I have no idea what they are shooting, but using unjacketed bullets and cleaning without gloves is a more likely cause of lead exposure than breathing it in outdoors.
The range operated that way for about a year until more than a dozen officers started feeling sick and reported testing positive for lead in their blood.

What?!? At an outdoor range?  How many thousands of rounds were these cops shooting per week?  I am skeptical. >

The range has been in use for the better part of a century. I have no issue believing that there are significant amounts of lead contaminating the soil. >

Yeah, I have no problem at all believing that.  Any range is going to be contaminated with lead.  
With a backstop at a minimum of 20 yards away, though, how much lead dust do you think the shooter is going to inhale?  Indoor ranges tend to be a problem with lead due to small size/close backstop and due to recirculated air, but the risk is mainly confined to employees who work there every day, not people who shoot a couple hundred rounds at most a year.  
I've never heard of someone getting lead poisoning at an outdoor range. >

I guess that's a different type of lead poisoning... >

Yeah… There really needs to be a considered upper limit of delivery speed to count as poisoning. >

Wait this was an outdoor range? I read not getting air filtration for the bullet traps being an issue thinking it was a stupid oversight being an indoor range. Are they literally standing in front of these traps?
