1 with 77 complete solutions.
Air Gap - ANSWER A physical separation sufficient to prevent backflow between the free-flowing
discharge end of a potable water system outlet and any other system.
Backflow - ANSWER The flow of non-potable water or other liquids, mixtures, or substances into the
potable water supply system.
Back-siphonage - ANSWER Backflow resulting from negative pressures in the distribution pipes of
potable water systems.
Backflow Prevention Device - ANSWER A device or means designed to prevent backflow or back-
siphonage.
Check Valve - ANSWER self closing device which is designed to allow the flow of fluids in one direction
and to close if there is a reversal of flow.
Chloramine (Combined Available Chlorine) - ANSWER The chlorine products formed by the reaction of
equilibrium products of ammonia with the equilibrium products of chlorine.
Containment - ANSWER Anything found in water which may be harmful to human health.
Ex: microorganisms, minerals, chemicals.
Cross Connection - ANSWER Any actual or potential connection between the public water supply and a
source of contamination or pollution.
Disinfectant - ANSWER a chemical or physical process that kills microorganisms such as bacteria, viruses,
and Protozoa.

Filtration - ANSWER A process for removing particular matter from water by passage through porous
media.
Free Available Chlorine - ANSWER chlorine available (after chlorine demand has been satisfied) in the
forms of hypochlorous acid and hypochlorite ions
Halogens - ANSWER Series of elements that are highly reactive, and as such can be harmful or lethal to
biological organisms in sufficient quantities.
Fluorine
Chlorine
Bromine
Iodine
Marginal Chlorination - ANSWER Application of chlorine to produce the desired total chlorine residual
without reference to the amounts of free or combined chlorine present.
Raw Water - ANSWER Untreated water.
Water used as a source of water supply taken from an impounded body of water.
Stream
Lake or pond
Sanitary Defects - ANSWER Conditions that may cause the contamination of a water supply during or
after treatment
Total Available Chlorine - ANSWER The sum of the chlorine forms present as free available chlorine and
combined available chlorine.
Treated Water - ANSWER Water that is ready for consumption but has undergone processing such as
sedimentation, filtration, softening and disinfection
