Chennai’s water quality problems are due to many natural and human causes. Many borewells create groundwater with high levels of total dissolved solids (TDS), making it difficult to drink and unfit for human consumption in many areas.
Causes Behind Chennai’s Water Quality Challenges
The major issues with the quality of water in Chennai stem from the growth of the city and the increasing environmental pressures it has created.
One issue is the overuse of groundwater. In many cases, the household and industrial withdrawal of water has drained them and contaminated those aquifers since the natural supply of freshwater was so limited.
The urban expansion of Chennai has also put pressure on the existing infrastructure. As a result of that growth, there has not been enough capacity for either a water supply, wastewater treatment plants, or a sewer system, all of which contribute to the increased risk of contamination by leaking.
What Residents Can Do to Ensure Safe Water
There is much government action that needs to take place on a large-scale solution; however, there are also individual actions that each citizen can take to protect themselves and their family.
Purchasing a good water purification system, like reverse osmosis or ultraviolet filtration, is one of the best preventative steps you can take as a citizen to ensure safety for both your family and yourself. This is particularly important when filling your water supply from a bore well or tank.
It is also important to regularly test your water supply for Total Dissolved Solids (TDS) and the presence of other harmful contaminants. This can be done by purchasing an at-home testing kit or utilizing laboratory services to monitor your water supply.
Boiling your water before drinking it may also help reduce the chance of illness from contaminated drinking water, especially during periods of suspected contamination.
When filling your water supply from a tanker, always ensure you are receiving your water from a reputable vendor, and always use clean containers to store any water obtained through tankers. Finally, you must implement a rainwater collecting system for your home.
FAQs
1. Is it safe to drink tap water in Chennai?
“Not usually.” While the municipal water supply is treated, there are many factors that can affect the quality of the water (for example, pipeline issues and potential contamination, etc.). It is therefore advisable to always filter or boil your drinking water before consuming.
2. Why does borewell water in Chennai taste salty?
“Saltwater intrusion is the cause of the salty taste. This occurs when seawater mixes with groundwater due to high extraction rates.”
3. Which type of water purifier is most effective for homes in Chennai?
“If you live in an area with high Total Dissolved Solids (TDS), you should consider purchasing an RO purifier.”
4. How do I perform a water quality test at home?
“You may purchase both home water testing kits and pay for professional laboratory testing to determine TDS levels and identify potential contaminants.”
