Research Idea Scope
Recent study findings where tire shreds were used for lightweight fill in road base construction in a wetland suggest that wrapping the tire shreds with a geotextile fabric could trap heavy metals and organic chemicals within the fabric wrap. The observed trapping could be unique to the groundwater chemistry or geology of the current study site where installed. The results of the current tire shreds study indicate that long term testing of groundwater is required to evaluate the long-term environmental effects of a waste material.
Urgency and Payoff
This study will also determine if the use of geotextile woven fabric is a viable option for trapping heavy metals and/or organic chemicals around the waste material in wetland construction sites or similar extreme wet environments. Retaining chemicals close to the source material lessens the local environmental impacts
