that are out of compliance
Ch. 62-602 Correct Answers Drinking water and domestic wastewater
treatment plant operations
Ch. 62-699 Correct Answers Classification and staffing of water or
domestic wastewater treatment plants and water distribution systems
MCL for arsenic Correct Answers 0.010 mg/L
MCL for lead Correct Answers 0.015 mg/L
MCL for Nitrate Correct Answers 10 mg/L
MCL for turbidity Correct Answers 5 NTU
,MCL Fluoride Correct Answers 4 mg/L
MCL for sodium Correct Answers 160 mg/L
MCL total THM Correct Answers .08 mg/L
MCL total coliform Correct Answers No more than 5% per month (if
sampling more than 40 month)
MCL for pH Correct Answers 6.5-8.5
MCL for Chlorine residual, free Correct Answers .2 mg/L
MCL for Chlorine residual, total Correct Answers .6 mg/L
Head Loss Correct Answers The head, pressure or energy (they are the
same) lost by water flowing in a pipe or channel as a result of turbulence
caused by the velocity of the flowing water and the roughness of the
pipe, channel walls, or restrictions caused by fittings. Water flowing in a
pipe loses head, pressure or energy as a result of friction losses. The
head loss through a filter is due to friction losses caused by material
building up on the surface or in the top part of a filter.
, C Factor - definition and range Correct Answers Higher the c factor, the
smoother the pipe. Ductile and Cast Iron - lowest ~ 100
PVC, PE, PLASTIC-highest ~140 -150

ft preferably - at least 1 ft higher
How often should coliform testing be conducted? Correct Answers
Every month - MCL violation if more than 5% of samples are positive
What is the chemical found in the specially prepared bottles that are
used for coliform testing? Correct Answers Sodium Thiosulphate
MCL for copper Correct Answers 1.3 mg/L
Order of backflow devices in terms of effectiveness: Correct Answers
Air gap, Reverse pressure, double check valve assemblies, dual check
valves, vacuum breakers
What is the normal pressure range in PSI and what is the minimum
pressure range in PSI? Correct Answers Normal operating pressure
range is 35 to 100 PSI. The minimum working pressure that the main
should not drop below is 20 PSI
