Water Testing

Water Solutions offers the following water tests for free.

Total Dissolved Solids

A Total Dissolved Solids test is commonly called a TDS test which determines the dissolved solids that are in your water. This is needed to determine the performance of your Reverse Osmosis Membrane, which is the intregal part of your reverse osmsosis drinking water system. For example, Calgary TDS varies between 140-180 ppm. Typically good performing home RO membranes remove between 92-98% of all dissolved solids. Thus 160 TDS X 95% removal (1 – 0.95 = 0.05) = 8 ppm TDS.


Hard water is water that has high mineral content (in contrast with soft water). Hardness tests measure the total amount of calcium and magnesium in the water measured in ppm or gpg. Calgary hardness varies from 14-16 gpg. This is considered very hard water.


When the iron level in water exceeds the 0.3 mg/l limit, we experience red, brown, or yellow staining of laundry, glassware, dishes, and household fixtures such as bathtubs and sinks. The water may also have a metallic taste and an offensive odor. High iron levels can cause water system piping and fixtures to become restricted or clogged. Iron tests determine the type iron filter needed to rid you of staining and/or smell.


Chlorine test is used to determine the total amount of free chlorine in water. We normally provide these tests to determine the effectiveness of Carbon filters.


PH indicates the acidity or alkalinity, or basic, is known as the pH value. A pH value of 7 means a substance is neutral. The lower value indicates acidity, and a higher value is a sign of alkalinity.
