This is a shocking situation. Massive sludge overapplication. The state
knows about it.
Now there is groundwater contamination...and the City doesn't want to
remediate.
A similar situation exists outside Barstow California, where sewer wastes
were overapplied and didn't have the required permits from San Bernardino
County. Now there is nitrate contamination of groundwater there, too.
Sludge spreading can cause huge environmental and health damages. There
needs to be a stop to putting these contaminated wastes on farm soils.
Enforcement of environmental regulations is a start, since cities are
polluting with impunity.

Raleigh wants cleanup waiver
Faces $80 million bill in sewage mess
Wade Rawlins, Staff Writer
Pollution from treated sewage would leak for decades into the Neuse River
under a plan the city of Raleigh wants the state to approve.
Raleigh officials are asking for a waiver from state rules that would
require an $80 million cleanup of widespread groundwater contamination
around its Neuse River sewage-treatment plant. The city argues essentially
that time and nature will eventually scrub the fields and groundwater of
pollutants.
For years, workers at the plant spread too much treated waste sludge on farm
fields around the plant, despite warnings from the state. The city was
eventually fined and ordered to develop a cleanup plan. Now, the groundwater
beneath more than 1,100 acres of fields is contaminated with high levels of
nitrates, which can harm humans and trigger fish kills downstream near the
coast.
Since the problem came to a head in 2002, the state suspended the city's
permit to spread more sludge on the fields. The city has spent more than $40
million improving the operation of the plant and has turned a higher
proportion of the plant's sludge into fertilizer and compost. Some treated
waste is trucked to Duplin and Sampson counties and spread on farms there.
But city officials say ringing the entire site in southeastern Wake County
with hundreds of wells to collect and treat the groundwater would cause a
financial hardship, costing nearly $80 million.
Instead, city leaders propose to spend about $8 million to build 40 recovery
wells. That would clean up 20 acres nearest housing subdivisions close to
the plant.
The city wants natural degradation to gradually clean up the areas where
monitoring wells show the highest concentrations of nitrogen -- amounts up
to 18 times the maximum allowed under state law. Some of those fields border
the Neuse River.
City officials say the approach poses no risk to public health because
nearby residents have been hooked to municipal water and the contamination
will be monitored. High levels of nitrates in drinking water can be toxic to
infants, who have undeveloped digestive systems that can't break down the
pollutants. As a result, oxygen levels fall in the blood, leading to a
condition known as blue baby syndrome.
"There is no public health impact for spending tens of millions of dollars
on a remediation system," said Steve Levitas, a lawyer representing the
city.
But some residents near the spray fields say the city is skirting state
environmental standards.
"They were issued a permit, and along with that permit came a lot of rules
and regulations about how they should conduct their business," said Phillip
Douglas, a retired electronics engineer who lives near the plant. "One of
the rules prohibits natural attenuation, which means letting nature clean up
your mess. When they messed up and found out how much money it's going to
cost to clean it up, they want a variance."
Douglas, who opposes the city's plan, said state regulators should be the
guardians of the state's water quality and should not take cost into
account.
The state Division of Water Quality is taking public comments through Oct. 5
on the city's request for the waiver from state rules. The state
Environmental Management Commission, a 19-member panel appointed by the
governor and legislative leaders, is expected to hear Raleigh's request in
November.
City's rationale
Raleigh contends its plan would keep it below its limit for nitrogen
discharge into the river. It has sharply reduced its nitrogen discharges in
the past decade, so it has unused discharge capacity. Jay Zimmerman,
regional supervisor for the state's aquifer protection section, said the
city's approach has technical merit because of the practical complications
of trying to remove groundwater from the overall site.
"The way I have explained it is if they were discharging 500,000 pounds of
nitrogen into the river, whether or not it was the right thing for the
river, they would be in compliance with their permit," Zimmerman said.
"We're not saying it's the best choice."
He said the city had not considered another alternative -- to clean up the
most contaminated areas in addition to the areas near subdivisions.
Dean Naujoks, the Upper Neuse Riverkeeper, an environmental advocate, said
state environmental regulators should not give the city a waiver because the
pollution will harm the river.
"Raleigh's groundwater pollution contributes more nitrogen per year to the
Neuse River than the towns of Apex, Benson, Butner, Cary, Clayton, Wake
Forest and Zebulon combined," Naujoks said, noting that Johnston County
could be added in, too, and Raleigh would still be the leading nitrogen
polluter. "The bottom line is they should be required to offset their
nitrogen pollution that is entering the river from contaminated
groundwater."
In addition to being harmful to infants, nitrogen causes excessive algae
growth, which can rob the water of oxygen as it dies and cause fish kills,
hampering sport and commercial fishing. The Neuse has shown stress
downstream from too much nitrogen-rich treated sewage and fertilizer runoff
from farms.
Since massive fish kills in the 1990s, which led to the Neuse's being
classified as sensitive to nitrogen, state environmental officials have
tried to reduce the amount of nitrogen entering the river from
sewage-treatment plants and farming by 30 percent. The city of Raleigh has
sharply reduced its nitrogen discharge into the river.
"We don't like to have any more nitrogen in the Neuse than we can help,"
said Walter B. Hartman Jr., city manager of New Bern, which is near the
stretch of the river where fish kills have historically occurred. "We're not
throwing stones. We just need to take a close look at it -- make sure there
is not a better way."
