Dissolved and suspended solids analyses are routinely tested for water and/or wastewater to assess its quality. The following description is for typical dissolved and suspended solids analyses. A 50-mL water sample has been evaporated until dry in a crucible (drying) dish. The dry (tare) weight of the dish was 43.3420 g. After being placed in an oven at 180\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 43.3584 g. For the same water, a 500-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 1.0482 g. After filtration, the filter paper is placed in a different oven at 103\deg C for one hour. After being cooled and desiccated, the weight of the residue, filter paper, and drying dish if found to 1.0604 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.
