Chlorides in Fresh Water
softeners remove magnesium and calcium ions from hard water by performing an ionic exchange reaction with sodium chloride. Small amounts of sodium enter water that has passed through the softener, while magnesium chloride and calcium chloride are stored in the device and eventually discharged as brine into a sewer or septic system.

cels.uri.eduFor drinking water, DEM has set a maximum contaminant level of 250 ppm chloride, which is the point at which water starts to taste salty. Some research suggests that, with certain exceptions, fish are less sensitive to chloride exposure than small, free-floating planktonic crustaceans (Evans and Frick, 2001). These
Dissolved Oxygen and Temperature
cels.uri.edusure, lakes in higher altitudes usually have lower levels of DO. Groundwater, which does not have contact with the atmosphere, typically has lower levels of DO than surface waters. When groundwater enters a lake, DO concentrations are initially reduced near the spring (Caduto 1990). However, groundwater is generally colder than surface waters ...
