Water Treatment Class E Practice Test 2026 – Complete Exam Prep

Disinfecting a newly completed well is primarily designed to eliminate harmful bacteria that could pose health risks to those consuming the water. When a well is drilled, it is exposed to potential contaminants from the surrounding environment, including bacteria, viruses, and pathogens. These microorganisms can enter the water supply during the construction process or from nearby sources.

By applying disinfection methods, commonly using chlorine or other disinfectants, the goal is to ensure that any harmful bacteria present are effectively killed off. This is a critical step in safeguarding public health, as consuming contaminated water can lead to serious illnesses.

While improving water taste, stabilizing pH levels, and reducing total dissolved solids are important aspects of water quality, they are not the primary reasons for disinfecting a newly completed well. Disinfection is specifically focused on ensuring the microbiological safety of the water supply.
