Memorandum of Agreement between U of A and ADEQ This specifies the agreement for the study to be done by the University on C & H Hog Farm which was funded by the state. (See U of A Monitoring Proposal below)

 University of Arkansas Monitoring Proposal and Workplan This is the proposal by U of A for a $340,000 project to monitor C & H Hog Farm. This is a 1-year proposal but an additional 4 years of monitoring is recommended at an estimated cost of $100,000 per year. This proposal was approved by the legislature on Sept. 5, 2013 to be paid out of "Rainy Day Funds".
2nd Coalition Letter to ADEQ from Karst Geologist Brahana  This is a continuation of the letter below requesting C&H Hog Farm is unsuitable for this CAFO, urges immediate revocation of the permit, and a study of the specific Karst geology from the CAFO to the Buffalo National River.

The Role of Phosphorus Management - Dr. Andrew Sharpley - January 30, 2015 Youtube presentation from Maryland Phosphorus Symposium. Quote from approximately 32;00: "We can't expect cheap food and clean water at the same time."

Arkansas Act 369 (see Sections 13-14), enacted March 6, 2015.  This appropriations act provides an additional $100,000 per year for 4 years for continued support of BCRET, bringing the total amount of taxpayer-support for monitoring this privately owned industrial facility to $740,000.

 Electrical Resistivity Imaging (ERI)

BCRET and the U of A School of Agriculture contracted with Dr Todd Halihan of Oklahoma State University to conduct and ERI study on three fields at C&H. Dr Halihan also conducted additional studies around the waste holding ponds in March, 2015. These subsurface imaging studies revealed what was described as a "possible major fracture and movement of waste" beneath the ponds. However, BCRET declined to investigate further and only through FOIA requests did BRWA discover news of this possible leakage in January, 2016.


Memorandum of Agreement between University of Arkansas and Oklahoma State University for ERI study

Preliminary ERI Surveys of Mt Judea Alluvial Sites  This report of work done in Dec. 2014 by Oklahoma State University on behalf of BCRET reveals karst features beneath 2 fields being studied. Of note: "The bedrock at each site contained potential pathways for groundwater flow. One difference between the sites that may be useful for application evaluation is the possibility of hog manure electrical signatures present on Field 12."
