Though usually not a factor in the health of an estuary, phosphorus can contribute to estuarine blooms and low oxygen under some circumstances.
In the September, 2018, issue of Interstate Waters, James Ammerman describes the conditions and dynamics that make phosphorus worth watching by policy makers and estuary managers.
Ammerman is the science coordinator for the Long Island Sound Study.
Phosphorus and nitrogen from fertilizer and wastewater plants feed blooms that deplete oxygen and threaten aquatic life.
Generally, phosphorus is only significant in bodies of fresh water.
Also in the magazine, NEIWPCC looks back on fifty years of wastewater training, and catches up with Alexandra Dunn, the administrator of EPA Region 1.
Appointed early this year, Dunn told NEIWPCC that in the Northeast, the debate about environmental protection is “rarely whether. It’s just how.”
Another story explores how, fifty years ago, NEIWPCC launched its first training program for plant operators as states and municipalities were building new wastewater plants, .
The early efforts forestalled a shortage of qualified operators. Today, NEIWPCC trains thousands of operators and operator candidates a year across the Northeast.
The September issue also reports news from clean-water programs around the region and describes the status of federal issues of concern to NEIWPCC.
