1 Water Well Problems? Smells? Discolored water? Clogged pipes? Stains? Well Guard

2 926 Carolina Drive Lugoff, SC Phone: (803) Mission Statement Water is precious. With water supplies shrinking, water will replace oil as the premiere natural resource. Clean water is essential to a high standard of living. Poor water quality negatively impacts every aspect of life. Precious groundwater resources must be managed and protected to ensure groundwater quantity, such as well yields, and groundwater quality with respect to damaging impacts. At Berry Systems, we believe everyone deserves clean water.

3 Well Guard is a well cleaning aid which is tested and certified to NSF/ANSI Standard 60 by NSF, The Public Health and Safety Company. Well Guard is used to clean wells which are clogged, producing odors, discolored water, and staining. The WellShield system dispenses Well Guard, a well cleaning aid, into the well, oxidizing the water column inside the well. A clean water well does not have clogs which damage associated equipment such as well pumps, water filtration peripherals, irrigation systems, and household appliances. With the WellShield system cleaning the well, there is no odor from hydrogen sulfide gas. The WellShield system also enhances filter performance by preventing clogs. Well Guard Benefits Certified to NSF/ANSI Standard 60 as a well cleaning aid Automatic daily cleaning of the well with minimal chemical usage Oxidizes the water in the well Cleans clogs which can cause discoloration in well water and water tanks Eliminates clogging and blockages in pipes, pumps, micro irrigation lines, filters and softeners. Cleans clogs from the well which may lead to unpleasant odors in well water. Well Guard is NSF certified as a well cleaning aid for potable water. wells.

4 Background on NSF and the Drinking Water Additives Program NSF International, The Public Health and Safety Company was established in 1944, as an independent, not-for-profit, third party organization dedicated to the protection of public health and safety. NSF has more than 300 employees consisting of engineers, chemists and toxicologists who develop U.S. national standards and provide independent product testing and certification services for products that impact food, air, water, and the environment. NSF is a World Health Organization (WHO) Collaborating Center on Drinking Water Safety and Treatment, as well as for Food Safety. NSF involvement in the evaluation of drinking water chemicals began in 1985, when the U.S. EPA granted an NSF-led consortium of stakeholders the responsibility to develop consensus, health-based, quality specifications for drinking water treatment chemicals and drinking water system components. EPA also requested development of a product testing and certification program that would allow for independent product evaluations for use by states, cities, and water utilities, as a basis for product acceptance and use. The original goal of the standard and certification program was to develop a preventative mechanism for selecting treatment chemicals that would not contribute harmful levels of contaminants to drinking water. The standards and the certification program were designed to be dynamic, to change as regulations change, and to constantly be tied to the requirements of the Safe Drinking Water Act and its drinking water quality regulations. In 1988, EPA terminated its informal chemical additives advisory program upon completion of the NSF standards and successful launch of the NSF product certification program. Today, NSF provides testing and certification services for thousands of products from more than 80 countries. NSF publishes its listings on its web site at

5 Clean your well! Most well water looks great when the driller leaves. However, rust-colored deposits and clogs can build up on well screens, pipes, and plumbing fixtures resulting in odors, stained surfaces, and clogged plumbing or irrigation systems. Layers of insoluble iron block screens and pipes, reducing well yields and water pressure. Traditional cleaning methods work temporarily until clogged. The key to clean water is a clean well. The WellShield system is unique in this approach. Well Guard is NSF certified as a well cleaning aid for potable water wells. The number one reason for loss of production and abandonment of groundwater wells is clogging. Well Guard attacks these clogs and cleans your well of clogging which can lead to staining, and odors. Well Guard is the only chemical approved for use in the WellShield system. Should you be concerned about the quality of the water in your well, Underwriters Laboratories will test the water according to their UL Drink Well program. See for more information. We recommend you use an alternate source of water for drinking and food preparation until the well and pipes are free of any debris and the water is consistently running clear. Clogging of the well is eliminated and the well is effectively cleaned at Well Guard levels well below the NSF maximum use level of 3mg/L. The WellShield System is the most effective system for cleaning a well. The system runtime is dependent upon the well construction and the level of clogging in the well. A clogged well will deposit debris and ferric hydroxides in the well proper, the pump, the riser, the supply line, and into the plumbing in the residence or irrigation system in an amount directly proportional to the level of clogging. When the clogging in the well begins to be broken up, these particles will come loose and migrate downstream. Be aware of the resulting debris and protect any peripheral water filtration devices you may have accordingly.

6 Use Well Guard with A WellShield System The WellShield System dispenses Well Guard into the well water, oxidizing the water column. Utilize the WellShield Selection Program (at to choose the correct model, calculate the system run time, and project annual Well Guard usage. To fill WellShield Dispenser with Well Guard Warning: Close isolation valve before servicing WellShield dispenser. Do not remove cover when vessel is pressurized! Open air relief valve and allow pressure to drop to zero. Remove cover. Fill WellShield dispenser to top of center cap. Insure O-ring is seated in O-ring groove on dispenser. Replace cover. Replace and hand tighten air relief valve. WellShield Dispenser Cover Caution: Do not use any product in the WellShield dispenser other than Well Guard. Read and follow all instructions that accompany Well Guard before opening the container. Well Guard Replacement As the quantity of Well Guard is reduced in the WellShield dispenser, the performance of the system can be reduced. WellShield operates optimally when the Well Guard level is at least half full. For effective cleaning, do not allow Well Guard to empty below half of the internal reservoir capacity. Monthly inspection of Well Guard level is recommended until operator becomes familiar with Well Guard consumption. Well Guard: Order HS2LB Order HS30LB Well Guard (2 lb. jar) Well Guard (30 lb. pail) Well Guard dissolution rate is approximately 5 mg/kg/l in a single pass through the WellShield dispenser (This is dependent upon the amount of Well Guard tablets in the system and their relative size at the time of measurement). Concentrations of 1-3 ppm total Well Guard are adequate for effective cleaning. Do not engage the well pump for minutes for effective cleaning. Chemical presence should not be detectable by smell. Use the test kit to check Well Guard residual, which should not exceed 3 mg/l.

7 Cleaning Frequency Calculation: Should the well be cleaned once or twice per day? The average daily water usage in the United States is 168 gallons per person. If more water is standing in the well than will be used in 24 hours, the well should be cleaned once daily. If more water is used daily than is standing in the well, the well should be cleaned twice daily. To determine whether to clean the well once or twice daily, use the following calculations. Overall Depth of well Static Water Level Water Column Depth Casing Diameter Inches (A) (B) (C) = A-B Gallons per Foot Multiply the Water Column Depth (C) above by the gallons per foot for the corresponding casing diameter. This determines the total number of gallons standing in the well. Next, divide the total number of gallons in the well by the total number of people in the residence. Is the number greater than or less than 168? If the number is greater than 168, clean the well once daily. If the number is less than 168 clean the well twice daily. Should cleaning the well once per day not suffice in terms of water quality, clean twice daily. Irrigation in addition to potable water usage will normally require twice daily cleaning. Consider the following installation for a residence of 2 people who do not irrigate. The well is 200 deep with a static water level of 60 and the casing diameter is 6. Overall Depth of well Static Water Level Water Column Depth _200_ (A) 60_ (B) _140_ (C) = A-B 140 (feet of water) X 1.5 (gallons per foot for a 6 casing) = 210 gallons in the well 210/2 (people in residence) = 105 gallons 105 < 168 Therefore, clean twice daily.

8 Cleaning run time: Set the unit run time in accordance with the WellShield Selection Program (at brochure.html). Following initial cleaning cycle, check Well Guard residual level at the tap closest to the well using Well Guard Test Kit for bromine according to package directions. A severely dirty well is not likely to register any Well Guard residual. Residual levels should not exceed 3 mg/l. If the residual level does exceed 3mg/L, reduce run time. Pump water to waste. Wait 12 hours. Following next cycle check residual again. One(1) hour after cleaning, the residual should be 0.2 mg/l or less. Rest the well for minutes for effective cleaning. Chemical presence should not be detectable by smell. Never use a runtime that yields a residual higher that 3 mg/l. Once the well has been cleaned, reduce run time to achieve a cleaning level approaching 1 mg/l in accordance with the WellShield Selection Program. The goal is to maintain the well with minimal chemical intervention. Well Guard Residual Test Kit WELL GUARD The WellShield system comes with a kit for determining the chemical residual level in the well water. The Well Guard Test Kit Instructions are as follows: 1. Remove cover from tester. 2. Hold tester with colorimetric chart facing you. Fill reservoir on the right with water from the well. 3. Remove DPD No. 1 test tablet from the foil package. Drop the tablet into the water in the tester. 4. Place cover onto tester and seal. Shake tester and wait 30 seconds until tablet completely dissolves. 5. Match water color in tester to the pink graduation on the right. Read residual. Ensure that residual does not exceed 3 Br 2 mg/l. For chemical testing only! Never eat tablets! Keep out of reach of children. Read the test results when the tablet has completely dissolved and 30 seconds have passed. Do not retain the chemicals in the reservoir and read the results several minutes or hours later. Any later result will not be accurate! Discard contents and rinse reservoir. Based upon the reading, the run time may need to be adjusted. See After Install Check List included with the installation instructions for further instructions on obtaining the best chemical cleaning level for your well.

9 After Installation Check List Important Information for Well Owner To clear the well and distribution piping of the clogged materials which have built up over time in the well and plumbing, please follow these simple directions: Use the WellShield Selection Program (at to calculate the run time for the well and program the timer accordingly. Each morning run the spigot closest to the well until the water runs clear. Then run water from each faucet in the house until the water runs clear. This is to be done daily until the well and pipes are free of any clog debris. Depending on the level of clogging at your site, this regimen will need to be done for a period of several days to several weeks. Check the residual level of the Well Guard in the water at the kitchen tap using the test kit enclosed in the installation kit. Ensure that the residual level does not exceed 3 mg/l. Should you get a reading in excess of 3 mg/l go to the well and run water to waste until the level is reduced and reduce the run time accordingly. One hour after the cycle runs, a residual of 0.2 or less is best. The timer should be set accordingly to maintain this level. Once the WellShield System has cleaned the well and pipes, the run time may be reduced to maintain a clean well. Up to a 50% reduction in run time may be sufficient. You are the well operator. Many variables influence the cleanliness of a well. Use the test kit to monitor your well water residual and adjust the runtime as needed. Never use a runtime that yields a residual higher than 3 mg/l. Note: (See Well Guard instructions for additional information on testing for the Well Guard residual.) Should you ever smell the chemical, test the water using the residual test kit and reduce the run time to reduce the residual level. Also, should the well foul, immediately check the canister to determine whether it has a sufficient quantity of Well Guard in it. If the canister is ½ full or better, an upward adjustment of the timer may need to be made. Any adjustments to the timer should be done in small increments and sufficient time, at least a few days, should be allowed to lapse before additional adjustments are made. An exception to this would be a high residual reading where a larger downward adjustment might be required. Contact Berry Systems, Inc. if further information as needed.
