The Department of Agriculture recommends that when a well has iron bacteria or other slime-producing organisms, that the well be shock chlorinated (sanitized) periodically to prevent plugging of the water pump, pipes, pressure tank, and valves, with biofilm.
If plugging occurs, it will reduce your water flow-rate and pressure resulting in an inadequate supply of water. As a result, water-using devices such as, toilets, showers, washing machines, dishwashers, livestock-waterers, filters, softeners, etc. will not be able to function properly.
Periodic use of "Well-Sanitizer" tablets will ensure that the slim-producing organisms present in your well won't interfere with the proper operation of your water pump and water pressure system.
How To Sanitize a Water System
When a water system is infested with iron and/or sulfate-reducing bacteria, shock chlorination treatment is recommended to control these slime-producing organisms. This sanitizing procedure is easy to perform.
Calcium Hypochlorite Tablets are what is recommended rather than household bleach and other commercial solutions containing weaker concentrations of sodium hypochlorite. The chlorine content in these messy liquids ranges from 3 to 15 percent, and due to the unstable nature of these compounds the strength of the chlorine weakens so that at the time of use, they may not contain anywhere near the labelled amount of available chlorine.
This procedure of shock chlorination will work for wells with a nuisance bacteria problem. If the water still has a foul odour after chlorination, particularly in the case of sulfate-reducing bacteria, the entire procedure should be repeated as such an odour is a sign that not enough chlorine was used for sanitizing.
When the correct quantity of chlorine is used, raw well water will have a chlorine odour, but the odour will disappear shortly after the well has been pumping continuously.
Note: This procedure will not completely eliminate iron and sulfate reducing bacteria from your water system, but will hold it in check. Therefore, shock chlorination will have to be repeated from time to time, in order to control the problem. Aztec's Well-Sanitizer chlorinating pellets can be used for well water, storage tank, or cistern sanitization. The number of pellets used will depend on the amount of water in the system to be sanitized. To produce a 200 ppm chlorine concentration, use one-quarter (1/4) pound chlorination pellets for each 100 gallons of water in the system (1/4 lb/100 gall = 115 pellets or 1/2 cup). The table (see below) shows how many pellets to use per 100 feet of water in various diameter wells.
Drilled Wells and Large Diameter Bored Wells
|Well Diameter - Inches||Cups of Pellets||Number of Pellets|
|8||1 & 1/4||285|
