|Typical Injection Well --- NOT 2 MILES|
Water and Sewer Department says they are exploring the geology to find out if any formation below the Boulder Zone is better for injection of treated effluent. Hmm. I don't believe that for a minute (unless of course they already know it will leak at shallower levels).
Here is my theory, remember an energy company did the one in Tampa. I think this very deep well is being dug with our tax dollars for the benefit of gathering data for Florida Power and Light's Nuke Plant's injection wells. Or maybe worse: Fracking Crap.
I originally saw the drill rig in July at Virginia Key.
After they dig the deepest well in Florida and data is collected the well will be plugged. The injection well they will use goes to about 3,000 below the land surface and they will be injecting a mix of secondary treated effluent, leachate from the landfill and process water. That would be into the boulder zone.
How safe is injecting waste underground (there are 680,000 injection wells nationwide):
"In interviews, several key experts acknowledged that the idea that injection is safe rests on science that has not kept pace with reality, and on oversight that doesn’t always work.
“In 10 to 100 years we are going to find out that most of our groundwater is polluted,” said Mario Salazar, an engineer who worked for 25 years as a technical expert with the EPA’s underground injection program in Washington. “A lot of people are going to get sick, and a lot of people may die.”
There is also Fracturing Threats: see The Pitfalls of Florida's Karst Geology and industrial scale application of aquifer storage and recovery wells. Last but not least we get those pesky earthquakes.

After five years of construction, the $120 million Polk Power Station Regional Reclaimed Water Partnership Initiative officially entered into service in March. The project will allow Tampa Electric to collect reclaimed water from the city of Lakeland, treat it and use it for cooling water at the Polk Power Station.
“This public-private partnership is on the leading edge of innovative water use,” said Gordon Gillette, president of Tampa Electric. “It has far-reaching water-resource benefits that will be seen in Tampa Bay for multiple generations.”
The project includes a reclaimed-water pumping station and 15-mile pipeline between the city of Lakeland's wetland treatment system, east of Mulberry, and Tampa Electric's Polk Power Station. The project also includes a water-treatment system and two deep-injection wells – more than 1.5 miles underground – on Polk Power Station property.
This project will:
Minimize any future withdrawals of groundwater to cool Polk Power Station.
Clean up Tampa Bay by diverting treated wastewater previously discharged by the city of Lakeland. This will remove nitrogen from the water of Hillsborough and Tampa bays, which will help improve the sea grasses and populations of small fish, crabs and oysters.
Give the city of Lakeland greater capacity to use additional groundwater for drinking as the city grows.
Because of the combination of environmental benefits, the Southwest Florida Water Management District (SWFWMD) agreed to partially fund the project by investing about $45 million.
For many years, Lakeland discharged its excess wastewater into the Alafia River, which feeds into Tampa Bay. Through a 30-year agreement, Lakeland will instead provide about 5 million gallons per day of reclaimed water to the Polk Power Station, with the ability to expand to 17 million gallons a day. Water will be provided from Lakeland at no cost for at least the first 20 years.
