Zinc

Metals

1.64

PPM

Zinc is a naturally occurring metal commonly used as a protective coating for other metals used in plumbing materials. High zinc concentrations may impart a bitter or metallic taste to drinking water.

Total Dissolved Solids

Properties

362

PPM

Depending on the ions present, high total dissolved solids (>500 mg/L) can lead to excessive scaling in water pipes, water heaters, boilers, and household appliances such as kettles and steam irons, which can lead to shorter service lives of these appliances.

Sulfate

Inorganics

23

PPM

Sulfate can form scale on plumbing fixtures and the walls of pipes. Indirectly, sulfate that fuels sulfur-reducing bacteria creates the conditions for producing hydrogen sulfide gas, which can be corrosive to pipes.

Iron

Metals

0.094

PPM

Iron in your tap water may indicate corroding plumbing or the presence of iron bacteria—organisms that consume iron to survive. Iron deposits and the slimy biofilm created by iron bacteria clog plumbing, water-using appliances, heaters, and treatment equipment, reducing their effectiveness and lifespan. These conditions may also increase the corrosivity of your tap water, causing pipes to release metals. If the iron in your tap water is the result of corrosion, your plumbing may also be leaching more hazardous metals like lead.
