At a Midwest printed circuits manufacturer, achieving optimal water treatment efficiency became a critical concern. The 80,000 square foot facility faced the constant challenge of promptly detecting disruptions in their treatment processes, while also striving to streamline operations, reduce costs, and maintain high product quality.

A Minnesota mine reduced copper and cobalt in its discharge using wastewater ion exchange, achieving compliance without chemicals and adapting to seasonal flow increases.

In order to expand operations and maintain a water balance in South Carolina’s wet climate, Nevada Goldfields’ Barite Hills gold mining operation required a treatment plant to handle its wastewater. At this mining site, the company extracts gold from soil using a high pH cyanide leaching solution. The process generated large volumes of cyanide and metal laden wastewater, which they had been storing on-site.

Soil and groundwater remediation projects often call for treatment of groundwater, soil vapor extraction condensate, soil vapor and other liquid and vapor streams for removal of volatile and semi volatile organic compounds. Xylem's Carbonair has provided thousands of STAT Low Profile Air Strippers, liquid phase and vapor phase carbon vessels for remediation systems over our 30 plus years in business.

A medical center in Georgia needed filtration for its three 400 ton cooling towers due to fouling/corrosion issues, silt and organic accumulation in the basins resulting in Legionella habitat buildup, and replacement of cooling tower fill due to plugged fill channels from unfiltered cooling water.

A leading Florida medical center features a state-of-the-art clinical diagnostics laboratory with a complete range of blood analysis services. The water requirements for new clinical analyzers installed in the lab was less than 10 mg/L total organic carbon (TOC) and conductivity less than 0.1 cm at 25 c. In order to meet these requirements, the medical center needed to update their water purification system.

A large healthcare products manufacturer in the United States needed to improve its environmental impact while substantially reducing excessive costs associated with municipal discharge and the operation of cooling towers.

A major medical center in Oklahoma was undergoing a very large instrumentation implementation for chemistry and hematology equipment with a strict timeline. The medical center brought in the regional Director of Outreach Laboratories to assist in the implementation in order to ensure a successful outcome.

In February 2020, the California State Water Resources Control Board announced revised drinking water Response Levels for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water. The new Response Levels (RLs) were set at 10 parts per trillion (ppt) for PFOA and 40 ppt for PFOS. The previous RL was 70 ppt for a combined total concentration for the two contaminants.

Norfolk Southern has a history of nearly two centuries of service that has linked communities and customers to the marketplace of the world. The railway company operates approximately 20,000 miles of rails and serves every major container port in the eastern United States while providing connections to other rail carriers.

The Commission for the Eradication and Prevention of Screwworm (COPEG), created by a cooperative agreement between the Republic of Panama and the United States of America, safeguards Panama and the rest of the countries in Central and North America from screwworm re-infestation.

Xylem was contacted by a leading US producer of fertilizers and pesticides and consultative services in the field of agricultural technology. Site managers for the company were seeking a solution for treating the rainwater runoff, which was contaminated with pesticides, to keep the contaminants from flowing into local water sources or leaching into groundwater.

Industrial process and wastewater can contain volatile organic compounds (VOCS) that can have a negative effect on the production process or downstream wastewater treatment processes. In these instances, it is often necessary to put treatment equipment in place to remove the VOCs.

In August 2010, an electroplating facility in California specializing in aircraft components was issued specialty permit levels for the reduction of cadmium in discharge wastewater. The current permit of 250 ppb was reduced to 70 ppb and the allowed cadmium levels are expected to move lower over the next few years.

Marathon Norco Aerospace located in Waco, Texas is one of the few manufacturers of rechargeable, nickel cadmium batteries for the aerospace industry. One of the production problems associated with the manufacture of rechargeable, nickel cadmium batteries is the use of a number of heavy metals.

Piney Point is the site of an inactive fertilizer facility. Following a bankruptcy filing by the parent company in 2001, the site was taken over by the State of Florida to oversee closure. Heavy rainfall and tropical storms in 2001 demanded immediate response to a potential breach of the site's pond dikes and hundreds of millions of gallons of acidic wastewater.

The site of a former zinc smelter in the eastern United States, whose soil and groundwater were contaminated after decades of zinc production, posed a significant treatment challenge: the water in the newly created retention ponds had a dissolved zinc level of about 10 ppm, well above discharge limits of <0.47 ppm.
