| Laboratory analytical indicated a historical release occurred at the Lower Latham 3-2G decommissioned wellhead. Four soil samples exceeded COGCC standards for benzene at 0.0500 mg/kg, ethylbenzene at 0.830 mg/kg, naphthalene at 0.468 mg/kg, TPH at 1,499 mg/kg, 1,2,4-trimethylbenzene at 13.1 mg/kg, 1,3,5-trimethylbenzene at 0.487 mg/kg, 1-methylnaphthalene at 1.05 mg/kg, and 2-methylnaphthalene at 1.9 mg/kg. Additionally one groundwater sample exceeded COGCC standards for 14.7 ug/L, and 1,2,4-triemthylbenzene at 1,270 ug/L. This locations lies within a Bald Eagle Roost Site high priority habitat. |
