Boston Groundwater Trust (BGwT) has just completed our ninth and final set of well readings for 2016. We had more rain in the month of October (5.87") than we did in the previous 4 months combined. As a result the majority of the wells were up in this reading set. We need more months like October. As of November 29th we have had just 29.04" of precipitation. This is the least amount we have ever had in the January-November timeframe (see table in the attached November 2016 newsletter files). In our 811 observation well network 16 wells were the highest they have ever been and only 3 wells (compared to 66 wells last reading set) were the lowest they have ever been. Our system average is currently 6.36'.

As for our hotspot areas, levels in the central to western part of Back Bay recovered quite nicely. In particular the area along Beacon and Back Streets bounded by Exeter and Herford streets. BWSC continues to investigate and dye test lines along Beacon, Back, and Fairfield Streets where levels did come up but still remain low. In the South End BWSC relined a sewer at the corner of Appleton & Tremont Street. Thus far we have yet to see a positive on groundwater levels in that area. BWSC investigations along Clarendon Street in the South End continue as well. The remaining areas all saw nice bumps from the rainfall in October.
Attached are the usual color coded well elevation maps for our entire network. I've also attached additional files and have a brief explanation of each below.
