10. Community Water System: A public water supply that has at least 15
service connections or serves 25 or more persons on a regular basis
11. Primary Contaminants: Contaminants identifies by the EPA as harmful to
umal health
12. Maximum Containment Level (MCL): The level in which contaminants must
not exceed or public notification is required.
13. Cryptosporidium: A microsocpic parasite that can be found in water. It
produces cysts that are very resistant to harsh environmental conditions. It is
responsible for intestinal illness called cryptosporidiosis. Symptoms include
diarrhea, cramps, gas, bodily discomfort, fatigue, and weight loss. Occurs one
week after exposure and can last for 1-4 weeks
, .
14. Disinfection Profiling: A water system assesses the level of disinfection
currently provided and then determines the impact a proposed change in
disinfection practice would have.
15. E. coli: A bacterium that is commonly used as an indicator of human health
risk from harmful micro organisms that can be present in water. Symptoms
include sever cramps and diarrhea. Blood is often seen in the stool. Symptoms
begin 1-9 days after exposure and last a week or less.
16 Giardia: A microscopic parasite that can be found in water. It produces cysts
that are resistant to harsh environmental conditions. Giardia causes intestinal illness
called giardiasis. Symptoms simular to cryptosporidiosis. Vomition, chills, headache
and fever may also occur. Symptoms begin one week after exposure and can last
up to a month.
17. Hard Water: A characteristic of water caused mainly by the salts of calcium
(Ca++) and magnesium (Mg++). Undesirable due to formation of soap curds,
increase use of soap, and scale deposits in boilers and water heaters. Defines
as having hardness of 100mg/L or greater
18. Maximum Residual Disinfectant Level (MDRLs): The highest level of
disinfectant allowed in drinking water. Standards set by the US EPA
19. Microbial Pathogens: Micro-organisms that cause disease
20. Safe Drinking Water Act (SDWA): An Act passed by the US Congress in
1974. It establishes a cooperative program among local, state, and federal
agencies to ensure safe drinking water for customers.
21. Ch 1 - One gallon of water weighs: 8.34 pounds
22. Ch 1- The average domestic water usage per person per day is usually
somewhere in the range of: 100-130 gallons
23. Ch 1 -Probably the most important source of information to use when
implementing changes in process control at a water plant is: Lab Results
24. Ch 1 - The most important duty of a water plant operator is to: Help to
protect the health and well-being of the community
25. Apparent color: The color visible in water
26. True color: Dissolved material contribution to color and is not removed
through simple filtration (i.e. coffee or tea). Measure in Color Units (CUs) using
a clear glass tube called a Nessler tub.
27. Turbidity: Particles suspended in water. These particles can be removed
through filtration. This is considered a primary contaminant by the EPA. These
particles can surround and protect harmful microorganisms from being
destroyed by chlorination.
28. Nephelometric Turbidity Unit (NTUs): A measure of turbidity
