Document Summary
Physical water quality parameters are water properties that respond to the senses of sight, touch, taste, and smell. Suspended solids, turbidity, color, taste, odor, and temperature are examples of these characteristics. Suspended solids are typically made up of inorganic and/or organic particles. This category also includes fine dispersion of immiscible liquids such as oils and waxes. Fine silica, clay, silt, and other soil components could be inorganic solids. Organic matter is typically derived from plants and animals, as well as synthetic organic materials. Because of the soil"s filtering ability, ground water is normally free of suspended solids. Domestic and industrial water use generates a wide range of suspended matter, both organic and inorganic in nature. Suspended matter is undesirable because it detracts from the appearance and is aesthetically unpleasant. Furthermore, organic suspended matter is biologically degraded, resulting in objectionable by-products. Disease-causing organisms, as well as organisms such as toxin-producing algae strains, can be found in biologically active (live) suspended solids.
