Throughout the year, MyRWA staff and volunteers collect samples as part of more intensive sub-watershed studies through the Hot-Spot Monitoring Program.  Samples may be collected along the entire length of a tributary, or from suspicious stormwater outfall pipes that discharge to the watershed's rivers and streams.  These samples may be analyzed for bacteria, dissolved oxygen, total suspended solids, surfactants, and ammonia.  

The Hot-Spot Program has several goals:

  • Identify sources of sewage contamination

  • Document water quality conditions in tributaries to the Mystic River

  • Monitor stormwater outfall pipes

  • Compare water quality in dry and wet weather



Data reports, tables, and maps are available for download once they have been subjected to a rigorous review process.
