"Overall health" in that article probably refers to nutrient contamination and low DO numbers, not necessarily the various coliforms that are unhealthy to people. When I get a minute I will look at the test numbers and see what they are talking about. Usually we start looking at coliforms when the colony count gets over 200 or so. If it is enterococcus you really want it under 35. The whole damned bay ain't really "pure". ;-( Badmouthing is a thing some folks do out jealousy or childish spite. Best to disregard it.

I've canoed there, along thousands of other people. Looks clean? Are you really that stupid? |

The higher level of industrial pollution is coming from North East DC and near in Maryland, simply because they don't have that kind of development in North West. They also say most of the trash is coming down the storm drain system. It could be an indication that people in NE/SE are more likely to sit on the corner and drink. They don't have the nice patios that the people in North West have ;-) That explains it. And the DC government folks pocket so much of the city's income that the city can' put trash cans on the corners and empty them. |

There are no good swimming areas above Haynes Point and most of the fishing for eating is down below Alexandria. *Way* down below Alexandria, if at all. Fin fish are not really much of a problem if you are just talking about sewer pollution. The things you have to worry about in fish are the heavy metals and some other organic chemicals that can settle in the muscle tissue. That is persistent pollution and it will be in the water forever, all the way to the bay and ocean. (only being diluted) Clams and oysters are the ones that collect coliforms. OTOH when the DO gets as low as they were measuring at the sites I looked at (2.5 - 3), you are only going to catch trash fish that can live in a low oxygen environment. Part of the treatment process is oxygenating the water so Blue Plains might actually help the fish near the discharge. It doesn't take long until the nutrients and the problem that causes to eat all of the oxygen tho. The other number you want to see in reference to that is chlorophyll. Somebody up there must be running a full panel of water quality measurements but I can't find it. Not enough info here? http://www.vdh.state.va.us/epidemiol...lthtoxicology/ |

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. http://www.cbf.org/page.aspx?pid=406 |
