DUNDALK, Md. (AP) — The employer of the construction worker killed at a Baltimore wastewater treatment plant this week has been identified as a contractor that’s seen three other worker deaths this year.

Baltimore City Department of Public Works spokesman Jeffrey Raymond tells The Baltimore Sun 36-year-old Transito Rodriguez Cruz worked for Archer Western. Raymond says the Atlanta-based Walsh Group subsidiary was contracted to build a system to remove nitrogen and phosphorous from the effluent at the Back River plant.
