Heavy Rainfall Doesn’t Always End Water Shortage
Unless water can replenish underground aquifers, the danger remains It may seem counterintuitive, but heavy rainfall - even extreme flooding - may not end a drought or water shortage. According to the United States Geological Survey, flooding and drought are related much as medicine and illness are. A single dose of medicine may temporarily relieve symptoms, but a cure often requires a long ...

Fluence Solutions for Aquifer Recharge
Fresh water can be stored underground in aquifers, but many water sources must be treated before that can happen Growing populations worldwide have become increasingly dependent on groundwater, and human activities are now depleting aquifers - the underground formations where groundwater is stored - faster than natural systems can recharge them. This depletion can damage the environment. As ...

Salt Water Creeps Onto East Coast
Seawater is rapidly intruding into coastal aquifers, but alternative water sources can slow its progress On the East Coast of the United States, seawater is creeping inland, contaminating fresh water in underground aquifers. This intrusion is not uncommon. Since salt water has a higher density than fresh, it sinks to the bottom of the water table, often without affecting the fresh water above. ...

This World Water Day is leakage the elephant in the room?
This World Water Day as we ponder why precious groundwater is suffering the same fate as our lakes and rivers, FIDO CEO Victoria Edwards asks whether plundering even more of this invisible resource is right when we’re already leaking so much. Is leakage the elephant in the room? Water is essential for all life on earth. Few of us need reminding of that fact. Certainly not Vladimir ...

Regulatory Aspects of Direct Potable Reuse in California
Introduction California's water supplies are derived from a variety of sources, including local and imported surface water, groundwater, desalinated seawater, and recycled water. Water resources are becoming limited due to population increases, droughts, and reductions in imported water allocations. Furthermore, global climate change may exacerbate the problem in the future. Water recycling for ...

Fighting saltwater intrusion into groundwater supplies
As freshwater supplies around the world diminish, human intervention is needed to protect existing sources to slow the onset of water scarcity. One ongoing struggle is to preserve the water in underground aquifers, which cities often rely on for drinking water. Intrusion of saltwater into these underground supplies is rendering them unfit for consumption or irrigation. The rock and soil that ...

Bottled versus tap water fact sheet
Where does bottled water come from? Those beautiful mountain illustrations on water bottles are often very far from the true source of the water inside. Bottled water sources can be hard to track down, as bottled water manufacturers are not required to disclose where the water comes from or for that matter, what’s in their water. In fact, the best indicator of what kind of water is in the ...

Australian Cities Adopt Wastewater Reuse
Getting past old attitudes is a key to keeping up with growing water needs Potable reuse of wastewater has gone by many different names, some of them unflattering, like “toilet to tap.” Despite the clear benefits of water reuse, this so-called “ick factor” has slowed the adoption of technology that can transform wastewater into drinking water. Indirect potable reuse ...
