What Makes Water Unsafe?

Water is hazardous when it contains germs, worms, or toxic chemical compounds (for more about toxics, see next section). Germs (tiny living things, too small to see, that reason many kinds of illness) and worms, such as whipworm, hookworm, and roundworm, reason many serious illnesses. 

Germs and worms stay in human and animal waste (urine and feces) and can purpose serious and long-lasting ailments when:

• There is now not a accurate way to get rid of human and animal wastes.
• Water supplies are not blanketed and saved clean.
•There is not sufficient water to wash. 

Some of the illnesses they cause, such as cholera, unfold rapidly and can reason many deaths. Other ailments from germs and worms can reason years of illness and lead to other health problems such as dehydration, infections, anemia (weak blood), and malnutrition. Because the most common sign of illnesses from germs and worms is diarrhea, these ailments are every so often called diarrhea diseases.
