BOOK AND PAGE OF DEED IN TO THAT PARTY]
NOTICE IS HEREBY GIVEN THAT: The New Hampshire Department of Environmental Services
(Department) has issued Groundwater Management Permit #GWP-_________-A-001
(“Permit”) to [Permittee]. Pursuant to Env-Or 607.09(a) this notice is recorded for each
property located within the groundwater management zone identified in the Permit at the
Registry of Deeds for the county in which the property is located.
The Permit establishes a Groundwater Management Zone (“GMZ”), an area within which
groundwater use must be controlled and monitored due to the presence of groundwater
contaminants that exceed the State’s Ambient Groundwater Quality Standards (“AGQS”).
The Permit may include conditions to and restrictions upon the use of the properties within
the GMZ, including restrictions on the use of groundwater.
The Permit was issued on [Date] and expires on [Date], unless renewed for subsequent five-year
period(s). This Notice will remain in effect until such time as the AGQS are restored within
the GMZ and the Department issues a Release of Recordation to the Permittee. The Permit is
available for review at the New Hampshire Department of Environmental Services, 29 Hazen
Drive, Concord, NH 03301 or can be viewed by searching under our OneStop Data Retrieval

Low-Level Ethylene
Dibromide (EDB)
Screening Program Update
Kenneth Richards, P.G.
NH Department of Environmental

Low-Level Ethylene
Dibromide (EDB)
Screening Program Update
Kenneth Richards, P.G.
NH Department of Environmental
Services
Ethylene Dibromide (EDB)
Also known as 1,2-dibromomethane and numerous
trade names and acronyms
Used in the past as a leaded gas additive (phased
out in 1985) and soil fumigant (banned in 1984) for
crops and turf (golf courses). Also as a solvent,
waterproofing agent, in dyes & pharmaceuticals
Still used in aviation and racing fuels and chemical
formulations
Released to the environment by leaded gasoline
spills and land applications as a pesticide
Ethylene Dibromide (EDB)
(cont.)
EDB is a volatile organic compound (VOC) and is
included on the U.S. EPA SW-846 Method 8260 list
of analytes
The Method 8260 detection limit for EDB in
relatively clean samples is generally 0.5 – 1.0 ug/l
The Federal Maximum Contaminant Level (MCL)
and New Hampshire AGQS for EDB is 0.05 ug/l
Program Goals
Identify EDB presence/absence at NH Sites
Identify potential EDB impacts to drinking water
wells
Provide basis to formulate modified monitoring
programs at identified EDB sites to include lowlevel EDB analysis
Site & Sampling Point Selection
Release sites with known gasoline storage in
1985 or earlier
Sampling points selected along transect of
contaminant plume
In general, samples collected from one source
area well, one mid-plume well & one distal well
Analytical Methods For Low-Level
EDB Detection
US EPA SW-846 Method 8011
US EPA SW-846 Method 504.1
US EPA SW-846 Method 8260 SIM
(Selective Ion Method)
Preliminary Results
200 sites during Spring, 2008 groundwater
sampling rounds; 700 groundwater samples
analyzed
EDB positively detected at 15% of sites sampled
Detections ranged up to 650 ug/l
45% of the EDB detections were <1.0 ug/l
Preliminary Results (cont.)
EDB detections primarily found at sampling
points within or immediately downgradient of
source areas
EDB not identified in water supply wells
included in program
U.S. EPA LNAPL Screening Study
EPA analyzed LNAPL collected from 28 older
release sites in 8 states
DES coordinated the submittal of 23 LNAPL
samples from 8 NH sites
EDB identified in LNAPL samples from 4 of the
8 NH sites
EDB detected at levels ranging from 0.15mg/l to
255.28 mg/l
Path Forward
Second round of low-level EDB screening to be
conducted during the Fall 2008 groundwater
sampling rounds
DES has been requesting field pH measurements
on wells included in Fall screening round
Individual EDB site strategy should be developed
in consultation with DES project managers

Laboratory
1,4-Dioxane
• MW=88.11
• Density=1.03
• BP=101.1
• Soluble in water
Available Methods
• EPA Method 8260B (C)
– Purge and Trap-GC/MS
• EPA Method 8270C (D)
– Liquid/Liquid Extraction-GC/MS
• EPA Method 8261A
– Vacuum Distillation-GC/MS
EPA Method 8260
• In order to meet low level reporting limits
on the order of 3 ppb, must make
modifications
• Heat sample during purge cycle (80-90 oC)
• Acquire data in SIM Acquisition Mode
• Use 1,4-dioxane-d8 as an internal or
surrogate standard
EPA Method 8270C
• Extract 1L of water
• Concentrate Extract
• Use Isotope Dilution (1,4-dioxane-d8)
• Acquire data in SIM Acquisition Mode
EPA Method 8261A
• Sample is placed in a distillation chamber
• The chamber is placed under vacuum
• The vapor is passed through a chilled coil
at 5 oC to condense the water
• The uncondensed distillate is cryogenically
trapped at -196 oC (liquid nitrogen temp)
• Analytes transferred to GC/MS
EPA Method 8260B Advantages
• Most labs familiar with P&T technique
• Minimal sample prep
• Automation possible
• Can achieve reporting limits 2-5 ppb
EPA Method 8260B Disadvantages
• 1,4-Dioxane has poor purging efficiency,
can be compensated for by heated purge
and isotope dilution
• If Method not managed correctly can
encounter problems with carry over or
poor reproducibility
Method 8270C Advantages
• Most labs familiar with technique
• Can achieve reporting limits 1-3 ppb
• Modified to use isotope dilution
Method 8270C Disadvantages
• Possible losses during extraction
procedure
• Possible losses during collection and
transport (samples collected with
headspace)
• Labor intensive for some labs
EPA Method 8261 Advantages
• Easily achieve 1-2 ppb reporting limit
• Potential for sub-ppb reporting limits with
SIM
• Minimal sample prep
• Isotope dilution is standard procedure
Method 8261A Disadvantages
• New Technique
• Not common for most labs
• Only 1 Instrument Manufacturer
• Requires liquid nitrogen
• Cost of equipment and operation

Health Effects of 1,4 Dioxane
Group B2 carcinogen:
“. . . reasonably anticipated to be a human
carcinogen”
Cancer of gall bladder, lungs, skin, and liver
in laboratory mice.
Drinking Water Standards for
1,4-Dioxane
EPA IRIS: 1x10-6 cancer risk – 3 ppb
EPA Regions 3 & 6 screening level – 6.1 ppb
State cleanup guidelines – 3 to 85 ppb
World Health Organization – 50 ppb (10-5 cancer
risk)
NH AGQS – 3 ppb
NJ – 3 ppb
Conn, Vt – 20 ppb
Maine – 32 ppb (10-5 cancer risk)
Mass – GW-1 of 3 ppb
Presence of 1,4 Dioxane
Superfund Sites:
Keefe (Epping) – Max. conc. of 842 ppb
In Mar. 2004 present in 28 of 35 wells
Ottati & Goss (Kingston) – Max. conc. 260 ppb
Presence of 1,4 Dioxane (cont.)
Likely present in wastewater discharges (0.25
mg/person/day = 1 ppb)
Landfill leachate –
Colebrook - 98 ppb; in 21 of 34 wells
Newmarket - 610 ppb; in 22 of 29 wells
Newport 240 ppb; in 6 of 9 wells
Hopkinton - 14 ppb; in 3 of 8 wells
Groundwater in Tokyo – 0.05 to 113 ppb, avg.
2.23 ppb
Tama River in Japan 0.06 to 5 ppb (likely due to
flow from WWTF)
1,4-Dioxane At Haz. Waste Sites
1,1,1-TCA AGQS – 200 ppb
2-8% 1,4-dioxane in TCA
Dioxane could be controlling contaminant at
TCA site (3 ppb vs. 200 ppb)
TCA breaks down to 1,1-DCA or 1,1-DCE
DCA could be primary contaminant w/o TCA
& dioxane be present & controlling
Dioxane Sampling Requirements
New haz. waste sites after Jan. 30, 2008
Sites receiving new GWMP in 2008
GWMPs where public/ private wells sampled
GWMPs or sampling programs where dioxane
is an identified analyte
Haz waste sites w/ TCA, DCA, or DCE present
Haz waste sites, salvage yards, landfills after
Jan.1, 2009
Waiver of sampling w/ 2 rounds ND
Remediation for 1,4-Dioxane
SVE for removal from soil but . . .
Biodegradation in presence of THF
GAC generally inappropriate
Air stripping poor due to low Henry’s Law
coef. but does work (47% and 28% removal
Colebrook, 65% removal Hadco)
AOP appears best process
Ozone/peroxide
Peroxide and UV light
Remediation for 1,4-Dioxane (cont.)
Air sparging is ineffective
Zero-valent iron walls don’t work
ISCO has worked
H2O2 plus ozone
Fenton’s reagent
Permanganate
Persulfate
Ozone alone
Phytoremediation effective
1,4 Dioxane Summary
Highly mobile, recalcitrant compound
Present at many haz. waste sites
Likely present at active & inactive landfills
Low AGQS
May be controlling contaminant at some sites
Can be treated in-situ by ISCO and ex-situ by
AOP
Additional sampling results beginning 2009
will help define extent of this contaminant
