Disinfection Water Wells and Sterilization

Abstract

Disinfection is an important step in ensuring that water is safe to drink. Well disinfection is used to inactivate or control bacteria populations in a well and the distribution system. Disinfection is the inactivation or destruction of pathogenic organisms through the disruption of the organisms' normal life processes. The objective of this work is to clean and/or disinfect entire borehole to prepare wells for pump installation. The last water sample was collected after the well disinfection on that time. The results of water chemical analysis are presented in Tables 2-4, and there was nothing found against the specification requirements. After a reaction time of approximately 12 h, the well was cleaned from the sterilization solution by airlifting until chlorine concentration in the water reached 0 mg/l. Then through analyzing the test for samples of water after disinfection and sterilization the wells showed the Iron Bacteria were not seen and the Bacteria Species/Anaerobic Bacteria were absent.

The Characterization of Groundwater Quality for Safe Drinking Water Wells via Disinfection and Sterilization in Jordan: A Case Study

“…It was confirmed, via the final CCTV survey and bacteriological laboratory results of the collected water samples, that the ongoing processes of biofouling and corrosion in wells may not affect their productivity or safety. The test results for the water samples taken from sterilized and disinfected wells revealed that neither iron bacteria nor bacteria species/anaerobic bacteria were present in the wells [59]. The content of total coliform bacteria after well sterilization was <1.8, which is also above the threshold value (0/100 mL).…”
