The effects of water impurities on plant growth


Water impurities generally include minerals, viruses, bacteria and other organic material. Sewer water from homes and industries contain a large variety of such water impurities. Currently, sewer water is going through some initial treatment to remove some impurities and then it is discharged in rivers and oceans. 

If water impurities are not harmful to the plants, part of such water can be used for irrigation and watering gardens. 

 Project description:
In this project you will perform experiments to find out how water impurities affect plant growth. You will start from planting seeds so all your plants will have the same age and conditions. You may optionally expend your experiments to see if plants can affect the impurities in water.
