         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 143_NATIONAL SECONDARY DRINKING WATER REGULATIONS--Table of Contents
 
Sec.  143.1  Purpose.

    This part establishes National Secondary Drinking Water Regulations 
pursuant to section 1412 of the Safe Drinking Water Act, as amended (42 
U.S.C. 300g-1). These regulations control contaminants in drinking water 
that primarily affect the aesthetic qualities relating to the public 
acceptance of drinking water. At considerably higher concentrations of 
these contaminants, health implications may also exist as well as 
aesthetic degradation. The regulations are not Federally enforceable but 
are intended as guidelines for the States.
