  2. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity with increasing numbers of energy levels. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if the metal is heated red hot. [9]

    EPA illustration of lead sources in residential buildings Infographic about lead in drinking water. The Lead and Copper Rule (LCR) is a United States federal regulation that limits the concentration of lead and copper allowed in public drinking water at the consumer's tap, as well as limiting the permissible amount of pipe corrosion occurring due to the water itself.

    Proper water-shedding design and detailing, which reduces the dwell time of acidic water on metal surfaces, can prevent the majority of atmospheric corrosion problems. [28] A copper weather vane as an architectural element. Brass, an alloy of copper and zinc, has good resistance to atmospheric corrosion, alkalis, and organic acids.

    en.wikipedia.org/wiki/Building_science

    During the architectural design process, building science knowledge is used to inform design decisions to optimize building performance. Design decisions can be made based on knowledge of building science principles and established guidelines, such as the NIBS Whole Building Design Guide (WBDG) and the collection of ASHRAE Standards related to building science.

  7. Lead service line - Wikipedia

    In the shared ownership, the water utility typically owns the communication pipe and the curb stop, and property owner owns the supply pipe. [30] In this scenario, when the water utility owned section of a lead service line is called public lead service line, and the section owned by the property owner is called private lead service line.

    Typically these have a metal, such as a copper ion, in the center and a nonmetals atom, such as the nitrogen in an ammonia molecule or oxygen in water in a water molecule, forms a dative bond to the metal center, e.g. tetraamminecopper(II) sulfate [Cu(NH 3) 4]SO 4 ·H 2 O. The metal is known as a "metal center" and the substance that ...

  9. Copper zinc water filtration - Wikipedia

    en.wikipedia.org/wiki/Copper_zinc_water_filtration

    Copper zinc water filtration is a high-purity brass water filtration process that relies on the redox potential of dissolved oxygen in water in the presence of a zinc anode and copper cathode. It uses dissolved impurities within water as constituent substrate, which are reduced to more physiologically inert compounds.
