How does acid rain affect the buildings?
Deteriorating Buildings Acid rain damages buildings and structures because it dissolves the stone or corrodes the metal that is exposed to the weather. Some of these materials contain calcium carbonate or calcium-based compounds, which can be dissolved by acid rain.
Does Washington have acid rain?
Normal, unpolluted rain is slightly acid, with a pH of 5.6, because the carbon dioxide in air combines with water to form small amounts of a weak acid called carbonic acid. Rainfall in the Washington area has an average pH of 4.2 to 4.4, more than 10 times as acid as unpolluted rain.
How has the Washington Monument been affected by weathering?
“That stone has been weathered for more than 100 years,” said James Perry, chief of resource management at the National Park Service. It has been “patched and cracked and chipped and hit by lightning.… It’s not meant to be pristine, it’s meant to retain that character.”
What monuments have been affected by acid rain?
In response, the Indian government has established local strict emission controls to help protect the Taj Mahal. The Thomas Jefferson Memorial in Washington, D.C., is one of many monuments affected by acid rain. The dissolving calcite releases the silicate minerals contained within the marble.
What happens when buildings and statues are exposed to acid rain?
Acid rain can also have a damaging effect on many objects, including buildings, statues, monuments, and cars. The chemicals found in acid rain can cause paint to peel and stone statues to begin to appear old and worn down, which reduces their value and beauty.
What places has acid rain affected?
Acid rain is responsible for severe environmental destruction across the world and occurs most commonly in the North Eastern United States, Eastern Europe and increasingly in parts of China and India.
What effect does acid rain have on Washington DC?
In Washington, DC, the monuments in the National Mall have been impacted by acid rain. The statues have become less detailed and surfaces have changed. It’s an inevitable result of the city’s rain pH at 4.3 pH in 1997 and 4.9 pH in 2010. Acid rain can also impact buildings.
Why is the Washington Monument 555 feet tall?
Rather than ascend to 600 feet as Mills had intended in the original plan, Casey was persuaded to make the height of the structure ten times the width of the base, meaning the optimal height for the Washington Monument was 555 feet.
What are two places that have been affected by acid rain?
Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States, and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan.
Is there an acid rain problem in Washington?
Acid Rain in Washington. The problem of urban pollution and acid precipitation (often called acid rain) is of increasing concern in the Washington metropolitan area. Pure, distilled water has a neutral pH of 7.
How does acid rain affect the National Mall?

How did acid rain damage the capitol building?
The marble balustrade on the west side of the Capitol building shows damage from acid rain dissolving the mineral calcite. Questions still remain about acid rain and building stone in the Washington area. Weathering (deterioration caused by exposure to the environment) is a natural part of the normal geologic cycle.
