[Code of Federal Regulations] [Title 40, Volume 24] [Revised as of July 1, 2005] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR230.50] [Page 270] TITLE 40--PROTECTION OF ENVIRONMENT CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED) PART 230_SECTION 404(b)(1) GUIDELINES FOR SPECIFICATION OF DISPOSAL SITES FOR DREDGED OR FILL MATERIAL--Table of Contents Subpart F_Potential Effects on Human Use Characteristics 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 prod ucts that can have a toxic effect on con sumers.
