Water treatment has been an important and often overlooked component of the hydraulic fracturing process. Currently, the primary method of hydraulic fracturing flowback water disposal is deep underground injection into caverns using EPA Class II disposal methods. There is an urgent need for new methods of removing total dissolved solids (TDS) from hydraulic fracturing flowback water. Affordable and environmentally friendly methods should be a high priority as to preserve our drinking water and fragile ecosystem. Our research explores the structure activity relationships of pyridine-based small molecules that can bind and sequester metals in water, in addition to the capabilities of the small molecule:metal complex to be used as a source of nutrition by bacterial found in soil.
