nitrate & selenium in municipal waters

Nitrate is one of the most widespread groundwater contaminants in the United States, originating from agricultural operations such as fertilizer application and accumulation of livestock manure. Excessive levels of nitrate in potable water can lead to serious health effects, leading the EPA to restrict levels of nitrate to 10 mg/L in drinking water. The nitrate issue in the US and abandonment of impacted wells has left many communities without a safe, reliable drinking water source. This results in a need for a cost effective and sustainable solution to treat contaminated drinking water supplies.

Selenium occurs naturally in many ecosystems and has been identified as a target contaminant within municipal water treatment. Common drinking water treatment technologies of reverse-osmosis and ion-exchange create concentrated waste streams that can contain elevated levels of selenium and nitrate. In many cases, these concentrated waste streams require further treatment prior to discharge.
