BASELINE MONITORING
Since July 2000, MyRWA has been monitoring trends in water quality with the help of a dedicated corps of volunteers. Water samples are collected from fifteen sites across the watershed (see map and site list below) and are analyzed for:
- Enterococcus or E. coli
- total suspended solids
- nutrients: nitrate-nitrite, total phosphorus
- conductivity
- dissolved oxygen
- water temperature
- water color and odor
In 2007, MyRWA released the first Mystic River Baseline Index, which is a summary of water quality from 2001-2007 and describes current conditions in the watershed based on the results of baseline monitoring. The map below shows the location of all baseline monitoring stations. Detailed station descriptions, along with GPS coordinates, are included in the map by clicking on the individual site pointers.
