Show answer & explanation
Correct answer: A
Statement I is correct because total solids are defined as the residue remaining after a water sample has been evaporated. Statement II is also correct because in standard wastewater analysis, dissolved solids are typically defined as material passing through a filter (e.g., 0.45 μm), which includes colloidal particles that are not captured as suspended solids. Therefore, both statements are accurate.
