Restoring the Bay Is Imperative to Human Health

There's no denying it: Our environment and our health are intrinsically linked. Clearly, dirty waters are not only unhealthy for the fish, oysters, and crabs that live in them, they are unhealthy for the people who fish, swim, boat, and drink them. The restoration of the Chesapeake Bay and its rivers and streams is vital to the protection of our human health.

Our Drinking Water

Polluted runoff not only causes low oxygen "dead zones" in the Chesapeake, which suffocate marine life such as crabs, oysters, and fish, it can also contaminate private drinking wells. In fact, recent studies found that between 21 and 60 percent of wells tested in Pennsylvania's lower Susquehanna River Basin had nitrate levels exceeding public drinking water standards. Drinking water with too much nitrates can raise the risk of cancer, nervous system deformities in infants, hemorrhaging of the spleen, and other problems.

Our Food

In the Chesapeake region, governments have issued statewide fish-consumption advisories for mercury for all lakes and rivers in Pennsylvania and Maryland, and for many rivers in Virginia. This heavy metal, often released by the burning of coal, pollutes waterways, taints fish, and can potentially damage human intelligence.

Our Air

Coal-fired power plants, like the one proposed in Dendron, Virginia, pose substantial human health risks, such as illnesses, premature deaths, health-related costs and so on. In the U.S., an estimated 20,000 heart attacks and 13,200 premature deaths per year are caused by fine particle pollution from coal-fired power plants. The annual cost of these illnesses and deaths has been estimated between $62 billion and $100 billion, with the toll falling heaviest on children and elderly.

Our Way of Life

The combination of warmer waters, nutrient pollution, animal waste, and sewage contribute to the growth of harmful bacteria in our waters such as Vibrio (a bacteria that can cause life-threatening skin and blood infections and intestinal illnesses), Cyanobacteria (a blue green algae that can cause liver disease, skin rashes, nausea, and vomiting), and Cryptosporidium (a protozoan that can cause gastro-intestinal illness). Nutrient pollution is caused by an excess of nitrogen and phosphorous from many sources, including stormwater runoff from streets, farm fields, barnyards, and lawns; discharges from sewage treatment plants, septic tanks, and industries; and air pollution from power plants, factories, and vehicles.

The Cost of Dirty Water

According to the Journal of Environmental Management, clearly polluted waters can lead to substantial medical costs and lost wages in addition to poor health, such as:

  • $37 (due to lost wages and medical care) for each gastrointestinal illness caused by exposure to polluted recreational marine waters;
  • $38 (due to lost wages and medical care) for each ear ailment caused by exposure to polluted recreational marine waters;
  • And $27 (due to lost wages and medical care) for each eye ailment caused by exposure to polluted recreational marine waters.
