The strong chlorine solution can damage these filters. Before you begin, disconnect all carbon filters and reverse osmosis units attached to your household water lines. Shock chlorinating a water supply system can potentially damage components such as pressure tanks, some filters and filter media, and other treatment devices. Protecting components of water supply and treatment devices.In Step 3 of the shock chlorination process below, you will need to turn the power back on, but be sure to turn the pump circuit breaker off again before replacing the well cap or cover (Step 6). Before removing the well cap or cover, turn the pump circuit breaker off. Preventing electric shock from the water pump.Make sure that no one in your home uses the water for any purpose during the 12 to 24 hour treatment. Chlorine should have enough contact time to kill the bacteria.Make sure that children and older adults do not consume tap water during treatment. Arrange for an alternative source of drinking water. High chlorine levels in water after shock chlorination.Mix and add chlorine solution in a well-ventilated area. Because of the volatile and corrosive nature of the concentrated chlorine solution, it is important to wear appropriate clothing, including goggles, a protective apron, and rubber gloves and boots. Concentrated chlorine solutions for shock chlorination can be dangerous.Should you decide to shock chlorinate your well yourself, take the following precautionary measures: A licensed well driller is trained to shock chlorinate. Shock chlorination is used to remove bacterial contaminants from well water, well casings, holding tanks and the whole water supply system. What Precautions Should Be Taken Prior to Shock Chlorination? Well water for drinking should be tested for arsenic after shock chlorination to make sure the arsenic concentration is at a safe level (less than 10 ppb).Well casings, holding tanks and pipes should be flushed thoroughly until no residual levels of chlorine are found.Do not leave chlorine solutions inside well casings for longer times than prescribed (12-24 hours).Do not use either acid or alkaline bleach solution.If well owners have detectable levels of arsenic in water, the following steps may be useful: Similarly, because chlorine is a strong oxidant, it could dissolve arsenic from sediments and release it into the groundwater. Oxygen helps in dissolving some of the arsenic contained in sediments. When the water table is lowered due to pumping of groundwater, the sediments in groundwater are exposed to oxygen. Arsenic occurs naturally in some bedrock and aquifer sediments in the southern coastal plain (SCP) region of Georgia, and it has been found in drinking water from some private wells in this region. Shock Chlorination and Temporary Arsenic ReleaseĪlthough shock chlorination will sanitize wells, it may temporarily increase the arsenic levels of water in areas where aquifer sediments contain high levels of arsenic (WDNR, 2008).

Another option is to install a continuous disinfection treatment system. The source(s) of such contamination should be identified and eliminated by a licensed well driller/contractor. Shock chlorination is NOT a recommended method for treating recurring bacteria problems. inadequate grouting or other faults during well construction.absence of a well cap or an improperly placed or loose well cap.a pathway for surface water entry to a well, such as:.if the well has iron bacteria or sulfur-reducing bacteria symptoms like slime (biofilm) or odorĪfter shock chlorination, bacterial contamination may reoccur if a source of contamination persists, such as:.if well water becomes muddy or cloudy after a rain.whenever the well is surrounded by flood waters (standing water around or covering the well casing).if a well system is opened for any installation, repair or maintenance.if annual water test results indicate the presence of bacteria.upon completion of a new well or when an unused well is returned to service.Shock chlorination is the most widely recommended means of treating bacterial contamination in home water systems. Shock chlorination is the process by which home water systems such as wells, springs, and cisterns are disinfected using household liquid bleach (or chlorine).
