This radium removal pilot study was conducted for the City of Bridgeton, New Jersey’s Well No. 19 treatment facility. The Bridgeton water system contains concentrations of radium and gross alpha in excess of the Maximum Contaminant Levels (MCL).
The City of Bridgeton is located in southern New Jersey, approximately 40 miles south of Philadelphia. It has a colonial heritage having been first settled by Quakers in 1686. Bridgeton is located in Cumberland County, and is the county seat with a current population of approximately 23,000. When the first bridge was built over the Cohansey River in 1716, the village became known as Cohansey Bridge. Before the Revolutionary War, Cohansey Bridge became known as Bridge Town, which was later mis-spelled as Bridgeton when the first bank opened and issued documents with “Bridgeton” printed on them.
The Well No. 19 treatment facility is one of three wells (the other wells being No. 20 & No. 23) that come together and are connected to Bridgeton’s distribution system. The water for Well No. 19 is drawn from the Kirkwood-Cohansey Aquifer (No. 20 from the Kirkwood-Cohansey and No. 23 from the Piney Point Aquifer) and has the highest level of radium between the three wells. The water drawn from the deeper Piney Point Aquifer is essentially radium-free. Well No. 19 is approximately 270 feet deep.
