Copy and paste is not permitted and will not be tolerated in this module. An example of how to answer this question is as follows: Groundwater quality is not affected by chemical, biological, and thermal pollution from point and non-point sources. False: Groundwater quality is also affected by chemical, biological, and thermal pollution from point and non-point sources. 2.1 To limit the formation of sinkholes in a dolomitic area, point release of water is preferable. 2.2. In a scenario where dust creation leads to bad air quality, the dust is the aspect and the air quality is the cause. 2.3 Rainwater should be allowed to flow away as quickly as possible, thus preventing erosion. 2.4 Before construction takes place, all Red Data plants or communities must be identified and protected by providing demarcation, to prevent access to them. 2.5 To prevent contamination of sub-surface water, septic tanks, and soak-away sewerage systems must not be used in sandy soils, in areas with a high water table. 2.6 Large trees should be used for shaded parking on a construction site. 2.7 Sedimentation traps below stream crossings will reduce sedimentation lower down the stream. 2.8 Greywater from mines containing chemicals regardless of their composition should be used to contain dust on internal mining roads. 2.9 Noise from a development can be mitigated during the operational phase by removing all speed bumps and stop streets to ensure that traffic does not generate noise, as the breaking and speeding of vehicles generate noise. 2.10 To safeguard a construction site, lights around the perimeter should brightly illuminate the entire area around the site to timeously detect perpetrators. (10x2=20) QUESTION 3 Provide your own opinion, supported by information gathered in environmental science books or peer-reviewed journals. Answer the following questions: [10] 3.1. In your view, what is environmental impact assessment (EIA), and what is its purpose? Support your answer with information from reliable sources on the internet, or legislature (i.e. Acts, policies, etc). Do not copy-and-paste and reference your sources used correctly. Do not use Wikipedia or any source where opinions are not researched or peer-reviewed. Provide a list of the sources used in a reference list. Use only the Havard referencing style, for the in-text and and reference list/bibliography. (5) 3.2. Using practical examples of your choice, discuss impact identification methods for EIA. Use only the Havard referencing style, in-text and provide a reference list/bibliography of all materials cited in your answers.
