On May 29, 2014 the LSPA Scholarship Fund held its first annual fund-raising golf tournament. Originally conceived of at the annual Past Presidents meeting last summer as a means to raise a targeted amount of $3,500 for the LSPA Scholarship Fund, the tournament actually netted over three times that amount - $11,000 - for the Fund, which celebrates its 10^th anniversary this year.  Over 100 golfers enjoyed a beautiful day, a well-maintained course (Highfields in Grafton), and a hearty post-golf repast.  Prizes were awarded for best-ball team scores and individual skill accomplishments, and a raffle stocked with both golf-related and non-golf related items allowed all the chance to win while supporting the LSPA Scholarship Fund. Photographs of the event, taken by LSPA member and professional photographer Tom Barrasso, are available here.

LSPA Awards WES Professional Practice Grant to Haley & Aldrich Team

The LSPA is pleased to announce that a WES Professional Practice Grant has been awarded to the Haley & Aldrich team of Richard Rago, Kristina McCarthy, and Jane Parkin Kullman for their  proposal entitled “Background Indoor Air Levels of Volatile Organic Compounds (VOCs) and Air-Phase Petroleum Hydrocarbons (APH) in Office Buildings, Commercial Buildings, and Schools."  This is the first WES Grant awarded since its inception.

Tetrachloroethylene, or PCE, is recognized as a toxic chemical and is considered likely to be carcinogenic in humans by all routes of exposure. The degree of its toxicity has been debated for years, especially for the inhalation route of exposure. Two years ago, the EPA finalized PCE toxicity factors, including an inhalation Unit Risk (UR) factor, which is used to assess carcinogenic risk via inhalation. The LSPA encouraged MassDEP to adopt the EPA toxicity values, including the UR. Instead, during its recent reevaluation of PCE toxicity, MassDEP’s Office of Research and Standards (ORS) relied upon a UR for PCE that it had previously derived.  In January 2014, MassDEP released an updated PCE UR which is lower (i.e., less conservative) than MassDEP’s previously derived value, but remains greater than ten times higher (i.e., more conservative) than the EPA value.
