MEMORANDUM
TO: Debra Watts SIZ1..>
FROM: Michael Rogers
RE: Issuance of permit to inject 3-D Microemulsion (3DMe) (Permit #WI0600074)
Robeson County Solid Waste Management Facility
I recommend that Permit Number WI0600074 be issued to Robeson County to inject the above referenced injectant(s) to
remediate groundwater (GW) contaminated with various volatile organic and semi -volatile organic compounds.
SITE DESCRIPTION: The site is an active landfill owned and operated by Robeson County. Evidently, surface water
leaching through the closed unlined phase 1 area of the landfill has resulted in VOCs and SVOCs in the soil and
groundwater (Figure 1).
HYDROGEOLOGIC DESCRIPTION: The site is located in the mid -southern Coastal Plain Geologic province. In the area of
the site, the lithology consists of interbedded sand, and silty and clayey sand. Below these interbedded elastics is a
confining clay layer (Black Creek?) at about 40 feet BLS. Depth to groundwater is dependent upon topographic relief with
a depth of 4.3 feet BLS (11/14/2007) at MW-5, the area of the injection. oundwater flow direction is generally south.
Based upon average velocity of the site, groundwater flows proximate) 21 feet/year igure 2). Hydrogeologic data for
MW-5 indicates a groundwater velocity kf 0.1 feet t per year�d;-
EXTENT OF CONTAMINATION: The leachate plume is not clearly delineated. According to information provided in the
application, there are several private water supply wells within 1/4 mile. However, there is only 1 water supply well identified
downgradient, which is approximately 2800 feet (Figure 3).
PROPOSED INJECTION: This pilot test injection will be via a total of 3 proposed permanently installed injection wells. The
injection is planned to last 1 day and a total of 1000 gallons of injectant will be injected. The estimated percentage of
formation fluid displaced by the injection is approximately 2.6%. Therefore, based upon a groundwater flow velocity of
0.1 feet per year and a 2.6% interstitial void displacement, the potential displacement of the plume is low. The revised
updated location of the injection and monitoring wells plus schematics are presented on the map attached to the additional
information letter received May 26, 2011.
HOW rr WORKS: The Applicant is proposing to use 3DMe, which is the same as HRC Advanced. This product will
remediate groundwater contaminated with volatile and semi -volatile organic compounds via enhanced bioremediation.
MONITORING: A revised map showing the 3 monitoring wells is presented on the earlier referenced additional
information letter. Wells to be monitored during postinjection are highlighted in yellow (existing MW-5 and 2 proposed
new monitoring wells). Sampling frequency will be at pre -injection, then every 2 months for 8 months. It appears that the
applicant will review this data to determine if a full-scale rejection will be beneficial.
EPIDEMIOLOGY: The DHHS has approved the above compound(s) as injectants.
REGIONAL OFFICE COMMENTS: Each of the RO comments/recommendations are discussed below (RO's
comments/recommendations are underlined).
7
A as built survey of the injection well locations, shall be submitted within 60 days after installation and introduction of the
oxidizing materials. I discussed this permit condition with Jim as he always requests this. After showing him that the
requirement to submit maps with the location of the wells is already in the permit in Part VII.4, he agreed that it is not
necessary to include this additional redundant language.
