GREENWICH - Greenwich town and school officials are trying to determine how much soil at the high school's campus is contaminated by potentially harmful chemicals.
All of the school's athletic fields were closed after soil at a nearby construction project recently tested positive for contamination.
School officials say they believe just one field is affected, but they have closed all of them as a precaution while environmental specialists conduct tests to see if the grounds are safe.
First Selectman Peter Tesei was among a group of town and school leaders who met this morning. He says right now state environmental experts are testing soil throughout the property for more contaminants.
Officials also discussed the creation of a contingency plan in case the grounds need to remain closed.
Tesei says the chemicals in the soil are PCBs, synthetic mixtures used in construction for years before they were banned in the 1970s.
