The Scenic Illinois River is currently experiencing high levels of phosphorous that promote eutrophication and impair overall water quality. Recently, the States of Oklahoma and Arkansas have entered into an agreement, Statement of Joint Principles and Actions, to reduce nutrient loadings in the Illinois River Basin. This agreement includes setting NPDES permit limits to an interim (2009) phosphorous limit of 1.0-mg/L, and a proposed final (2012) phosphorous limit of 0.037-mg/L. These stringent phosphorous limits are unprecedented in the region, and many publicly owned treatment works (POTWs) are not equipped to meet them. In addition, it has been questioned whether current technology is capable of reliably meeting phosphorous limits on this order of magnitude.
