Prepare an article suggesting some method to recharge ground water.
Answers
AnsNatural replenishment of ground water reservoir is a slow process. But when this natural process of recharge is disturbed or hindered- due to rapid increase in groundwater abstraction, increase in paved area, decrease in rainfall etc., then arises the need of artificial recharge which is basically aimed at augmentation of the natural movement of surface water into ground water reservoir through suitable civil construction techniques. Such techniques interrelate and integrate the source water to ground water reservoir.
The process of recharge itself is not artificial. The same physical laws govern recharge, whether it occurs under natural or artificial conditions. What is artificial is the availability of water supply at a particular location and a particular time. In the broadest sense one can define artificial recharge as “any procedure, which introduces water in a pervious stratum”.
Scientifically speaking, before making a plan to recharge groundwater in a given area, some factors are taken into consideration.
•Hydrogeology of the area - aquifer disposition and parameters.
•Availability of source water - Usually non committed surplus monsoon run-off.
Artificial recharge schemes essentially involve the following major components :
•Identification and prioritization of need based areas
•Assessment of source water
•Planning of recharge structures
•Finalisation of specific techniques and designs
•Monitoring and impact assessment
•Financial and economic evaluation
•Operation and maintenance
Explanation:
1.Use native plants in your landscape. They look great, and don't need much water or fertilizer. Also choose grass varieties for your lawn that are adapted for your region's climate, reducing the need for extensive watering or chemical applications.
2.Use fewer chemicals around your home and yard, and make sure to dispose of them properly - don't dump them on the ground!
3.Properly dispose of potentially toxic substances like unused chemicals, pharmaceuticals, paint, motor oil, and other substances. Many communities hold household hazardous waste collections or sites - contact your local health department to find one near you.
4.Shut off the water when you brush your teeth or shaving, and don't let it run while waiting for it to get cold. Keep a pitcher of cold water in the fridge instead.
5.Check all the faucets, fixtures, toilets, and taps in your home for leaks and fix them right away, or install water conserving models.
6.Limit yourself to just a five minute shower, and challenge your family members to do the same! Also, make sure to only run full loads in the dish and clothes washer.
7.Water the lawn and plants during the coolest parts of the day and only when they truly need it. Make sure you, your family, and your neighbors obey any watering restrictions during dry periods.
8.Reduce the amount of "stuff" you use and reuse what you can. Recycle paper, plastic, cardboard, glass, aluminum and other materials.
9.Use all natural/nontoxic household cleaners whenever possible. Materials such as lemon juice, baking soda, and vinegar make great cleaning products, are inexpensive, and environmentally-friendly.
