2. DIFFERENT WATER QUALITY STANDARDS

3. Importance of Water Quality Standards Water is essential in our daily life For cooking, cleaning, and many other activities For drinking purposes ( more important) Identifies the lakes and rivers that can be restored and protected and finds out how we set limits for them Conclusion: The standards ensure our health and environment

4. What are water quality standards? Water quality standards are established limits for various physical, chemical, and biological parameters present in water. These standards are set to protect public health, aquatic life, and the environment. They are crucial for ensuring safe drinking water, maintaining healthy ecosystems, and supporting various water uses.

5. Why are different standards needed? Water has  diverse uses , each with  specific quality requirements . For example,  drinking water  needs to meet stricter standards than  agricultural irrigation water . Different standards are essential to ensure the  suitability of water  for its intended use and  minimize potential risks  associated with waterborne diseases or environmental damage.

6. Examples of different water quality standards Drinking water:   Stringent standards for  microbial safety, chemical contaminants, and aesthetic qualities  like taste and odor. Recreational water:   Standards for  microbial safety  to protect users from waterborne illnesses. Irrigation water:   Standards for  salinity, specific chemicals, and pH  to prevent adverse effects on soil and crops. Industrial water:   Standards vary depending on the  specific industry  and its water quality needs.

7. Key Parameters in Water Quality Standards Different water uses have varying priorities for specific parameters. Some common parameters include: pH  Acidity or alkalinity of water. Turbidity:  Cloudiness of water. Dissolved oxygen:  Amount of oxygen available for aquatic life. Salinity  Amount of dissolved salts in water. Total coliform bacteria:  Indicator of fecal contamination and potential health risks.

8. Global Water Quality Standards 1 . World Health Organization (WHO) Guidelines 2 . European Union Water Framework Directive 3 . United States Environmental Protection Agency (EPA) Standards

9. WHO Guidelines Safe Drinking Water Guidelines Key Parameters: Microorganisms, Chemicals, Radiologicals Recommended Maximum Concentrations

10. European Union Water Framework Directive Focus on Water Management and Protection Ecological and Chemical Status Environmental Quality Standards (EQS)

11. EPA Standards Safe Drinking Water Act National Ambient Water Quality Standards (NAAQS) Primary and Secondary Standards

12. Importance of Consistent Standards Cross-border Water Quality Management Harmonization of Standards International Collaboration

13. Challenges in Implementing Standards Monitoring and Enforcement Adequate Infrastructure Addressing Emerging Contaminants

14. BENEFITS OF WATER QUALITY STANDARDS Water quality standards help to protect public health. They can reduce the risk of waterborne diseases, such as cholera, typhoid, and dysentery. Water quality standards also help to protect the environment. They can help to improve the quality of our rivers, lakes, and oceans, which provide habitat for fish and other aquatic life.

15. Conclusion Water quality standards are essential for safeguarding our health and the environment. By establishing limits on pollutants and outlining desired water conditions, they ensure the safety of our drinking water and the well-being of aquatic ecosystems. Upholding these standards involves collaboration between government agencies, public water systems, and individuals. Through continued monitoring, enforcement, and responsible water usage practices, we can collectively ensure that future generations inherit clean and healthy water resources.
