Water is blackish hue to almost black and then clears

Water color can vary from blackish hue to almost black when first drawn but clears upon standing for 24 hours.

Indicates a significant amount of dissolved manganese in the water.

Treatments:

Small amounts of dissolved iron and manganese can be removed with a common water softener. The water softener manufacturer should have several models that list the amount of iron removal in grains per gallon.

High amounts of dissolved iron and/or manganese can be removed using a properly rated iron and manganese treatment device. Cartridge type devices are available to remove amounts of iron and manganese less than 5 milligrams per liter (same as 5 parts per million).

 Always have your water tested and base any treatment on those results. Our Water Quality Interpretation Tool will aid you in your decisions.
