(a) Note.

(1) Liquid sodium hypochlorite in a 12-percent solution is often sold for use in water and wastewater treatment plants, and as a commercial bleach or for use in swimming pools.

(2) Utilizing a solution of this nature would call for a liquid (chemical) measure equal to one-half the volumes presented in column 5.

(b)(1) *EPA recommends a minimum concentration of 100 mg/l available chlorine.

(2) To obtain this concentration, double the amounts indicated.

(c) Where a dry chemical is used, it should be mixed with water to form a chlorine solution before putting it into the well.

17 CAR § 11-1003. Table 3 — How to Sanitize a Water System to 400 ppm using Autotrol's Well Sanitizer Pellets.

(a) Autotrol's pellets contain seventy percent (70%) calcium hypochlorite and thirty percent (30%) inert material.

Well Diameter-Inches	For each 100 feet of water depth use*
Weight of Pellets lbs. - oz.	Cups of Pellets	Number of Pellets

To produce a 400 PPM chlorine dosage

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

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

(b)(1) Autotrol Corporation's well sanitizer chlorinating pellets can be used for well, storage tank, or cistern sanitization.

(2) The number of pellets used will depend on the amount of water in the system to be sanitized.

(3) To produce a four hundred parts per million (400 ppm) chlorine concentration, to sanitize a water system, use one-half (1/2) pound chlorination pellets for each one hundred (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).

(4) Table 3 shows how many pellets to use per one hundred feet (100’) of water in various diameter wells.

(1)(A) Remove the cap or seal from the casing and measure the depth of the water in the well, then refer to the table to determine how many chlorine pellets should be used.

(B) In some instances, removing the seal to measure the water can be a difficult task, and it is easier to estimate well and water depth from well log or other records;

(2)(A) Remove well cap and determine if there is an unobstructed path from the top of the well to the water level.

(B) If it is not possible to remove the well cap, remove vent or sanitization access plug;

(3)(A) Drop one (1) pellet into the well and listen to hear if it hits the water.

(B) If the pellet hits the water, drop one-half (1/2) the number of pellets determined to be needed into the well.

(4) Mix the remaining pellets in a few gallons of water in a clean plastic container and pour the solution into the well;

(5)(A) In order to mix the chlorine thoroughly throughout the entire water system, it is necessary to recirculate the water in the well.

(B) This can be accomplished by connecting a hose to an outside sillcock that is located after the pressure tank.

(D) After about fifteen (15) minutes of recirculation of the water, a strong chlorine odor should be apparent.

(E) Turn off hose;

(6)(A) Bypass water softener and filters and open each water outlet in the water system until chlorine is present in water.

(B) This procedure assures that all the water in the system is chlorinated;

(7)(A)(i) Allow the chlorinated water to stand in the system for at least six (6) hours, and preferably overnight.

(ii) After this, open an outside faucet and flush system until water runs chlorine free.

(iii) Repeat flush operation on each faucet in system.

(B) Note.

(i)(a) Chlorine may break loose iron deposits, slime and organic material.

(b) This material will make the water run colored.

(d) Do not continue to run pump if water does not flow.

(ii) The high level of chlorine required to sanitize a water system is corrosive to most metals, and chlorine solution must not be allowed to remain in the water system more than thirty-six (36) hours before being completely flushed from system; and

(8) After the system has been completely flushed, perform a bacterial analysis on the water following all applicable procedures.

(d) Large-diameter bored wells:

(1)(A) Calculate the volume of water in well by determining the total cubic inches or cubic feet of water in the well.

(B) Each two hundred thirty-one (231) cubic inches of water is equal to one (1) gallon.

(2) Use one-half (1/2) pound of chlorine pellets for each one hundred (100) gallons of water in well;

(3) Dissolve pellets in clean, plastic pail and add to well;

(4) Pour two (2) cups of pellets directly into well;

(5) Connect a garden hose to a faucet in water system and run water from hose back down well;

(6) When strong chlorine odor is present in hose water, wash down sides of well with chlorinated water; and

(7) Proceed with steps listed in subdivisions (c)(6)–(8) of this section.

(e)(1) Springs and cisterns:

(A) Mix about one-half (1/2) cup of pellets in five (5) gallons of water; and

(B) Use this to scrub the walls of the spring box or holding tank.

(2)(A) With a constant flow of fresh water from the spring there is probably no way of detaining the chlorine solution in the reservoir for more than a few minutes.

(B) However, the chlorinated water should flow through the pipeline to disinfect the distribution system.

(3) Cisterns can be disinfected in the same way, but a source of clean water will be needed to flush the dirty waste out of the system.

(4) Note. This product is intended to sanitize a water supply system that has been temporarily contaminated and is not intended to solve a recurring contamination problem.

(f) Note.

(1) This part includes the minimum requirements for water wells constructed in Arkansas.

(2) For additional information pertaining to public or semi-public water systems, contact the Department of Health.

(3) For information regarding water use reporting, water rights, and ground water diversions, contact the Arkansas Natural Resources Commission, a division of the Department of Agriculture.

(4) For information on having your well water sampled, contact your local county sanitarian or county health unit.

(5) For additional information on water well construction or if you believe you have a complaint, contact the commission.

(6) For underground storage tank information, contact the Department of Energy and Environment.
