Abstract

Lithologic, hydraulic, geophysical, and water-quality data were collected at the Bear Creek subsurface-injection test site at St. Petersburg, FL. The data were collected to determine the feasibility of subsurface injection of storm runoff. An exploratory hole and five observation wells were constructed between October 1974 and April 1976. The lithology of the upper 185 feet at the test site is predominantly sand and marl. From 185 feet to 3,504 feet, limestone and dolomite predominate. Also , gypsum is present below 1.290 feet. Vertical intrinsic permeability, porosity, and compressibility of cores are reported. A 73-hour withdrawal test discharging 3,450 gallons per minute was run in the test injection well. At the site, chloride concentration in water from 192 to 340 feet, ranged from 150 to 680 milligrams per liter, and from 500 to 1,267 feet ranged from 16,000 to 20,000 milligrams per liter. Eleven additional wells near the test site were sampled for water quality. (Woodard-USGS)
