U.S. Geological Survey, in cooperation with Miami-Dade County, performed a sequential, aquifer stress test from August 15 to October 12, 2011, on the Floridan aquifer system at the North District Wastewater Treatment Plant, in Miami-Dade County, Florida. Miami-Dade County stressed the Floridan aquifer system with four municipal injection wells at the North District. The U.S. Geological Survey measured pressure with a Level TROLL 700 from August 15, 2011, to October 12, 2011, for injection well IW-1. These data are part of a larger data set that describe the stress test at the North District (King, 2016, http://dx.doi.org/10.5066/F7QZ2819).
