Fresh Water Research – Week Two

In the StarTribune article,”Minnesota draining its supplies of water,” Josephine Marcotty elaborates how water sources in Minnesota are being depleted. The water comes from the source, and is either used up on crop fields or sent down drains or washed down drains. Not uncommonly, the drained water is treated and sent down the Mississippi River. Because this is done often, the recharging of the supply of water in Minnesota cannot meet the current demands. Water comes from surface water or groundwater aquifers which are coming to be depleted. All that would remain would be surface water. This depends on how much rain and snow there is, which isn’t as reliable; precipitation may be to strong to seep into the water table, or there could be too light of rain. Soon, farmers and businesses would need to share ground water or leave the state just so water can be saved. Otherwise, farmers could use irrigation which is more efficient for yield of crops. Another option for getting water would be to get water from an aquifer that sends water through a pipeline for several miles to get to its destination, but is several times more expensive. One may think of recycling and treating used water rather than treating and sending water down the Mississippi river, but this idea is controversial.

As I posted previously, I posed the question: how can the depletion of water sources be prevented? In the StarTribune article,”Minnesota draining its supplies of water,” Josephine Marcotty answers,”state regulators…are planning to experiment with more stringent rules that will require some local communities to allocate scarce water.” Water supply will soon be so low that smaller communities in Minnesota will need to start contributing to rationing by enforcing water conservations. Having local towns of the metro area enforcing their own conservations would be more effective than the state government doing so alone.
