How Things Work

Water for drinking is a necessity typically associated with high standards. As such, we adopt measures to ensure we drink the kind of water we want. Some people feel safe and comfortable drinking water straight from the tap; others choose to only drink bottled or filtered water. Is one method better than the other?
In the United States, the Environmental Protection Agency (EPA) has set up certain standards for drinking water that ensure that tap water will be “safe to drink for healthy people,” according to the EPA publication “Filtration Facts.” These standards are among the highest in the world, and they set levels for contaminants that can be found in water; the maximum levels are low enough that they will not harm healthy people.
Generally, to meet these standards, water treatment plants follow a series of processes to filter water. Water is first extracted from either above or below ground; water coming from underground tends to be cleaner because it has been sheltered from many pollutants. Extracted water then goes through the process of coagulation: Alum, iron salts, or organic materials are added to the water, and the mixture is left to settle. The added particles attract dirt and other impurities to form big sticky particles called “floc,” which slowly settle.

Freehold addressing filter issue
31.12.69
FREEHOLD — Municipal officials have introduced an ordinance that seeks to appropriate $30,000 from Freehold Borough’s water-sewer utility capital fund surplus in order to repair filter No. 3 at the town’s water treatment plant on Waterworks Road.
The ordinance was introduced at a Borough Council meeting on Oct. 3. A public hearing and second reading of the ordinance will be held at an upcoming meeting, to be followed by the governing body’s vote on the ordinance.
Borough Administrator Joseph Bellina said a pressure sand filter appears to be leaking and losing sand.
The failure makes it difficult for that particular filter to remove iron from the water, but the overall system has not been impacted because other filters are continuing to remove iron from the water, Bellina said.
The leaking filter was installed in the 1940s, according to Bellina, who said it could be decommissioned without causing a negative impact on the iron filtration system. He said if two filters were not operational, that situation might place a strain on the system.
