Have you noticed a change in your Kalamazoo City water in the past year?  We certainly have.  

According to Wikipedia,

Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates.

Hard drinking water may have moderate health benefits, but can pose serious problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of suds formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters.[1] Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects.

If I understand that correctly, we shouldn't have to worry about any health concerns by drinking hard water.  That is a relief.  However, here are a few things to look out for.

Looks like I have a water softener purchase in my near future.
