The city-owned indoor gun range, James G. Mangan Rifle and Pistol Range in south Sacramento's Mangan Park, on 34th Avenue near Freeport Boulevard, was closed more than 15 months ago because it was polluted by hazardous levels of lead dust after decades of operation. But the city has never cleaned that toxic dust from the interior of the range, nor from the roof, according to interviews and internal city documents. Environmental scientists specializing in lead contamination say the tainted particles that remained should have been cleaned long ago, and may pose an environmental hazard for park users and residents in the surrounding neighborhood.

Adults can suffer memory loss, headaches and mood disorders, and lead poisoning has been linked to miscarriages.
