Some folks may not care to take the time to read it.
Here are some verbatim from the BLM document;
The predicted +2 inches of thickness addition to the salt crust (Bingham, 1991, p. 435) as a result of the Laydown Project was not observed at any of the multi-year monitoring locations upon conclusion of the five-year experiment.
6.2 million tons of sodium chloride as human-made enriched brine was pumped back onto the Bonneville Salt Flats from 1 November through at least 30 April for five consecutive years.

3. During the same time period an estimated 4.2 million tons were removed by the production 3ditches leaving 2 million tons that went directly to the shallow brine aquifer
Salt Laydown: The impacts would be the same as described in the Proposed Action except for the fact that there would be no production monitoring approved and a material balance would not be calculated and the company would not be required to continue if they for business reasons decide it is not in their interest to do so.
Salt Laydown: The Alluvial Fan aquifer would continue to be pumped at the rate of approximately 1.2 billion gallons per year (Intrepid, 2008, p.72) the permit issued by the Utah Division of Water Rights allows Intrepid to pump 8.6 billion gallons per year. Based upon earliest data (Turk, 1969, p.77 ) and the information submitted by Intrepid Wendover in the mining plan in 2008, indicates there has been an increase in salinity in the Alluvial Fill aquifer from 8,200 ppm TDS to over 18,000 ppm (Intrepid, 2008,p.
. Individual wells have not been tracked but, these figures are based on the average of all the wells. The effect of this pumping shows the Alluvial Fan aquifer is interconnected with the Shallow Brine aquifer and the pumping of the Alluvial Fan aquifer is drawing some of the brine from the Shallow Brine aquifer. As the Alluvial Fan aquifer becomes more saline, the company would have an increasingly difficult time using this water for the intended purpose.
AND BINGO! IN BLACK AND WHITE!
Salt Laydown: The water component of the shallow brine aquifer is thought to be recharged from direct precipitation and the minerals recharged from relatively slower processes, as brine is drawn off by potash extraction operation, the mineral concentration of the aquifer is slowly decreasing by the amount of production each year. Therefore by supplementing the mineral recharge only “as site conditions dictate (Intrepid, 2008, p. 94) the proposed action could eventually reduce the concentration of minerals in the shallow brine aquifer north of I-80. This could result in the leaching of more salt from the salt crust into the aquifer and reducing the size and thickness of the crust
