The removal and replacement of contaminated soil at Boysen Park's baseball and softball fields started in July 2023 and is expected to be completed in a few weeks.
About 2 feet of surface soil is being removed from the main baseball field, a softball field and a smaller practice diamond. The soil is being replaced with new, clean soil.
Work led by the city and overseen by the state Department of Toxic Substances Controls starts in early July and finishes later in the month or by early August.
The ball fields have been temporarily closed since 2021 and will reopen after cleanup and fields repair in late 2023.
Boysen Park's playgrounds, picnic areas, open grassy field, southwest soccer field, tennis courts and remaining areas on the north and south sides are unimpacted by any contamination and remain open.
Ball fields cleanup is being done after testing found levels of lead, arsenic and other compounds.
While the exact cause of the contamination is not entirely known, a landfill operated at the site of what is today Boysen Park from the early 1900s to mid-1930s. The landfill collected and buried household waste.
After serving a landfill, the site was used as a public rifle range up until the mid-1940s.
The site was transformed into Boysen Park in 1958.
