Article in Land and Water Highlights Lochmueller Group's work at Grand Lake St. Mary's

Projects like this one highlighted in Land and Water can help prevent harmful algae blooms, like the one that affected Toledo’s drinking water supply. The article is about a pilot project in the 2,310-acre watershed that feeds into Grand Lake St. Mary, about 95 percent of which is used for agriculture. Lochgroup was a part of a team that designed a buffer zone with five treatment processes that help clean the stormwater runoff before it entered the lake. Lochgroup designed a seven-acre wetland that absorbs phosphorus and nitrogen by passing the effluent through different zones – including aerobic and anaerobic portions – in the wetland.

Bernardin Lochmueller & Associates Changing its Name as Part of Expansion

EVANSVILLE, Ind. – Bernardin Lochmueller & Associates is changing its name and as of May 19 will be called Lochmueller Group (Lochmueller). The change is in response to confusion that stemmed from Lochmueller’s strong growth in Illinois and Missouri. In company documentation, the former name was often abbreviated, and that abbreviated form overlapped with another regional provider of similar services.

With the new name, Lochmueller’s leaders hope to both retain the link with the company’s deep roots in the Midwest and strong reputation for service, while shortening the name and creating a new, unique logo that will aid in the firm’s expansion.

“We as a company are who we are today because of Keith Lochmueller, and we wanted to continue to honor that heritage,” said Lochmueller’s President Michael Hinton. “At the same time, the new name adds a punch that we feel will give us a leg up as we continue to push into new geographic markets.”

Founded in 1980, Lochmueller provides infrastructure planning, environmental services, and engineering design to clients nationwide. It employs more than 160 staff in offices in Evansville, Indianapolis, and Jeffersonville, Indiana; Chicago and Troy, Illinois; and St. Louis, Missouri.

Green Approach to Combined Sewer Overflows Saves Communities Millions

Today the US EPA estimates that there are over 770 communities in 31 states and the District of Columbia with combined sewer systems serving 40 million people. These systems discharge around 850 billion gallons of untreated wastes into rivers, streams, lakes, and estuaries each year, polluting waterways with bacteria and other pathogens, toxic chemicals, pesticides, and debris.

SRMS: Helping Communities’ Transportation Investments Go Farther

A “perfect storm” in transportation infrastructure for communities and counties is brewing through a combination of volatile fuel and construction materials, decreasing revenues for road maintenance, uncertainty in future highway funding, and increasing complaints about road conditions. One way for communities and counties to address this critical challenge is to adopt a preventive maintenance approach to prolong the life of their pavement assets.

What Bridges are Teaching Us
About Bats

Long misunderstood, today bats are gaining popularity due in part to their role in controlling pests that harm crops and carry diseases. As development spreads, bats are being pushed out of their traditional roosts and are looking for new homes, like bridges.Click here to see how one such bridge in Southwestern Indiana is unveiling new information about the endangered Indiana bat, which may help stabilize its population and eventually move it off the endangered species list.
