For Personal Well Water if any Treatment is required most can be handled with a Sand Filter available just about any Plumbing or Home Depot, etc. if your well has Taste and Oder problems try a Charcoal Filter for the GPM (gallons per minute) of the Pump flow at Maximum. Really bad Taste and Oder can additionally be treated with Potassium Permaganate (KMnO4)Individuals trying to purchase this will have to fill out fedgov paperwork because its on the homeland insecurity Watch List last I knew a few years ago. Treat KMnO4 with care. Make sure you get an MSDS
A Feeding System will be needed for the correct dosage of KMnO4.
Whatever you do, DO NOT mix your Potassium Permanganate with Glycerine and toss it in the garbage.
