LASALLE – The U.S Environmental Protection Agency made changes to soil clean up in LaSalle from the Matthiessen and Hegeler Zinc Company. A public meeting was held Monday at LaSalle-Peru High School Auditorium by project manager Damaree Collier to discuss changes to residential soil cleanup contaminated with arsenic, cadmium, chromium, lead, manganese and zinc. The revised plan establishes two sets of cleanup levels for the offsite residential vicinity, being produce garden areas and non produce garden areas. High priority homes will begin sampling or begin cleanup during the first phase. Those include residents closest to the site, those with young children and those with health conditions. Homes within the said group who’s soil is yet to be examined could take up to a year until they see testing done. Concerns were made regarding places where children frequent like parks and schools. According to Collier, portions of Northwest Elementary will be cleaned up including all parks in LaSalle this year. The first phase of cleanup is said to begin this summer.
