Sec. 230.50  Municipal and private water supplies.

    Note: The effects described in this subpart should be considered in 
making the factual determinations and the findings of compliance or non-
compliance in subpart B.


    (a) Municipal and private water supplies consist of surface water or 
ground water which is directed to the intake of a municipal or private 
water supply system.
    (b) Possible loss of values: Discharges can affect the quality of 
water supplies with respect to color, taste, odor, chemical content and 
suspended particulate concentration, in such a way as to reduce the 
fitness of the water for consumption. Water can be rendered unpalatable 
or unhealthy by the addition of suspended particulates, viruses and 
pathogenic organisms, and dissolved materials. The expense of removing 
such substances before the water is delivered for consumption can be 
high. Discharges may also affect the quantity of water available for 
municipal and private water supplies. In addition, certain commonly used 
water treatment chemicals have the potential for combining with some 
suspended or dissolved substances from dredged or fill material to form 
other products that can have a toxic effect on consumers.
