REMEDIATION Efficacy of sand and soil to prevent leaching of heavy

metals

http://theprepperproject.com/wp-content/uploads/2013/07/DirtBeforeAndAfter.jpg

- 3 sand, 3 soil dishes- 1 mL 27000 ppb lead

nitrate- Samples taken,

analyzed for lead concentration

STUDY: SAND AND SOIL AS RETENTION

MEDIA

Sand retains lead better than soil- Intensity plotted

against radius

- Similar volume samples produced concordant results

- Soil carried a higher concentration of leachate further from contamination site

OUTLOOK●Pond water: significant heavy metal leaching

●Crumb rubber: heavy metal leaching insignificant to human health○Harmful volatile organic

compounds●Sand better at stopping leaching

○Potential use in e-waste facilities
