In contrast, the chalk that is in water has no such reaction. Concentrations greater than the recommended value for drinking water of 500 mg/L give water an unpleasantly salty taste. Intensive studies by the USGS National Water-Quality Assessment (NAWQA) Project in agricultural areas provide insight into how agricultural activities have altered the natural flow of water and the way that agricultural chemicals enter streams and aquifers, and in particular how nutrients affect algal and invertebrate communities in agricultural streams. While this reaction could proceed in theory, it is extremely energetically unfavorable. Although groundwater is a safe, reliable source of drinking water for millions of people nationwide, high concentrations of some chemical constituents can pose potential human-health concerns. The bottom line is that things dissolve in water when the water molecule will adhere strongly to the different subunits of the molecules of the solid and it will not dissolve if the adhesion between between particles of the solid is strong enough and that is the case for chalk.
