Nine Miles Out



Graves Light is the outermost lighthouse in Boston Harbor. Nine and a half miles is the distance of the outfall tunnel and pipework from the Deer Island Wastewater Treatment Plant. Over 2 million residents from Quincy and 42 other cities and towns in the Boston area rely on this efficient engineering marvel. The ocean has water depths of 100 feet or more here. By looking at this beautiful scene you wouldn't know that not far from here, over 50 diffusers release the treated wastewater into the ocean.

what an iconic scene this is. it's hard to connect it to the modern waste-water treatment facility.

Summer Attraction

This tiger swallowtail butterfly was a delight to see pollinating the phlox bed along my driveway.
