REMEMBER - To make your water supply safe:

- Locate your well properly.

- Protect it from surface contamination.

- Test water periodically for coliform bacteria. (Home-yearly, Farm-2X yearly)

- Chlorinate, or filter and disinfect the water if necessary.

When installing an ultraviolet disinfection system, a prefilter with sump may serve as a source to

sanitize the water lines only. For whole system disinfection follow procedure as outlined above.

How to Sanitize a Water System Using Well Sanitizer Pellets

Table 1

Well Diameter Inches Weight of Pellets lbs. - oz. Cups of Pellets Number of Pellets

* To produce a 400 P.P.M. chlorine dosage

NOTE:

Pellets Weight = 1.14 gram each, 25 pellets/oz., 400 pellets/lb.

1 cup of pellets = 1/2 lb., or 200 pellets, or 8 oz.

To produce a 400 P.P.M. chlorine concentration, to sanitize a water system, use one-half (1/2) pound chlorina-

tion pellets for each 100 gallons of water in the system (1/2 lb/100 gal= 8 oz/100 gal= 200 pellets/ 100 gal= 1

cup pellets/100 gal). Table 1 shows how many pellets too use per 100 feet of water in various diameter wells.
