Groundwater Is Facing The Contamination Risk Due To Human Activities

Many human activities are causing pollution of air and water which results in toxic pollutants that are released into the environment. It is shocking to note that due to such activities even the groundwater is suffering contamination risk.

Groundwater Contamination

Groundwater is present below the earth’s surface in soil pores. This water is accumulated into grounds due to rains. The formation of groundwater takes thousands or millions of years.

To study the link between groundwater and human activities the researchers have gathered the samples from a depth of 820 feet below the ground. The water present at this depth is known as fossil because it is formed after thousands of years. The collected sample was then tested and researchers analyzed the evidence of rainwater that was mixed with the ancient sample. The researchers noticed the presence of tritium which is a radioactive isotope of hydrogen that is found in contaminated waters.

It was earlier thought that this groundwater is resistant to contamination but the latest study has proved that this is not true. The carbon signature of groundwater was used to determine the age of fossil that was at least 12,000 years old. As this is very long time span the researchers claim that the fossil may not be contaminated due to human activities. Hence, they were shocked to see the contaminated groundwater.

The researchers think that the contamination may have taken place due to leakage and holes in the whales which are the traditional way to draw water. Also, amongst these gathered sampled it was seen that 50% of them were already contaminated due to pollution. It is the need of time to conserve this under groundwater reserves. If they get polluted then it will be difficult to grow crops. This indirectly will cause food contamination.  The research study has been published in the journal Nature Geoscience.
