| Abstract | Long Description |
This progress report is one in a series describing results of long-term groundwater sampling at Lakewood Plaza Cleaners in south Tacoma. Results of volatile organics of samples collected from two municipal wells and eight monitoring wells in January and August 2000 are included. 1. Monitoring wells MW-20B and MW-16A, as well as municipal wells H1 and H2, continue to have tetrachloroethene (PERC) concentrations exceeding the Model Toxic Control Act (MTCA) cleanup standard of 5.0 ug/L. PERC concentrations in these wells during the past year of sampling were 184 ug/L and 648 ug/L (MW-20B), 22 ug/L and 40 ug/L (MW-16A), and 8.7 ug/L and 10 ug/L (H1 and H2). 2. Trichloroethene (TCE) was detected in MW-20B in January at a concentration of 6 ug/L, which exceeds the MTCA cleanup standard for TCE of 5.0 ug/L. TCE was not detected in MW-20B in August, possibly due to a high quantitation limit (200 ug/L). 3. Cis-1,2-dichloroethene (cis-1,2-DCE) was detected in wells MW-20B (13 ug/L) and MW-16A (0.7 ug/L and 1.9 ug/L). Overall, concentrations are similar to those reported in previous sampling rounds. |
