What is the recommended action when turbidity levels are too high?

When turbidity levels are too high, filtering and clarifying the water is the recommended action because it effectively removes suspended particles, sediments, and contaminants that contribute to increased turbidity. This process not only helps in meeting water quality standards but also ensures the safety of the water for consumption. High turbidity can shield pathogens from disinfection processes, making filtration crucial in improving the water's clarity and reducing the risk of waterborne diseases.

While diluting with clean water may temporarily reduce turbidity, it doesn't address the underlying issue of contamination and may lead to a larger volume of water that still requires treatment. Increasing chemical treatment might not efficiently resolve the problem of high turbidity and can lead to excessive chemical use which can have other health implications. Testing for pathogens is important but occurs after turbidity is managed since high turbidity can hinder the effectiveness of pathogen detection methods. Thus, filtration and clarification provide a more direct and effective solution in addressing high turbidity levels.
