Mineral content can often affect the taste of the water and many
people can detect a salty taste when TDS is above 500 parts per
High TDS levels are also responsible for water spotting on dishes
and plumbing fixtures and for the white mineral buildup sometimes
seen on water faucets and swamp coolers.
In taste tests, Tucson Water customers preferred a blend of water
with TDS (total dissolved solids) in the range of 350 - 450 parts
per million. Although there are no health-related water quality
standards for TDS in water, Tucson Was has committed to this range
as a maximum for TDS in the blend being delivered from Clearwater.
The amount of TDS in the blend will not exceed 450 parts per million
for the foreseeable future.
