What are the problems with quarrying limestone?

What are the problems with quarrying limestone?

Quarrying creates pollution from noise and dust. Heavy traffic causes pollution and congestion on narrow country roads. The vibrations from heavy traffic can cause damage to buildings. Quarries create visual pollution and tourists may be deterred by the scars on the landscape.

Does limestone contaminate water?

Groundwater. Groundwater quality can be affected by quarrying limestone by increasing sediment and accidental spills directly into the aquifers. Because contaminants in ground water move faster through limestone than other types of rocks, quarries in karst areas must be especially careful.

How do quarries affect water quality?

Pits and quarries disrupt the existing movement of surface water and groundwater; they interrupt natural water recharge and can lead to reduced quantity and quality of drinking water for residents and wildlife near or downstream from a quarry site. Most old pits and quarries are not being properly rehabilitated.

How does limestone quarrying affect the environment?

Globally there have been numerous cases of environmental degradation caused by limestone quarrying and processing: research has proven that such anthropogenic activities give rise to an exceedingly alkaline river water, vegetation growth inhibition and fungi and bacteria proliferation.

How does limestone mining affect the water quality?

In Germany, salty water pumped from limestone quarries into rivers has degraded the water quality, according to the International Mine Water Association. Upstream surface water features, such as marshes, ponds and wetlands, can lose volume as their waters drain into the mine and are pumped out.

What are the health effects of quarrying limestone?

Quarries may have a negative health impact. Stringent health and safety regulations can offset some of the negative health impacts that quarrying limestone may cause, but not all of them. Inhaling the dust from a limestone quarry is known to cause silicosis and pneumoconiosis.

What happens when Limestone is added to a pond?

The limestone will act as a coagulant which causes the algae and the phosphorous to settle to the bottom of the pond. As phosphorus is an essential element for algae reproduction, this will result in fewer algae growth over the following season. It’s not a method of removal algae but preventing method.

How does hydrated lime improve water quality in ponds?

However, recent studies have shown that the use of hydrated lime is a more complete and longer lasting method of improving water quality in ponds as limestone prevents the acidification of the water and prevents algae blooming.
