Soil Tests From Williams Street Baseball Field Posted
Greenwich Public Schools has announced the results from the soil tests conducted at the Williams Street Baseball Field as part of the New Lebanon School building project.
The findings show that arsenic in 40 of the 84 locations tested ranged from 11.1 to 500 mg/kg throughout the site, with a majority of the exceedences occurring within a large fenced off area. One exceedence of 500 mg/kg was also located within the protective fence.
Here is the entire press release from Greenwich Public Schools:
The delineation analysis for the Supplemental Phase II Environmental Site Investigation of the Williams Street Baseball Field has been issued.
Greenwich Public Schools Administration has conducted a series of environmental investigations as part of the New Lebanon School building project.
Background and Previous Investigation
The initial investigation of the Williams Street Baseball Field site (March 2015 Reports) included the collection of three soil samples. Two of the three samples contained arsenic at levels above the Residential Direct Exposure Criteria established by the Connecticut Department of Energy and Environmental Protection (CTDEEP). As a result of this, the Greenwich Public Schools (GPS) commissioned a Supplemental Limited Phase II to further investigate the William Street Baseball Field (April 2015 Report).
Twenty soil borings were advanced and a total of twenty soil samples were collected in a gridlike pattern across the field. The soil samples were collected at a depth of 0-1’ below ground surface. Five samples, of the 20 collected, contained arsenic at levels above the Residential Direct Exposure Criteria.
As a result of the Supplemental Limited Phase II, the Board of Education Administration commissioned a further investigation to horizontally and vertically delineate the arsenic exceedences at the William Street Baseball Field (June/July 2015).
Between April and May 2015, 51 delineation borings were advanced to delineate the vertical and horizontal extent of arsenic contamination. Based on a review of the results, 33 additional samples were advanced. The 84 borings produced 126 samples for laboratory analysis.
Results and Conclusions
Laboratory results identified concentrations of arsenic in 40 of the 84 locations ranging from 11.1 to 500 mg/kg throughout the site. A majority of the exceedences occurred within the large fenced off area. A few exceedences occurred a meter east of the of the larger fence’s perimeter. The fence will be expanded to encompass those exceedences.
During the investigation, one exceedence of 500 mg/kg was located within the protective fence. This exceedence level requires a formal notification to the Connecticut Department of Energy and Environmental Protection. The Administration initially notified the State (verbally) and the public in a June 9, 2015 press release. Formal written notification was submitted to the State on July 30, 2015.
The Administration is currently working with our partners at Greenwich Department of Public Works on a remediation and restoration plan. Until the soil is remediated the protective fence will remain in place.
