Answers
Nothing is quite as refreshing as a glass of water. On a hot summer day, some ice water really does the trick. On a cold winter day, a nice cup of hot tea will take away the chill. Do you drink coffee in the morning? You need water for that, too!
We take for granted that we have easy access to clean water for drinking, washing dishes and cleaning our clothes, but water isn't always clean. A body of water, such as a lake, stream, river, pond, ocean and even the water underground in the soil, can become polluted when it's contaminated by sewage leaks, agricultural runoff or chemical spills. When water is polluted, it becomes unsafe for human consumption because the water contains dangerous or toxic substances and disease-causing bacteria and organisms.
Pollution may be caused by natural sources or human activities, but regardless of the cause, the result is the same. It can have detrimental effects on aquatic ecosystems as well as the health of those who depend on those sources of water, like us!
Pollution can be difficult to determine because it is not always visible, so scientists use a variety of techniques and tests to measure water quality and the level of contaminants.
