Inquire NowIron and manganese Fe/Mn are common in groundwater supplies used by many Forest Service water systems. Iron is the more frequent of these two contaminants, but they often occur together.At higher concentrations, precipitated iron residue may buildup on the softening resin, decreasing the efficiency of the softener. Washing the resin with
Inquire NowIron and manganese are frequently detected at elevated concentrations in CDD leachate. Both of these elements are abundant metallic elements and are readily mobilized in the chemical environment created in a landfill. Thus, these constituents are commonly present in the leachate.
Inquire NowThe regulations call for dissolved iron in treated drinking water to be maintained at or below 0.3 mg/L, and dissolved manganese to be maintained at or below 0.05 mg/L. Above these threshold concentrations, iron and manganese can turn drinking water rusty, create stains in laundry, and cause discoloration of porcelain sinks and tubs.
