J.S. Held adquiere GLI Advisors para fortalecer sus servicios de apoyo a proyectos de construcción en el oeste de EE. UU. y Hawái
LEER MÁSAn Illinois school district was notified by the state that potentially hazardous PFAS chemicals had been detected in its local water supply well. District leadership wanted to understand if this translated to an exposure scenario for students and staff within their facilities.
Experts from J.S. Held's Environmental, Health & Safety practice designed a robust water-testing program to ensure that all district school facilities were tested to determine PFAS exposure levels in the water supply. This process involved using dedicated PFAS sampling procedures to ensure data integrity and prevent cross-contamination, a common concern when testing for contaminants in the part-per-trillion (PPT) range. The experts also recommended a series of supplemental chemical tests that would help the district evaluate and price potential treatment system options.
Based on the work of J.S. Held’s experts, the district received a comprehensive set of results showing PFAS concentrations in the school’s water inlets and at sensitive points around the facilities, including drinking water fountains and kitchen faucets, which were not necessarily correlated with PFAS concentrations from the water supply well.
Overall, several exceedances of USEPA Maximum Contaminant Levels for PFAS in drinking water were identified, and J.S. Held’s work enabled the school district to take appropriate actions to mitigate risks to its students and faculty.
