Inside 918 W Dooley. This is one of the living room areas. The core was taken near the nw corner of the dining/living room area. Readings were found to range from 80 - 100 microR/hr at 6 Outside 918 W Dooley. 3 sample corings were taken along the east wall of the residence, in the alley. The samples were taken to correlate with the corings taken inside, in front of the sink and dishwasher. The corings were taken below the kitchen window, going north towards the drainage pipe. Samples were called F1, F2, F3. values ranged between 4.8 - 11.8 Kcpm at the top of the corings to 2.9 - 16.5 Kcpm at 12 - 24 Outside 918 W Dooley. 3 sample corings were taken along the east wall of the residence, in the alley.

Looking northeast. This photo shows that the site was secured at the end of today's removal activities. The removal activity of contaminated soil has ceased due to (1) level came down from as high as 400 microR/hr to 28 microR/hr (2) the structural integrity of the residence was compromised. ER started filling the holes with concrete on 8/17/12. The removal activity of contaminated soil has ceased due to (1) level came down from as high as 400 microR/hr to 28 microR/hr (2) the structural integrity of the residence was compromised.
