Why is it important to test stream water before providing it to horses?

Testing stream water before providing it to horses is crucial to ensure that it is safe for consumption. Contamination or the presence of toxins can lead to serious health issues in horses, including gastrointestinal disturbances, poisoning, or other detrimental effects. Water sources can be contaminated by agricultural runoff, pollutants, or harmful microorganisms, which can all pose risks to animal health.

Ensuring that water is free from contaminants allows for better management of the horses' overall well-being, helping to prevent illness and maintain hydration and proper health. Regular testing can identify potential hazards early, allowing for timely intervention and the proper handling of the water source. While determining taste, cleanliness, and plant life can provide additional information, the priority in testing should always be the safety and health of the horses consuming the water.
