Quick Answer
After shock treating well water with chlorine, document the chlorine dosage rate, contact time, and pH levels before and after treatment. Record the temperature and turbidity of the water, as well as any notable changes or observations. This information helps ensure the treatment was effective and guides future maintenance.
Pre-Treatment Documentation
When shock treating well water with chlorine, it’s essential to document the pre-treatment conditions. Record the pH level of the water, which should ideally be between 6.5 and 8.5 for effective chlorine disinfection. Measure the turbidity of the water using a turbidity meter, and note any notable changes in color or odor. Take a water sample for laboratory analysis to determine the presence of bacteria, viruses, or other contaminants.
Treatment Parameters
Document the chlorine dosage rate used, which is typically between 1 and 5 milligrams per liter (mg/L) for well water. The recommended contact time for chlorine disinfection is at least 30 minutes at temperatures between 50°F and 70°F (10°C and 21°C). Monitor the pH level of the water during treatment, adjusting as necessary to prevent pH-related issues.
Post-Treatment Documentation
After shock treating the well water, document the post-treatment conditions. Record the pH level of the water, which should ideally be between 6.5 and 8.5. Measure the turbidity of the water again and compare it to the pre-treatment reading. Take another water sample for laboratory analysis to verify the effectiveness of the treatment. Note any changes or observations, including any residual chlorine levels.
