The Choptank and Patuxent tributaries of Chesapeake Bay have become eutrophic over the last 50-100 years. Systematic monitoring of nutrient inputs began in similar to 1970, and there have been 2-5-fold increases in nitrogen (N) and phosphor-us (P) inputs during 1970-2004 due to sewage discharges, fertilizer applications, atmospheric deposition, and changes in land use.

Assessment of sewage and septic derived nitrogen in the Choptank and Patuxent Rivers

Jones AB, Dennison WC and Pantus F ·
1 December 2003

An assessment of nitrogen sources to the Choptank and Patuxent River (including Island Creek), was conducted during the summer of 2003. Results demonstrated that both rivers were compromised with sewage derived nutrients. An Ecosystem Health Index for defined reporting regions was calculated from a variety of ecosystem heath parameters and then converted to a report card grade from A+ to D- and F for fail (Table 1).
