Long Island American Water, which supplies water to 200,000 Nassau County residents, has opened a new iron-removal plant in Malverne.

The new, $7.5 million plant allows the company to reopen two wells that had been taken offline because their water was too high in iron, the company said. The official opening was last week.

The plant will allow the company to pump 4 million gallons a day of filtered water.

"Iron intrusion is a challenge in Long Island and this new state-of-the-art plant provides a much-needed solution to help us provide water that meets or exceeds both EPA standards as well as our customers' standards," William Varley, president of New Jersey based parent company American Water, said in a statement.
