What is the optimal amount of total dissolved solids in water for most aquatic plants and animals?
1. A constant level of minerals in the water is necessary for aquatic life. Changes in the amounts of dissolved solids can be harmful because the density of total dissolved solids determines the flow of water in and out of an organism s cells. Concentration of total dissolved solids that are too high or too low may limit the growth and may lead to the death of many aquatic organisms. 2. Drinking water may have a TDS reading of 25-250 mg/L. Drinking water should not exceed 500 mg/L TDS. 3. Distilled water will have a TDS reading that will range from 0.5-1.5 mg/L. 4. The amount of TDS ranges from 100-20,000 mg/L in rivers and may be higher in groundwater. 5. Seawater may contain 35,00 mg/L of TDS. 6. Lakes and streams may have a TDS reading of 50-250 mg/L. What factors are affected by your amount of total dissolved solids in your watershed? 1. A constant level of minerals in the water is necessary for aquatic life.
