Developmental Fluoride Neurotoxicity: A Systematic Review and Meta-Analysis
Conclusions: The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment. Future research should include detailed individual-level information on prenatal exposure, neurobehavioral performance, and covariates for adjustment.
Aside from the meta-analyses, this was looking at studies from China in which there are areas that have well water with fluoride concentrations at greater than 1 mg/L. The EPA's maximum contaminant level goals (MCLG) is 4 mg/L and the secondary standard (SMCL) is 2 mg/L, it looks as though the U.S. national target for drinking water is generally to raise it to .7 mg/L (Fairfax VA water authority, Denver Water), but I'm having trouble finding anything on recommended levels at the a href="http://www.cdc.gov/fluoridation/">The CDC's page of fluoridation information.
