Your comment about the bay is on target. Sandy Point beach gets closed quite frequently because of
the fecal stuff floating in the bay.

I did not have much luck finding current WQ numbers on the web. There
are some numbers on the Fairfax County site referring to the Wilson
Bridge project but they are aimed at nutrients, turbidity and DO, not
coliforms.
The DO numbers are pretty dismal tho (2s and low 3s). That will limit
the types of fish that can live there. They did not specify a time of
day but if these are not done at dawn, the number will be higher than
the accepted standard monitoring protocol would give you.

I have an Email in to the Potomac Riverkeepers organization to see
what they can tell me.

Most of the problems with the Potomac in the 60's and 70's was due to
Blue Plains. Even today they are a major cause of problems in the
Potomac.

They are talking about nitrogen and phosphorus, (nutrients).
Those are tough on DO but it is not what closes beaches and makes
people sick. When they look at swimmer safety they look at coliforms.
Blue Plains shoots enough chlorine into the effluent that it would be
safe to drink if you could get over the yuck factor. When I was there
they did have a plant manager take a big drink on TV.
This is still down river of DC. It would not affect people up there.
I would worry more about street runoff if I fell in the water at the
14th street bridge. The Anacostia has it's own unique problems with
industrial pollution that you don't see on the west side.

Blue Plains was constantly letting untreated waste into the rivers.
There are no good swimming areas above Haynes Point and most of the
fishing for eating is down below Alexandria.

Yup, after a heavy rain, one should not be drinking the water in either the Anacostia or Potomac
rivers. One shouldn't be drinking water out of the Chesapeake either. But, the Blue Plains
discharges of untreated water aren't quite 'constant'.

That CSO in Rock Creek sort of shoots the hell out of thinking Haines
Point is so safe.
It sounds like Blue Plains isn't even most of the problem. They have
52 other direct dump sites.
It also shows why South East is the source of most of the trash. They
have a separate storm water system that bypasses the treatment plant.
If a can goes in a storm drain in Anacostia, it ends up in the river.
If you tossed a can in the storm drain in Chevy Chase, it would end up
in the sewer system.

I live up near the Gaithersburg, Maryland airport (GAI) and this is
where the Rock Creek begins. Rock Creek runs from close to my house all
the way down through the county through DC and into the the Potomac
River in Georgetown. That is quite a bit of run-off area to pull from
that goes straight into the bay. When you check the storm drains you see
them painted with the words empties into Chesapeake Bay or something
similar.
