Hydraulic fracturing, also known as “fracking”, produces large amounts of contaminated water in addition to the extracted petroleum.  A possible solution for degradation of these contaminants is photocatalysis. The focus of this study was using a photocatalytic method for degradation of glutaraldehyde, a biocide commonly used in fracking water.  A compound parabolic array containing porous poly(methyl methacrylate)/TiO<sub>2</sub> composite materials was used to treat a 20 L aqueous solution of 120 ppm glutaraldehyde.  After 26 h of solar exposure, the concentration of glutaraldehyde was reduced to 3.7 ppm.  This photocatalytic system shows promise for the purification of fracking wastewater pending further experiments involving increasingly complex aqueous matrices.<br/>
