Although, prior to treatment the water has high levels of TCE, a cancer causing solvent, after treatment the level of TCE is undetectable. Even though this water exceeds safety standards it can no longer be used because it is chemically treated water. Now, water can only come from uncontaminated wells in the Tucson area. Water may be sufficient now, but in time there may not be enough water to go around from these wells alone. One of the many questions to ask yourself is what is wrong with chemically treated water.
Most people are just scared of the word chemical.
If CAP water is held to these same standards there will be no problem with chemically treated water. The only reason people are scared of chemically treated water is because when CAP water was delivered, it was rusty and smelly. There is nothing wrong with chemically treated water if it is done properly. Due to Proposition 200 there are some other plans for the chemically treated water. The first plan is to recharge the aquifers.
