What is the impact of agriculture on ,wastewater, generation? Agriculture is the single largest user of water, it uses an estimated 70 per cent of total global fresh water, returning the majority of this water back to the system.The daily drinking water requirement per person is 2–4 litres, but it takes 2 000 to 5 000 litres of water to produce one person’s daily food.

monitoring is required in the low parts per billion (µgL–1) to parts per trillion (ng L–1) range. Analysis of contaminants in wastewater at these low concentra-tions is difficult due to the complex composition of wastewater. Therefore, analytical techniques used to deter-mine trace contaminants in wastewater

By recovering metals from ,wastewater, in a pure form, they can be recycled within the manufacturing process or sold to generate revenue to offset treatment costs. Furthermore, treating so-called 'bleed streams' in this way allows for the recycling of the effluent decreasing the need for fresh water and chemicals such as ,acid,, caustic, etc.
