A report from CDM Smith found 97% of lead filters in the city of Newark, N.J., effective.
Newark, N.J.'s, water consultant, CDM Smith, released a report that discovered the city's lead filters are 97% effective according to NJ Spotlight.
About 1,600 separate samples were collected from over 300 residences located in areas served by the Pequannock water supply.
Of 198 filters tested, all but five reduced lead to acceptable U.S. EPA levels. The report also found that when residents let the tap run for five minutes, the filters worked 99% of the time.
The EPA agreed that the filters were working and lifted its bottled water recommendations.
The report found that about a quarter of the filters tested were non-viable because they were improperly installed or maintained, however, according to NJ Spotlight.
“These findings emphasize the importance of Newark's recommendation that residents both flush with the filter in the off position for at least five minutes and filter water with a properly installed and NSF-certified filter prior to use for drinking and cooking, until such time as the new corrosion control treatment becomes fully effective,” said Gov. Phil Murphy in a letter.
Essex County’s $120 million loan will allow the city to embark on a major lead pipe replacement effort, which will take a number of years, according to the letter.
The city says more than 2,700 underground lead service lines have been replaced thus far, reported NJ Spotlight.
The state environmental protection commissioner estimated that the cost could be as much as $3 billion. The plan also would require voter approval. The New Jersey Department of Environmental Protection has made $12 million in loans available to Newark from the Safe Drinking Water State Revolving Fund, reported the letter.
