DESCRIPTION:Stephen R. Hutchins, Ph.D., Research Environmental Scientist; 
 USEPA National Risk Management Research Laboratory, Ground Water & Ecosys
 tems Restoration Division, Robert S. Kerr Environmental Resarch Center; 9
 19 Kerr Research Drive, Ada, OK.\nAn overview of several projects will be
  presented on a research program currently underway at ORD’s Ground Wat
 er and Ecosystems Restoration Division (GWERD) to evaluate CAFO impacts o
 n ground water quality. The overall research objectives are to characteri
 ze the potential for ground water impact from a variety of stressors asso
 ciated with different types of CAFOs, to develop tools to determine sourc
 es and specific mechanisms of impact, and to then collectively use these 
 data to develop effective risk management strategies for protection of gr
 ound and surface water quality. Initial specific research objectives were
  to evaluate selected swine CAFO operations to understand which stressors
  pose the greatest risk for transport into ground water under site operat
 ing conditions. Much of the work initially focused on the field site at C
 anton, Oklahoma, which demonstrated that land application of liquid swine
  waste led to ground water contamination by nitrate. Stable nitrogen isot
 ope data were found to be useful in helping to identify the source. Other
  stressors, such as estrogen hormones (which are endocrine-disrupting che
 micals) and antibiotics, were not detected in ground water at that site. 
 However, estrogens, as well as nitrate and ammonia, were found in ground 
 water at another site which had been directly impacted by a leaking lagoo
 n. Based on these studies, secondary research objectives have been identi
 fied and research is in progress to 1) expand the current efforts to incl
 ude other types of CAFOs, 2) further develop analytical tools for detecti
 on of estrogen conjugates, 3) expand the use of stable isotope tools for 
 source tracking of nitrate, and 4) evaluate the effectiveness of Nutrient
  Management Plans (NMPs). A survey of swine, poultry, dairy, and beef fee
 dlot lagoons has recently been completed and will be discussed, with emph
 asis on estrogens and estrogen conjugates. Other ongoing projects that wi
 ll be briefly described will include the Regional Applied Research Effort
  (RARE) projects that have been established through EPA Regions 4 and 6 w
 ith USDA and USGS to conduct research on stable isotopes and NMP effectiv
 eness, and an Interagency Agreement (IAG) with USDA to conduct an extensi
 ve study on NMP effectiveness.
