Question

• A. Ground water
• B. Pond water
• C. River water
• D. Tap water

Answer 1

The correct option is A

Ground water

Pesticides contain chemicals that kill organisms which otherwise would have damaged the crops. When these chemicals enter our ground water, they pollute it and make it unfit for our use. The pesticides can enter our ground water either by seeping through the layers or when they get washed away by rainfall and eventually end up in our ground water. Consumption of such contaminated water may lead to a wide array of health problems.
