Eel River is vulnerable to nitrogen pollution.
Algae growth in the
Eel River is limited by limiting how much nitrogen gets into the river. More nitrogen
causes more algae.
entering the groundwater from the Town's new wastewater facility will cause algae and plant growth, choking the river with many tons
of water plants and algae. Ultimately the fish, the wildlife, and
the river itself will die.
Redfield Ratio chart shown below shows the river's sensitivity to
extra nitrogen. The Redfield Ratio is the relationship between inorganic
nitrogen and inorganic phosphorus in the river water.
were taken at several locations at different times of the year. The
sampling locations marked in yellow are downstream from the Plymouth's
new wastewater treatment facility, and will be impacted by nitrogen
discharged into the ground by the facility.
areas colored red or magenta indicate sensitivity to nitrogen pollution,
and the sampling locations downstream from the wastewater plant are
mostly red or magenta.
