    Study Notes

    Water Quality Parameters in Hydrology

    • Temperature of surface waters affects biological species and chemical reactions
    • Shallow bodies of water are more affected by ambient temperature
    • Dissipation of waste heat in industry may cause dramatic temperature changes in receiving streams
    • Lower temperature slows biological activity, while a 10°C increase doubles activity if nutrients are present
    • Elevated temperatures favor efficient food-utilizing organisms and algae growth
    • Fish and dissolved oxygen levels are affected by temperature changes
    • Electrical conductivity measures a sample's ability to carry electrical currents
    • High conductivity indicates high contaminant levels, while potable water has low conductivity
    • pH measures hydrogen ion concentration and affects water safety and taste
    • pH levels outside the safe range affect aquatic life and the solubility of heavy metals
    • Acidity in water is due to carbon dioxide and mineral acids, influencing corrosion and biological activities
    • Alkalinity in water neutralizes acids, originates from mineral substances, and affects water taste and pipes

    Water Quality Parameters Summary

    • Sources of suspended solids include inorganic material (clay, silt), organic material (plant fibers, algal cells), and human water use (domestic and industrial).
    • Impacts of suspended solids include aesthetic displeasure and adsorption sites for chemical and biological agents.
    • Measurement of total solids, total suspended solids, and dissolved solids is essential for water quality assessment.
    • Filterable and nonfilterable residues, fixed solids, and volatile solids are important parameters for water analysis.
    • Turbidity measures light absorption or scattering due to suspended material in water.
    • Turbidity sources include clay, silt, organic material, and erosion of colloidal material.
    • High turbidity can interfere with light penetration and photosynthetic reactions in streams and lakes.
    • Groundwater typically has low turbidity due to natural filtration through soil.
    • Water color can be affected by dissolved and suspended components from natural and industrial sources.
    • Color impacts include aesthetic unacceptability and the production of objectionable taste and odor with chlorine.
    • Taste and odor in water can be caused by minerals, metals, salts, and organic substances.
    • Taste and odor can be measured using gas or liquid chromatography and human senses (Threshold Odor Number or TON).
