         Asbestos in the Water Supplies of the Ten Regional Cities
Summary               As part of a program to determine the impact of point
              and non-point sources on waterborne levels of asbestos, samples
              of raw and finished water from the ten cities housing regional
              headquarters of the Environmental Protection Agency have been
              examined.  These cities are Boston, New York,  Philadelphia,
              Atlanta, Chicago, Dallas,  Kansas City, Denver, San Francisco
              and Seattle.

                       The results of this examination show that while New
              York, Chicago,  Dallas, Kansas City and Denver  are essentially
              free of asbestos, San Francisco and Seattle may  have detectable
              levels of asbestos in their water supplies and Boston, Philadelphia
                               ViitW
              and Atlanta have significant asbestos levels.

Introduction            The Office of Toxic Substances of the Environmental
              Protection Agency has sponsored a nationwide survey to determine
              the impact of point and non-point sources on waterborne levels of
              asbestos.  This survey covers both natural sites, in which asbestos
              bearing rocks are prevalent, and man-made sources. Additionally,
              it provides for sampling water supplies in a number of cities and
              towns.  This report records the results of the analysis of water
              from the ten major regional cities, headquarters of the EPA
              regional offices.

              Sampling and Analysis Methods
                       Aliquots of the water were vacuum filtered through
              47 mm dia Millipore 0.45 n m pore size filters. This filter was
              then prepared for examination on.the transmission electron micro-
              scope by the direct transfer method.  Nylon support grids were
              used to minimize background signals during X-ray analysis in
              EMMA-4, the combined electron microscope microanalyzer.
              Wherever practicable  samples for analysis were filtered directly
              on site. Exceptions to this were the cities of Chicago, Denver and
              Seattle.

              Results
                       The data for the ten cities are summarized in Table 1.
                       Appendices  1-10,  numbered to correspond to the EPA
              region number, each contain the relevant trip reports describing
              the  sampling locations and conditions, the individual sample sum-
              maries and data print outs and a brief discussion of the results.

Conclusion
                    asbestos levels have been found in the water
supplies of Boston, up to 7.5 million fibers per liter (f.p.l.);
Philadelphia, up to 240 million f.p. 1.; and Atlanta, up to 12 million
f.p.l.  The potential exists for asbestos contamination in the water
of San Francisco and Seattle.  No evidence was found of  asbestos
in the water supplies or sources of New York, Chicago,  Dallas and
Kansas City. A few fibers observed in one of the Denver water
sources might be attributable to background or contamination and
are not regarded as significant.

Appendix 1.  City of Boston

           The city of Boston water supply was sampled on-two occasions-
July 25, 1975 and October 17, 1975.  On each visit one sample of raw
                                                                  ,
water and one sample of finished water was collected at the Western
reservoir, one of the  reservoirs along the distribution system from the
main reservoir situated in central Massachusetts.
           The results of the analyses for asbestiform minerals are
tabulated; sample descriptions and computer printouts are attached.
           The results for the 7.25.75 samples are anomalous.  The
detection of amphibole in the finished water only is not at present under-.
stood.  The amphibole type present could be amosite or crocidolite. (Na is
not readily detectable by the EDXRA (energy dispersive x-ray analysis)
system and some crocidolite  standards have failed to give a detectable peak.)
The possibility of amphibole contamination, such as from a gasket or
insulation cannot be entirely ruled out. The possibility of amphibole from
AC pipe is doubtful in the absence of chrysotile, the predominant asbestos
mineral in AC pipe compositions.  Duplicate analyses from a second filter
set taken on July 25, 1975, will be run in an effort to clear up this anomoly.
These  repeat analyses will be the subject of a supplementary report.

      Generally organics predominate; varying organic residues are
present as well as a general filmy type which is quite common.
Diatoms and fragments noted as well as generally small to moderately
sized inorganic particles. Inorganic particles  include chrysotile,
generally in fibril bundles.

      Generally moderately loaded, although some areas are heavy;
this is due principally to organic residues of varying types and sizes.
Diatomaceous remains, organic fibers, and agglomerated areas are
noted with some of the organic fibers being quite large.   The inorganic
particles are generally small to moderate in size with a wide range of
morphologies.   Chrysotile was detected.

Appendix 2.   City of New York

           The city of New York water supply was sampled on two occasions.
August 11 and October 22,  1975. Raw water was sampled at the Hillview,
Jerome Park and Central Park Reservoirs and finished water at the Hill-
view and  Central Park Reservoirs.  The sample locations are identified
by the digit of the sample number as follows:
                     1.  Central Park
                     2.  Hillview Reservoir - Catskill
                     3.  Jerome Park Reservoir
                     4.  Hillview Reservoir - Delaware

           No evidence of asbestiform minerals was detected in any of the
samples analyzed.  Sample descriptions  and computer print outs are
attached.

 Location:  New York City

 Date visited:  11 August 1975

 McCrone personnel: R. Putscher
                    M.  Palenik

 Site description:  Water is obtained through two systems, (1) The higher level
 at Hillview in Yonkers comes from the Catskill-Delaware system and supplies
 enough natural pressure for any level. The lower level system is the Croton
 water  system.  All 3 reservoirs hold about 1 days supply or about 1 billion
 gallons each.

 They treat water with some CuSO^ for algae control and add chlorine to a level
 to maintain 0. 8-1.0 ppm of free chlorine.  They bring the pH up to 6.9 or
 7.0 with  NaOH and also fluoridate with hydrated fluosilicic acid.

 Dust was sampled at Central Park with an air sample of 90 liters of air for 1/2 hr;
 also collected settled dust inside of station.

 Total samples collected:  3 raw water
                        2 finished water
                        1 air sample
                        1 settled  dust sample

Appendix 3.   City of Philadelphia

           The City of Philadelphia water supply was sampled on two
occasions - May 14,  1975 and October 27,  1975. On each visit samples
of raw and finished water were obtained at the reservoirs at Queen's Lane,
Belmont and Torresdale. Queen's Lane and Belmont reservoirs are
supplied from the Schuylkill River; Torresdale reservoir is supplied from
the Delaware River.
           The results of the analyses for asbestiform minerals are
tabulated: sample descriptions and computer print outs are attached.  The
low levels at Queen's Lane are interesting and point to an asbestos source
intermediate between Queen's Lane and Belmont. The Wissahickon Creek
enters the Schuylkill River just above Queen's Lane,  but it is reported
that mingling of the two streams occurs below the Queen's Lane intake.
A sampling program to determine whether the Wissahickon Creek is the
asbestos source and  also to examine integrated samples taken at the
Philadelphia plants is currently being discussed with EPA region 3
(Joe Friedel).

      Large networklike organic fibers are present.  Small platy
to large blocky inorganics are present as are varying types of
organic residues and fibers.  Inorganic fibers noted including
chrysotile.  Agglomeration of sample material does take place.
Chrysotile occurs in localized areas and not all fibers occurring
in the areas are chrysotile fibers.

     Small to large blocky to chiplike inorganics with the platy types
being in the smaller size ranges.  Diatomaceous remains  and various
types of organic residues are extant.   Chrysotile is present in localized
"masses" and the overlaps make counting quite difficult.   Large organic
fibers are present as well as agglomerated areas.

     Large organic fibers of a network type are present as well as
diatomaceous remains.  Generally small platy and small to quite
large blocky inorganics arc present.  Some agglomeration is noted.
Some inorganic fibers evident,  however, these yield hexagonal
diffraction patterns.  No asbestiform material detected.

         Moderate to heavy loading due mainly to general presence
of an organic residue.  Varying types of residues are present.  Inorganics
range from small to moderate sizes and consist of particles ranging from
platy to irregularly shaped blocky types.  Diatomaceous remains present
and fairly common. Agglomeration of material does take place.  No
asbestiform material  detected.

Appendix 4.  City of Atlanta

           The city of Atlanta water supply was sampled on two occasions,
April 3, 1975 and November 28,  1975.  On each visit a sample of the raw
water and a sample of the finished water was obtained from the Atlanta water
works quality control center located in Northwest Atlanta.  On the 3 April
visit an additional sample was taken from a faucet in the Holiday Inn,  1-20 E.
           The results of the analyses for asbestiform material are
presently available for the samples taken in April only.  The results of the
November samples will be the subject of a supplementary report shortly to
be issued.  The data for the samples taken on April 3 are presented in
tabular form.  The relevant sample descriptions and computer print outs
are attached.
           The Water Quality Control Center is located in Northwest
Atlanta; the motel at which the tap water was sampled is located to the East
of the city. It is possible that the water supply to the faucet sampled does
not come from the main Atlanta system although the motel claimed that it
was Atlanta water.

Appendix 5.   City of Chicago

           The city of Chicago water supply was sampled by City of Chicago
personnel on March 27,  1975 and samples of the raw and finished water
were brought the same day to the Chicago laboratories of Walter C. McCrone
Associates,  Inc., where they were immediately filtered.
           Chicago draws its water from Lake Michigan via a series of
offshore cribs located approximately 1 mile out in the lake.  The samples
brought to McCrone Associates were identified as "Raw  Crib " (Ul), and
"Outlets" (Dl), the latter being finished water sampled at the outlet to the
city distribution system.
           No evidence of asbestiform minerals was detected in either the
raw or the finished water. The sample descriptions and computer outputs
are attached.

Site description: Metropolitan Kansas City has three water treatment plants serving
Kansas City,  Kansas, Johnson County, Kansas, and Kansas City, Missouri.

The Johnson County plant supplies water to purchasers in the communities
neighboring Kansas City, Kansas on the south.  Water from the Kansas River seeps
into 21 wells located along the shore.  It is pumped from these wells into the
water treatment plant for processing.  Samples were obtained from the Kansas
River at the wells and also from the treated water tap at the plant.

Both Kansas City, Kansas and Kansas City, Missouri draw water from the
Missouri River near treatment plants just a few miles from each other.  Raw
and finished water were obtained from these plants.

Recommend   analysis of all samples.

Appendix 8.   City of Denver

           The city of Denver water supply was sampled on two occasions,
26 February 1975 and 15 September 1975.  Samples were taken at both the
Marston and  the Moffat plants and are identified as follows.
  On 26 February  Marston   Ul = Raw water (Conduit 20 in lab)
                            Dl = Finished water (Conduit 30 in lab)
                  Moffat    U2 = Raw water at intake overflow valve
                            D2 = Finished water at hose to turbidimeter
  On 15 September Marston   Ul = Raw water
                            Dl = Finished blend
                  Moffat    U2 = Raw water
                        1100 D2 = Finished No. 3
                        1110 D2 = Finished No. 2
           The results of the analyses for asbestiform material indicate
that there is probably no  asbestos contamination problem at Denver.  It
should be noted that one analyst identified possible amphibole fibers both in
the raw and in the finished  water of Marston on February 26, but at levels
which could be background contamination during sampling or sample pre-
paration; 2 fibers were found in  the raw sample and 1 in the finished sam-
ple.  Again at Marston, on the second visit, chrysotile was observed but
again at possible contamination levels - 3 fibers in 40 grid squares.  We
believe, therefore, that the Denver water  supply system is free of
asbestos.

(N.W. Denver) and at Marston (S.W. Denver). The incoming water to each
plant was sampled in addition to the finished water.  Grab samples were taken
in each case.

Raw water was obtained from the laboratory raw-water tap at Moffat, and
finished water from conduits 2 and 3.

Raw water from the Marston plant was taken at the  pumphouse,  and finished
water from the plant laboratory treated water tap.

Recommend  analysis of all samples.

        Large, thick organic residues appear to be part of a network.
Whole diatoms and fragments thereof were detected.  Very small (<0.05 /mi)
spherically appearing material in the form of agglomerates. Large, chunky
inorganics in the larger size ranges (1 to 10/mi) are present. Also detected
platy and more chunky or blocky inorganics in the range below 2 /an.  Inorganic
fibers are present and appear to be of two basic types — thick with a small
aspect ratio or thin with a large aspect ratio — neither of which is an asbestos
type, but appear to be types of clays. Elementally they contain Fe, Ca, Si,
Mg and Al.  The fibers appear only occassionally.

        Larger organic residues and small (< 0.05 fan) spheroids are
present, as in C8  0226 1145 ULWG2.  In fact, the spheroids are more
prevalent.  A heavier overall organic filming is present.  Inorganics are
less prevalent than in C8 0226 1145 Ul WG2, and are generally smaller
with most material in the < 1.5 /am size range. Small, dense (< 0.2 /mi)
spherical or nearly spherical inorganics are present. Platy inorganics
are at a minimum, as is any evidence of diatomaceous residues.  The
small,  dense inorganics appear to consist of mainly iron, with some silicon
present,  "while the very small {< 0. 05 jum) material in agglomerates is
probably organic.

Appendix 9.   City of San Francisco


           The San Francisco Water System is extremely complex, deriving

its main feed from the Yosemite Mountains some 100-150 miles east of the

city.  From the Yosemites the water is fed via tunnels and pipes (The Hetch-

Hetchy aqueduct) to a number of holding reservoirs which are also fed by

local run off.  The map accompanying the trip report of 5 March shows, in

part, the complexity of the system. A "short narrative" (some 22 pages and

16 pages of Appendices) describing the San Francisco water supply system

is available from the San Francisco Water Department.

           The water system was sampled on two occasions, 5 March 1975

and September 10 and  12, 1975 when the following samples were taken.

   March 5       Ul Alameda East Portal ("Terminus" of the Hetch-
                      Hetchy aqueduct).  This water has been
                      chlorinated and is regarded as "finished" water.
                      No treatment other than chlorination is applied.

   September 10  Ul  Alameda East Portal ("Terminus" of the Hetch-
                      Hetchy aqueduct). This water has been chlorinated
                      and is regarded as "finished" water.  No treat-
                      ment other than chlorination is applied.

           During analysis of the first batch of samples  it became apparent
that sample preparation problems were being experienced. The data reported
for these samples, therefore, is generally that obtained by Murchio and is
identifiable by the letter 'M1  on  the end of the sample code.  The sample
descriptions, however, were not prepared by Murchio and thus although
qualitatively  reflecting the sample do not accurately reflect sample loadings.
           Sampling during the second visit was carried out  by a different.
sampling team and also under a different guide, thus there are some differ-
ences in location at the reservoirs  sampled.  The most noticeable  difference
in results between the two samplings is in the Lower Crystal Springs Reser-
                          C
voir samples where 620 x 10  chrysotile fibers were found on the first visit
and none on the second visit.  We believe this may be explained by the
                                     waiter a me crone associates, inc.

different locations at which the samples were taken.  It was noted in the
trip report for the first visit that the bedrock adjacent to the sampling loca-
tion is extremely friable and that samples of this rock were taken.  These
samples did indeed turn out to have a large serpentine content (determined
by light microscopy) and the rock could be powdered between the fingers.
It is therefore not surprising that the chrysotile content of the first sample
is high.  It might also not be unexpected that a sampling point some miles
distant from the first should show a completely different picture. This
highlights the problem  of trying to characterize a system as complex as
that of San Francisco which could well merit a major study of its own. An
additional explanation of differences between the March and September samples
may be found in the San Francisco Water Department booklet which , in
talking of the Crystal Springs, San Andreas, Pilarcitos section says ....
"Historically this has been a problem water due to high turbidity during the
winter months ..." thus seasonal variation may also be a factor.
           We believe the San Francisco situation may best be summarized
as follows:
            1)  Water from the Hetch-Hetchy aqueduct entering the San
            Francisco water system (at Alameda East Portal) is free
            of asbestos.
            2)  The potential for contamination of the San Francisco
            water system by asbestos - both serpentine and amphibole -
            exists due to natural sources in certain of the holding reservoirs,
            principally Crystal Springs and Calaveras and to a lesser extent
            San Antonio and San Andreas.
            3)  These natural sources may be isolated rock outcrops whose
            total impact on a large reservoir (e. g.  Crystal Springs holds
                      c
            22,580 x 10  gallons) may not be significant.
            4)  No evidence has been found of asbestos in any of the finished
            waters examined.

 Site description:  The San Francisco Water Supply system is extremely complex,
 deriving water from several sources, as far distant as the Hetch-Hetchy
 reservoir in the Yosemites.   There are several local holding reservoirs which
 derive their supplies partly from local sources and partly from the Hetch-Hetchy
 aqueduct.  Part of the system is shown in the attached map.

 S. F. W. D.  provided an engineer and transport to visit the major sources: this
 assistance  is gratefully acknowledged.

 The following samples were taken:

      Ul Alameda East Portal ("Terminus" of the Hetch-Hetchy aqueduct).
         This water has been chlorinated and is regarded as "finished" water.
          No treatment other than chlorination is applied.

      U2  Calaveras Reservoir - Surface water  sampled approximately 50 yards
           from boathouse

      U3  San Antonio reservoir-Surface water sampled at  boathouse

      U4  Lower Crystal Springs Reservoir - Surface water sampled at shore line -
          rock samples also collected - bedrock extremely friable.

      U5  San Andreas Reservoir - faucet on side of chlorination plant -  "raw" water.

      D5  San Andreas filtration plant, outlet no. 1 "finished" water.

      U6  Pilarcitos Reservoir-Surface water.

Weather conditions during sampling were overcast with occasional rain showers.

 Recommend analysis of all samples.

        Irregular, filmy residues present throughout the sample. Diatomaceous
remains are also present in small fragments.  Blocky, irregular inorganics
(usually >0.5/im in size) were detected.  Very small, regular crystals (<0.05/nm)
are well dispersed, never agglomerated.  These appear to be potassium silicates.

as are platy inorganics in the multimicrometer size ranges.  Also
present are smaller chunky inorganics and an occassional spheroidal
particle.  Small fairly regular well-dispersed inorganic particles which
contain K, Si, Fe and Al.  Only an infrequent inorganic fiber was noted.
No asbestiform material was detected.

        Very light loading.  Irregularly shaped organic residues are
prevalent throughout the sample.  The small potassium silicates are
present in this sample also,  as are the blocky type of inorganics in the
small size ranges  — but none in any large sizes.  Most of the material is
under 2 fjan in size.  No asbestiform material was detected.

        Light loading. Large organic fibers present with widths of up
to 5/Lim.  Their physical appearance is very similar to paper fibers,  but
these appear to be part of a network of some sort. Some light, overall
filming is present in areas of the sample.  Small blocky and platy silicates
are present in sizes < 0.5/nm.  No really large inorganics were detected.

        Light material loading, but significant overall organic filming
is present.  Much small (<0.5 /im) blocky to platy inorganics present.
Only very little material in the larger sizes (usually an irregular chunky
inorganic).  Very few fibers detected; none of them asbestiform material.

apparently spherical particulates show up infrequently.  Both platy and
blocky inorganics in the submicrometer range. Occassional organic tubules
with a width generally less than 0.08 /mi, whose sources are objects that
look like sporangium of fungi. Some small diatom fragments are evident.

Appendix 10.   City of Seattle

           Only 1 sample from the city of Seattle has been examined.  This
sample came from the Tolt Reservoir and is therefore raw water.  The only
further treatment to which this water  is subjected prior to passing into the
distribution system is chlorination. The sample  should therefore be
representative also of the finished product.
           The "pedigree" of the sample is as  follows:
           EPA Region 10 Drinking Water Programs Branch is actively
conducting a survey program in their region which includes the Seattle
water supply.   Jack Murchio,  a consultant on this project is also associated
with the Seattle project and permission was received from EPA  region 10 for
the transfer of this sample from their project.  The sample is part of a
limited "round robin" series and had been analyzed by two other laboratories
as well as by Murchio.
           The data presented herein is that of both McCrone Associates
and of Murchio, the latter identified by the final letter 'Mf. The samples
designated DM are duplicates run at McCrone Associates on the actual filter
analyzed by Murchio.  It will be noted that Murchio reports both amphibole
                                              /•            c
and chrysotile fibers present at levels of 1.9 x 10 and 1.5 x 10 , respec-
tively, whereas McCrone finds both below the limit of detection.  Attention
is drawn, however, to the McCrone descriptions which mention poorly
diffracting fibers resembling chrysotile but with elemental compositions
rich in Al, Si,  Ca, Fe and some Mg.  A positive identification of these fibers
has not been made and the possibility that they are a fine amphibole in the
Tremolite-Actinolite  series cannot be ruled out.  We  have examined
Murchio's data and consider that his identification of the chrysotile  is valid.
We therefore believe that both chrysotile and amphibole asbestos are pre-
sent in Tolt reservoir water.

                   CX 0908 1105    DM
     Much organic material present from fibrous forms to the
blobs causing some agglomeration to occur.  Diatomaceous remains
present as well as what could be the sporangia of some fungi.  Small
to moderatety sized inorganics are present of various shapes.  Some
few small,  thin fibers, similar in morphology to chrysotile, are present,
but they do not defract well,  if at all,  and the EDXRA yields Fe, Ca,  Al, Si.
      Figure 1  Probe of fiber similar to chrysotile.  The
                S and Cl come from the organics in the
                sample.
