These passive compounds form on the surface preventing the zinc metal from reacting with oxygen and chlorides which slows the corrosion rate. Water Hardness Effect to Galvanized Steel Corrosion

Calcium

Acute and Chronic Effects: Calcium will react with water or moisture causing heat. If calcium metal contacts moisture in the eyes, on the skin, or in the respiratory tract, severe corrosive irritation may result. The fumes evolved by burning calcium in air are composed of calcium oxide which is an irritant to the skin, eyes and mucous merane.

7 Health Effects of Lead in Drinking Water | ActiveBeat

Some homes in the U.S. (especially those built before 1986) still contain lead service pipes, and lead can end up in drinking water when the lead pipes corrode. A person can have short-term effects from very high levels (lead poisoning), or display symptoms of long-term lead exposure at lower levels.

Experimenting with the Effect of Water Quality on Coffee

Experimenting with the Effect of Water Quality on Coffee. Calcium and magnesium are metals dissolved as charged particles in water (Ca 2+ and Mg 2+). The positive charge is important, because most of the flavour compounds in coffee are negatively charged when dissolved in water, which means they are attracted to the positively charged metal

REACTIONS OF THE GROUP 2 ELEMENTS WITH WATER

Calcium, strontium and barium. These all react with cold water with increasing vigour to give the metal hydroxide and hydrogen. Strontium and barium have reactivities similar to lithium in Group 1 of the Periodic Table. Calcium, for example, reacts fairly vigorously with cold water in an exothermic reaction.
