The rise and fall of the Delaware River salt front. Over time, the location of the salt front moves in response to regional weather patterns, sea level rise, and human impacts. The precise location of the salt front in the Delaware River Basin is based on the location in the river where the average chloride concentration is 250 mg/L.
