A total of 87 per cent of studied quarries represent serious hazards to groundwater quality. In general, a total of 272 quarries have high impact, 657 quarries have moderate impact, and 349 quarries have low impact on natural ecosystems. Analyzed data revealed that around 62 per cent of the quarries are located in a highly unsuitable environment.
Aug 18, 2017· Environmental Impact Most directly quarrying removes rock and soil depleting natural resources and changes the topography and impacts the natural drainage pattern. In addition, quarrying comes with associated problems like air pollution (huge amounts of suspended particulate and dust emissions which defaces everything and cause respiratory disorders to ers ing in the
Of course, each pit or quarry has unique characteristics and impacts, but every pit or quarry will degrade the natural environment. For pits or quarries situated on lands designated as ecologically significant, this degradation has an even greater adverse impact. For communities, the displacement of water resources is one of the biggest concerns pits and quarries pose. However, there are many other
The impacts of quarrying on sur- face water and ground water (see below) can impact wetland riparian, and aquatic habitat which, in turn, can impact biota. Water Quality. Karst systems have very low self- puri fi cation capabilities (Kresic and others, 1992), which makes karst water very susceptible to

However, only a small portion of the EPL is required for the quarry and cement. READ MORE
Rains: the life source of shallow pools. With the onset of the rains, some previously dry places in and around the quarry have become inundated with water and life has resumed for some organisms such as the water boatman, frogs, many aquatic insects and some gastropods.
Several serious environmental impacts related to quarrying activities on and near the river, such as vibrations, land degradation, land subsidence and landslides, water pollution, occupational
Apr 01, 2001· quarries. Like all other industrial processes, the environmental impact of limestone. quarrying has to be assessed in terms of its effects on air quality, groundwater, ecology, a
Quarry operations impact the environment in several ways, for instance quarry dust can change the chemistry of water resources by dissolving in them. Noise and mechanical shakes from blasting disturbs biodiversity and even humans who live nearby. Dust from quarry activities has been known to be the cause of many respiratory diseases and conditions.

At all three sites, the quarry dewatering has altered the local ground-water hydrology. In essence, the quarries act as huge wells, lowering the water table in the aquifer. The impact of the dewatering at the Kraemer Quarry is shown in Figure 2. This lowering could affect Figure 2. The impacts on ground-water levels of drawdown at Kraemer Quarry.
The environmental effects of noise and dust vary depending not only on the size and location of the blast but also on atmospheric conditions such as wind and humidity. Dust or particulate matter suspended in the air, in an important component of air quality and is commonly generated by blasting. Noise, or air-over-pressure, as professional
Apr 25, 2017· Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
1.5 Approach to this Environmental Impact Assessment In response to concerns raised during the Scoping Phase, further specialist studies were carried out and the information fed into this EIA report.

The increase in the demand for sand and gravel for construction and other purposes such as flood control has placed immense pressure on the environment where sand and gravel resources occur. This study was carried out to determine the environmental effects of sand and gravel mining in Luku, North central Nigeria, using field observations and oratory analysis of soil samples.
