CRWA strives to improve water quality in the Charles River watershed, increase water quantity through groundwater recharge, and reduce stream temperatures, bank erosion, and flooding. Through CRWA’s Blue Cities Initiative, we’ve learned that integrating land use and water resource management is critical to river health. To restore the natural environment in urbanized areas, we must not only utilize low impact development approaches that recharge groundwater and increase streamflow, but also reduce phosphorus loads from entering the Charles.
Through extensive scientific research, CRWA has developed nutrient and phosphorus limits for the Charles River which are among the most protective in the country. Armed with this knowledge, CRWA persuaded the U.S. Environmental Protection Agency to expand new stormwater regulation to owners of highly impervious commercial, industrial and high density residential lots in the upper Charles River, in an effort to help meet water quality standards.
CRWA also works to strengthen existing environmental laws, regulations, and polices, as well as implement them around the Charles River watershed and beyond. Additionally, CRWA often partners with other environmental advocates to defeat measures in the state legislature that if passed, would weaken environmental protections.
