Key Concepts

Screening

A preliminary analysis to assess whether the water is good or bad without extensive testing.

Total Dissolved Solids (TDS)

The measure of all organic and inorganic substances dissolved in water, important for evaluating water quality.

Total Suspended Solids (TSS)

The measure of all particles that are suspended in water and do not dissolve, impacting water clarity and safety.

Hydrophobicity

A property of substances that do not interact well with water and hence have lower solubility.
