Tests cite Billerica, Lowell waste water as perchlorate source

levels of perchlorate coming from the Billerica waste water treatment
plant. 

Tests taken on Sept. 7 showed 158 parts per billion entering the Concord
River from the treatment plant. The Lowell waste water treatment plant
showed a similar patter in the last round of testing at the end of
August when water leaving the plant tested at 18 ppb. 

"We are working with the treatment plants ... to figure out what we need
to do," said DEP deputy commissioner Ed Kunce,. 

The state DEP had been testing in the Concord river after the last round
of tests, taken at the end of August, indicated levels of perchlorate
where the Merrimack and Concord rivers meet. The Billerica waste water
treatment plant showed the first appearance of perchlorate in the
Concord River. Perchlorate was also found down stream at Lawrence Street
and Rt.133 in Lowell at just under 10 ppb. Kunce said the findings,
while helpful in giving the DEP and Tewksbury direction in testing, are
"difficult and complex to resolve."
