After disinfecting a well, what is a recommended immediate step?

• A. Take bacteriological sample
• B. Flush the system
• C. Increase chlorine dose
• D. Ignore results

Answer: (A)

Verifying disinfection success by testing for bacteria is the essential immediate step after treating a well. Taking a bacteriological sample lets you directly check for the presence of coliform bacteria and confirm that the disinfection has effectively rendered the water safe. If the test shows no bacteria, you can proceed with confidence that the water meets safety standards. If bacteria are detected, you know adjustments or повторная treatment are needed and you’ll test again after those steps. While flushing can help clear residual disinfectant and improve sampling conditions, it doesn’t by itself confirm safety. Increasing the chlorine dose is a corrective step based on test results, not the immediate verification. Ignoring results would neglect a critical public health check.
