Question: How does our water get dirty?

Water can get dirty in many different ways. Can be contaminated on rivers and lakes with virus, bacterias, very little things we cannot see and might be bad for our body if we drink them.
Once you shower, wash the dishes, etc, that clean water from the tap gets also contaminated with the soaps and all the products you use, being dirty again!
