Dissolved Solids,, and reporting the weight of the solids remaining after evaporation in milligrams per liter. The TDS concentrations in natural freshwaters typically range from about 20–1,000 mg/L; the solids consist mainly of bicarbonate (and carbonate at pH above 8.3), chloride, sulfate, calcium, magnesium, potas

Particulate Matter, Color, Turbidity, and Light,ginate from erosion on watersheds and within water bodies, vegetative debris from watersheds, and microorganisms produced in water bodies. Suspended particles vary from tiny colloids (1–100 mμ) that remain suspended indefinitely in still water to larger silt and sand particles held in suspension by

pH, Carbon Dioxide, and Alkalinity,s. Because dissolved carbon dioxide is acidic, rainwater that is saturated with this gas is naturally acidic—usually about pH 5.6. Limestone, calcium silicate, and feldspars in soils and other geological formations dissolve through the action of carbon dioxide to increase the concentration of bicarb

Nitrogen, nitrate (NO..) that reaches the earth’s surface in rainfall. Atmospheric nitrogen also can be fixed as organic nitrogen by bacteria and blue-green algae, and it can be reduced to ammonia (NH.) by industrial nitrogen fixation. Plants use ammonium (NH..) or nitrate as nutrients for making protein tha

Phosphorus,turally in most geological formations and soils in varying amounts and forms; the main source of agricultural and industrial phosphate is deposits of the mineral apatite—known as rock phosphate. Municipal and agricultural pollution is a major source of phosphorus to many water bodies. Most dissolved
