Mr. Avani Compos
P.O. Box 423
Somerville, MA 02143
Dear Mr. Compos:
On February 23, 2005 the Department of Environmental Protection (DEP) collected air samples
from the basement and first floor of your property located at 9 Tufts Street, Somerville, to test
for the presence of Volatile Organic Compounds (VOCs). DEP initiated this sampling in
response to receiving the results of an environmental investigation of a disposal site located at 50
Tufts Street, which indicated that contaminated groundwater had been discovered near your
home.
The results of the analyses show a low level of contamination, specifically 0.27 parts per billion
volume (ppbv) of tetrachloroethylene (PCE), was found in tlie samples collected on the occupied
first floor of your home. An estimated level of 0.19 ppbv was found in the basement, indicating
the possible presence of contaminants, but at a level below the laboratory’s ability to accurately
report the concentration.
The 0.27 ppbv level is well below the Department’s threshold limit of 1.6 ppbv for PCE, which
would constitute an Imminent Hazard, or a significant risk of harm to health over a short period
of time. The value is also below the levels DEP typically finds in homes. However, based on
the testing results from all of the homes on Tufts Street, DEP believes that this PCE is due to the
contaminants in the groundwater near your home.
Because these levels are so low, DEP recommends occasional venting (opening windows) in
order to further reduce concentrations. Additional measures are not necessary at this time.
