Is Groundwater pure?

Ground water have good minerals. And also there are some impurities are there. We are the best aquaguard service center in chennai. We offer general service for your water purifier.

When rain falls to the ground, some of it flows along the land surface to streams, rivers or lakes, some moisturizes the ground. Part of this water is used by vegetation; some evaporates and returns to the atmosphere. Part of the water also seeps into the ground, flows through the unsaturated zone and reaches the water table, which is an imaginary surface from where the ground beneath is saturated.

Why is groundwater so important?

Groundwater counts in average for one third of the fresh water consumed by humans, but at some parts of the world, this percentage can reach up to 100%. It is a very important natural resource and has a significant role in the economy and the main source of water for irrigation and the food industry. In general groundwater is a reliable source of water for the agriculture and can be used in a flexible manner:

For the environment groundwater plays a very important role in keeping the water level and flow into rivers, lakes and wetlands. Specially during the drier months when there is little direct recharge from rainfall, it provides the environment with groundwater flow through the bottom of these water bodies and becomes essential for the wild life and plants living in these environment. Groundwater also plays a very relevant role in sustain navigation through inland waters in the drier seasons. By discharging groundwater into the rivers it helps keeping the water levels higher.

 

Ground water serves many purposes

Fresh groundwater was used for many important purposes, with the largest amount going toward irrigating crops, such as the delicious eggplants, squash, and rutabagas that children love to have for dinner. Local city and county water departments withdraw a lot of groundwater for public uses, such as for delivery to homes, businesses, and industries, as well as for community uses such as fire fighting, water services at public buildings, and for keeping local residents happy by keeping community swimming pools full of water. Industries and mining facilities also used a lot of groundwater. In 2010, 19 percent of freshwater usage by industries came from groundwater, and 50 percent of freshwater usage at mines was groundwater. The majority of water used for self-supplied domestic and livestock purposes came from groundwater sources.

Is ground water pure?

This question seems to have attracted a lot of poor-quality answers from people ignorant about what constitutes good drinking water quality.

Ground water contains mainly minerals. So it is good. It is filtered by the great nature in the different layers of soil. So it safer and healthier than fresh water found on surface of the earth in lakes ,ponds ,Rivers ,etc as it is always in contact to the air and so contains many bacteria also as well harmful gases and substance like so2, so3,compounds of nitrogen, co etc. beside the taste of ground water is sweet which enhance your mood , makes you happy and allows your will to drink more water and hence is fills the deficiency of water in the body which prevents many disease like ulcers ,digestive problems ,enhance brain efficiency , etc.

But today due to pollution, the ground water is getting contaminated. Many harmful pollutants get mixed with it today.

Earlier people used to drink ground water throughout their lives as there were no purifying machines available or out of budget. They were stronger than we are especially in physical strength and disease fighting strength or will power.

Many of purifying machines purify water too much making it bitter to taste and unhealthy. It removes the entire mineral from it also the good ones.

Ground water purification

With population of over a billion, India is a major user of groundwater. Currently, the annual extraction of ground water in India is estimated to be about 210bcm (billion cubic meters), the highest in the world. India is also the world’s the biggest user of groundwater for irrigation. There is significant use of groundwater in almost all parts of the country except in Orissa, Assam, Bihar, Chattisgarh, Jharkhand and Jammu and Kashmir. Another more worrying dimension that has emerged in the past two decade is a direct link between industrial, agricultural and household activities, and contamination of groundwater.

Contamination of the water table is caused mainly through dissolution of two broad classes of chemicals

  • Inorganic minerals, salts, and metals
  • Synthetic organic compounds

Most inorganic compounds are harmless at the concentrations commonly found in unpolluted groundwater, and some, such as potassium, magnesium, and calcium, are even beneficial to human health. Others, such as arsenic, barium, or mercury, can occur naturally in concentrations that are considered harmful. Human activities are another source of inorganic substances in groundwater. Bacteria, viruses, or parasites can seep into the groundwater from sources such as septic systems, leaky sewer lines, barnyards, or fields spread with manure

Organic compounds are chemicals containing carbon and other elements such as hydrogen, nitrogen, or chlorine. Many occur in nature, and many others are manufactured for a wide range of purposes, including cleaning fluids, wood preservatives, and pesticides. The production of synthetic organic compounds has increased more than 10-fold in the past 40 years, and some of these chemicals have become significant groundwater contaminants.

 

Studies estimate that nearly 59% of all districts in India have problems related to either the quantitative availability or quality of groundwater. Out of the 593 districts in India from which data is available, several have problems due to high fluoride content (203 districts), iron content (206 districts), salinity (137 districts), nitrate content (109 districts) and arsenic content (35 districts) in their ground water sources. Biological contamination causing intestinal disorders are present throughout the country.

There are two distinct separation technologies – ion exchange resins and Reverse Osmosis (RO) membrane elements – which can be either used separately or together to bring ground water to safe levels.

Synthetic ion exchange resins are polymers that are capable of exchanging particular ions within the polymer with ions in a solution that is passed through them. They are used either to soften the water or to remove the mineral content altogether, but also for various other applications including separating out some elements. Water purification using this method is environmentally friendly because it deals with substances already occurring in water. The long life of resins and low maintenance of the purification equipment makes this a very attractive method.

Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent passes to the other side.

The situation with groundwater being the way it is, using water straight from the source is no longer an option. What really is a matter of choice is the type of purification system one would use.

Now we are pushed to use water purifier. Because the water is contaminated with pollution. So we must use the purifier.   Aquaguard tollfree number chennai is 9940492121.
