We examine autism prevalence in New Jersey (USA) and its relationship to sulfate in local tap water. Our previous work indicates that sulfate deficiency during early development increases the risk of autism. In this current study, prevalence is obtained from the report “New Jersey Autism Registry” on the state Department of Health website. The report analyzes prevalence for eight-year-old children born in 2006. The sulfate concentration of public water is calculated from test data reported in the Drinking Water Watch database. Counties are grouped into five prevalence ranges and tap water analyzed for the years 2005-2008, a period covering pregnancy through infancy. For this data set, the population weighted sulfate means correlate strongly with prevalence (correlation r=-0.94, n=10, p<0.001). This correlation, the literature and previous work suggest that increasing sulfate in food and water may help reduce the incidence of autism.
