Cloudiness in drinking water is attributed to something called turbidity. Turbidity or cloudiness doesn’t necessarily mean drinking water is unsafe. However, 10 of 14 studies reviewed by Drexel University concluded that cloudiness is often an indicator of higher levels of micro-organisms present in the water. Not all cloudiness can be attributed to these. Some turbidity can be attributed to scale build up in pipes or the presence of silt. All things considered there is no direct correlation between cloudiness of drinking water and the safety of drinking this water.

Key Takeaways:

• While researchers have linked cloud tap water to certain illnesses, the link is not straightforward or obvious
• Clear water is not is not a certain indicator that the water is “bug-free”
• Cloudy water does not always mean that harmful microorganisms are present, but can be a by product of the processing

“Overall, the authors of the study concluded that cloudiness alone can’t be used as an indicator for predicting endemic gastrointestinal illnesses.”
