Issues 2002 Harbor Survey Report Showing Cleaner Waterways And Wildlife
Resurgence
Harbor
Water Quality improved by 98 Percent in Last 30 Years
DEP
To Participate In 18th Annual International Coastal Cleanup On Saturday,
September 20.
Hundreds of volunteers visit city beaches to collect and document debris
along coastal shores.
Commissioner Christopher O. Ward of the New York City Department of Environmental
Protection (DEP) announced today that the agency has issued its annual
New York Harbor Water Quality Report. The 2002 report is the 93rd in the
series, and describes improvements in harbor water quality realized through
investments in critical infrastructure and better management of the City’s
sewage and sewage treatment systems. The Report is available on the DEP
website at www.nyc.gov/dep.
Commissioner Ward also noted that DEP will join the American Littoral
Society (ALS) this Saturday to encourage New Yorkers to join in the effort
to voluntarily clean up New York’s shorelines and beaches. The beach
cleanup is part of a global Coastal Cleanup, For more information or to

contains a list of beach cleanup sites at www.alsnyc.org.
Commissioner Ward said, “The massive efforts of the City and environmental
groups such as the American Littoral Society, have helped to significantly
improve the City’s water environment to the point where clean coasts,
open swimming locales, and sightings of wildlife have come to be accepted
rather than seen as rarities as they were in the past.“
“Additionally,” continued Commissioner Ward, “water
quality in New York Harbor is the best it’s been in decades, showing
significant declines in pollutants and increases in dissolved oxygen,”
said Commissioner Ward. Even ignoring the scientific data, the anecdotal
evidence is abundant from the vast number of waterfowl breeding in the
area, to increased populations of bottom-dwelling organisms, to the fact
that beach closures have been virtually eliminated. We’re winning
the battle for the overall Harbor, but there’s still work to be
done. The next battlegrounds are inner harbor waterways in close proximity
to local properties and sewage outfalls that become overloaded during
heavy storms -- places such as Flushing Bay in Queens, Paerdegat Basin
in Brooklyn and other parts of Jamaica Bay. This is where we need to concentrate
our future efforts, even as we reap the benefits of decades of investment
in the Harbor as a whole.”
The 2002 Report notes that fecal coliform levels – an indicator
of the presence of raw or partially treated sewage and one of the most
important water quality indicators – dropped by over 98 percent
in the Inner Harbor and Upper East River since the early 1970s. The trend
coincides with upgrades to the four sewage treatment plants that serve
those areas: Bowery Bay, Tallman Island, Hunts Point and Wards Island.
Other reasons for improvements include better monitoring and control of
industrial discharges and the abatement of illegal dumping into the sewer
system.
The Report also details the problems associated with combined sewer
overflows (CSOs), or the discharge of untreated wastewater during rainstorms
and periods of heavy snow melting. Better management of the sewer system
and capital improvements have increased the capture of overflow at sewage
treatment plants from 18 percent to 62 percent over the last 13 years.
In fact, the DEP has developed a series of Best Management Practices which
have been largely adopted by the federal EPA as the standard for all communities
with CSO problems.
The DEP has also identified 36 CSO abatement projects, totaling over
$500 million. These vary from the construction of massive underground
storage tanks near Flushing Bay and Paerdegat Basin to the deployment
of booms and nets in canals and creeks near 23 other CSO outfalls. The
DEP uses skimmer boats in the Harbor to collect floating trash and debris
from CSOs and storm sewers, and collected over 400 tons of material this
way in 2002 on just its largest skimmer vessel, the Cormorant.
Another pollution control program listed in the 2002 Report restricts
the discharge of certain types of industrial waste into the sewer system.
Over the last 12 years, the number of firms regulated under this program
has increased from 1,000 to 30,000, with no increase in DEP staff. During
that time, heavy metals in wastewater has dropped from 7,800 lbs. to 2,800
lbs. per day citywide. Heavy industry now accounts for less than one percent
of the metals in untreated sewage citywide.
In 1998, the DEP initiated a program to eliminate the discharge of untreated
sewage into the Harbor during dry weather. This program involved a detailed
evaluation of the City’s entire 425 miles of shoreline and over
3,000 sewer outfalls. The initial survey found that there was over 3 million
gallons a day of untreated sewage being dumped into the Harbor daily.
To date, the DEP has eliminated 96 percent of these discharges.
In 1997, the DEP began its annual Enhanced Beach Protection Program
to decrease dry weather sewage discharges though better surveillance and
improved preventive maintenance. As part of this effort, 92 sewage pumping
stations throughout the City have had computerized monitoring equipment
installed. As a result, the total amount of untreated sewage bypassed
from pump stations and regulators during the 2002 season was just 0.0002
percent of total dry weather flow, a 97 percent decrease from the previous
year.
“Some of the main benefits to New Yorkers of all this work and
investment is that all public beaches in the City have been open for bathing
since 1992, and wet weather swimming advisories have been lifted at all
but three of these beaches,” said Commissioner Ward. “Shore
birds have returned to breed in several parts of the Harbor, and fish
and shellfish restrictions have been relaxed.”
Spotlight
on Jamaica Bay
The 2002 Report reflects a special interest in Jamaica Bay, one of the
few areas in the Harbor with persistent water quality issues, and features
the critical estuary in a special section. The Report notes that the flow
of natural streams into the Bay is negligible compared to the discharge
from four sewage treatment plants and numerous CSOs in the area, and that
the nature of the Bay has been altered dramatically by dredging and other
construction projects that have changed the natural flow of water in the
Bay and have effectively isolated certain sections.
Among the findings about Jamaica Bay are:
-
Only 25 percent of the Bay’s original 16,000 acres of wetlands
remain. From 1900 to 1970 nearly 100 million cubic meters of sediment
were dredged from the Bay to fill shoreline marshlands, including
for JFK Airport;
-
Over 350 species of birds have been spotted at the Bay, and the
Bay supports 49 species of finfish, as well as numerous shellfish
and invertebrates and a thriving eel population;
-
Dissolved oxygen levels have been broadly supportive of aquatic
species for the last 30 years and have shown improvement over time;
-
Dissolved oxygen levels remain a concern in the deeper waters of
the Bay, with some spots being out of compliance with State standards
numerous times each year;
-
Fecal coliform levels have decreased by about 80 percent since the
early 1970s, though problem spots continue to exist in contained water
bodies such as Bergen Basin and Sheepshead Bay;
-
Jamaica Bay has the highest level of algae activity in the New York
Harbor region, and has two significant algae blooms each year, from
Feb. to March and a smaller one from June to July. The rise in phytoplankton
growth has been dramatic and may be indicative of eutrophic conditions;
-
Water clarity in the Bay has been declining over the past 16 years,
in part because of the increased algae levels.
“The Harbor Survey Program provides the longest documented assessment
of the impact of human activities on the City’s water,” said
Commissioner Ward. “By sampling at 53 stations and measuring more
than a dozen water quality parameters throughout the Harbor, the survey
identifies trends and changes and provides a unique database for scientists
and educators.”
