Sanitation Procedure
TOO MUCH CHLORINE IS BETTER THAN
TOO LITTLE: **
In situations where it is inconvenient to determine depth
of water or diameter of a drilled well, a minimum of 1/2
gallon of household bleach may be used for wells up to
8 inches in diameter with estimated to be less than 80
feet deep; 1 gallon should be used for similar size wells
with water deeper than 80 feet. In case of a well yielding
more than 50 gallons per minute, special procedures are
required. Seek the advice of a certified water treatment
specialist.
Wait a day or two before you have another sample tested.
Do not take a sample for testing if the odor of chlorine is
still present in water.
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.
Plumbing Line Sanitation Only:
When installing an ultraviolet disinfection system, a pre
-
filter with sump may serve as a source to sanitize the
water lines only. For whole system disinfection follow
procedure as outlined above.

TABLE 2
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 chlorination
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 2 shows how many pellets too use
per 100 feet of water in various diameter wells.
