I found some information on the net, apparently our city adds fluoride to water to prevent tooth decay
"Q: What is the hardness of Brandon's drinking water?
A: Hardness is a measure of the amount of minerals, i.e. calcium and magnesium, dissolved in water. The average hardness of water is 150mg per liter."

I use brita filter which claims to reduce Chlorine (up to 99%) Calcium, Magnesium, Lead, and Copper
"Does the BRITA water filter cartridge remove all minerals from drinking water?
The BRITA water filter cartridge only partially removes the hardness from drinking water. This part is temporary hardness, which causes scale deposits during cooking. It does not remove all of the minerals from the water. It reduces the concentration of calcium and magnesium with cation ion exchange resins, but theses substances are not completely removed as in desalination systems or industrial plants that use reverse osmosis or distillation processes, for example."
"Has filtered water any additional advantages (On Tap)?
The BRITA water filter cartridge reduces chlorine and chlorine compounds as well as other undesirable flavours that may be present in tap water. Heavy metals in tap water, such as lead and copper that can be caused by household plumbing pipes, are also reduced. The elimination of lead and copper in tap water is desirable to protect human health. The claim of the BRITA water filter cartridge to reduce copper and lead significantly has been substantiated in numerous tests. Regionally related traces of pesticides in drinking water can also be minimised by the use of the BRITA water filter cartridges. "
I am currently drinking Fiji water, it's the lowest mineral water I know of that I can find.

This site shows a very similar mineral count of Fiji water but is slightly lower
http://www.mineralwaters.org/index.php? ... parval=957. It has additional information such as hardness 132 and TDS of 210 ml/L
