The specific parameters and their acceptable limits vary depending on the designated water quality class. Exceeding the limits for a particular parameter in a water body will result in its classification into a lower class, indicating reduced suitability for its intended uses.
Water Quality Classes and Criteria
The NWQS defines several classes of water quality, each with specific permitted uses and corresponding limits for various parameters. The exact number and designations of classes may vary slightly depending on the specific regulatory document and its revisions, but generally, the classes reflect a decreasing level of water quality. Higher classes indicate cleaner water suitable for more sensitive uses.
For example, Class I waters are pristine and suitable for drinking water sources with minimal treatment, while lower classes may be suitable only for industrial uses or irrigation. The criteria used are based on established scientific standards and guidelines, often referencing international best practices.
Examples of Water Bodies in Each Class
Providing precise examples of Malaysian water bodies belonging to each class requires access to current, publicly available monitoring data which is beyond the scope of this response. However, generally speaking:
Class I waters might include certain pristine rivers and reservoirs in less populated areas, upstream sections of major rivers before significant human impact, or protected areas with minimal pollution. Class II waters might include sections of rivers used for recreation or fisheries, and some lakes with moderate pollution levels. Class III and IV waters might include rivers and streams heavily impacted by industrial or agricultural runoff, potentially suitable only for industrial cooling or irrigation after treatment.
Permitted Uses of Water Based on Classification
The following table summarizes the general permitted uses of water based on its classification. Note that this is a simplified representation, and specific details should be obtained from the official NWQS documents.

Pollutants have devastating effects on aquatic ecosystems and human health. Heavy metal contamination, for example, can bioaccumulate in aquatic organisms, leading to toxicity and disruptions in the food chain. Nutrient pollution from agricultural runoff causes algal blooms, depleting oxygen levels and creating “dead zones” where aquatic life cannot survive. Pathogens from untreated sewage pose a direct threat to human health, causing waterborne diseases like cholera and typhoid.
Plastic pollution harms marine animals through ingestion and entanglement, disrupting biodiversity. Furthermore, contaminated water sources can lead to various health issues in humans, including gastrointestinal problems, skin infections, and long-term health complications from exposure to toxic chemicals.
Relationship Between Pollution Sources and Water Quality Parameters
Specific pollution sources directly affect various water quality parameters. For instance, industrial discharge often elevates levels of heavy metals (e.g., lead, mercury) and dissolved solids, while agricultural runoff increases nutrient concentrations (e.g., nitrates, phosphates) and turbidity. Sewage contamination raises levels of biological oxygen demand (BOD) and fecal coliform bacteria. These changes in water quality parameters directly reflect the type and severity of pollution affecting a particular water body.
Monitoring these parameters is essential for assessing the overall health of aquatic ecosystems and for implementing effective pollution control measures.
Visual Representation of Pollution’s Effects on Water Quality Classes
Imagine a series of four charts, each representing a different water quality class (Class I being the highest quality and Class IV the lowest). Class I would depict a clear, pristine river with diverse aquatic life, abundant vegetation, and low levels of pollutants. As we move towards Class IV, the charts progressively show a decline in water quality.
Class II might display some signs of pollution, such as slight turbidity and reduced aquatic life diversity. Class III would show significant pollution with algal blooms, reduced oxygen levels, and limited aquatic life. Finally, Class IV would represent heavily polluted water, potentially with visible debris, dead zones, and a complete lack of aquatic life. This visual progression highlights the direct correlation between pollution levels and the degradation of water quality across different classes.
