From the pipes and Plumbing coming into your home. :)
Metals are generally not soluble in water, with the exception of certain alkali metals and alkaline earth metals.

Metals may be naturally present in some areas (they DO come from the ground, you know) or they may enter the water table from improperly disposed of wastes. In some cases, metals may have entered the water supply by way of piping- at one time lead pipes, or coper pipes soldered together with lead was the standard water supply pipe.
Most likely, metals are in your water. If your pH is low (less than 7.0) and you have a heater with copper tubing, or some other source of metals, you may have copper dissolved in your water. Have your local pool supply store test for metals and if the test is positive, use a chemical like "Metal Free" at a rate of one liter per 20000 gallons.
There are various compounds for this sold in plumbing shops.
due to Municipal water supply malfunctions there may be improper water supply
A well water inspection is important to ensure the safety and quality of the water supply. It helps identify potential contaminants such as bacteria, chemicals, or heavy metals that may be present in the water. By conducting regular inspections, any issues can be detected early and addressed promptly to prevent health risks and ensure the water is safe for consumption.
Metals such as lead, mercury, and cadmium are not suitable to be used as pipes due to health risks associated with leaching into the water supply. Additionally, metals that easily corrode, like aluminum and magnesium, may not be ideal for long-term pipe use.
Supply coming from water source is a water service line.
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
Metals that have a density greater than the density of water will sink in water, while metals that have a density less than water will float. For example, metals like lead, gold, and silver will sink in water, while metals like aluminum and lithium will float.
