A University of Delaware-led study finds that the U.S. Environmental Protection Agency (EPA) has significantly overestimated the poultry’s industry’s contributions to water pollution in the Delmarva Peninsula.
Researchers tell the Delaware News Journal that the multi-state study, involving thousands of manure tests, discovered that actual nitrogen levels in poultry-house manure are 55 percent lower than EPA’s decades-old, lab-based standards.
According to a meatingplace.com report, the study could force changes to cleanup efforts in the poultry-rich region. A formal proposal for changes to the Chesapeake Bay Program’s six-state pollution forecasting model could come as early as next month. That model is used to guide a federally backed attempt to restore the bay’s health and ecosystems.
The EPA’s efforts to control water pollution in the Delmarva are thought to be a model for possible future federal programs in the Mississippi River watershed.
