simple water quality test conducted. Click here to contact a Juturna water testing specialist.
Orange or Reddish Staining
Common Cause: Iron or Sediment
Orange or reddish stains and buildup in tubs, sinks, washing machines and other home water fixtures is often the result of higher-than-recommended water iron levels. Iron concentrations above 0.3 mg/L can result in problems like stained laundry, toilets and other plumbing fixtures.
Metallic tasting water and reduced water pressure can become evident at iron levels above the EPA’s Secondary Maximum Contaminant Levels of 0.3 mg/L. Sediment/Iron testing is required to test for the difference. If you’d like to speak with a water testing professional, get in touch with us here.
White Scaling or Build Up
Common Cause: Hard water causing mineral build up
Hard water refers to water containing higher than normal concentrations of minerals like calcium and magnesium. These mineral deposits in your home’s water buildup inside your water heater, plumbing and any surfaces that regularly contact water. Hard water makes surfaces more difficult to clean and will even help your homes plumbing and water appliances corrode and need repair more often. Learn more about water softening here.
