RE: APPROVAL WITH MODIFICATIONS

FWDA FACILITY-WIDE GROUNDWATER

PERIODIC MONITORING REPORT, JANUARY THROUGH JUNE 2013

FORT WINGATE DEPOT ACTIVITY,

EPA ID# NM6213820974

FWDA-13-009

Dear Messrs. Patterson and Smith:
The New Mexico Environment Department (NMED) has completed its review ofthe U.S.
Department ofthe Army's (the Permittee) Fort Wingate Depot Activity (FWDA) Groundwater
Periodic Monitoring Report, January through June 2013, (Report) dated September 2013. This
submittal is a requirement ofSection V.A.2 ofthe Fort Wingate Depot Activity RCRA Permit
(RCRA Permit). NMED hereby approves this Report with the following modifications. The
Permittee must address the following comments in future reports as directed.
COMMENT I
Reconstruct Figure 1-2 (Site Features - Northern Area) to better display northern area wells.
Well FW31 can be shown as an inset to a larger map showing northern area wells in greater
detail. Other significant features can be labeled on the map such as the administration and
workshop areas. Some parcels are not labeled, such as Parcel 6, and other boundaries need to be
defined such as between Parcel 11 and Parcel 21 . These changes may require the submittal of a

larger map such as those provided with Off-Site Well Periodic Monitoring Reports.
COMMENT?
In Table 4-1 Northern Area Groundwater Elevations (Wells Screened in Alluvial Sediments),
well MW24 is reported with a difference of 8 feet in the readings from January 9, 2013 to April
1, 2013. Verify the accuracy of this data and, if accurate, explain the reason for the drop in
elevation.
COMMENT3
In Section 4.0, Figure 4-3, January 2013 Northern Area Bedrock Groundwater Contour Map,
contours were not drawn for the western wells. Monitoring wells TMW32, TMW38, and
TMW40D also appear miscontoured in this figure. TMW32 also appears incorrectly contoured
in Figure 4-4 (April 2013 Northern Area Bedrock Groundwater Contour Map). Recontour
Figure 4-3 and Figure 4-4 to correctly show groundwater elevations reported.
COMMENT4
In Section 5.1.2 Nitrate and Nitrite of the groundwater analytical results section, the Report
states that nitrate concentrations for this reporting period " ...exceeded the EPA MCL of 10 mg/L
in samples from 11 alluvial monitoring wells in the Northern Area." After reviewing the data in
Table 5-2, 14 alluvial well exceedences were noted. Table 5-1 correctly reflects this also. For
future reports ensure that the text reflects the data for the same reporting period.
COMMENTS
In Section 5.1.4 Perchlorate, page 5-3, lines 13-16, the Report discusses that alluvial and bedrock
groundwater perchlorate contamination coexist and suggests a perchlorate source area is
"upgradient in a recharge area for the bedrock groundwater unit", but does not attempt to identify
source area(s). The same situation exists for the nitrate bedrock plume. Source area identification
is important for both defining contamination extent and successfully rernediating a site. Include
discussion about potential source areas in future Reports.
COMMENT6
In Figure 5-2, April 2013 Northern Area Nitrate and Nitrite Concentrations in Bedrock
Groundwater, the mapped shape of the nitrate plume conflicts with the groundwater elevation
Messrs. Patterson and Smith

maps in Figures 4-3 and 4-4. Additional wells are needed to further delineate the northern part
of the bedrock nitrate plume north of TMW02(89 mg/L). Discuss these findings, and plans to
further delineate this plume.
COMMENT7
In Figure S-4, April 2013 Northern Area Explosives and Perchlorate Concentrations in Bedrock
Groundwater, the extent of the perchlorate plume must be further delineated. More wells are
needed west and northwest ofwell TMW49 (1900 ug'L) and northwest ofTMW40D (280 ug/L).
Make recommendations to further delineate both perchlorate and nitrate plumes.
COMMENTS
In Section 6.2, Recommendations, page 6-2, lines 17-18, the Report recommends to "Suspend
groundwater-sampling activities at monitoring wells containing less than 1 foot of saturated well
screen." List the specific wells where suspension of sampling is recommended. In describing
the wells where sampling would be suspended, present information describing the anticipated
effects on the ongoing investigation and monitoring programs. Recommend replacement of
important wells with deeper wells to fill in significant data gaps.
COMMENT9
Background monitoring well BGMW02 has consistently exceeded the regulatory limit of 10
mg/L for nitrate in the last four sampling events. Discuss this in the groundwater analytical
results Section S.1.2 Nitrate and Nitrite in the next report submittal.
