The nineteen samples submitted for analyses were collected by URS, locations are given. in Figure 1. Sample character, and descriptions were not provided, and we cannot respond to sample quality nor to the degree to which they may or may not represent the study area. The purpose of this-study was to determine the speciation of lead- bearing phases in each of the samples for an assessment:. of bioavailabilty. The term speciation in this report is meant to refer to the form(s) of lead and their frequency of occurrence in each sample. Bioavailability of the lead will be characterized based on such factors as; lead species (stoichiometry), grain-size, and associations. Associations refer to the mode of occurrence of the lead-bearing phase ie. is it INCLOSED within a .non-lead mineral, is it RIMMING another mineral, is it CEMENTING or ENCRUSTING other mineral(s), or is it free within the soil MATRIX. SAMPLE PREPARATION AND ANALYSIS Approximately 1.O grams of air-dried material from each sample was mounted in epoxy for polishing and microscopic examination. Details of mounting and polishing are given in Appendix I. 2 Samples were analyzed on a JEOL 8600 Superprobe located in the Department of Geological Sciences, University of Colorado, Boulder, Colorado. A combination of EDS (energy dispersive spectrometry), and WDS (wavelength dispersive spectrometry) along with the aid of a backscatter electron detector were used in this study to isolate and identify the lead-bearing phases. Operating conditions include a 15Kv accelerating voltage, 20-30 NanoAmp cup current and a 1 micron beam size. Wavelength spectrometer crystals: LIF-PET for lead, PET for sulfur, LDE1 for oxygen, and LDEC for carbon were used in analyses. To ensure a high degree of accuracy in the microprobe analyses spectrometers were peaked daily and mineral standards were analyzed randomly as unknowns. Calculated accuracies ranged from 1 to 5 percent of the amount determined and MDL's (minimum detection limits) ranged from 0.01 to 0.03 wt~. Point counts were made on each sample until a total of at least 100 lead-bearing particles were identified or 8 hours scanning time was reached. Particles were isolated by traversing each sample from left-to-right and top-to-bottom at a low magnification 40-100X and then at a higher magnification 200-600X. ELECTRON MICROPROBE ANALYSES Nearly 70~ of all the lead-bearing phases found in this set of samples are found to be cerussite or FePb oxide, Figure 2. cerussite tends to be found free within the matrix or encrusting other silicate minerals. It also often rims galena particles. cerussite still accounts for more than half of the total bulk lead ro z 0 h U O r7 W a S a. o o N p~ i i LL w q/ V/s a H w a 3 0 s ova N o a ~~ ~ o yO Qa o m' i~ ,o ¢v g D ~~~ `s N ~~ LLO pN ~ ~~6 ~ ~ o O ~~~~~ pS ^ N a a P,e i - o 8/ e~' a N 8 ~ /J o. m L y g ~~O 4 e ASPEN URS Pb Bar Ga Pb Org Ang Pb Phos MnPb Ox FePb Ox FePb Sulf Cerr 0 5 10 15 20 25 30 35 40 45 50 LEAD PHASE FREQUENCY BURM -RESIDENTIAL SOILS FIGUP.E 2 1 y ~ C within the samples. FePb oxides ,have variable lead contents, ranging from 1 to 28 percent. They are free with the sample matrix or form as cements or coatings on other silicate phases. The remaining 30~ of the lead-bearing population 'is predominahtly composed of FePb sulfate, and MnPb oxide.. The MnPb oxide is .most often found free within the matrix or as cements. FePb sulfate is usually free within .the matrix or found rimming pyrite grains. The data indicates. that approximately 90% of -the lead-bearing phases. counted fallbetween 1 and 20 microns.. The. largest proportion of grain's within this, size range are found free within. the sample matrix. Only one phase, .galena, illustrated an association which would limit its bioavailability; the other lead- bearing phases should be considered .available. Microprobe analyses of other silicate grains does suggest that a VERY thin (1 to 50 angstroms) coating of FePb oxide may be common; however, this would not.. represent a very significant portion of the lead pool. LEAD BIOAVAILABIL.ITY AS IT RELATES TO SPECIATION Lead uptake, through digestion or inhalation, in these samples is likely controlled by the minerals;. cerussite, Fe-Pb oxide, Fe-Pb sulfate, and Mn-Pb oxide. Although .galena is common in some. of the samples, (particularly the coarse fraction), these are generally rimmed by cerussite or in rare cases anglesite and therefore not likely to be a significant contributor to. the lead-pool when the material is digested. cerussite is likely to be the most F significant phase for four reasons: 1) it is the first or second most abundant lead-bearing phase, 2) it contains 77 to 80 percent lead by weight, compared to Fe-Pb oxides, Mn-Pb 'oxides and Fe-Pb sulfates which range from 2 to 50 percent lead by weight, 3) its morphology has a much higher surface area of exposure (increasing solubility), 4) the Fe-Pb oxides and Mn-Pb oxides are generally larger in size and therefore less likely to be digested or inhaled. a PHASE FC-003-250 FW007 250 RW008-250 if Cerussite 12%8::14%3 43%3 :_.

Cont. 12 IIRS and CDM COMBINED SAMPLING In the combined URS and CDM program I was able to study 28 samples from the Smuggler Site, representing the 0 to 2 inch depth interval. In these samples over 18,000 lead grains were identified ahd counted. The normalized (based on total particles counted) frequency for the site as understood at the time of this report is illustrated in Figure 3. FePb oxide and cerussite are overwhelmingly the most common lead-bearing phases with cerussite dominating the lead source pool. Most (90%) of the lead-bearing particles in these sieved samples fall within the 1 to 10 micron grain size. Only minor differences in mineralogy are noted in the burm and soil samples. This is not what I would have anticipated; however, it may be due to the fact that we are ONLY looking at the 0-2" depth interval were mineralogy is controlled predominantly by oxidation. Burm samples show a distinctive increase in FePb sulfate along with an absence of anglesite and Pb phosphate. The site has a crude zonation from NE to SW: NE ++ Galena, Anglesite, cerussite FePb Oxide, cerussite SW ++ Pb Phosphate, MnPb Oxide cerussite s 13 Pb Phosphat Fe-Pb Sulfat z Mn-Pb Oxid w Fe-Pb Oxid m Q°Anglesit w Galen O Cerussite SMUGGLER MINE Aspen, Colorado v ~u 30 40 50 5 15 25 35 45 NORMALIZED FREQUENCY CDM Soils ~ URS Soils Burm e e e e e a FIGLRE 3 14 This zonation reflects the movement away from the mines into an area with increase residential input; ie. soils and fertilizers. Mineralogically galena is the only lead-bearing phase that should be excluded from the total lead pool due to its consistent lack of bioavailability. Clay or silicate coatings are found on some lead- bearing phases; however, I would estimate this to be only about 20- 25 °s of the time and seldom complete. Many times lead-bearing grains are closely surrounded by. other silicates; however, significant void space can be found between these grains and although this may deter fluid movement it will not restrict it. 14C 120 U 100 80 u_ w 60 a p 40 Q w J ASPEN URS SAMPLE RW008-250 Pb Org 5% FePb Sulfate 10%° Cerussite 43% Galena 7% Anglesite 4% FePb Oxide 29% MnPb Oxide 4% 5 ~ 10 20 30 50 75 100 0 20 250 GRAIN-SIZE Microns ASPEN URS U Z w O w w w a 0 w 140 120 100 80 SAMPLE RW-001-250 Pb Phos Tr Cerussite 3% FePb Sulfate Tr MnPb Oxide 20% FePb Oxide 77% 5 10 20 30 50 75 100 150 200 GRAIN-SIZE Microns ASPEN U RS o 60 U w 50 C~ 40 u_ w Q 30- d 0 20- w 10- SAMPLE RW005-250 MnPb Oxide 6% FePb Oxide 32% Cerussite 49% Galena 8% Pb Phos 2% FePb Sulfate 2% ASPEN URS U Z w O w w w o_ 0 Q w 350 SAMPLE RH005-250 Cerussite 30% 150 1 FePb Oxide 30% FePb Sulfate 17% MnPb Oxide 10% Galena 4% Pb Org 10% 5 10 20 30 50 75 100 150 200 250 GRAIN-SIZE Microns ASPEN URS 1 w 1 C~ w u:. w Q a_ Q w J 3-i SAMPLE RH004-250 FePb Oxide 33% Pb Phos 25% Cerussite 39% FePb Sulfate 2% PbCI 1 a iv GU ~U bU /5 100 GRAIN-SIZE Microns ASPEN URS 120 SAMPLE RH003-250 100 Z Pb Org 9% w 80 Cerussite 26% Q w FePb Oxide 37% 60w cn FePb Sulfate 8% n- 40 MnPb Oxide 13% w Galena 3% J 20 Anglesite 3% 5 10 20 30 50 75 100 150 200 250 GRAIN-SIZE Microns 300 U 250 z w 200 w w 150 o=..100 0 w sn ASPEN URS GRAIN-SIZE.
