There are more problems at the site of the future Stoklosa Middle School. Representatives from the Coalition for a Better Acre appeared before the city council tonight and expressed their concerns - supported by a consultant's report and a dozen letters sent to city officials over the past year - about contaminated soil that remains at the site. Apparently, the state's Department of Environmental Protection agrees. The city now faces an additional expense of $250000 to remove this soil. Several weeks ago we wrote that the contract for the site preparation work had a completion date of April 2003 and that the contractor failed to comply with that provision, but nothing was done to penalize the contractor for defaulting until earlier this year. Since so much of the future school-usage planning in Lowell is dependent on the opening of the Stoklosa School, any additional delays will be very harmful to the entire school system.
