This is when a known value in a solution is
added to the sample being tested as a check on previous test results.
A standard solution is a known concentration
of an element in water.
Standard Solutions may be furnished as part
of a kit or made up prior to the test.

Untreated Water Sample:
The term Untreated Water or Original
Water Sample appearing in some procedures indicates that the raw
water is to be used without the addition of chemicals.
