Estimated Life of WH5 Iron filter Cartridge: Iron Equivalent Level in Water Total Gallons Water Used 250 GPD (946 LPD)(four people) Iron (Fe), Manganese (Mn), and Hydrogen Sulfide (H 2 S) can present a very complex challenge to drinking water treatment. The combination of these contaminants is sometimes referred to as the “troublesome trio.” In Canada and the United States the maximum permitted concentration in drinking water is 0.3 ppm for iron, 0.05 ppm for manganese and hydrogen sulfide being a gas is limited to 3 Removing iron and manganese from drinking water instead of sequestration it is recommended if the water contains over 0.3 ppm of iron or 0.05 ppm of manganese.
The barley is coaxed into growing by a series of immersions in warm water at 16°C, Lightly peated: 1-5ppm (typical Speyside malt uses 2ppm) A tool called a 'Fal' or 'peat iron' is then used to cut and extract the peat itself in long bricks.
Health and Water Quality Iron is not considered hazardous to health. In fact, iron is essential for good health because it transports oxygen in your blood.

I had my well water tested and I have ~2ppm iron with a hardness of about 21. I was told my PH was ok. They tried to sell me a $1500 system for the removal of iron and general filtering along with an $800 electric current conditioner to help with the hardness.
Ferric and Ferrous Iron can easily be confused so the best way to remember the difference is their endings. Ferric ends in “I-C” because it is the iron you can see Iron is one of the most abundant elements on earth. It is an essential element for humans, and it is used in a variety of industrial processes. It is also found in drinking water. High levels of iron can be fatal, but the amount found in drinking water is typically too low to be dangerous. This water softener can remove ferrous and ferric iron up to 8 PPM from your well water. Along with iron, it can also remove calcium, manganese, and magnesium from water, and the total score of removing hardness goes to 95 GPG. Also, it reduces the consumption of soap and detergent into the shower and laundry, respectively.
