lality, can be achieved with a wide range of total water intakes (e.g., first through 99th percentile of total water intake) (Appendix Table G-1). Therefore, the AI for total water is set based on the median total water intake using data from NHANES III (Appendix Table D-1) and rounding to the nearest 0.1 L.

Based on these data, the median total water intake for children 1 to 3 years of age was 1.3 L/day, children 4 to 8 years was 1.7 L/day, boys 9 to 13 years was 2.4 L/day, boys 14 to 18 years was 3.3 L/day, girls 9 to 13 years was 2.1 L/day, and girls 14 to 18 years was 2.3 L/ day.

The percent of total water that was consumed from foods was 29 percent for ages 1 to 3 years (0.38 L/day), 29 percent for ages 4 to 8 years (0.51 L/day), 24 percent for boys 9 to 13 years (0.58 L/day), 20 percent for boys 14 to 18 years (0.67 L/day), 24 percent for girls 9 to 13 years (0.52 L/day), and 20 percent for girls 14 to 18 years (0.46 L/day) (derived from Appendix Table D-1 and D-4, by dividing the median in Table D-4 by the median in Table D-1).
