(1) Included in FDA's 9 contaminant regulations.
(2) Included in FDA's D/DBP rule. See D/DBP monitoring requirements section on page 19 in Appendix A for details.
(3) SOQ dependent upon temperature and other factors. See fluoride section on page 20 of Appendix A for details.
(4) SMCL = Secondary maximum containment level. SMCLs are guidelines established by the USEPA for use in evaluating aesthetic.
(5) Mineral water is exempt from allowable level. The exemptions are aesthetically based on allowable levels and do not relate to a health concern.
All SOQs, MCLs, SMCLs, and guidelines in mg/L (ppm) except as noted.
