ABSTRACT
In 1978, the Environmental Protection Agency, through its
Eastern Environmental Radiation Facility, began sampling radon in
drinking water. During the next two to three years, approximately
27 states were included in this pilot study. The subject of this
report is the nationwide study that developed from that pilot study.
The nationwide study, which began in November of 1980, was
designed to systematically sample water supplies in all 48
contiguous states. The results of the study will be used, in
cooperation with EPA's Office of Drinking Water, to estimate
population exposures nationwide and to support possible future
standards for radon, uranium, and other natural radioactivity in
public water supplies.
Samples from more than 2500 public water supplies representing
35 states were collected. Although we sampled only about five
percent of the total number of groundwater supplies in the 48
contiguous states of the U.S., those samples represent nearly 45
percent of the water consumed by U.S. groundwater users in the 48
contiguous states.
Sample results are summarized by arithmetic mean, geometric
mean, and population weighted arithmetic mean for each state and the
entire U.S. Results include radon, gross alpha, gross beta, Ra-226,
Ra-228, total Ra, U-234, U-238, total U, and U-234/U-238 ratios.
Individual public water supply results are found in the appendices.
As with any survey that only samples a limited number within
the overall population available for sampling, certain biases will
occur in the final results. By only sampling public groundwater
supplies serving at least 1000 or more people, many smaller public
groundwater supplies with elevated radon levels were not sampled
(He84). Small public groundwater supplies and private wells tend to
have the highest radon in water levels (He84). The Ra-226 and
uranium results are biased since only samples with elevated gross
alpha were analyzed for Ra-226 and uranium. The Ra-228 results are
even more biased since Ra-228 analyses were only performed for
samples with elevated Ra-226.

1.0 INTRODUCTION
During 1978, the Environmental Protection Agency (EPA), through
its Eastern Environmental Radiation Facility (EERF), began sampling
radon in drinking water. During the next two to three years,
approximately 27 states were included in this pilot study, the
purpose of which was to determine the need for a nationwide study of
radon in drinking water; to demonstrate the feasibility of such a
study; and to develop a limited data base of radon in drinking water
nationwide. Water supplies sampled during the pilot study were, in
many cases selected because of known or suspected elevated levels of
radon or out of convenience leading to arbitrary or random results.
For the most part, state health personnel were free to sample any
type of water, including private wells and wells not used for
drinking water. The results for drinking water have been summarized
in another publication (He84). These include private wells, public
surface water, public water supplies (may include both groundwater
and surface water) and public groundwater - all by state and U.S.
averages (geometric means). The pilot study results will not be
discussed in any great detail in this report due to the statistical
uncertainty associated with much of the data. The subject of this
report is the nationwide study that developed from that pilot study.
The nationwide study, which began in November of 1980, was
designed to systematically sample water supplies in all 48
contiguous states. The results of the study will be used, in
cooperation with EPA's Office of Drinking Water (ODW), to estimate
population exposures nationwide and to support possible future
standards for radon, uranium, and other natural radioactivity in
public water supples.
-------
2.0 STUDY DESIGN
The study design called for sampling only finished water;
limited sampling to once per water supply; targeted composited
samples or system samples instead of individual well supplies;
encouraged sampling as near the source of water as possible; and
excluded surface water supplies (no significant radon was detected
in surface water in the pilot study) and supplies that served less
than 1000 people. Our intent was to collect samples that
represented what people actually consume from a given public water
supply.
During the pilot study, many samples were untreated water which
may not have represented what people were actually consuming
(Pr83). Treatment processes such as the use of aerators may
significantly reduce radon levels to the public. Storage tanks also
allow radon levels to decline due to radioactive decay of radon.
For practical reasons, each water supply was sampled only
once. Typically, radon levels are not expected to vary much more
than a factor of two seasonally if the source of water remains the
same. This was observed in a study in the area of Houston, Texas
(Pr81). Water systems having more than one well can have
significant differences in radon levels from one well to the next.
For this reason, consumer tap or composite samples were specified in
order to obtain average levels or more representative levels
applicable to the entire water system. Samples collected near the
source of water were preferred in order to obtain a fresher sample
with less decay of radon.
During the pilot study, samples from public surface water
contained little or no radon. This lack of radon was confirmed by
another approximate 25 public surface water supply samples taken
during the nationwide study.
Originally, the nationwide study specified looking at all
public groundwater supplies serving 5000 or more people. After
receiving a detailed listing of all public groundwater systems
serving 1000 or more people (EPA80), it was obvious that an
adjustment was needed in the size of the water system to be
sampled. At the 5000 person level some states had only a few water
supplies to be included. In order to balance the need for a
representative sampling of each state and the artificial requirement
that less than 200 water supplies be sampled in any one state
-------
(contract limitation), a collection scheme was formulated (see Table
2.1). For half the states, water systems serving 1000 or more
people were scheduled for sampling. These states included those
with small populations or if possible with known or suspected
elevated radon levels. An attempt was made to put the remaining
states at the 3000 person level. Six states remained at the 5000
person level: four of which exceeded the contract limitation at the
3000 person level and the other two were limited by the total
contract dollar amount for all 48 states.
Each state was given the opportunity to participate in the
collection of samples via a service contract. A copy of the
procurement statement associated with each service contract is shown
in Appendix A as Exhibit A.I. Each sample taken was identified by
the information found on the sampling and analysis form (see
Appendix A, Exhibit A.2). A copy of our sample collection criteria
is presented in Appendix A as Exhibit A.3.
Radon sampling and analysis methods will not be discussed in
this report. Previous papers cover this area in detail (Ho83,
Pr77). Specific topics discussed include sampling method, liquid
scintillation counting, Ra-226 calibration, radon concentration
determination, and precision and accuracy of radon determinations
(Ho83).
In addition to the radon samples, a one gallon cubitainer water
sample was collected for each water supply included in the study.
These samples allowed us to obtain other data on natural
radioactivity in public drinking water for very little extra
collection effort. Our analyses of these samples were guided,
generally, by the requirements of the Safe Drinking Water Act (SDWA)
(EPA76).
All samples were analyzed for gross alpha and gross beta. If
the gross alpha was equal to or greater than 5 pCi/1, a Ra-226
analysis was performed. Shortly after the study began, the cutoff
for Ra-226 analyses was dropped to 3 pCi/1 to provide more data.
Ra-228 analyses were performed for samples where the Ra-226 was
equal to or greater than 3 pCi/1. During the second half of the
study, samples whose gross beta exceeded 15 pCi/1 were also analyzed

for Ra-228. Where the gross beta exceeded 50 pCi/1, an attempt was
made to Identify contributing radionuclldes by gamma spectroscopy
and strontium analysis.
Originally, uranium and thorium analyses were performed if the
gross alpha was equal to or greater than 15 pCi/1* After a few
months into the study, the cutoff for uranium and thorium analyses
was reduced to 3 pCi/1, the same as for Ra-226. The cutoff for any
radionuclide-specific analysis was a function of the EERF's sample
load at any given time. The vast majority of the samples were
analyzed under the lowest cutoff criterion. After performing more
than 100 thorium analyses, it was decided that thorium analyses were
unnecessary because the concentrations found in groundwater were
very low (i.e., typically less than 0.1 pCi/1 for Th-227, Th-228,
Th-230, and Th-232). At these levels, the measurements are not
significantly different from zero. One Ra-226, uranium, and thorium
analysis was performed for each state involved in the study,
regardless of whether any sample from a given state met our cutoff
criteria. This provides us with at least one measurement for each
state.

3.0 RADON AND OTHER NATURAL RADIOACTIVITY MEASUREMENTS
Locations of 2457 public groundwater supplies samples for radon
are shown in Figure 3.1. Figure 3.2 shows locations of 2510 public
groundwater supplies sampled for gross alpha and gross beta. The
primary differences in the two location maps are the absence of
radon results for Maine and the fewer radon results than gross alpha
and gross beta results for Kansas and Mississippi. Nationwide, the
public groundwater systems represent about 44 percent of the total
groundwater usage (Table 3.1) or about five percent of the total
number of public groundwater systems. Thirteen states were not
included in the study primarily because~oT~a shortage of manpower
and money in the respective states. Even though the state health
departments were reimbursed for the collection of samples, the
reimbursement did not cover actual expenses incurred in the
collection effort.
Radioactivity results are summarized in several different ways
to provide readers of this report with practical options in
understanding the overall impact of this study. All summaries are
based on raw results found in Appendix B.
The use of maps is helpful, in showing both location and the
magnitude of levels but the mapping process requires a certain
amount of localized averaging of the data (the highs and the lows
are averaged out in a uniform grid system). When data are missing
(e.g., those states that did not participate in this study),
extrapolation and interpolation are necessary in producing the
maps. The use of extrapolation and interpolation has its
limitations since results are produced that potentially are more
dependent on computer software than actual measurements. The sole
purpose of the maps is to show general trends nationwide. If that
idea is kept in mind when using the maps, then the maps can serve a
useful purpose. It is suggested that the three dimensional maps be
used in conjunction with their corresponding two dimensional
(contour) maps so that the position of peak levels can be located
more accurately.
Frequently, concentrations of a radionuclide in environmental
media are close to zero. When the actual concentration of a nuclide
is zero, the net counting results should statistically show a
distribution of negative and positive numbers about zero. This
occurs when the background count is subtracted from a sample which
has only background activity. When reviewing the data in this

report, caution should be exercised in the interpretation of
individual negative values. Obviously, a negative activity value
does not have physical significance. Such numbers, however, are
significant when taken together with other observations which
indicate that the true value of a distribution is near zero. When
an average of several measurements produces a result less than zero,
this indicates a negative bias in the measurement procedure.
3.1 U.S. Rn-222 Results
Table 3.2 presents arithmetic means, geometric means, and
population weighted arithmetic means for water supplies sampled for
Rn-222*. Figures 3.3 and 3.4 display Rn-222 concentrations by
topographic mapping and contour mapping, respectively. A frequency
distribution of Rn-222 concentrations is shown in Figure 3.5 with
the corresponding population distribution associated with these
Rn-222 concentrations given in Figure 3.6.
Some of the water supplies sampled during the nationwide study
did not meet our sampling criteria. These include surface water
supplies and groundwater supplies not serving at least 1000 people.
Surface water supply results were separated from the groundwater
supply results. All public groundwater results were included in the
analysis of groundwater results.
* The arithmetic mean is commonly used to describe a normal
distribution of data while the geometric mean (or median) typically
is employed for characterizing log normal distributions of data. In
calculating a geometric mean, all data points are given equal
weighting. For an arithmetic mean calculation* the large values
dominate the resulting mean. Environmental radioactivity
measurements tend to follow a log normal distribution; therefore, a
geometric mean is more representative of the data. On the other
hand the arithmetic mean is needed for dose and health effects
(risk) calculations. A third mean was computed based on
population. The arithmetic mean was weighted by population. The
purpose of the resulting population weighted arithmetic mean is to
eliminate any bias due to variations in water supply sizing. The
population weighted arithmetic mean can also be used for dose and
risk computations.
All mean and standard deviation results are computer
generated. All results should be rounded off to three significant
figures or less when using these results.

Of the more than 2500 public water supplies sampled in the
nationwide study, 26 of these supplies were public surface
supplies. Surface supply results for Rn-222, gross alpha, and gross
beta are summarized in Appendix C.
The vast majority of the sampled groundwater supplies served at
least 1000 or more people. Only 95 groundwater supplies served less
than 1000 people. Of these, five served less than 100 people.
Rn-222 results by population range are given in Appendix 0.

3.11 U.S. U-234/U-238 Ratio Results
U-234/U-238 ratios are shown fn Table 3.12 by state and U.S.
arithmetic means, geometric means, and population weighted
arithmetic means for supplies having a total U exceeding 3.5 pCi/1.
Figures 3.28 and 3.29 display U-234/U-238 ratios by topographic
mapping and contour mapping, respectively. A frequency distribution
of U-234/U-238 ratios is shown in Figure 3.30. For comparison
purposes only, U-234/U-238 ratios based on all results are given in
Table 3.13 and Figure 3.31.

4.0 DISCUSSION OF RESULTS
4.1 Section 3 Discussion
4.1.1 Rn-222
Elevated Rn-222 concentrations, determined in this study, are
found primarily in Virginia, North and South Carolina, the New
England states, and scattered locations in the Midwest and western
parts of the country. These results generally coincide with what
was observed during the pilot study except the concentrations are
not as elevated. This decrease in activity is thought to be due to
the intended purpose of not sampling water supplies because they are
known or thought to be elevated (an attempt at minimizing biased
results). In most cases, the elevated levels tend to be highly
localized. Exceptions to this observation are found in Maine and
Rhode Island (and possibly other New England states) where elevated
levels tend to be more widespread instead of isolated cases.
Relying on mean values for characterizing a state, the entire U.S.,
or even a county within a state can be misleading due to the wide
variations observed on the state level and even the county level.
For example, North Carolina has a number of water supplies that have
elevated levels but the geometric mean (or median value) is very low
due to the high number of supplies that are low in Rn-222 (see Table
3.2).
Radioactivity results are summarized in several different ways
to provide readers of this report with practical options in
understanding the overall impact of this study. All summaries are
based on raw results found in Appendix B.
A limited number of public surface water supplies were sampled
in this study. As can be seen from the results in Appendix C,
Rn-222 concentrations were very low. This same result was seen in
the pilot study. Gross alpha and gross beta results were also very
low.
During the pilot study a general trend was observed where on
the average smaller public groundwater systems exhibited higher
Rn-222 concentrations. Combining the results from the nationwide
study and the pilot study, this trend remained (He84). This trend
may be due in part to less treatment such as aeration, less water
holdup resulting in Rn-222 decay, and low capacity wells giving less
Rn-222 dilution. As can be seen from Table D.I in Appendix D, this
trend was not evident in the nationwide study alone due in part to
the very few samples collected at the < 100 people served water
57
-------
systems. Comparing the U.S. means based on all groundwater samples
collected during the nationwide study (Table 3.2) with the U.S.
means based on groundwater systems serving 1000 or more people
(Table D.I), essentially no difference was seen.
The absence of Rn-222 data from Maine during the nationwide
study was unfortunate since many public groundwater supplies in
Maine exhibit elevated levels as was seen in the pilot study. On a
nationwide basis the omission of Maine data does not significantly
alter nationwide trends in Rn-222 concentrations. On a regional and
state basis, areas within Maine with higher than average
concentrations or lower than average concentrations are averaged out
by extrapolation and interpolation from other New England states.
4.1.2 Gross Alpha
Elevated gross alpha levels were seen primarily in the Rocky
Mountain states (Figures 3.7 and 3.8). Gross alpha measurements
were used as a screening device for Ra-226 and uranium. Generally,
the elevated levels nationwide are due to elevated uranium. About
85 percent of the supplies had gross alpha concentrations of less
than 3 pCi/1 (Figure 3.9). The geometric mean for the U.S. was 0.5
pC1/l (Table 3.3).
4.1.3 Gross Beta
Elevated gross beta concentrations were very spotty as seen in
Figures 3.10 and 3.11. Theoretically, elevated Ra-228 levels should
be associated with elevated gross beta levels. In practice, gross
beta levels only serve as a qualitative indicator of Ra-228 at
best. The geometric mean for the U.S. was 2.0 pCi/1 (Table 3.4).
4.1.4 Ra-226
Elevated Ra-226 concentrations (Figure 3.14) were seen from
North Carolina to Florida along the Atlantic Ocean and the Midwest
(Illinois, Wisconsin, Minnesota, South Dakota, and Kansas). Very
low Ra-226 levels were found in the western states. The geometric
mean for the U.S. was 0.6 pCi/1 (Table 3.5). About 9 percent of
water supplies analyzed for Ra-226 exceeded 5 pC1/l (Figure 3.15),
the national interim primary drinking water regulation for radium
(FR76, EPA76). No nationwide correlation was observed between
Rn-222 and Ra-226 concentrations, while in some local areas a
correlation may exist. The reader 1s cautioned that these results
only apply to public groundwater supplies where the gross alpha
result was 3 pC1/l or greater (see Section 2.0).
58
-------
The absence of Ra-226 data from Iowa during the nationwide
study was unfortunate since many public groundwater supplies in Iowa
exhibit elevated levels. Fortunately, these elevated levels have
been documented in other reports.
4.1.5 Ra-228
Elevated Ra-228 concentrations were generally found in water
supplies where the Ra-226 was elevated. Illinois, Minnesota, North
Carolina, South Dakota, and Wisconsin tended to be the most elevated
in Ra-228. The geometric mean for the U.S. was a biased 2.1 pCi/1
(Table 3.6). Only water supplies where the Ra-226 concentration was
equal to or greater than 3.0 pCi/1 were analyzed for Ra-228. A few
water supplies were analyzed for Ra-228 when the gross beta was
equal to or greater than 15.0 pCi/1. About 24 percent of the water
supplies analyzed for Ra-228 (Figure 3.16) exceeded 5 pCi/11, the
national interim primary drinking water regulation for radium (FR76,
EPA76), based on Ra-228 alone.
4.1.6 Total Ra and Ra-226/Ra-228 Ratio
Elevated total Ra concentrations were found in nearly every
state where total Ra analyses were performed (Table 3.7). The state
geometric mean exceeded 5.0 pCi/1, the national interim primary
drinking water regulation for radium (FR76, EPA76), for every state
where total Ra analyses were performed except Georgia, Virginia, and
Wyoming (Table 3.7). About 79 percent (77 out of 97) of the water
supplies analyzed for total Ra exceeded 5 pCi/1 (Figure 3.17). The
reader is cautioned that these results only apply to public
groundwater supplies where the Ra-226 result was 3 pCi/1 or greater
(see Section 2.0).
In about 28 percent of the water supplies, the Ra-228 exceeded
the Ra-226 (Figure 3.18). By only analyzing a sample for Ra-228
when the Ra-226 is equal to or greater than 3.0 pCi/1 potentially
allows a water supply with elevated Ra-228 but Ra-226 less than 3.0
pCi/1 to avoid the radium regulation (FR76, EPA76). The
Ra-226/Ra-228 ratio geometric mean for the U.S. was 1.5 (Table
3.8). According to Michel and Moore (Mi80), Ra-226/Ra-228 ratios as
low as 0.3 have been shown to exist in South Carolina. Similar
situations were also noted in Georgia (C183). Ratios as low as 0.3
were also observed in this study (Figure 3.18).
59
-------
4.1.7 U-234, U-238. Total U, and U-234/U-238 Ratio
Elevated uranium concentrations were observed in many of the
western states (Montana, Idaho, Wyoming, Colorado, New Mexico, and
Utah), the Midwest (North and South Dakota, Minnesota, Wisconsin,
Kansas, and Oklahoma), and a few eastern states (Maine,
Pennsylvania, and North Carolina) as seen in Figures 3.19, 3.20,
3.22, 3.23, 3.25, and 3.26. The U.S. geometric means for U-234,
U-238, and total U were 1.1 pCi/1 (Table 3.9), 0.4 pCi/1 (Table
3.10), and 1.5 pCi/1 (Table 3.11). About 14 percent (50 out of 362)
of the water supplies analyzed for uranium exceeded 10 pCi/1 (Figure
3.27), the EPA's Office of Drinking Water (ODW) Health Advisory (HA)
for uranium (La83). The reader is cautioned that these results only
apply to public groundwater supplies where the gross alpha result
was 3 pCi/1 or greater (see Section 2.0).
The ratio of U-234 to U-238 is of interest to those areas where
elevated uranium concentrations exist. Using uranium results whose
total U exceeded 3.5 pCi/1, Figures 3.28, 3.29, and 3.30 and Table
3.12 were constructed. Low activity samples with their inherent
uncertainty were excluded. About 73 percent (99 out of 136) of the
water supplies had a U-234/U-238 ratio between 1.0 and 2.0. The
geometric mean for the U.S. was 1.7 (Table 3.12). About 9 percent
(12 out of 136) of the water supplies had ratios that exceeded 3
(Figure 3.30) whose locations are shown in Figure 3.29. If all
results were included, the geometric mean for the U.S. was
calculated to be 2.7 (Table 3.13) with about 36 percent (107 out of
296) of the water supplies exceeding 3 (Figure 3.31).
4.2 Regional Approach
One limitation in producing U.S. maps of concentration is that
peaks and valleys of concentration tend to be averaged out
excessively, especially in those regions where elevated trends are
not widespread and numerous water supplies were sampled. For
example, several highly elevated water systems in Rn-222 were found
in North Carolina, South Carolina, and Virginia, but the results
were obscured in Figures 3.3 and 3.4. On the other hand, in areas
where few water supplies were sampled and elevated levels of Rn-222
occurred (examples are found in the Far West), elevated levels for
those cases were prominent in Figures 3.3 and 3.4. The obscuring of
results was primarily seen in the case of Rn-222, but also, to a
lesser degree, applied to other U.S. radioactivity maps.
60
-------
By presenting results in groups of states or regions (see
Appendix E), some of the localized averaging was eliminated and more
detail was preserved. EPA has ten regional offices throughout the
U.S. Each regional office serves at least two states. For example,
Region II services New York and New Jersey while Region IX
encompasses California, Arizona, Nevada, and Hawaii. Regional maps
were produced for all ten regions, except Region VI, based on the
nationwide study. Rn-222 and gross alpha were plotted for each of
nine regions (Appendix E) while Ra-226 and total uranium were only
plotted for those regions where sufficient numbers of results were
available. Ra-228 was also plotted for Region VII (Figure E.18).
A special region or group of states was also selected for
further study. This region involved Georgia, North Carolina, South
Carolina, and Virginia. In general, elevated levels of
radioactivity, especially Rn-222, were observed in this four state
region (Figures E.30, E.31, and E.32).
In order to better define the distribution of Rn-222
nationwide, Rn-222 results for those states which did not
participate in the nationwide study, but did participate in the
pilot study, were combined with the nationwide study results. Also
included in the expanded results were some unpublished Rn-222
results (Pr79) for Arkansas, Iowa, Louisiana, Nebraska, and Texas.
Both the pilot study and unpublished results were for public
groundwater supplies only. A map of expanded locations is shown in
Figure 4.1. Except for the states of Washington, Michigan, West
Virginia, Maryland, Connecticut, and Texas (only one location) where
no results were available and the states of California and Kansas
with sparse coverage, the continental U.S. has been widely sampled
for Rn-222 as displayed in Figure 4.1. On the U.S. scale maps, the
addition of results from states which did not participate in the
nationwide study did not significantly alter the results for those
states as seen in Figures 4.2 and 4.3 as compared to Figures 3.3 and
3.4. Having radon results from all 48 contiguous states would be
desirable, but in practice may not be necessary in order to generate
U.S. scale maps. This is not the case with larger scale maps such
as regional and state maps. Rn-222 regional maps were produced for
Regions I, II, VI, VII, and IX (Figures E.33-E.37) based on the
expanded locations. As would be expected the regional maps based on
the expanded locations (Figures E.33, E.34, E.36, E.37) gave more
detail for states that were missing in the nationwide study as
compared to corresponding Figures E.I, E.3, E.15, and E.24 based on
the nationwide study only.

4.3 Selective Monitoring
4.3.1 Areas With High Rn-222 Activity
As was discussed in Section 4.2, elevated levels tended to be
averaged out or obscured by previous mapping efforts. One mapping
technique that helped to lessen this problem was to plot the
locations of water supplies exceeding a specified concentration.
Using the Rn-222 results from the nationwide study, plots were
generated showing the locations of water supplies exceeding
500 pCi/1 (Figure 4.4), 1000 pCi/1 (Figure 4.5), 2000 pCi/1 (Figure
4.6), 5000 pCi/1 (Figure 4.7), and 10,000 pCi/1 (Figure 4.8). At
the 500 pCi/1 level, the Rn-222 distribution for the U.S. was
widespread. At the 1000 pCi/1 level, the distribution became more
confined to the East Coast with scattered results in the Midwest and
Far West. At the 2000 pCi/1 and 5000 pCi/1 levels, results were
concentrated on the East Coast. At the 10,000 pCi/1 level, only
North Carolina and South Carolina were included (Figure 4.8). The
highest Rn-222 concentration exceeded 16,000 pCi/1.
Using the results depicted in Figure 4.1 and other Rn-222
results for public groundwater supplies (pilot study, AL75, He79,
Ka77, Mc82, Pr79), the same levels as before were plotted in Figures
4.9-4.13. Similar nationwide distribution patterns were observed at
the 500 pCi/1, 1000 pCi/1, and 2000 pCi/1 levels. With the addition
of Maine results (pilot study, He79) and pilot study Rhode Island
and Virginia results, the distribution at the 10,000 pCi/1 level not
only included North Carolina and South Carolina but also Virginia,
Rhode Island, and Maine. At the 5000 pCi/1 level Maine and
California were added (Figure 4.12). The lone California result was
due to a small groundwater supply serving a remote BLM fire station.
Since extreme values for Rn-222 are localized, an effective
monitoring program for Rn-222 could be accomplished by only sampling
public groundwater systems where extreme values of Rn-222 in
groundwater have been observed in the past. Similar selective
monitoring schemes may also apply to Ra-226, Ra-228, and uranium in
those areas where elevated levels have been observed.

4.3.2 Mining Locations as a Screening Method for Uranium
Logically, a correlation should exist between where uranium Is
found In the earth and uranium in groundwater In the same areas.
Looking at areas where uranium is elevated in the earth's crust
should provide some information as to where elevated levels of
uranium in groundwater may exist. By plotting the locations of
mining operations associated with uranium (DoI79), Figures 4.14-4.16
were produced. Both inactive (Figure 4.14) and active (Figure 4.15)
locations along with a combination of both active and inactive
locations (Figure 4.16) were developed in order to correlate with
total uranium concentrations in public groundwater systems (Figures
3.25 and 3.26). The mining operations not only include uranium
mines but also mining ventures in which uranium is a potential
byproduct to the principle product. A good qualitative correlation
is seen for mining areas in Wyoming, Colorado, Utah, and New Mexico
where elevated uranium concentrations in public groundwater systems
are observed. Additional uranium data (Co83, NM80, Dr81) from
public groundwater systems help to strengthen this correlation. As
a way to monitor public water supplies for uranium without sampling
all supplies for uranium, a monitoring scheme based on sampling
those areas with a higher probability of elevated uranium in
groundwater (areas associated with uranium mining operations) could
be implemented as a first cut or screening method for uranium.
Since uranium analyses (especially isotopic) are expensive, any
technique that lessens the need to analyze for uranium but provides
adequate monitoring should be explored for possible use on a
nationwide basis.
4.4 Predictive Modeling
Interest was shown recently in the use of predictive modeling
to estimate concentrations of radioactivity in groundwater (M181,
Mi83, He84). For example, Michel (M183, He84) was in the process of
correlating Ra-228 concentrations in groundwater with rock type (or
aquifer type). Similar correlations may be possible for Ra-226,
uranium, and Rn-222.

The author of this paper has attempted to estimate Rn-222
concentrations based on Rn-222 measurements in adjacent regions and
using computer software which generated a Rn-222 concentration
surface above the area of interest (Kn84). By specifying a latitude
and longitude within the continental U.S., a Rn-222 concentration
was estimated. The accuracy of the estimate was dependent on a
number of factors including map surface scale (U.S., regional, or
state scale), closeness of measurements to the point of interest,
and the algorithm used to generate the surface matrix. The accuracy
of the estimate increased going from the U.S. scale (more localized
averaging was required) to the regional scale and then to the state
scale (less localized averaging was required). While computer
artifacts were generated where measurements were lacking, this
approach shows promise in making a first cut prediction. As the
Rn-222 data base increases in coverage, the accuracy of the model
should increase. Similar predictions can be made for other
radioactivity in water supplies. These estimates are potentially
less reliable since the data bases are much smaller and have much
less coverage than for Rn-222. While no specific examples of this
approach are given in this paper, it is anticipated that such
examples and further applications of this technique will be the
subject of a future paper.

5.0 SUMMARY AND CONCLUSIONS
Based on the results of this study and previous studies
involving limited areas of the U.S., no widespread areas with highly
elevated Rn-222 in public groundwater systems were observed. Only
localized areas of the eastern U.S. showed relatively high levels of
Rn-222 (10,000 pCi/1 and above). The reader is cautioned that only
public groundwater supplies serving 1000 or more people were sampled
(see Section 2.0). Pilot study results (He84) indicated smaller
public groundwater supplies on the average tend to have higher radon
levels.
Based on the results of this study, 1.6 percent of the people
served by public groundwater systems in the contiguous 48 States
(approximately 1.15 million people) are served by drinking water
supplies exceeding the EPA maximum contaminant level of 5 pCi/1 for
radium. Some water supplies not sampled in the study are also
reported to exceed the 5 pCi/1 level.
Based on the results of this study, 0.45 percent of the people
served by public groundwater systems in the contiguous 48 States
(approximately 0.31 million people) are served by drinking water
supplies exceeding the 10 pCi/1 level for uranium suggested by an
EPA/ODW Health Advisory (La 83). Some groundwater supplies not
sampled in the study could exceed the 10 pCi/1 level, especially
where the earth's crust is enriched in uranium.
Based on the results of this study, thorium levels were shown
to be extremely small in public groundwater supplies. Water
supplies having thorium concentrations exceeding 0.1 pCi/1 would be
unusual and those exceeding 1.0 pCi/1 would be extremely rare (pilot
study results).
As with any survey that only samples a limited number within
the overall population available for sampling, some biases will
occur in the final analysis of results. In the case of radium and
uranium results, the reported results consisted of those samples
which exceeded a 3 pCi/1 gross alpha screening level. The results
of this survey are applicable to the upper end of the distribution
function for radium and uranium in public groundwater supplies.
Therefore, for the most part, the lower end of the distribution
function has been excluded in this survey of radium and uranium
levels.

6.0 RECOMMENDATIONS
The following recommendations are made regarding future work
involving natural radioactivity in public groundwater supplies:
1. No more widespread sample collection should be undertaken at
this time. In the future, special studies may be appropriate
in localized, high activity areas.
2. Analyze remaining samples for Ra-226, Ra-228, U-234, and U-238
or randomly select a nominal 500 samples for further analysis
since less than 17 percent of the samples collected in this
study were analyzed for Ra-226, less than 5 percent for Ra-228,
and less than 15 percent for U-234 and U-238. By increasing
the size of the database, more representative average values
will be obtained.
3. Analyze all samples for Pb-210 in which the gross alpha and
gross beta exceed 5 pCi/1 (400-500 samples) in order to
establish a Pb-210 database.
4. Consult the U.S. Geological Survey and state geological surveys
for data and information on natural radioactivity in
groundwater.
5. Gather data from other databases of natural radioactivity such
as those maintained by each state to meet the requirements of
the Safe Drinking Water Act for radionuclides (EPA76, FR76).
States are only required to report violations. This additional
data (data from water supplies not in violation) would be very
helpful in predictive modeling efforts.
6. Develop predictive models of natural radioactivity in
groundwater based on geology. Such models might be based on
all available data relating natural radioactivity to rock type
and used for predicting levels in groundwater and the resulting
dose and health effects associated with these levels.

APPENDIX A
ADDITIONAL INFORMATION ON THE STUDY DESIGN
86
-------
Exhibit A.I
PROCUREMENT STATEMENT*
Using the supplies and equipment provided by the EERF,
public water supplies shall be sampled for radon. In addition to the
radon samples, a water sample shall be collected for possible analysis for
other radionuclides. All samples shall be promptly returned to the EERF
using the boxes and mailing tubes supplied by EERF. The enclosed list of
public water supplies specifies which supplies to sample. Only these
supplies shall be sampled and reimbursed under this agreement. All
samples shall be collected within six (6) months following receipt of a
sampling list from the EERF. The Project Officer shall receive a monthly
progress report during the six-month sampling period outlining the status
of sampling and any problems which could delay completion of the sampling
plus steps taken to overcome these problems. At the completion of the
sampling program the sampling kit shall be returned to the EERF unless
otherwise instructed. Also, within one month after the final sample is
collected, the Project Officer shall receive a complete summary of
sampling data to include the name of the supply; date sampled; information
on the well such as depth, aquifer being pumped, etc.; type of water
treatment; population served; and other pertinent data as may be
available. The data and information developed under this contract shall
not be published or made publicly available without the written consent of
the Project Officer.
* Samples were collected by state health department personnel using this
procurement statement as a guide.

SAMPLE COLLECTION CRITERIA
(Finished Water Only)
Single Well Public Water System
Preferred Method:
Alternative:
One set of water samples at consumer tap. (Try to
collect samples as close to the water supply as
possible.)
One set of water samples from well, storage tank, or
other suitable finished water sampling point.
(Specify where taken)
Multiple Well Public Water System
Preferred Method:
Alternative al:
Alternative a2:
One set of water samples at consumer tap. (Try to
collect samples close to the beginning of the
distribution system, e.g., near water treatment plant
and/or storage tanks.)
One set of water samples from individual well serving
largest percent of public water system population
(finished water only).
One set of water samples from any other suitable
finished water sampling point (specify where taken).
Definition:
Note:
One set of water samples means a one (1) gallon
cubitainer of water plus two (2) liquid scintillation
vials for radon in water samples.
The EPA is trying to collect samples that can be used
in nationwide and state averages, i.e., baseline
data. The data may also serve as a screening device
for identifying areas warranting more detailed and
comprehensive studies at a later date (St80).

APPENDIX B
RADIOACTIVITY RESULTS FOR EACH PUBLIC WATER SYSTEM SAMPLED
Note: All concentration and counting error results are
computer generated resulting in numbers that are less accurate
than what is presented (i.e., up to five significant figures
are implied). All results should be rounded off to no more
than three significant figures when using these results.
