Elevated levels of sodium in well water are being reported across the state of Maryland, and for residents with high blood pressure, drinking the recommended daily amount of water could increase the amount of sodium consumed, and therefore affect their health, say University of Maryland Extension researchers.

A new UMd Extension publication, “Sodium in Your Well Water: A Health Concern,” highlights the rising salinity levels in Maryland groundwater and aquifers, and provides advice for understanding sodium levels in tap water from private well systems.
