2. (6 points) What are 2 ways in which water treatment facilities help stop the spread of infectious diseases?

## Step 1<br />Water treatment facilities play a crucial role in preventing the spread of infectious diseases. The first way they do this is by purifying water. This process involves removing harmful microorganisms such as bacteria, viruses, and parasites that can cause diseases. The purification process typically includes filtration, sedimentation, and disinfection. These methods ensure that the water is safe for consumption and use, thereby reducing the risk of waterborne diseases.<br /><br />## Step 2<br />The second way water treatment facilities help stop the spread of infectious diseases is by managing wastewater. Wastewater from households, industries, and other sources often contains pathogens that can cause diseases. Treatment facilities use various methods to treat this wastewater before it is discharged back into the environment. This process not only prevents the spread of diseases but also ensures that the water released into the environment is safe for ecosystems and human health.
