Raw Water
PH 5.7
Iron: 6569 ppb = 6.569 ppm
Manganese: 76.2 ppb
Total Coliform: Present; not a health risk, but indicates conditions where pathogenic bacteria could easily be introduced and thrive
E.Coli: negative
No detectable (nearest ppm) hydrogen sulfide or carbon monoxide off gassing
No undesirable anaerobic (oxygen deficient) conditions presently exist

Answer: There are a few ways to approach this, but the best approach is the one that is most effective at combating these problems, and available at the lowest cost to you. You have a low pH that requires correction, iron and manganese to be removed, and you may as well disinfect the water at the same time. To do this you can incorporate a chemical injection system, mixing soda ash (used to correct pH), and chlorine (used to oxidize the iron and manganese and provide disinfection of your water). You should follow this up with a 120 gallon retention tank to provided the required contact time. After the retention tank install a 2.5 ft3 Greensand-Plus filter. This filter will use any residual chlorine as a regenerate, and polish and iron and manganese not removed during the injection of chlorine (oxidation) process upstream. In last position, a 1.5 ft3 backwashing carbon filter will remove any injected chlorine from the household water supply. Price of all of this equipment would be in the range of $2500 to $3000 delivered.
