Envirogen has been awarded a contract to install a MinX Regenerable Ion Exchange (IX) groundwater treatment system at a mobile home park in California. The purpose of the MinX System is to produce safe drinking water from groundwater polluted by selenium and arsenic at levels that exceed local drinking water standards. Envirogen was appointed in March 2024 to treat the park’s groundwater resource to less than 80% of the State of California drinking water maximum contaminant levels (MCLs).
The treatment system processes water from more than one well and will be fully installed and commissioned by the end of 2024, with the target to provide drinking water to the park community by early 2025.
“Ultimately, the life-cycle costs for the MinX regenerable IX unit were shown to be the best option for the client,” says Dr. Todd Webster, Vice President, Envirogen.
MinX technology was developed by Envirogen to meet challenges presented by groundwater containing multiple contaminants, variable water treatment volume and start-up/shut-down type operations. Its proprietary multi-bed ion exchange configuration allows it to lower operating costs by processing higher water volumes than traditional IX systems, without compromising on water quality.
The design enables quick installation and very low waste rates, and includes remote monitoring and communications for rapid, effective response by field service technicians.
Reliable and robust
Dr Webster comments, “California groundwater resources continue to be impacted by potentially toxic metals such as arsenic and selenium. Property owners dependent on groundwater for their water requirements are turning to effective technological solutions to provide potable water to their residents.
“The Envirogen MinX Regenerable IX unit is such a solution. Its efficient treatment technology provides a remedy that’s reliable, robust and has the lowest life-cycle treatment costs. Above all, and in this case, it will ensure an uninterrupted and safe water supply for the park residents.”
Prior to the award of the contract, Envirogen performed extensive option engineering for the client, reviewing multiple potential treatment options to produce potable water at the park as cost-effectively as possible.
Important step
A park spokesman said:
“The award of the new groundwater selenium/arsenic treatment plant to Envirogen is a very welcome and important step for the park. After an extensive evaluation of treatment options with Envirogen, management is very confident that the Envirogen MinX ion exchange system delivers both the best value and best performance technology.
“Speed of delivery is crucial, with the design and construction of the facility being underway in Q1, 2024 for completion later this year. The award is critically important for us to supply a safe supply of water to residents for years to come.”
