By combining filtration with another treatment method, such as disinfection, a more comprehensive approach can be achieved. In this case, the correct answer is that when used in conjunction with filtration, a specific method (not mentioned in the question to avoid bias) is effective for treating well water. This highlights the importance of utilizing multiple methods to ensure safe and clean water from well systems.
