Answer:
Explanation:
Building and business closures for weeks or months reduce water usage, potentially leading to stagnant
water inside building plumbing. This water can become unsafe to drink or otherwise use for domestic or
commercial purposes. For example, optimal growth conditions for undesirable pathogens, such as
Legionella bacteria, can occur when hot water temperatures decrease and disinfectant residuals (e.g.,
chlorine) drop to low levels. Water chemistry changes may also increase corrosion and leaching of
metals, including lead, and may cause the formation of disinfection by-products. Turning on the water
for immediate use after it has been stagnant can pose a risk to public health if not properly managed.
Additionally, turning on water after a prolonged period of non-use could disrupt pipe and plumbing
scales to such an extent that microbial and chemical contaminants could be released into the water.

While he was still alive, Wegener was best-known for his achievements in <span>meteorology and as a pioneer of polar research, but today he is most remembered as the creator of the theory of the continental drift. This idea was controversial in the beginning, but today, scientist believe that Pangaea really existed during the late Paleozoic and early Mesozoic eras.</span>
