Recirculating powdered activated carbon (PAC) is a water treatment process directed towards removing organic and emerging contaminants. It doesn't generate a brine waste stream and uses less power than reverse osmosis (RO). While the process is relatively new to the U.S., successful pilot testing…

For watersheds with sparse stream gauge data and regulatory structures (as in reservoirs), watershed modeling remains the only method available to compute discharge values—although difficult to calibrate. Statewide regression equations published by the U.S. Geological Survey cannot be applied for…

Benjamin Franklin once said, “When the well runs dry, we know the worth of water.” Mr. Franklin could have just as easily added that we’ll also know the value of flood protection when the levee fails. Aside from air, water is perhaps the most fundamental element for all living things, and yet we’ve…

Where flat terrain exhibits unconfined floodplains, a dam breach or natural flood wave can potentially travel in all directions since water is not confined to a narrow valley. By applying 2-D hydrologic and hydraulic models, mathematical calculations are used to route flows in eight potential…

Recent regulations, specifically LT2 IESWTR, are pushing water providers towards membrane filtration. Until now, there has only been one real membrane filtration option–polymeric membranes. Ceramic membranes for drinking water offer an alternative, but are relatively new in the marketplace.…

The New Jersey Department of Environmental Protection (NJDEP) assigns an ecological classification to each stream in New Jersey. The highest classification is called Category 1 (C1). The areas located within 300 feet of C1 streams are called Special Water Resources Protection Areas (SWRPA). These…
