Welcome! Here's what's new at MyRWA...



6/28/2015 - The City of Cambridge has issued an advisory that Combined Sewer Overflow (CSO) CAM401B has discharged to Alewife Brook within the last 48 hours. During heavy or prolonged rain events, CSOs can discharge stormwater mixed with untreated sewage.Discharges from CSOs contain levels of bacteria, viruses, raw sewage and other pollutants that may pose health risks to people who come in direct or indirect contact (e.g. contact with pets swimming in contaminated water). Contact with CSO-contaminated water should be avoided. Read more about Combined Sewer Overflows on our website here.

What’s happening to carp in the Mystic?

Many big carp have died recently on the Mystic. We have reported the event to state agencies and had conversations with fish experts.   The state experts' best understanding of this is that it is a natural die off resulting from stresses from spawning in combination with some environmental factor (changes in water temperature, bacteria or virus that specifically affects carp, etc.).  We do not think this is related to pollution. For more information see our blog post.
