A boil advisory remains in effect for residents and water customers in the Village of Cadiz following continued issues with water quality linked to recent storms and extreme heat.
Village officials issued the advisory after routine testing revealed elevated contaminant levels in the water supply. The disturbance originated at Tappan Lake, the community’s primary water source, where weather-related disruptions caused sludge buildup in municipal water storage tanks.
Crews have taken steps to address the problem, including removing sludge with divers and treating the water with chemicals. However, water quality has not remained within acceptable safety levels for a full 48-hour period, and the advisory will remain in effect until further notice.
Residents are advised to boil tap water for at least one minute before drinking, cooking, or brushing teeth.
To assist those impacted, a self-serve water station is now available at Sally Buffalo Park, located across from the park office. A water transport truck is on site daily from 7 a.m. to 7 p.m. Residents must bring their own containers. The water is free of charge and available to anyone affected by the advisory. Officials are urging residents to share this information with neighbors who may not have internet access.
Community members have also expressed growing concern over the state of the water supply. One resident, Cody Mattern, posted images on social media showing significant sediment collected in household water filters. He urged others not to drink the water, stating that even boiling had not prevented contamination from entering his filtration system.
Village officials have not responded directly to the post but reaffirmed that the advisory remains in place for public safety.
No timeline has been given for when the advisory will be lifted. Residents are encouraged to continue monitoring official updates from the Village of Cadiz and follow all public health guidance.
