Injection Wells

In Idaho, excess stormwater, agricultural water, and facility heating/cooling water are the most common fluids disposed of with injection wells of various design, including standard cased well, drain fields, infiltration trenches. The Underground Injection Control (UIC) program was delegated by EPA to the Idaho Department of Water Resources (IDWR) in 1985. The Idaho Department of Water Resources (IDWR) regulates the construction, operation, and abandonment of all injection wells through the Idaho Underground Injection Control Program. A majority of the wells currently managed by the IDWR UIC program are storm water, agricultural return flow, and heat exchange systems. Wells in this layer are classified as Deep Injection Wells (depth greater than 18 feet) and Shallow Injection Wells (depth less than or equal to 18 feet).
