The JBS slaughterhouse in Beardstown, Ill., released an average of 1,850 pounds of nitrogen a day into a tributary of the Illinois River in 2017, states a report by the nonprofit Environmental Integrity Project. Despite that figure, which JBS disputed, the facility is still within the allowable discharge limit under the Clean Water Act.
Foxconn's heralded $10 billion manufacturing plant in Mount Pleasant, Wis., is the subject of environmental scrutiny, as a company unit has been fined $1,200 over stormwater rushing off the construction site during heavy rains last month. State authorities determined that a pond to restrain rainwater was not finished before crews began grading.
A concrete flood wall along the Mississippi River in Burlington, Iowa, revealed a few weaknesses, as a 21.2-foot crest caused cracks and seepage. The wall has already undergone several trials this year, during which the pores in the concrete were exposed to river water and sediment.
A South Korean study evaluated urban stormwater pipe network structures in terms of the relationship between peak rainfall and runoff. Researchers concluded, among other things, that looped networks implemented with affordable budgets are superior and, more generally, that network complexity is a crucial factor in reducing the risk of flooding.

Tight underwater spaces are a challenge for rigid exploration robots, but researchers at Florida Atlantic University have a solution: a soft robot that mimics a jellyfish. The pump-powered device also provides a delicate touch in fragile environments such as coral reefs.
Rapid prototyping, small-batch output and product design on a tight budget all come together in Shenzhen, China, making it a prime destination for engineers. MIT, in fact, is teaming with Shenzhen's Southern University of Science and Technology to give mechanical engineering students firsthand experience with rapid scale-up of product design.
Rocket Lab is planning mass production for its boosters with a new 80,700-square-foot facility in Auckland, New Zealand, that it hopes will produce one Electron rocket booster per week. The plant will carry out vertically integrated manufacturing and expects to use 3D printing for the primary components of the rocket's electric turbopump engine.
