Examining the Relationship Between Safe Drinking Water Violations and Adverse Birth Outcomes in Virginia
The Safe Drinking Water Act (SDWA) was established to protect consumers from potential exposure to over 90 water contaminants. Each contaminant is assigned a health-based standard meant to reflect the maximum level at which an adverse human health outcome is unlikely; measurements beyond that level …
