Dissolved and suspended solids analyses are routinely tested for water andor wastewater to assess its quality. The following description is for typical dissolved and suspended solids analyses. A mL water sample has been evaporated until dry in a crucible drying dish. The dry tare weight of the dish was g After being placed in an oven at deg C for one hour, the crucible was placed is a desiccator to cool. After cooling, the weight of the residue plus the dish was found to be g For the same water, a mL sample has been filtered through a glass fiber filter. The dry tare weight of the filter plus aluminum drying pan in which the filter paper is placed was g After filtration, the filter paper is placed in a different oven at deg C for one hour. After being cooled and desiccated, the weight of the residue, filter paper, and drying dish if found to g Determine the total dissolved and suspended solids concentration in the water, and speculate as to whether this water is a surface water or ground water.
