1994 CONNECTICUT AMBIENT AIR QUALITY SUMMARY
All of the 11 Ozone (03) sites operating in Connecticut had exceedances of
the 03 NAAQS in 1994. The Greenwich, Middletown and Stratford sites each had
four exceedences of the NAAQS. The Stratford site had the highest second
maximum values of 0.174 ppm or 145 % of the standard. In each of the last three
years ozone levels in Connecticut have been fairly consistent with coastal sites
reporting the largest number of days over the NAAQS.
There were no exceedances or violations of the 1 hour or the 8 hour
NAAQS at any of the 5 Carbon Monoxide (CO) monitoring sites in the state. The
Hartford site reported the highest second maximum 8 hour average of 7.9 ppm or
88% of the NAAQS. The five year trends show that CO levels are relatively
stable.
In 1994 Nitrogen Dioxide (NO 2 ) monitoring was performed at 4 sites. The
photochemical assessment monitoring site (PAMS) in Stafford only operates during
the ozone season and measures background (transport) nitrogen dioxide. The
seasonal arithmetic mean at this site was 15% of the NAAQS. The urban site in
New Haven measured the maximum NO 2 annual average of 30 ug!m 3 or 30 % of
the NAAQS.
There were no exceedances or violations reported at any of the 13 Sulfur
Dioxide (SO 2 ) sites in 1994. The highest annual arithmetic mean was reported in
New Haven at 27 ug/m 3 or 34 % of the NAAQS. Stamford reported the highest
24-hour second maximum of 150 ug/m 3 or 41 % of the standard, as well as, the
highest 3-hour second maximum of 280 ug/m 3 or 22 % of NAAQS. The Mansfield
site reported the lowest 24-hour second maximum of 48 ugfm 3 or 13 % of NAAQS.
At all monitoring locations the SO 2 five year trends did not show any apparent
trends.
10
-------
There were no violations of the quarterly Lead (Pb) NAAQS at any of the
6 sites in Connecticut. Stiles Street in New Haven continued to report the highest
Pb level with a maximum quarterly average of 0.17 uglm 3 or 11 % of the NAAQS.
No other site reported a maximum quarterly average which was above 1 % of the
NAAQS. The five year trend graph shows that Pb levels have continued to
decrease.
None of the 32 Particulate Matter less than 10 Microns (PM 10 ) sites in
Connecticut had exceedances or violations of the annual or 24-hour NAAQS for
PM 10 in 1994. The highest 24 hour values were reported at Norwalk with a
highest second maximum value of 76 ug/m 3 or 51 % of the daily standard. All the
sites were well below the annual NAAQS. The maximum annual average was in
New Haven with a reported concentration of 40 ug/m 3 or 80% of the NAAQS.
The five year trend graphs show no discernable trends for PM 10 , except for the site
on the corner of Stiles Street in New Haven which had reduced PM 10
concentrations in 1994.

1994 MAINE AMBIENT AIR QUALITY SUMMARY
Three of the 12 Ozone (03) sites operating in Maine had exceedances of the
03 NAAQS in 1994. The Ocean Avenue site in York County, the Two Lights
State Park site in Cumberland County and the Navy Road site in Sagadahoc
County each had one exceedences of the NAAQS. The Ocean Avenue and Two
Lights sites had the highest maximum values of 0.148 ppm or 123 % of the
standard. In each of the last three years ozone levels in Maine have been fairly
consistent with 2 or 3 coastal sites reporting 1 or 2 exceedences of the NAAQS.
In 1994 the only Nitrogen Dioxide (NO 2 ) monitoring was at the
photochemical assessment monitoring site (PAMS) at Two Lights State Park in
Cape Elizabeth. This site only operates during the ozone season and measures
background (transport) nitrogen dioxide. The seasonal arithmetic mean at this site
was 4% of the NAAQS.
There were no exceedances or violations reported at any of the 14 Sulfur
Dioxide (SO 2 ) sites in 1994. The highest annual arithmetic mean was reported in
Madawaska at 22 ug/m 3 or 30 % of the NAAQS. Madawaska also reported the
highest 24-hour second maximum of 117 ug/m 3 or 32% of the standard as well
as the highest 3-hour second maximum of 300 ug/m 3 or 23 % of the standard. Two
sites Village Green and Taylor Mountain in Rumford reported the lowest 24-hour
second maximum of 34 ug/m 3 and 37 ug/m 3 or 9% and 10% of the standard. At
urban monitoring locations the SO 2 five year trends do not show any apparent
trends. However, SO 2 levels at several industrial locations in Lincoln and
Millinocket have shown decreases in the last five years.
Because of extremely low Lead (Pb) concentrations at the two Pb monitoring
sites in Maine during the last five years, Maine has discontinued Pb monitoring.
24
-------
None of the 34 Particulate Matter less than 10 Microns (PM sites in
Maine had exceedances or violations of the annual or 24-hour NAAQS for PM 10
in 1994. The highest 24 hour values were reported at the Northeastland Hotel in
Presque Isle with a highest second maximum value of 70 ug/m 3 or 47 % of the
daily standard. All the sites were well below the annual NAAQS. The maximum
annual average was at Tukey’s Bridge in Portland with a reported concentration
of 27 ug/m 3 or 54% of the NAAQS. The five year trend graphs show no
discernable trends for PM 10 , although levels continue to fall in several areas such
as Lincoln and Presque Isle.

1994 MASSACHUSETTS AMBIENT AIR QUALITY SUMMARY
Massachusetts maintains nine carbon monoxide (CO) monitoring sites in the
Commonwealth. Four sites are located in Boston (Kenmore Square, Visconti Street-East
Boston, Breman Street-East Boston; and the Federal Post Office Building), two sites are
each located in Springfield (East Columbus Avenue and Liberty Street) and in Worcester
(Central Street and Franklin Street), and a single site is located in Lowell (Old City Hall).
No exceedance or violation of the one-hour or 8-hour NAAQS for CO was recorded at
any of the Massachusetts CO monitoring sites. In general, however, the maximum one-
hour and 8-hour concentrations of CO increased in 1994 when compared to 1993. The
Kenmore Square-Boston site showed a decline in concentration from 1993 CO
concentrations for the one-hour and eight hour NAAQS, as did the two Worcester sites
(for the 8-hour NAAQS). Yearly variability in CO concentrations is evident from the
recent five year data record (1990-1994), due in part to changes in meteorology and
emission source characteristics. The data, except for those from Springfield, show a
general decrease in the concentration of CO over this period.
Seventeen ozone monitoring sites were operated and maintained during the 1994
summer ozone season. Six monitoring sites recorded ozone concentrations above the
NAAQS for ozone and concentrations recorded during 1994 were generally less than
those recorded in 1993. This may be attributable to the frequent summer thunderstorms
in 1994, and to emission reductions of ozone precursors from mobile, stationary, and
area sources. The highest ozone concentrations were recorded at the Quabbin Summit
(0.132 ppm), Worcester Airport (0.130 ppm), and Lynn (0.130 ppm) monitoring sites.
The other sites, which recorded maximum ozone concentrations above the NAAQS, were
in the Connecticut River Valley at Agawam (0.125 ppm), Amherst (0.125 ppm), and
Chicopee (0.128 ppm). Over the most recent five years the maximum concentration of
ozone and the frequency of concentration in excess of the 03 NAAQS has decreased.
This has been due to changes in the emissions of ozone precursors and changes in
meteorology.
Nitrogen dioxide measurements were made at 13 monitoring sites through out the
Commonwealth. The highest annual average concentrations were recorded in the
Metropolitan Boston area, Worcester, and Springfield. The lowest concentrations were
recorded at the rural sites, Quabbin Summit and Newbury-Plum Island. The Kenmore
Square and Breman Street monitors recorded the highest average annual N02
concentrations, 0.035 ppm and 0.030 ppm respectively. Both rural sites recorded average
annual concentrations of N02 of 0.008 ppm. NO2 concentrations throughout the
Commonwealth were generally similar to those recorded in 1993, although somewhat
higher, with eight monitoring sites recording higher average annual concentrations and
seven sites recording higher one-hour maximum N02 concentrations. Yearly variability
for the Massachusetts average annual N02 data is small and no upward or downward
trend is evident for the sites, over the past five years.
34
-------
Twenty-eight S02 monitoring sites were operated by Massachusetts during 1994.
No exceedance or violation of the annual or 24-hour (primary), nor the 3-hour
(secondary) NAAQS for S02 was recorded. The highest short-term (3-hour) S02
concentrations were recorded at the Swansea monitoring site (686 ug/m3 and 358 ug/m3
for the 1st and 2nd maximum 3-hour concentrations), two sites in Fall River, and the
Quabbin Summit site which also recorded the highest 24-hour concentrations of S02 (220
ug/m3 and 183 ug/m3 for the 1st and second maximum 24-hour concentrations). It was
unusual for this rural site to measure such high concentrations of S02. It is noteworthy
that these concentrations all occurred at the end of March and the begining of April, and
that N02 concentrations were also somewhat elevated, indicative of possible transport
from one or more local combustion sources. As in previous years, however, the Quabbin
Summit site recorded the lowest annual average S02 concentration (11 uglm3). The
highest annual S02 concentrations were recorded in Boston (Kenmore Square -29 ug/m3,
Breman Street - 25 ug/m3, and three other sites) and in Worcester (Central Street - 22
uglm3). Except for the Worcester site, which measured higher concentrations of S02
in 1994, almost all of the S02 monitoring sites show a small decline in S02
concentrations over 1993 and a general decline in S02 concentrations over the past five
years.
Massachusetts maintains four lead monitoring sites, two each in Boston and
Springfield. During 1994 maximum lead concentrations at all sites were at or below 0.01
ug/m3, well below the national standard. These concentrations were less than 1 % of the
NAAQS for lead. Concentrations of lead in the ambient air continue to decrease.
There are eighteen (18) PM1O monitoring sites in Massachusetts. With the
exception of the Quabbin Summit and Sudbury sites, all of the sites are located within
urban areas of the Commonwealth. The highest annual average concentrations of PM1O
were recorded in Springfield (32 ug/m3), Boston-Charlestown (29 ug/m3), and Boston-
Kenmore Sq. (28 ugfm3). The highest maximum and second highest maximum 24-hour
PM 10 concentrations were recorded at East Springfield (97 ug/m3 and 54 ug/m3), Boston
(Columbus Avenue-92 ug/m3 and 54 ug/m3 and Charlestown-65 ug/m3 and 58 ug/m3),
and Springfield (East Columbus Avenue-8 1 ug/m3 and 68 ug/m3 and Howard Street-7 1
ug/m3 and 55 ug/m3). In contrast the lowest average annual concentrations were
recorded at Sudbury (13 ug/m3 and at the Quabbin Summit (12 ug/m3). Over the past
five years the concentrations of PM 10 at the urban sites have recorded a lot of data
variability. The Boston-Charlestown and Worcester sites have shown a general
downward trend in PM1O concentrations. The other sites, excluding the non-urban sites
have shown significant year to-year variability with no apparent upward or downward
trend visible. The Quabbin Summit site has shown a general reduction in the average
annual concentration of PM 10.

1994 NEW HAMPSHIRE AMBIENT AIR QUALITY SUMMARY
Only 2 of the 7 Ozone (03) sites operating in New Hampshire had one
exceedance of the 03 NAAQS in 1994. Both the Portsmouth and Rye Harbor sites
reported the highest daily maximum values of 0.135 ppm or 113 % of the standard.
Last year only Rye Harbor reported an exceedance. In 1992 there were no site in
New Hampshire reporting any exceedances.
In 1994 Nitrogen Dioxide (NO 2 ) monitoring was performed at 2 sites. The
site in Manchester measured the maximum NO 2 annual average of 15 ug/m 3 or
15% of the NAAQS.
There were no exceedances or violations of the 1 hour at any of the 2
Carbon Monoxide (CO) monitoring sites in the state. The Nashua site reported an
exceedance of the 8 hour NAAQS. The highest second maximum 8 hour average
at Nashua was 9.2 ppm or 102% of the NAAQS. The five year trends show that
CO levels are relatively stable.
There were no exceedances or violations reported at any of the 11 Sulfur
Dioxide (SO 2 ) sites in 1994. The highest annual arithmetic mean was reported in
Keene and Pembroke at 20 ug/m 3 or 25 % of the NAAQS. Pembroke also reported
the highest 24-hour second maximum of 168 ug/m 3 or 46% of the standard, as
well as, the highest 3-hour second maximum of 485 ug/m 3 or 37% of NAAQS.
The SO 2 five year data showed no significant trends.
There were no violations of the quarterly Lead (Pb) NAAQS at any of the
5 sites in New Hampshire. Keene and Portsmouth reported the highest Pb level
with a maximum quarterly average of 0.02 ug/m 3 or 1.5 % of the NAAQS. No
other site reported a maximum quarterly average which was above 1 % of the
NAAQS. The five year trend graph shows that Pb levels continue to be at the
lowest levels of method detection.
None of the 14 Particulate Matter less than 10 Microns (PM 10 ) sites in New
Hampshire had exceedances or violations of the annual or 24-hour NAAQS for
PM 10 in 1994. The highest 24 hour values were reported at Berlin with a highest
second maximum value of 71 ug/m 3 or 47% of the daily standard. All the sites
were well below the annual NAAQS. The maximum annual average was in Berlin
with a reported concentration of 32 ug/m 3 or 64 % of the NAAQS. The five year
trend graphs show no discernable trends for PM 10 .

1994 RHODE ISLAND AMBIENT AIR QUALITY SUMMARY
All of the 3 Ozone (03) sites operating in Rhode Island had one exceedance
of the 03 NAAQS in 1994. The Alton Jones site reported the highest daily
maximum values of 0.152 ppm or 127% of the standard. In each of the last three
years ozone levels in Rhode Island have been fairly consistent.
In 1994 Nitrogen Dioxide (NO 2 ) monitoring was performed at 2 sites. The
photochemical assessment monitoring site (PAMS) in East Providence only
operates during the ozone season and measures background (transport) nitrogen
dioxide. The seasonal arithmetic mean at this site was 12 % of the NAAQS. The
urban site in Providence measured the maximum NO 2 annual average of 22 ug/m 3
or 22 % of the NAAQS.
There were no exceedances or violations of the 1 hour or the 8 hour
NAAQS at any of the 3 Carbon Monoxide (CO) monitoring sites in the state. The
Dorrance Street in Providence reported the highest second maximum 8 hour
average of 6.7 ppm or 74% of the NAAQS. The five year trends show that CO
levels are relatively stable.
There were no exceedances or violations reported at any of the 3 Sulfur
Dioxide (SO 2 ) sites in 1994. The highest annual arithmetic mean was reported in
Providence at 24 ug/m 3 or 30% of the NAAQS. Providence also reported the
highest 24-hour second maximum of 97 ug/m 3 or 27 % of the standard, as well as,
the highest 3-hour second maximum of 198 ug/m 3 or 15% of NAAQS. The SO 2
five year data showed a slight downward trend.
Because of extremely low Lead (Pb) concentrations at the Pb monitoring
sites in Rhode Island during the last five years, Rhode Island has discontinued Pb
monitoring.
58
-------
None of the 8 Particulate Matter less than 10 Microns (PM 10 ) sites in Rhode
Island had exceedances or violations of the annual or 24-hour NAAQS for PM 10
in 1994. The highest 24 hour values were reported at Providence with a highest
second maximum value of 70 ug/m 3 or 47% of the daily standard. All the sites
were well below the annual NAAQS. The maximum annual average was in
Providence with a reported concentration of 37 ug/m 3 or 74 % of the NAAQS.
The five year trend graphs show no discernable trends for PM 10 .

1994 VERMONT AMBIENT AIR QUALITY SUMMARY
None of the two ozone monitoring sites in Vermont recorded one-hour
concentrations of ozone in excess of the NAAQS. The highest concentration of
ozone, 0.101 ppm, was recorded at the Bennington site. The highest recorded
concentration of ozone at the Proctor Maple Research site was 0.097 ppm.
Vermont has recorded only one exceedance of the 1- hour ozone standard since
1988.
Vermont operates two nitrogen dioxide (N02) monitoring sites in the state.
One is located in Rutland and the other is located in Burlington. No exceedance
of the NAAQS for N02 was recorded at either site. Historical data for the most
recent five years (1990-1994) indicate that the annual average concentrations of
N02 have remained relatively stable. The Rutland site ranged from 0.012 ppm
N02 to 0.015 ppm N02, and the Burlington site ranged from 0.016 ppm N02 to
0.018 ppm N02. The maximum one-hour concentration of N02, 0.087 ppm, was
recorded at Burlington, Winooski Avenue monitoring site.
The monitoring sites at Burlington and Rutland also measure sulfur dioxide
(S02). No exceedance or violation of the NAAQS for sulfur dioxide was recorded
at either site. The highest 24-hour average concentration of S02, 190 ug/m3, was
recorded at the Rutland site. This site also recorded the highest one-hour
concentration, 456 ug/m3 S02. In contrast, the Burlington site recorded a
maximum 24-hour average concentration of 50 ug/m3 and a one hour maximum
concentration of 81 ug/m3 S02. Five years (1990-1994) of historical S02 data
indicate a general decline in S02 concentrations in Burlington, but suggest an
increase in S02 concentrations in Rutland.
Vermont maintains five monitoring sites that measure particulate matter
(PM 10). The highest 24-hour concentration was recorded at the Rutland site,
which recorded at maximum 24-hour PM 10 concentration of 68 ug/m3. This site
also recorded the highest annual average (weighted) concentration of all Vermont
sites, 23 uglm3. This concentration is well below the annual average NAAQS for
PM1O which is 50 ug/m3. The lowest recorded measurements for PM1O were
recorded at the Proctor Maple Research facility monitoring site. Maximum 24-
hour concentrations were at or below 37 ug/m3, and the annual weighted
arithmetic mean was 11 ug/m3. Over the past five years all five PM1O monitoring
sites have recorded particulate matter concentrations below the annual and the 24-
hour NAAQS. Yearly variability in the data is common, in part determined by
meteorology, transport of particulate matter from distant sources, and changes
70
-------
in the emission strength of local sources. Lower annual concentrations are evident
for the Barre, Brattleboro, and Burlington sites. Although the Brattleboro site
appears to show consistent increases in the maximum 24-hour concentration of
PM1O over the past five years, the concentrations (32-51 ug/rn3) are well below
the NAAQS of 150 ug/m3.
During 1994 Vermont operated five special study CO monitoring sites in
Essex along with one CO site each, in Rutland and Burlington. No exeedance of
the NAAQS for CO was recorded at any site. The highest 1st and 2nd maximum
8-hour concentrations of CO were recorded at one of the special study sites at
Lincoln Street in Essex (5.2 ppm CO and 5.0 ppm CO, respectively).
Vermont is not required to measure the concentration of lead in ambient air.
No measurement data are available.

TABLE 5
Region I 1994 Performance Audit Program
Region I conducts an audit program to assess the performance of Ambient Air Monitoring
Networks to provide operators of these Networks with technical assistance to maintain and
improve overall data quality. The audit procedures used in Region I are adapted from Volume
II, of the U.S. EPA Quality Assurance Handbook for Air Pollution Measurements. Gaseous
pollutant audits are conducted by introducing a known concentration of a specific pollutant
(traceable to the National Institute of Standards and Technology, NIST) into the monitor's
sample intake, recording the response of the audited instrument, and comparing the instrument's
response to the actual or known concentration. Mass Flow and Volumetric Flow controlled
instruments for Paniculate Matter less than 10 microns in size (PM^ are audited by attaching
a reference flow device to the monitor which restricts air flow to a known rate. The known air
flow rate is then compared with the rate of flow indicated by the sampler. These on site
performance audits are conducted by EPA Region I Ambient Air and Emissions Monitoring
Section in Lexington. The total number of Audits have been significantly decreased due to
diminished travel funds and an agumented workload focusing on the PAMS program.
A total of 73 audits were conducted in the six New England States on instruments that
measure Ozone (O3), Sulfur Dioxide (S02), Particulate Matter less than 10 microns in size
(PM10) and Carbon Monoxide (CO).
Of the 36 O3 audits conducted in 1994, 89% passed, 11% were Marginal, and none
failed. Region Fs O3 audits continue to focus on coastal O3 sites due to the concern that O3
may be transported up the coast and peak O3 levels are usually experienced at these sites.
Both of the SO2 audits which were conducted in 1994 passed.
Twenty-eight PM,0 audits were conducted with no failures in 1994. Of the 7 CO audits
conducted in 1994, all passed.

The Pollutant Standard Index
The Pollutant Standard Index (PSI) is a uniform system of measuring air pollution
levels and relating these measurements to the general health effects associated with
different pollution levels. The Index figures enable the public to determine
whether air pollution levels in a particular location are good, moderate, unhealthful
or worse. The PSI converts the measured pollution concentration in a
community’s air to a number on a scale between 0 and 500. PSI numbers are
established for ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, and
particulate matter. The most important number on this scale is 100, since that
number corresponds to the National Ambient Air Quality Standard established
under the Clean Air Act. A PSI level in excess of 100 means that a pollutant is
in the unhealthful range on a given day; a PSI level below 100 means that a
pollutant reading is in the acceptable range.
The intervals and the terms describing the PSI are as follows:
From 0 to 50 Good
From 50 to 100 Moderate
From 100 to 200 Unhealthful
From 200 to 300 Very Unhealthful
From 300 to 500 Hazardous
Table 6 shows the average number of days for each PSI category in nine key New
England counties having critical metropolitan areas from 1984 to 1993. The
counties used for this Table were New Haven and Hartford in Connecticut;
Cumberland in Maine; Middlesex, Norfolk, and Suffolk in Massachusetts,
Hilisborough in New Hampshire; Providence in Rhode Island; and Chittenden in
Vermont. This Table makes several important points. First, there were no days
classified as “Very Unhealthful” during the ten year period. Second, the number
of days classified as “Unhealthful” and “Moderate” are decreasing (a downward
trend). Third, there is an increase in the number of days in these metropolitan
areas that measure “Good” air quality. These overall improvements in air quality
are, in large measure, due to the effective air pollution control programs employed
during the last ten years. Year to year fluctuations in the data, however, are
influenced by year to year changes in meterology, which are not reflected in the
data presented in the table.

Photochemical Assessment Monitoring Stations (PAMS)
The enhanced ozone precursor monitoring initiative, known as the PAMS program, is
one of the most ambitious air quality monitoring programs ever attempted by the EPA and the
States. The overall purpose of this long-term (10 + years) is to monitor the changes in the
atmospheric concentration of ozone precursors and measure the effectiveness of current and
future state and regional ozone precursor control programs. In addition, the data produced by
the PAMS program should greatly enhance future ozone modeling capabilities, help fine-tune
emissions inventories, and provide measurements of key toxic organic compounds that have been
identified as Hazardous Air Pollutants (flAPs).
The PAMS monitoring network is required by the Clean Air Act Amendments of 1990
in ozone non-attainment areas that are classified as extreme, severe, or serious. In general,
there are four different PAMS sites (Type 1 through Type 4) in each network, each of which
serves a different purpose within the network. The Type 1 site measures ozone and its
precursors upwind of the major metropolitan area located in the ozone non-attainment area. The
Type 2 sites measure ozone and its precursors immediately downwind of the metropolitan area,
and are optimally located to characterize the complex emissions that emanate from the
metropolitan area. These sites operate on the more intensive schedule than other PAMS sites,
and are capable of measuring a larger array of ozone precursors than other PAMS sites. The
Type 3 sites are located downwind of the metropolitan area, in the region of maximum ozone
production. Further downwind are the Type 4 sites, located far downwind of one or more
metropolitan areas. In the Northeast, non-attainment areas lay adjacent to each other, along the
eastern seaboard. The abutting nature of these non-attainment areas and the common ozone and
ozone precursor transport across non-attainment areas, provide an opportunity to optimize the
overall New England PAMS network and link it with upwind PAMS sites. It is anticipated that
the New England PAMS network will eventually contain as many as eighteen (18) PAMS sites.
Figure 1 presents the approximate location of existing and recently deployed PAMS sites in New
England.
Most PAMS sites, with some exceptions, measure 56 hydrocarbons (PAMS Table 1) on
an hourly basis, twenty-four hours a day for the summer (June through August). Hydrocarbon
measurements are generally made using automated gas chromatography. At the Type 2 sites,
carbonyl (aldehydes and ketones) are measured along with the hydrocarbon compounds.
Composited samples of carbonyl are measured every three hours during the summer. All sites
also measure ozone, oxides of nitrogen, and surface meteorological conditions on an hourly
basis. As the PAMS program matures, additional measurements of upper air meteorological
conditions will be made at key locations within the overall New England PAMS network.
1993 was the first year PAMS ozone precursor data were collected in New England
during an entire summer. Unfortunately, quality control, and quality assurance (QA/QC)
procedures for several instruments were under development in 1993, and few sophisticated
computerized methods of data transfer and data troubleshooting were available. In addition,
several of the field GCs proved temperamental, producing data of questionable accuracy.
Because of these circumstances, most 1993 PAMS hydrocarbon and carbonyl data have not been
entered into any national data base.
88
-------
The 1994 PAMS data have undergone much better QAIQC procedures, although data
management issues remain a problem. In 1994 six PAMS sites operated thruughout the summer,
and several others underwent field deployment.
A full assessment of the 1994 PAMS data has not been conducted. Such an assessment
is beyond the nature of this report. The following data presentation, however, provides a
cursory analysis of the New England PAMS data base. A more extensive analysis of the PAMS
data will be the topic of future reports.
Figure 2 presents data for total hydrocarbon (THC) concentrations measured at four
representative PAMS sites in New England. The total hydrocarbon data include the 56+ target
compounds and unidentified HCs that were measured by the automated GCs located at the
PAMS sites. Carbonyl concentrations are not included. As expected, the PAMS sites which
were located close to major cities and sources of hydrocarbon emissions recorded the highest
concentrations of THC. The Cape Elizabeth. Maine PAMS site, which is the furthest downwind
site in the ozone transport region, consistently recorded lower daily average concentrations of
THC. The periodic peaks and valleys associated with the daily average THC data, as depicted
in the Lynn. Massachusetts data, reflect cyclical weather changes which favor periodic pollutant
build up (air stagnation and pollution transport), followed by a cleansing of the atmosphere as
weather fronts move from west to east.
Figures 3. 4, and 5 depict the changes in the average concentrations of two hydrocarbon
ozone precursors. isoprene and benzene at the Lynn-MA Type 2 PAMS site during July 1994.
Isoprene is biogenic organic compound emitted by plants, including certain common New
England species, such as oaks. It plays an important role in ozone formation and is emitted by
plants only during the day light and under warm conditions. The other compound, benzene, is
a toxic organic compound (HAP), which is a component of gasoline and is emitted from the
tailpipe of motor vehicles and from fuel delivery systems. Its concentration in the atmosphere
reflects motor vehicle activity and/or build-up under stagnant air conditions. Data presented in
Figure 3 suggests that maximum concentrations of isoprene, as expected, occur during mid-
summer, while Figure 4 suggests that during a typical summer’s day in July, peak concentrations
of isoprene occur during the early afternoon. This pattern is different from that of benzene
(Figure 4 and 5), which does not show any obvious mid-summer maximum, nor a tendency for
mid-day peak concentrations. The concentration of benzene, which is not as chemically reactive
in the atmosphere as isoprene. appears to remain relatively constant (compared with isoprene),
with elevated concentrations during the morning and late afternoon commute. After the morning
commute, there is a gradual reduction during the early afternoon. Benzene concentrations
increase in mid-afternoon, and continue to gradually rise during the evening and night.

Acid Rain Program
Atmospheric Deposition
Atmospheric deposition is composed of both wet and dry deposition. It includes acidic
deposition, deposition of toxic compounds and toxic trace elements, and the deposition of non-
toxic compounds including nutrients. Atmospheric deposition occurs year round, although
seasonal patterns related to weather patterns alter the amount and type of deposition.
Of all the components of atmospheric deposition, acid rain is probably the most
commonly known in New England. In this section most of the discussion will focus on acid
rain, or acid precipitation, which includes acid rain and snow, acid fog and ice. In addition to
the discussion on acid rain, there will be brief reports on dry deposition in New England and
deposition of toxic trace elements and toxic compound deposition.
Acid Precipitation
There are ten (10) acid precipitation monitoring stations in New England. These sites
have measured acid rain and acid snow on a weekly basis (Tuesday to Tuesday) since the early
1980's. The longest continuous acid precipitation monitoring record in the United States is from
a site located in New Hampshire, the Hubbard Brook site, which was established in 1978. This
site and the other nine New England sites are a part of a national network of 200+ sites that
compose the National Atmospheric Deposition Program/National Trends Network
(NADP/NTN). The NADP was established in 1978 to provide a national network of sites to
monitor trends in the chemistry of wet and dry deposition throughout the United States. The
NADP merged with the National Trends Network in the early 1980's to form the NADP/NTN.
The current national network is operated and maintained by a consortium of federal and state
agencies, private industry, and universities.
The New England map presented in Figure 1 depicts the approximate location of the 10
NADP/NTN sites in the region. The sites are equipped with a Belford 5-780 Universal Rain
Gage, and a Aerochem Metrics Wet/Dry Precipitation Collector. Most of sites are located well
inland, with the exception of the Waltham/Boston, Cape Cod National Seashore, and Acadia
National Park monitoring sites, which are locate near the coast. Seasonal and annual differences
in weather patterns influence precipitation and chemical deposition patterns at the inland and
coastal sites. Differences in the annual and seasonal amount of precipitation measured at the
seven New England sites, over the past fifteen years are presented in Figures 2a and 2b.
The data presented in Figures 2a and 2b indicate that the amount of precipitation and
seasonal pattern of precipitation changes over time and by site. These patterns influence the
concentration and deposition of pollutants in precipitation. Inland sites generally record the most
precipitation during the summer (and fall), and the least precipitation during the winter. Coastal
sites (Cape Cod National Seashore, Acadia National Park, and Waltham/Boston), on the other
hand, generally record more precipitation during the spring. This is clearly evident during the
late 1980's and early 1990's.
94
-------
Over the past 15 years, the precipitation data collected at the New England NADP sites
suggest two multi-year intervals with enhanced precipitation. Two-year (paired) averaged data
are presented in Figure 3. These data show enhanced precipitation in New England during the
early 1980’s and again during the early 1990’s. Less precipitation fell during the period 1985-
1988.
Precipitation Chemistry
Almost all forms of precipitation are efficient scavengers of pollution in the atmosphere.
Hence, the chemistry of precipitation reflects changes in the level of air pollutants in the
atmosphere and can be used to provide evidence of trends in air pollution. The NADP/NTN
sites in New England provide a unique view of changes in concentration of pollutants in
precipitation that falls on New England. Precipitation has complex chemistry. Both beneficial
and harmful pollutants are present. Acid precipitation illustrates this. In general, the dilute
chemical constituents of acid precipitation are coniposed of beneficial plant and soil nutrients and
harmful acids, principally sulfuric and nitric acids. Nitrates play several roles; they contribute
to the acidity of the precipitation and can contribute to freshwater acidification, and they can be
a plant nutrient. As a plant nutrient they are important to New England forests, but enhance the
eutrophication of some New England coastal marine environments.
The following anions and cations (and symbols) are measured from precipitation samples
sent to the NADP/NTN central laboratory:
anions cations
Sulfate (S04) Hydrogen (H)
Nitrate (N03) Calcium (Ca)
Orthophosphate (P04) Magnesium (Mg)
Chloride (Cl) Potassium (K)
Sodium (Na)
Ammonium (NH4)
In addition to the anions and cations, the conductance of each sample (a secondary measure of
ionic strength) is also measured. Precipitation samples from all of the NADP/NTN collectors
are shipped every Tuesday to the Central Analytical Laboratory (CAL) at the Illinois State Water
Survey for analysis.
Spatial and Temporal Chemistry of Precipitation
Both concentration and deposition of beneficial and harmful constituents of precipitation
are environmentally important. In this section the yearly deposition patterns (kg/ha) of key
chemical components of precipitation are presented for the 1979-1993 period. These include
sulfate, nitrate, chloride, and potassium ions.
Figure 4 presents the average composite yearly deposition of sulfates, nitrates, and
chlorides for the ten NADP/NTN sites in New England. Nitrate deposition, in New England,
shows no significant long-term increase or decrease in deposition over the period of record. The
95
-------
decrease in the 1987-1988 may be attributed to lower precipitation. Sulfate deposition, on the
other hand, significantly drops during the early 1980’s and again during the 1990’s. The
decreased deposition during the 1987-1988 period is attributed to reduced precipitation.
The final series of figures provide sub-regional views of changes in precipitation
chemistry over the past 15 years. Coastal and inland sites show different patterns of deposition,
over the years. Chloride and potassium enrichment is evident at the coastal sites, indicative of
precipitation that has been influenced by sea spray, especially during 1983 and 1984 (Figure 5a
and 5b). Inland sites, on the other hand do not show similar patterns of chloride or potassium
enrichment. Sulfate, which is also a major constituent of seawater, is also enriched at coastal
sites, as note at the Acadia NP site in Maine (Figure 6a). The Acadia site also records generally
higher deposition of nitrates than the other Maine sites (Figure 7a). This is somewhat
unexpected, since this site is located far from major point and mobile emission sources of
nitrogen oxides in New England, and ocean spray does not contain significant concentrations of
nitrate.
The final set of figures also indicate a south to north and west to east gradient of sulfate
and nitrate deposition (except in those instances where sea spray enhances deposition). As
expected the highest deposition of sulfate generally occurs west of Maine (Figures 6a-6c). The
highest nitrate deposition occurs at the New Hampshire, Vermont, and Quabbin Reservoir-
Massachusetts monitoring sites (Figures 7b and 7c).
