Appalachia

During the second quarter of 2013, disposal volumes in the Company's Appalachia region were over 550,000 barrels (BBL) representing an increase of more than 35% compared to the same period last year and an increase of 13% compared to the three months ending March 31, 2013. Volumes of water handled at the Company's New Matamoras barge transloading and bulk storage facility increased 14% compared to the prior period ending March 31. Almost all of the sequential New Matamoras volume increase was comprised of high-solids content fluids that are being processed through the Company's Frac-Cycle® water treatment system.

South Texas

Volumes of water disposed in South Texas increased 56% during the second quarter compared to the three months ending March 31, 2013. Disposal activities at the company's Dilley salt water disposal (SWD) facility accounted for almost 73% of the South Texas volumes during the 2nd quarter.

Oklahoma

Oklahoma disposal volumes decreased over 60% during the second quarter 2013. As previously announced, a lightning strike and fire during April caused one of our primary SWD wells to become inoperable. The Company is continuing to negotiate with the two insurance companies for settlement of this claim which exceeds $1 million.

Management Comments

Commenting on second quarter operations, Jonathan D. Hoopes, Interim-CEO, President and COO of GreenHunter Resources, said, "We were pleased to see a reversal in the weather-related slowdown that we experienced during the first quarter in the Appalachia region. GreenHunter's Frac-Cycle® services, which carry substantially higher gross margin as compared to SWD injection, are now fully operational and we are looking forward to assisting upstream E&P companies treat their complex high-solid water. The Dilley SWD in South Texas remains a very good performer and we are seeing strong interest for increased volumes from our existing Eagle Ford customers that we hope to satisfy with the acquisition of additional new rolling stock. At present, GreenHunter Water owns twelve UIC Class II commercial disposal wells, ten of which are currently operational."
