CCWA has been successful in fighting water pollution, but here are some intersting facts about where further effort is
- Codorus Creek has over 447 miles of streams, but only 46% of those assessed meet water quality standards. Nonpoint source
pollution has negatively impacted many of them
- Stream bank and channel erosion and sedimentation is responsible for more than half of the degraded streams. Every stream
and tributary in the watershed has been affected by stormwater runoff.
- Although information is available for less than half of the Codorus Creek's streams and tributaries, many of those are
considered eutrophic (high in nutrients and low in dissolved oxygen).
- The Susquehanna River, which feeds into the Chesapeake Bay, accounts for about 20 percent of the total phosphorus and
39 percent of the total nitrogen loadings of the Bay. Nonpoint sources of pollution generate the majority of these nutrients.
