Appendix D
Valzinco Samples from Puddle
TABLE D-1 Metal Concentrations and pH in Water Samples Collected in Stagnant Puddles on Top of Tailings Piles at the Valzinco Mine (Spotsylvania County)
| Sample | Comments (sample name) | pH | Al (mg/L) | As (mg/L) | Cd (mg/L) | Cu (mg/L) | Pb (mg/L) | Sb (mg/L) | Se (mg/L) | Tl (mg/L) | Zn (mg/L) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Valzinco filtered water at mine | Collected from a small puddle on the tailings (VLZN-10-2 FA) | 1.1 | 1038.40 | <0.02 | 3 | 59 | 2.1 | 0.01 | <0.04 | <0.005 | 2,300 |
| Valzinco unfiltered water at mine | Collected from a small puddle on the tailings (VLZN-10-2 RA) | 1.1 | 1090.32 | 0.28 | 3.1 | 62 | 1.5 | 0.01 | 0.07 | <0.005 | 2,400 |
NOTE: Valzinco data samples are described as “an anomalous geochemical setting.”
