Short Description

Annual groundwater monitoring at Lakewood Plaza Cleaners was conducted in February and September 2003. Three wells continue to have PCE concentrations that exceed the MTCA cleanup standard of 5.0 ug/L: monitoring wells MW-20B (230 and 239 ug/L) and MW-16A (59 and 26 ug/L), and municipal well H1 (1.3 and 6.4 ug/L). TCE was detected in MW-20B in September at an estimated concentration of 5.4 ug/L, which exceeds the MTCA cleanup standard for TCE of 5.0 ug/L. Cis-1,2-DCE was detected in wells MW-20B (12 ug/L) and MW-16A (2.4 and 0.5 ug/L). The federal MCL for cis-1,2-DCE is 70 ug/L. Overall, concentrations are similar to those reported in previous sampling rounds.

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 one municipal well and seven monitoring wells in February and September 2003 are included.

  • Monitoring wells MW-20B and MW-16A, as well as municipal well H1, continue to have tetrachloroethene (PCE) concentrations exceeding the Model Toxic Control Act (MTCA) cleanup standard of 5.0 ug/L. PCE concentrations in these wells during the past year of sampling were MW-20B (230 and 239 ug/L), MW-16A (59J and 26 ug/L), and H1 (1.3 and 6.4 ug/L).

  • Trichloroethene (TCE) was detected in MW-20B in September at an estimated concentration of 5.4 ug/L, which exceeds the MTCA cleanup standard for TCE of 5.0 ug/L. TCE was not detected in MW-20B in February due to a high quantitation limit (100 ug/L).

  • Cis-1,2-dichloroethene (cis-1,2-DCE) was detected in wells MW-20B (12 ug/L) and MW-16A (2.4 and 0.54J ug/L). The federal maximum contaminant level for cis-1,2-DCE is 70 ug/L.

    Overall, concentrations are similar to those reported in previous sampling rounds.
