�To reach goal of 15 ppb, both external and internal sources must be
addressed
–External sources - to reduce the amount of new phosphorus that enters the lake each year
–Sediment release - to reduce internal phosphorus cycling
Phosphorus Model: Implications and Conclusions
So, the take home point is
that in order to reach the goal of achieving a phosphorus concentration of
15ppb, both external and internal sources must be addressed.
It is important to address
external sources to reduce the amount of new phosphorus that enters the lake
each year.This can be done by
taking measures such as improving buffer strips, maintaining roads and newer
septic systems and replacing older systems when necessary.
Sediment release must also
be addressed, to reduce the amount of internal phosphorus cycling that
occurs year after year, especially since this accounts for nearly half of
the total amount of phosphorus within China Lake.
Next, Ethan is going to
talk about different methods that can be used to do this.
