21. Water purity greater than 100 p . p . m . of total dissolved solids is often quoted as ideal. 22. In many cases, conductivity is linked directly to the total dissolved solids ( T . D . S . ). 23. The minimum concentration of total dissolved solids is 34 parts per million and the maximum concentration is 86 parts per million. 24. Basin models are used to more comprehensively evaluate total dissolved solids within a catchment basin and dynamically along various stream reaches. 25. "' Total dissolved solids ( TDS ) "'is a measure of the combined content of all colloidal sol ) suspended form. 26. As a consequence, as nitrate forms a component of total dissolved solids , they are widely used as an indicator of water quality. 27. For hydroponic uses, total dissolved solids is considered one of the best indices of nutrient availability for the aquatic plants being grown. 28. The water contains a high mineral content, as measured by Total Dissolved Solids ( TDS ) of 2, 400 milligrams per liter. 29. Less than 2 milligrams per liter of suspended solids were observed, but 66 milligrams per liter of total dissolved solids were recorded. 30. The concentration of total dissolved solids ranged from 50.00 to 490.00 milligrams per liter, with an average of 167.81 milligrams per liter.
