Centuries of strain on our rivers have added up.
Like most New England rivers, the Assabet, Sudbury, and Concord Rivers flow through a landscape that bears the imprint of human activity. Roads, houses, and other human uses of the land affect both the rivers' water quality and their flow. Home to a human population of 413,000 (and growing), the rivers and the aquifers beneath provide both wastewater disposal and water supply for watershed residents and businesses. As the business, industrial, and residential population grows, the demands on the rivers increase, affecting water quality, streamflow, and the ability to support natural plant and animal populations.
