In the United States, the Safe Drinking Water Act of 1974 required the EPA to set standards for allowable quantities of chemicals in water. It also authorized local governments to monitor and maintain these standards. Local governments also have the authority to set more stringent standards than those required by federal law. Suppose you work for a municipal water department for a city with 200,000 people, and your job is to design a program that ensures people have safe drinking water with low lead levels. Build your monitoring program below. Note that "action level" refers to the threshold level of lead in the water above which a sample is considered high. For each of the categories, select the option that is most likely to keep the public safe.

1)Ensure pure collection of water. 2)Ensure thorough screening of water. 3)Ensure accurate chemical addition. 4)Ensure the disinfection of the water. 5)Ensure accurate coagulation:This means adding compounds into the water. 6)Ensure sedimentation of water:This is a water treatment that gravity is used to remove suspended solids from water. 7)Ensure pure filtration. 8)Ensure safe storage. 9)Ensure safe distribution.

Explanation:

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
