Why parts of the Sound where hypoxia is worst have low transfer efficiency rates of nitrogen pollution discharge from wastewater treatment plantsJan 3rd, 2014 | By Environmental Headlines -- CT environmental news
When you look at the map of transfer efficiencies, you notice that the efficiency generally gets higher from east to west, and from north to south.
Wastewater treatment plants closer to Western LIS and the Narrows, where hypoxia is worst, have the highest transfer efficiencies, which makes sense.
But some of the biggest plants which discharge into LIS are those serving New York City, which when combined, discharge just over 1,000,000,000 (yes, one billion) gallons of treated sewage per day. By volume of discharge and total nitrogen load, the impact of these plants dwarfs the impact of surrounding facilities.
