Water quality in Ayacucho, Peru, is generally poor and unsafe for drinking due to contamination, with many residents having limited access to clean water, leading to illnesses like stomach infections, so visitors must use  bottled or filtered water for drinking, brushing teeth, or washing produce. While Peru has national initiatives, Ayacucho, being one of the poorest regions, struggles significantly with water infrastructure, impacting both urban and rural areas where contamination from pollution or mining is a major issue.
