Ewaste is a problem because it contains many hazardous chemicals like mercury, lead and cadmium which could seep in to the soil and eventually to the groundwater. This would lead to contamination of the drinking water. The most important thing to remember would be to separate this type of waste with the others. It would be better if you sell it or give it for reuse. Also, you can send it to a recycler that knows what to do with these wastes.
