2. 2.

   Name one visible characteristic of water that suggests contamination.

   Hint

3. 3.

   What is the primary purpose of water quality screening?

   • To provide quick safety assessments
   • To conduct detailed chemical analyses
   • To compare water sources

   Hint

   Consider how urgency plays a role in public health.

4. 4.

   True or False: Organic compounds typically dissolve better in water than inorganic ones.

   • True
   • False

   Hint
