1. What is the accepted definition of a ‘contaminated site’? Broadly discuss the reasoning underlying the definition and discuss reasons why there are notifiable activities and what these activities are. What other government or supply authorities are required to be notified for development work to be initiated? HD question – How might groundwater be a significant issue on this site? Definition of a contaminated site To understand what a contaminated site is, soil contamination should be defined to understand the scope of contamination that can affect a site when observed in a construction context. Soil contamination can be loosely defined as polluted soil, thereby including liquid or solid hazardous substances mixed amongst the earth’s naturally occurring soil causing impurity. The causes of soil contamination can range from negligence, intentional abuse or at times unintentional actions that can all lead to destructive consequences with long term affects. Soil contamination in Australia is commonly caused through a chemical interference with pesticides, metals such as lead, chromium, cadmium and mercury, petroleum and solvents. The following List outline key causes of soil contamination: ï‚ § Unintended Spills ï‚ § Acid rain ï‚ § Rigorous farming ï‚ § Deforestation ï‚ § Genetically modified plants ï‚ § Nuclear wastes ï‚ § Industrial Accidents ï‚ § Landfill and illegal dumping ï‚ § Agricultural practices, such as application of pesticides, herbicides and fertilizers ï‚ § Mining and other industries ï‚ § Oil and fuel dumping ï‚ § Buried wastes ï‚ § Disposal of coal ash ï‚ § Drainage of contaminated surface water into the soil ï‚ § Discharging urine and fasces in the open ï‚ § Electronic waste The Queensland Government, Department of Environment and Heritage, Protection, de... ...ivide by two as we know the ground is flat in the zone where we need to fill we therefore do not average. B = Height variance to fill level x the distance B = 3*14.584 B = 43.752 Notes: 1. The distance of 14.584 meters is chosen assuming that the chosen shape has right angles in B C and D. 2. We don’t need to divide by two as we know the ground is flat in the zone where we need to fill we therefore do not average. C = height varian to fill level x the distance C = 3*14.584 C = 43.752 Note1: We don’t need to divide by two as we know the ground is flat in the zone where we need to fill we therefore do not average. Prismoidal Formula Application Volume = (A+4B+C)*L/6 V = [30.468 + (4*43.752) + 43.752] * 30.118 / 6 V = (30.468 + 175.008 + 43.752)] * 30.118 / 6 V = (249.228 * 30.118) / 6 V = 7506.249 / 6 V = 1251.041 m ³ Environmental engineer
