Test Description

Acidity

Water’s quantitative ability to react with bases. Influences reaction rates & promotes corrosiveness; influences biological activity and chemical specification. Useful as a measurement for quality of water.

Alkalinity

Water’s capability of neutralizing acids.

Conductivity

The ability of an aqueous solution to conduct an electrical current based on the presence of ions.

Hardness

The sum of calcium and magnesium concentrations.

pH

One of the most important and frequently used measurements in water quality. Used in alkalinity measurements, pH is the measure of H+ ions present. Alkalinity and acidity are the acid-base equilibria. The intensity of the acid or base is indicated by the pH.

TDS

Total Dissolved Solids (TDS) in water. Water with high TDS may induce unfavorable physiological reactions in consumers. Unsatisfactory bathing conditions result with high TDS.

Turbidity

Measure of water clarity. Caused by suspend matter (such as: clay, silt, and organic matter).
