Sand Mines and the Toxins They Produce in Local Water

Toxic residual acrylamides will result from the flocculation procedures that are part of processing of sand. This may contaminate all water that leaves the sand mine processing plant. We don't know where the millions of gallons of processing water Unimin plans to use will go.  Is it down into the ground or will it be piped somewhere?  Obviously the residual acrylamides should be monitored in the surface and soil water after Unimin processes it.

Unimin and Tomah Water: Chemicals? Drought? What's the Impact?

Dear Mayor and city council members,
I would love to call you all personally and discuss this, but with the meeting being tonight, I wanted to make sure you all considered different aspects of supplying Unimin with water besides the financial aspect of it.
I was read the letter you all received from the city administrator that explained all the wonderful financial benefits the City of Tomah would receive by supplying Unimin with their water supply.  That is the good aspects of voting yes tonight.  I am asking you to vote no.
I understand the vote tonight is to change the ordinance so further discussions can be make with Unimin on a developers agreement.  Please vote no.  My reasons are as follows:
1. First and foremost, Unimin told the town of Greenfield that they would be using 70 gallons per minute for their processing of sand.  Now they are saying they will need 1000 gallons per minute.  Their explanation during last night's town hall meeting was that they didn't have the information from their sub contracting company that they have now.  This made no sense to many people in the audience.  Unimin claims to be number on in their field and have been doing business well over 100 years.  How could they have a margin of error from 70 gallons per minute (which did not require them to get a high capacity well) to now 1000 gallons per minute?  With them being so incorrect here, are they incorrect in asking for 1 million per day as well? 
2. Has Unimin told the city what chemicals are used in the processing of sand?  And what happens to this water (and chemicals) once the sand is processed?  It goes back into the ground water.  It's "recycled."  So what happens with these chemical that are being used? 

3. What if there is a drought?  Will Unimin stop the processing of sand during those times?
4.  WHY DOES UNIMIN NOW NEED TOMAH'S WATER SUPPLY???  What has changed?  They told us last night that Greenfield has enough water to supply them.  So why do they need Tomah's?  Have they answered this question?  From my understanding at last night's meeting they expected a layer of shale that the aquifer sits below for them to drill their well into.  They admitted that when they drilled, this layer of shale was not there which surprised them.  I am no geologist, but my impression is that they don't know what will happen if they use 1 million gallons of water per day from Greenfield.  Since there is not the level of shale under this sand supporting the aquifer, what will happen to the homes and land near these wells?  Will it sink?  Is this why the want other water sources?  I suggest that Tomah hire a geologist to study this before they vote yes to the changing or the ordinance.
One thing I have learned from Unimin is that you have to take all of their responses with a grain of salt.  They have some wonderful and smart people working for their company who are good at telling people what they want to hear.   Hire a geologist to study this and educate you all before you vote!
There is no reason for Tomah to rush into changing this ordinance. These council people need to be cautious and educate themselves on every part of what a sand mine will do and not just the wonderful financial aspects of it! I'm not saying Tomah should not allow this eventually, but please, be responsible and educate yourselves first.  Unimin needs this water.  Voting No today does not mean it can't be voted on at a later time.  Please be responsible and get educated before you blindly give the popular and expected vote.  Let's understand the real reasons WHY Unimin now needs to tap into the City of Tomah's water supply first.  And don't go off what Unimin tells you.  Let's find out from a licenced geologist that is not being paid by Unimin.

Top Ten Concerns About Unimin Buying Tomah Water

Dear Mr. Mayor and distiguished members of the city council,

I'm writing you to request that you create a committee to study  Unimin's request that the city of Tomah sell water to Unimin. The committee should weigh the benefits of such an agreement against the possible costs. 

Here are a few questions.

1. Last summer Unimin stressed that they would not need a high capacity well, and said that they would need about 60 gallons per minute, which is less than 100,000 gallons a day. This means that six months out they are asking for ten times the amount of water that they said they would need in July. That's a huge difference.They said they would recycle the water and would need water only to replace that which evaporated. Now they want ten times that. Next summer, what will they want? Ten million gallons a day? The city of Tomah currently uses 1.3 million gallons per day. Six months after moving to the area, Unimin wants almost as much water as the city now consumes.

2. What does Unimin need this much water for? One representative of the DNR I talked to was quite surprised at this volume. It is very high. When they are done with the water, where will it go? Will there be contaminants in it? Keep in mind that Unimin does what it wants and then asks permission--just look at this story about the noncompliance letter  the DNR sent it for starting construction without the required air permit. 

3. A  big water booster pumping station just beyond Toro on the southeast side of the city had to be abandoned six or seven years ago because of benzene. Digging wells give contaminants like that new routes. There is always a risk of contamination when you dig a well--is digging a well to sell water to a business outside the city worth it?

4. What will this mean for city residents? Will this deplete the city's water? How long does Unimin want this much water?

5. You'll be drilling into a water supply that supplies not just the city of Tomah but surrounding communities. Will this deplete the water supply of eastern Monroe County--residential areas, farms, cranberry growers, lakes, fishing streams? What if there is a water shortage and water has to be rationed? Who has priority? The people? Or Unimin? 

6. Where will city residents get their drinking water if their water becomes contaminated?

7. What are the city ordinances governing sending city water to a commercial entity? 

9. Town and Country Engineering has reassured you that 365 million gallons of water a year will have no impact on the city's water supply. How far out have they looked? Have they looked at its impact on neighboring communities?  Apparently, they said that Tomah sits above a massive lake. According to the folks I talked to at the DNR, this is not the case. Tomah sits atop a sponge of consolidated sandstone and a lot of loose sand. Then, you hit granite and you hit it fast. This requires further study. Will Town and Country bid on the Unimin project? Do they do similar work for other entities? Are they looking five years down the road? Thirty? Under what circumstances could water run out?

10. Mayor Rusch, I very much appreciate the time you spent with me on the phone yesterday. You talked of the benefits of a $100 million mine to the tax base. But what is a good tax base worth if it costs you the water that you drink and the air that you breathe? Remember, the city of Tomah is downwind of this mine. Remember, silica dust, which is too fine to see and travels great distances, causes silicosis, which is ultimately fatal. 

Thanks very much for your time!
