October 2020 Water Quality Report (CWMN)
Moderate rainfall leads to above-average October water pollution
June 2020 Water Quality Report (CWMN)
Data collection continues as water quality takes a typical June decline.
May 2020 Water Quality Report (CWMN)
We continue to collect valuable water quality data in compliance with COVID-19 restrictions by implementing enhanced safety procedures to keep our volunteers and staff safe.
Neponset River 2019 Water Quality Summary
Overall, it's a mixed outlook for the Neponset River, with outstanding dissolved oxygen, mediocre total phosphorus, and worsening E. coli levels.
September 2019 CWMN Report
The Neponset River makes a comeback with better E. coli, Phosphorus, and Dissolved Oxygen levels in September.
There’s no such thing as the poop fairy
It's a year round problem. Dog waste that's left on the ground can lead to serious water pollution issues.
October CWMN Update
We ended the sampling year on a strong note!
July and August 2018 CWMN Update
Rainy weather contributed to high E. coli concentrations this summer.
June 2018 CWMN Update
The June results are a bit worse than they were in May, but overall not terrible.
CWMN Results: June
The results for June show much higher E. coli levels than were observed in May. This is mainly because June was a wetter month than May, and bacteria levels in wet weather are typically higher than levels in dry weather.
CWMN Results: May 2017
The water sampling results are in and the findings are encouraging. Kudos to the Norwood DPW for the progress they've made toward a healthier Meadow Brook.
Water Quality Data – October 2016
The 2016 Citizen Water Monitoring Network (CWMN) season wrapped up on Wednesday, October 13.
Water Quality Data – September 2016
Impacts of the drought include unusually high bacteria levels and dangerously low dissolved oxygen levels.
Water Pollution Hot Spots: Fall Update
We've resolved six hot spots in total and hope to resolve more before our first season is over.
Water Quality Data – August 2016
The majority of our CWMN volunteers managed to get samples for August, despite drought-induced low water levels throughout the Watershed.
Water Quality Data – July 2016
This month, bacteria levels were higher than usual, despite the extremely dry weather and low water levels.
Water Quality Data – June 2016
The June Citizen Water Monitoring Network (CWMN) sampling event took place on Thursday, June 16. By coincidence, this happened to be the morning after a fire on Hawes Brook resulted in a fish kill involving hundreds of fish, the results of which are discussed later in this post. Our volunteers collaborated to sample 41 different […]
Water Quality Data – May 2016
The first Citizen Water Monitoring Network (CWMN) sampling event of the year took place on Thursday, May 19. Our volunteers helped to sample from 41 different sites within the Neponset Watershed, and the below map illustrates the bacteria results we received. Red and orange dots on this map indicate areas along the watershed that are not safe […]
New Efforts to Clean up Unquity Brook in Milton
NepRWA aims to discover the source of bacteria in Unquity Brook by using a newly developed technology called Microbial Source Tracking.
A New Look at Unquity Brook
Water quality issues have been noted for some time along Unquity Brook; new funding will allow for further investigation.
