| the effect of the new massachusetts bay sewage outfall on the concentrations of metals and bacterial spores in nearby bottom and suspended sediments. | since the new outfall for boston's treated sewage effluent began operation on september 6, 2000, no change has been observed in concentrations of silver or clostridium perfringens spores (an ecologically benign tracer of sewage), in bottom sediments at a site 2.5 km west of the outfall. in suspended sediment samples collected with a time-series sediment trap located 1.3 km south of the outfall, silver and c. perfringens spores increased by 38% and 103%, respectively, in post-outfall samples whil ... | 2002 | 12474967 |
| are toxic contaminants accumulating in massachusetts coastal sediments following startup of the massachusetts bay outfall: a comprehensive comparison of baseline and post-diversion periods. | the massachusetts water resources authority (mwra) conducts monitoring to address concerns related to the 2000 diversion of secondarily treated effluent discharge into massachusetts bay. baseline data (1992-2000) showed multiple regions defined by physical and chemical composition. near the massachusetts bay outfall, there is a series of heterogeneous sediments in relatively close proximity to the primary historic source of contaminants (boston harbor). farfield sediments exhibited greater compo ... | 2006 | 16806283 |
