What does the future hold for water and wastewater management in Onslow County?
About 30 people gathered at Jacksonville City Hall Thursday night
for insight on that particular topic at a forum hosted by The New River
Roundtable.
The forum featured presenters from the Division of Water Quality,
East Carolina University and McKim and Creed Engineering who discussed
options for the county including water refuse options, aquifer storage
and recovery, wetlands augmentation and emerging technologies.
Scott Shuford, director of Onslow County Planning, said the
challenges facing the county are its increasing population, which in
turn increases water demand and wastewater generation. He said a lack
of initiatives to promote viability of farming could lead to
agricultural lands being converted for other uses. Between 2002 and
2007 the county lost 13 percent of its farmlands. This can increase
impervious surfaces and promote more runoff and reduce recharge.
Impending climate change, such as a rise in the sea level and higher
temperatures for longer periods of time, may also affect the quantity
and quality of the county’s water supply, he said. Threats also include
saltwater intrusion, droughts and additional runoff due to high
intensity storms.
Robert Rubin, senior environmental specialist with McKim and Creed,
provided information on planning for the use of reclaimed water.
“I believe it will be a part of everybody’s water management
future,” he said. “Populations are going to grow. We’ve got to find
ways of supplying water to those people all the time.”
The benefits of water reuse are preserving and extending existing
water resources, comprehensive drought mitigation, improvement in
overall utility reliability, reduction of pollutant discharge into the
environment and creation of an additional revenue base, Rubin said.
Reuse is not “toilet to tap” but instead about using water “beneficially in the community,” he said.
“We can treat, we can disinfect, we can monitor the water … to assure that the reuse program is safe and effective,” he said.
John Dorney, with the division of water quality, said wetlands augmentation is also an option for wastewater disposal.
In Brunswick and Pamlico counties, upwards of 50 percent of their wetlands are viable for wastewater discharge.
“A large percentage of wetlands in the state could be used for this,” Dorney said.
Dorney said wetlands at Emerald Isle Woods already receive storm
water with monitoring requirements. There is an effort underway to
modify existing non-discharge rules to make wetlands augmentation more
feasible which could be adopted as early as 2010.
Richard Spruill, an associate professor of hydrogeology at ECU,
presented an overview of groundwater and geology in Onslow County and
discussed alternatives for reuse through aquifer storage. Options
include surface wastewater irrigation, cooling towers and underground
injection, among others.
While Spruill isn’t opposed to the injection of waste water into
aquifers, he said he wasn’t sure there was enough information on the
subject to do so “intelligently” right now.
“We have the technology … but do we have the intestinal fortitude?” he asked.
Panelists representing Onslow Water and Sewer Authority, New River
Foundation, City of Jacksonville, White Oak New Riverkeeper and Camp
Lejeune weighed in on the information presented.
Frank Sanders, engineering director at ONWASA, said the organization
is interested in wetlands augmentation and is looking into wetlands in
the areas of Holly Ridge and Richlands.
White Oak-New Riverkeeper Tess Sanders said while the organization
is in favor of reuse as part of “good water management” they are
opposed to the storage of treated waste water in aquifers.
“Reuse is appropriate for things such as washing your car and
watering your lawn, but it’s not appropriate for drinking water,” she
said.
Jacksonville resident William Blaha attended the forum. He was most concerned about the future of the Castle Hayne aquifer.
“How long are we going to have that source? Are we going to be able
to freely pump it out … or should we take some steps to preserve some
of that?” he asked. “(I) think we’ve been a little liberal with our
water use and discharge permitting in the community.”
Sneads Ferry resident Bob Bryant said he enjoyed the forum but said
he’s unsure of the place aquifer storage of wastewater has in Onslow
County.
“I think we’re a long way in Onslow County from being able to utilize that technology,” he said.
