Actually, Jesse.  I have read the Bashash study, numerous times, which is why I know that neither you nor Kailin have read it.

The urine analysis was used as a biomarker for total fluoride intake of pregnant women living in non-fluoridated Mexico.  The authors of the study, themselves, clearly state that they did not know the fluoride concentration of the water consumed by these women.

“Other limitations include...... the lack of data on fluoride content in water given that determination of fluoride content is not reported as part of the water quality monitoring programs in Mexico; ...”

Additionally, not only was there no such finding that “at 0.7 ppm, CHILDREN HAD LOWER IQs.”,  there was no effect found on children 1-3 years old, and they reported evidence that in the other children no effect occurred below the level of 0.8 mg/L.

“there was some evidence that associations with IQ may have been limited to exposures above 0.8 mg/L.”
