No. It is not uncommon for groundwater in the Longview-Kelso area to contain some amount of iron and manganese.
Iron & Manganese Stains
Left untreated, raw water containing iron and manganese will oxidize when exposed to air (as it leaves the tap) and these minerals will change from a colorless, dissolved form to red-brown (iron) or brownish-black (manganese) particles. If not removed from the water, iron can cause reddish-brown staining of:
Manganese acts similarly but causes a brownish-black stain. Soaps and detergents do not remove these stains, and use of chlorine bleach can intensify the stains.
Iron & Manganese Removal
The City treats for iron and manganese removal in order to prevent the problems associated with staining and to prevent the build-up of iron and manganese deposits which can collect in pipes, pressure tanks, water heaters, and water softeners. Temporary water quality issues including discolored water have been experienced in some areas of Longview, particularly in older areas of town where the distribution system is made up of cast iron and galvanized water main pipe. The City is actively working to resolve this problem and continues to flush areas of concern on a regular basis until a long term solution can be implemented.
