MEMORANDUM
To: . Wilmington Regional Complaint Files, Onslow County
From: Stephanie Garrett, Environmental Senior Technician
Subject: Water Quality Complaint on White Oak River
BIMS incident # 201101845
The Wilmington Regional Office received a complaint on June 7, regarding water quality concerns in the
White Oak River near Belgrade, downstream from the Martin Marietta quarry. Michael Banks, owner of White
Oak River Outfitters, was concerned that the river appeared to be devoid of life below the mine. He also
reported a strong .sulfur smell in the area, conditions he believed began sometime in September or October
after flooding from a tropical system.
Stephanie Garrett and Linda Willis responded to the complaint on July 201h, which involved an
inspection of the mine and physical and chemical monitoring on the river (Figure 1). Roughly a mile of the river
is incorporated into the old mine, and functions more as a lake system, until the river exits the mine. Steve
Whitt, a Martin Marietta employee reported that floodwaters inundated the mine after Tropical Storm Nichole
produced over twenty inches of rain in four days last September. The mine recorded 31.5" of rainfall from
September 27 through the 301h
Physical measurements for temperature, conductivity, pH, dissolved oxygen (DO) were taken at all five
locations (BEL-1 through BEL-5, Figures 1-5) and are shown in Table 1, Figures 2 - 7. Samples were collected for
a variety of parameters at stations BEL-1 through BEL-4, and included: fecal coliform bacteria, nutrients,
sulfate, and sulfide. Not all parameters were sampled at all stations. Results are shown in Table 1.
Mine operations appeared to be within permit requirements and they were also found to be compliant
in 2002, 2005 and 2009. All physical parameters were within normal range and did not exceed water quality
standards (Table 1), where prese6t. nductivity w slightly elevated at all locations; water temperatures
were lower than typical July levels; DO was very good at all locations, although was slightly elevated in the'lake
indicating phytoplankton activity; and pH was within normal range. Only two of the chemical parameters (fecal
coliform and sulfate) have water quality standards, and both appeared to be well within normal, acceptable
ranges. No sulfides were detected. Nutrient levels were within normal ranges at the bridge station (BEL-2) and
in the discharge from the mine (BEL-4). Nitrate/nitrite and phosphorous levels were high at the Maysville outfall
(BEL-4) and in the river near the stormwater outfall, roughly 300 feet below the Maysville WWTP. These high
levels are likely primarily from the wastewater plant, although there is a fair amount of agriculture in the
watershed.
Mr. Banksiconcerns about a sulfur odor last October was not something that could be investigated due
to the fact it was several months ago, although both sulfate and sulfur samples were collected. It is likely that
the sulfur odor he reported was a result of the flushing of anoxic bottom sediments in back waters and a result
of the decomposition process of all the debris that was washed into the river during Tropical Storm Nicole last
September. When a hurricane or tropical storm brings significant rainfall, substantial amounts of organic debris
is washed into area streams, and stagnant, low oxygen back waters and sediments are flushed out.

Decomposition of leaves and other organic debris is a multistage process, resulting from pia variety of
microorganisms. Initially, bacteria that thrive in an oxygen rich environment, break down and digest the organic
debris, and In the process utilize the oxygen that is present in the water. This creates a significant demand on
oxygen levels, and eventually results in a substantial drop in available oxygen, typically within a few days of
heavy rainfall. Because the aerobic microorganisms can no longer survive, anaerobic decomposition (without
oxygen) processes begin. The final stage of this process involves methane -producing bacteria, which can result
in strong odors. Additionally, anaerobic bottom sediments are inhabited by a variety of bacteria, one of which
produces hydrogen sulfide. When sediments from stagnant backwaters are flushed out, the sulfur producing
bacteria are introduced into flood waters, adding to the odor. This is a normal cycle during abnormally high
rainfall events, such as hurricanes and tropical systems, and odors may last for several days. Oxygen levels do
recover, but may take several weeks or more to get back to normal levels, depending on the severity of the
storm event.
Mr. Banks was also concerned that the river below the mine was "devoid of life". It is beyond the scope
of a water quality investigation to conduct fish or wildlife surveys, but we did see a couple gar swimming near
the landing off Dixon Farm road. It is important to note that fish kills or "evacuation" by fish of low oxygen
waters are also very common after significant storm events. It may also take a substantial amount of time for
the biological community to reestablish itself to normal levels. Justin Homan, a fisheries biologist with the
North Carolina Wildlife Resources Commission, does sampling on the White Oak River and can be contacted for
further information on fish populations at 252-746-6739. No further action is anticipated. However, Hurricane
Irene made landfall August 26th-271h and dropped over 10 inches of rain in the northeastern portions of the
state. Oxygen levels have again dropped, fish kills and foul odors are being experienced in many surface waters.
Staff are monitoring oxygen levels in the region and anticipate it will take several weeks or more for recovery.
