Spatial and Temporal Changes in Groundwater Manganese and Infant Mortality in North Carolina

• Description:
  Manganese is ubiquitous in North Carolina, with well users at risk for excess exposure. Previous studies didn't consider long-term infant mortality rate variability or total worker health exposure in agricultural settings. In this study, manganese concentrations and infant mortality rates are evaluated throughout North Carolina from years 2000 through 2019, assessing spatiotemporal changes using Bayesian Maximum Entropy (BME) analysis. Manganese concentrations exceeded established adverse effect limits and showed variability overlooked in studies sampling for limited years. Manganese concentrations are autocorrelated over 1.25 degrees and 3.3 years while infant mortality rates are autocorrelated over 0.6 degrees and five years. Infant mortality rates were evaluated using BME interval estimation, resulting in regional maximums of up to one infant death per thousand live births attributable to manganese in the North Carolina Coastal Plain. Increased testing and advisories for private well users will aid in identifying and mitigating manganese exposure and related infant mortality. [Description provided by NIOSH]
