✔✔Springs - ✔✔a. Formed at the intersection of an aquifer with the ground surface
b. Not always of good microbiological quality
✔✔Wells - ✔✔a. Water should be clear, cool, colorless, and uniform in character
b. Usually better microbiological quality and contains much less organic material than
spring or surface water
