WELD COUNTY — The Weld County Health Department is offering free bacterial well water test kits to residents concerned about possible groundwater contamination.
“While it’s possible groundwater can be affected by flooded surface water contaminated by sewage and other microorganisms due to the flood,” said Trevor Jiricek, Environmental Health Division Director, “the only way to determine contamination is to test the well water.”
In general, wells greater than 100 feet in depth, where the well head was not submerged by floodwaters, should not be impacted. It is recommended that groundwater wells under 100 feet in depth and in close proximity to the flood plain be tested to ensure their potability. Because infiltration of water through various subsurface geological zones is complex and depends on many factors, a single sample analysis may not be adequate to ensure the sustained potability of water.
“Testing is also important because groundwater may be impacted long after the flood waters have receded,” Jiricek said.
In an effort to protect public health, the Weld County Commissioners will continue to offer free bacterial water tests for those residents impacted by flood waters until Jan. 1, 2014. To request a free bacterial water test kit, please contact the Weld County Department of Public Health and Environment, Environmental Health Division at 970-304-6415.
