We understand the concerns surrounding microplastics in bottled water and persistent chemicals in tap water, which may prompt the search for healthier hydration options. Water purists believe they have found the answer in "raw water".

But what exactly is raw water? Fundamentally, raw water refers to water that is untreated and unsterilized, often sourced directly from springs.

While various companies now market raw water to consumers, some individuals prefer to drink directly from natural water sources, sharing their experiences on social media.

Despite claims by raw water enthusiasts about its health benefits, medical professionals offer a different perspective. It is essential to understand why consuming raw water can pose risks to your health.

What Is Raw Water?

Raw water is typically defined as unfiltered, unprocessed, or untreated water that is bottled directly from natural springs. The Centers for Disease Control and Prevention (CDC) acknowledges raw water consumption as an "emerging trend."

Various companies, such as Alive Water and Tourmaline Spring, have emerged in the market selling raw water. Experts like Jamie Alan, PhD, suggest that the appeal of raw water may lie in obtaining ingredients as close to their natural source as possible. Recent research indicating the presence of contaminants in common water sources like tap and bottled water may also be driving individuals to seek alternative options, notes Thomas Russo, MD.

What Can Happen If You Drink Raw Water?

Despite claims that raw water is superior to tap water, medical experts caution against its consumption.

An outbreak report by the CDC highlighted an instance of campylobacteriosis linked to raw water consumption, resulting in symptoms like blood-filled diarrhea, stomach pain, fever, and vomiting in affected individuals. This incident involved 19 people falling ill after consuming water from a creek in Montana.

Apart from campylobacteriosis, the risk of contamination is a significant concern associated with raw water. Dr. Alan emphasizes the possibility of upstream pollution, such as through animal feces, leading to the presence of harmful bacteria in the water source. Parasites like giardia, causing digestive issues, can also contaminate raw water.

Additionally, diseases like leptospirosis and shiga toxin-producing can be contracted from untreated water sources due to animal waste contamination.

In summary, consuming raw water can expose individuals to a range of bacterial and parasitic infections, positing significant health risks.

Should We All be Drinking Raw Water?

Medical experts unanimously advise against drinking raw water. Dr. Adalja emphasizes the historical significance of water sanitation in reducing infectious diseases and highlights its civilizing impact. Dr. Alan echoes this sentiment, warning that consuming raw water can disrupt daily life, necessitating medical attention and potentially hospitalization.

Is the "raw" water trend a "healing tonic" or health hazard?
