Environmental Issues

Inhabited by people for thousands of years, and industrialized for 375 years, it’s not a surprise that Neponset River Watershed has its share of environmental issues, including:


Climate Change

Climate change affects Neponset land, water, people and wildlife, changing what we view as “normal.” Species adapt to these changes, migrate elsewhere, or deal with the consequences. We can reduce our contribution to climate change as well as help natural communities to adapt.


Dams

Old dams on the river and its tributaries degrade water quality and aquatic environments, block fish movement, hinder human recreation, and can threaten public health.


Exotic, Invasive Species

Plant, animal, insect, and fungi species can be categorized as “native,” “exotic,” a hybrid of the two, “naturalized,” or “invasive.” As such, they have different effects on the surrounding environment.


Food Advisory: Fish

If you fish in freshwater and eat your catch, it’s important to keep up to date on the Freshwater Fish Consumption Advisory List, published by the MA Department of Health. Decide whether to eat your catch based on the pollutants in the fish.


Stormwater Runoff

This is the rain water or snow melt that picks up pollution from hard, impervious surfaces, such as roads, parking lots and driveways, and washes into our waterways, usually via storm drains.


Threats to Aquatic Habitat

Pollutants; low water levels; direct removal of habitat; disturbance of vegetation and soil at the water’s edge; exotic, invasive species; acid precipitation; obstructions (dams); and degradation of fish spawning habitat all impact the watershed.


In addition, there are problems with:

  • Legacy Toxins – For example, PCB-laced soil and groundwater from a former industrial property that leaches toxins into the river.
  • Low Water Levels – Drought affect our river, its tributaries, our groundwater, ponds, lakes and wetlands, especially during the summer.
  • Sewage Contamination – This may happen when a building’s stream of wastewater is connected to the wrong piping system, and thus flows into the river as opposed to a water treatment facility).
  • Significantly Altered Ecosystems
