Peralta Well inspection shows fractured bedrock, falling static levels and reduced flows
Summary
A camera inspection of the Peralta Well found evidence of fractured bedrock and sediment, a static level near 218 feet, and a drop in pump output from about 225 GPM to roughly 80 GPM after sustained use; staff said the well is unreliable as a primary source.
Village staff presented camera images and flow data showing the Peralta Well had lost significant available water. Evan said the well is 250 feet deep, the pump is set at 235 feet and the current static level is about 218 feet; he described visible erosion marks and sediment that indicate fractured bedrock and poor recharge.
"The well itself is 250 feet. But our pump sits 235 feet. And currently, the static level now is 220 feet. Well, 218, to be exact," Evan said, explaining that the reduced static head has sharply reduced extraction capacity. He added the measured flow rate dropped from about 225 GPM to roughly 80 GPM and that performance degrades after 12 hours of pumping.
Director Epler noted the well casing lacks a perforated screen typically seen in fully developed municipal wells and said that fractured bedrock likely limits how deep a developer could effectively drill at this site. Staff recommended the village treat Peralta as a backup resource while pursuing a new well site or assessing an artesian well that has been slated for abandonment.
