What is the importance of preserving Ground water?
Groundwater in aquifers is one of our most important natural resources, but overuse and pollution from human activities are threatening aquifer viability, causing economic problems, public health problems, and even water conflict. When an aquifer is exhausted, the earth above it tends to sink into the empty gap, thereby sealing off the aquifer for good.
Human activities are already depleting aquifers far faster than natural systems can replace them. Groundwater accounts for up to 33% of worldwide water withdrawals. More than 2 billion people rely on groundwater as their primary source of water, and aquifers supply half of agricultural irrigation water.
One of the most serious risks to aquifers is population increase. More people equals more human activities, whether domestic, agricultural, or industrial. Water consumption is increasing as a result of industrialization and improving living standards.
The aquifer underneath India is vast, but it is tainted with industrial arsenic and, to make matters worse, is gradually depleting. In India, polluted water is responsible for 40% of all deaths. Contamination, however, is not limited to the poor world. Nitrate pollution from agricultural fertilizer has contaminated most of rural India's drinking water.
One may expect to hear that the issue is climate change-related sea level rise, yet aquifer depletion is the bigger issue. When aquifers beneath the city are depleted, the ground beneath the city begins to sink. That also applies to rural agricultural land on the other side of the globe.
Depletion in coastal places across the world causes saline intrusion into aquifers when saltwater seeps in to fill the hole, making aquifers brackish and unsuitable for most purposes unless treated. Water management in India includes pumping fresh water into aquifers to prevent salty encroachment.
Groundwater Protection Methods
Natural processes cannot refill depleted aquifers as quickly as rising people can, but humans can assist. Pervious concrete pavement, for example, permits water that would otherwise be disposed of in gutters to seep into aquifers. Managed aquifer recharge (MAR) detects and redirects water to areas that are optimal for water to enter aquifers.That also applies to rural agricultural land on the other side of the globe.
Netsol offers MABR in two product lines: Smart Packaged Plants, which is appropriate for decentralized treatment, and Retrofitted MABR Modules, which allows existing wastewater treatment plants to be retrofitted with MABR modules.
Aquifers of Brackish Water
Where seawater has already polluted aquifers, brackish-water desalination is becoming a more practical alternative. In reality, desalinating brackish water is less difficult and less expensive than desalinating saltwater. Desalination of brackish groundwater is becoming increasingly practical as technical breakthroughs reduce the high cost of desalination.
There are enormous brackish aquifer water reserves in India's coastal areas that are subject to saltwater intrusion.
Although the area has not yet experienced water shortages sufficient to justify accessing the brackish aquifer, experts believe the finding implies that similar underwater aquifers are ubiquitous globally, providing a potentially infinite source of water that is far more easily desalinated than saltwater.
What can we offer?
A variety of Netsol Water products may assist communities in properly converting their wastewater into high-quality effluent, allowing them to recharge their aquifers or sustain themselves on brackish water reserves.
