Question 8

Reverse Osmosis (RO)

Answer 8

The reverse of the natural osmosis achieved by external application of sufficient reverse pressure to cause the solvent to flow in its unnatural direction

Question 9

Colilert / Colisure

Answer 9

Test used to detect total coliform and E. coli in the potable water

Question 10

Total Coliform

Answer 10

• Are a group of closely related, mostly harmless bacteria that live in soil and water as well as the guts of animals
• The extent to which total coliforms are present in the source water can indicate the general likelihood that the water is contaminated with fecal matter
• The presence or absence of total coliform bacteria is the drinking water standard.

Question 11

E. Coli

Answer 11

• A type of fecal coliform bacteria commonly found in the intestines of animals and humans
• E. coli is short for Escherichia coli
• The presence of E. coli inin water is a strong indication of recentsewageor animal contamination
• Sewage may contain many types of disease-causing organisms
