illegal bathing and fishing
windblown contaminants
Which operating procedures can result in water quality degradation in a
distribution system? - ANSWERS-Poorly performed water quality
monitoring and flushing programs
inadequate cross connection control
insufficient surveillance to determine whether the protective features for
storage facilities and mains are still adequate
tolerance of low or negative pressures in the distribution system
inadequate disinfection after repair or installation of new facilities
What are some critical elements of an effective water distribution system
O&M Program? - ANSWERS-1.developing a valve exercise program to
ensure the proper setting and operation of valves
2. developing and maintaining an active corrosion control program
3.instituting an annual cleaning and lining program
4.developing a program to eliminate as many of the dead ends in the
distribution system as possible
