M?TRACT
A study of pollution o£ Cold ‘?later Creek and content of
uranium that may be .found in the earth at the Airport .
Storage Area, st. Louis, Uissouri revealed the followinga
1. Creek water samples were well within the limits
of tole ranee.
2. M.ld samples adjacent to the area ranged in value ·
from nil to 190 times that of normal uranium
content in soil.
H~rever, no final conclusion should be drawn from these
samples.
Ad~itional samples both under normal and adverse weather
conditions need to be taken so that the evaluation o!
hazards presented by erosion and drainage both into the
Creek and adjacent area can be more soundly determined.

Egrpose of Raoo~
During the period z~~rch 23 to March 28, 1948 mud and l’later samples were
taken by Paul B. Klavin in the a raas adjacent to t.lJ.e air:9ort storage area,
Robertson, !o:;issouri. This sampling survey nas planned in order to study
(1} the pollution of Cold ~1ater Creek by materials stored or dun?ed at the
ai rport a rea, and (2) the content of uranium that might have soaked into the
soil.
~thod of _s.t u9z
Seventeen water samples werG collected in 500 cc bottles fr~ the various
drainage ditches and streams alongside and adjacent to the storage area. In
addition, samples were collected from the main stream, cold 7’fater Creek.
Samples of water ware obtained from various hiehway bridges frO!ll its oriein
to its mouth.
Fifty mud samples ”are tal(en in 250 cc bottles at both surface and subsurface
levels 01•-.3″ and .3″ to 7″ raspectively; the latter procu.Nd to indicate
pene·tr ation. Using a two inch di.a.metar pi-pe to obtain a 211 x 3″ cylinder
of mud, the sub~urface and surface mud was sampled throughout tht3 area west
of the property, where the most noticeable drainage from. the storage area
occurs. Thera lVere 20 sampling stations along a north-eouth line follotdng the
wast fence appro:x:i.:nately 25 – 30 feet apart. ‘Ihe remaining staticns were wast
of the fenced area along the drainage ditches and a9pr~ll~tely 100 feet apart.
In addition to these samples four control mud samples were taken at distances
of one and five miles from the area.
Soil and liquid samples were· analyzed by the University of Ro<'~he ster for uranium content. A soil analysis result of o.o signifies no uranitun detect ed. If present, the uranium concentration is less than 0.1 micrograms l;.ranium per gram of soil. The sensitivity of the water analysis is 0.0004 micrograms uranium per cc of water. ~scriotion of TeiTain aqjoining...MQ...E!:OJ29rlY at J:!obertson..a J:j. ss~t1 Just prior to the period of mud and water sampling t here had boen gena r-a.l and frequent rains causi ng sluage and residue to be washed onto the adjoining property wast of the area. The area nearest tha west fence was swampy and boggy with many small drainage ditches emanating .from the area itself. In the central portion of the adjoini..l'lg area there is a swampy stretch running northsouth for 250 feet and east"""'f9st f'or 125 feat. 'l'liElnty to thirty feet south of asphalt cover ed Brawn Road which borders the area on the nortn., there was a pool of l'fater 50 feet in length. Due wast of t his pool thora was a.nother swampy stretch 125 feet in length originating or terminating at the swampy section desc1~bed above. All of the ground west of the Sl'Bmp area leading to Cold Vlater C:reek was firm terr ain. Two IDAi."l ditchew originati.ng near the fence area were avident1 one 25 feet directly south of and parallel to Brown Road and the other, a larger one originates in ~~a residue area and runs due west for 500 fest into the creek. -1- . As previously m3ntioned, the rainy weather conditions prior to the' sa:npling period were unusually severe and caused the appearance t)f many ephe;aeral ditches in the area. Cold ilater Creek was swollen and turbulent along its entire course to the Missouri River. Discussion The results of the mud analysis showed conclusively that s01no3 residue from the area had been washed "estward towards the creek. It should b1~ recognized that the weather conditions at the time the samples W9re taken af~ects the amounts of uranium obtained par sample. 1.he uranium tolerance value has been given by K. z. ~~rgan a:s: 60 micrograms uranium per milliliter of water. All values from the seventeen water samples taken are well within the limits of tolerance, ths highest,.lO micrograms uranium per milliliter of water being 17% of the recommended laval. Fieure 1 shows the fall-off of intensity in Jlg/ml w.i th respect to distance. It can be noted here that although the path or the creek south of the area ~1s not been plotted, the concentration throughout was nil. The figure generally accepted for normal uranium in soil is 4 x 10-6 grams per gram. Of the 50 soil samples analyzed, the values range from nil to 190 tin:es this figure. Figures 2 and 3 show the number of samples takEn at surface and sub-ourface levels and their multiples of normal. Figura 4 contains plots of both surface and sub-ourface soil concentrations west of the fenced area, showing once again, the sharp drop in inte.nsity with distance. Conclusion '!he study revealed the followinit~ 1. The creek vrater samples ware well within the limits of tolel"ance. 2. }.fud samples adjacent to the area ranged in value from nil to 190 times that of normal uranium content in soil. It is felt that a sound conclusion cannot be drawn from the s~9les shown hera because of the unusual conditions that prevailed at the tillB of sampling. Because of the excessive rains, two divergent forces would tend to affect the results. There would be a tendency to a higher result because of tho increased erosion; while the increased quantity of water would tend to dilute 1;be concentration. With comprehensive data the evaluation of hazards presanted by erosion and drainage both into the creek and adjacent area can be more soundly determined. It is thersfore recommended that subsequent soil and liquid samples be taken during essentially dr.y conditions. -2- ------------------- . • '0 t z 3 • ~ ' 1 a O'- 2 l " ~ 6 7 a 9 o 34567891 ~±Tr-: f -:: - ·~ ,: _ + --~-ttt~ -. ~ --- 8 -- • ·. ~ . :!' . .... --~~ ... -.. .• • 1. - : • •. • t . ,;;;. ..: ·, J,.~,·.
