Plots of children's simulated heights at ages 12, 18, 24, and 30 months. Each height measurement is the sample mean of 100 independent replications, with error bars indicating standard deviations. At the current water quality level of the sources, simulation results indicate stunting of both male and female children. When provided with quality water (best case), children grow along the WHO normal growth curves. At extreme coliform levels, the children are stunted to about -1.50 standard deviations of the WHO height norms (middle curve, with +2 and -2 standard deviations indicated by the top and bottom curves, respectively).

Figure 7 shows the effect of water quality on child growth in the modeled villages.
