Quick Answer
SHOCK TREATMENT OF MULTIPLE WELLS: Yes, but with careful planning and equipment to prevent contamination issues. Shock treatment of multiple wells is possible, but the key is to maintain water flow rates and prevent back-siphonage.
Shock Treatment Preparation
When preparing multiple wells for shock treatment, it is essential to ensure that each well is isolated from the others to prevent contamination. This can be achieved by shutting off the water supply to each well and installing check valves to prevent back-siphonage. Typically, a minimum of 10-20 gallons of water is required per well for shock treatment.
Chlorination Equipment and Procedure
To shock treat multiple wells simultaneously, a centralized chlorination system is recommended. This system should include a pump, a chlorinator, and a distribution system capable of handling the required water flow rates and chlorine dosages. For example, a system capable of treating 100 gallons per minute (gpm) can accommodate 2-4 wells, depending on the flow rate of each well. The recommended chlorine dosage is 2-5 parts per million (ppm) for 30 minutes to 1 hour, depending on the well’s water quality and the type of chlorine used.
Safety Precautions and Monitoring
During the shock treatment process, it is crucial to monitor the water quality and pH levels to ensure that the chlorine levels do not exceed 5 ppm, which can cause health risks and damage to equipment. Additionally, personnel should wear protective gear, including gloves, masks, and eyewear, to prevent exposure to chlorine fumes and splashes. Regular water quality testing and monitoring should be conducted before, during, and after the shock treatment process to ensure that the water meets or exceeds safe drinking water standards.
