The maximum safe permissible limit of chlorides in domestic water supp...
The maximum safe permissible limit of chlorides in domestic water supplies varies depending on the guidelines and regulations in place in a particular region. In general, the maximum allowable concentration of chlorides in drinking water is set to protect against adverse effects on the taste and odor of the water, as well as to ensure the safety of the water for human consumption.
In the United States, the maximum contaminant level (MCL) for chlorides in drinking water is set at 250 mg/L by the Environmental Protection Agency (EPA). This MCL is based on the taste and odor of the water, and is intended to protect against water that tastes and smells too salty.
In the European Union, the maximum permissible limit for chlorides in drinking water is set at 200 mg/L by the European Union Council Directive 98/83/EC. This limit is based on the total dissolved solids (TDS) of the water, and is intended to protect against water that tastes and smells too salty or bitter.
In general, it is not correct to say that the maximum safe permissible limit of chlorides in domestic water supplies is 0.5 mg/L, 2.5 mg/L, or 100 mg/L. These values are lower than the generally accepted limits for chlorides in drinking water, and may not be sufficient to protect against adverse effects on the taste and odor of the water.

**Explanation:**
The maximum safe permissible limit of chlorides in domestic water supplies is 250 mg/l (milligrams per liter). This limit is set to ensure the water is safe for consumption and does not pose any health risks to individuals who use it.
Chlorides are a type of salt compound that can be found in water sources. While some level of chlorides is acceptable, high levels can have negative effects on human health and the environment. Therefore, it is important to establish a maximum limit to prevent these adverse effects.
**Reasons for the Maximum Limit:**
1. **Taste and Odor**: Water with high chloride content can have a salty taste and odor, making it unpleasant to drink. The maximum limit helps to ensure that the water remains palatable and enjoyable for consumption.
2. **Corrosion**: Chlorides can contribute to corrosion in pipes and plumbing fixtures. High chloride levels in water can corrode metal pipes, leading to leaks and potentially contaminating the water supply. By setting a maximum limit, the risk of corrosion and associated problems can be minimized.
3. **Health Concerns**: Excessive chloride intake can have adverse health effects, especially for individuals with certain medical conditions. High chloride levels in water can contribute to hypertension, electrolyte imbalance, and kidney problems. The maximum limit ensures that the water is safe for consumption and does not pose any health risks.
4. **Environmental Impact**: Discharging water with high chloride levels into the environment can harm aquatic ecosystems. Chlorides can be toxic to aquatic life, especially in freshwater habitats. By setting a maximum limit, the potential negative impact on the environment can be reduced.
**Conclusion:**
In conclusion, the maximum safe permissible limit of chlorides in domestic water supplies is 250 mg/l. This limit is established to ensure the water remains safe for consumption, does not pose any health risks, and minimizes the potential negative impact on the environment. It is essential to monitor and maintain chloride levels in water to ensure the safety and well-being of individuals who use it.
