#WORLDCANCER DAY – #Causes Of Cancer ? , #Groundwater Pollution, #Enviromental Pollution

There are many causes of cancer out of which unhealthy ground water is very important factors in metro cities
1- #Storage Tanks
May contain gasoline, oil, chemicals, or other types of liquids and they can either be above or below ground.
2-#Septic Systems
Onsite wastewater disposal systems used by homes, offices or other buildings that are not connected to a city #sewer system.
3-Uncontrolled #Hazardous #Waste– there are thought to be over 20,000 known abandoned and uncontrolled hazardous waste sites and the numbers grow every year. #Hazardous #waste sites can lead to #groundwater #contamination if there are barrels or other containers laying around that are full of hazardous #materials. If there is a leak, these contaminants can eventually make their way down through the #soil and into the #groundwater.
4-landfill -(car battery acid, paint, #household cleaners, etc.) can make their way down into the groundwater.
5-#Chemicals and Road Salts
The widespread use of #chemicals and road salts is another source of potential groundwater contamination. #Chemicals include products used on lawns and farm fields to kill weeds and insects and to #fertilize plants, and other products used in homes and businesses. When it rains, these chemicals can seep into the ground and eventually into the water.
6-#Atmospheric #Contaminants
Since groundwater is part of the #hydrologic cycle, contaminants in other parts of the cycle, such as the #atmosphere or bodies of surface water, can eventually be transferred into our #groundwater supplies.
7-#factories #waste
There are so many #factories around or near the #metros put the waste in ground water through bore well
8- #Environmental #pollution
#Delhi & ncr is maximum #polluted #city in world contains maximum #carcinogens for #lungs & #airway.
