Baltimore City's century old infrastructure is constantly releases sewage into the surrounding waterways especially during high rain events. Not only does it cause the water to be unsafe to touch, it provides food for algae and causes blooms which produce "dead zones" affecting the populations of the Bay's animals. Increased algae also affects the water clarity negatively stunting the growth of the Bay's underwater grasses. meridithsandherr https://padlet.com/ccambardella/vxmsnhlft5pxeals/wish/1485019231 Sources:

A goal was set for 2020 to be the year that fishing and swimming in the harbor could be safe. It looks as though the date needs an extension. This article is relevant to my students because they could learn that seafood can carry toxins and that it is not always safe to eat fish just because you catch them. Personally I need to learn more about where the crabs we eat are caught. It is time for me to ask more questions... ]]> 2021-05-03 20:53:56 UTC https://padlet.com/ccambardella/vxmsnhlft5pxeals/wish/1487247792 AVTEX pollution bjames211999 https://padlet.com/ccambardella/vxmsnhlft5pxeals/wish/1494211839 The largest Rayon producer was illegally dumping PCB's into the Shenandoah River causing a spike in pollution and toxic chemicals.  It was later shut down after it continually violated dumping order and continued polluting the water.  The interesting part is Virginia shifting their policy from "working with troubled companies to keep jobs, to shutting down and fining the company". This was a massive step in the right direction.  My question is why did they allow ANY company to dump anything directly into a river?  I fell with all of the known contaminants flowing into the bay from run off or agriculture, why allow companies even access to direct dumping.
