High total suspended solids usually indicate fertile and producing waters.
Using an analytical balance that weighs to the 0.0001 g is desirable. 3 clean dry 250 ml beakers or evaporating dishes. Slowly and carefully evaporate the water sample to dryness, using a hot plate. Do not let the samples get too hot or some of the dissolved solids may be vaporized or decomposed. When the samples are dry, reweigh the containers and determine the weight of the solids dissolved in 100 ml of water.
