Cape Cod Bay is part of the Gulf of Maine, which is home to a rich ecosystem of wetlands, bird and animal habitats, such as turtles and shellfish, as well as commercially valuable fish stocks. According to the Center for Coastal Studies, it takes about a month for the waters of the bay to completely drain and refill. This has allowed toxic levels of nitrogen to build up. The main source (approximately 80%) comes from septic systems, augmented by fertilizer runoff and other forms of pollutants from nearby parking lots. This excess nitrogen (eutrophication), is linked to toxic algal blooms and depleted oxygen levels (hypoxia). Research into the problem is ongoing, with a plan to mitigate some of the damage through the introduction of a sewer system.
