Jwc Controversy Presentation 2

Water is a very sensitive topic in my community recently. There are issues about water which are polarizing citizens of Crystal, Golden Valley, & New Hope

So, how can water be polarizing? H 2 O

So, what does this have to do with technology? ,[object Object]

The new water treatment systems will include reverse-osmosis technology , which works by pushing low-pressure water through a fine membrane with extremely small openings. ,[object Object],[object Object],[object Object],[object Object]

Because an initial study by the JWC showed the communities “…should consider ‘going it alone’ if Minneapolis rates increased significantly., the JWC authorized a preliminary Water System Feasibility Study which indicated that an independent water system would be both technically and economically feasible.”

What comprises this proposed independent water supply and treatment system? ,[object Object],[object Object],[object Object],[object Object],[object Object]

Point: Counterpoint: To which water engineer for Crystal responded: “… the process used would be the tried and true … chlorine and a number of other chemicals in smaller quantities. The resulting … sludge is caustic but pose no danger to humans unless you choose to take a bath in it. The chlorine comes in … one-ton cylinders. These things have been dropped from airplanes onto dirt (as a test) and have survived the impact. State and federal law requires the facility to be able to neutralize the entire one ton if it were to escape into the containment building they are required to be housed in on site.” From the Duluth Ch. Of Commerce: “ The sewer plant stinks…it would take a half billion dollars to move it. The intake plant is approximately 15 miles up the north shore. Some days [the smell] is better than others.We also have two other businesses that add to the smell.” One citizen’s concern is about the chemicals… The same person expressed concern is about the smells…

Point: Counterpoint: Lime is used for softening, not filtering. Besides, independent engineering studies have recommended membrane, not lime softening. The membrane technology (reverse osmosis) will also take care of the filtering requirements: ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Another citizen is concerned about cost : Another as concerned that the filtering was not “state-of-the-art”

Point: Counterpoint: Again, the Crystal water engineer responded : “ The amount of water [the JWC] would withdraw COMBINED with … existing municipal wells … in western Hennepin County represents only 7% of the water presently flowing through the aquifer …if you were to dig down [about] 25 feet … you would have a flowing artesian well. That is how much water is in this 200' thick formation of which the top is 300' below the surface.” There are concerns if there will be enough water from the wells And there are concerns about politics…
