Last summer, the city of Toledo, Ohio, made headlines when a do-not-use order affecting 400,000 residents was issued due to microcystin contamination. Caused by a bloom of blue-green algae in Lake Erie, the contaminant forced people to turn to bottled water for all of their water needs. John Keener of Toledo Water Conditioning shared his experience with WQP Managing Editor Kate Cline.
Kate Cline: What is microcystin? How does it affect human health?
According to the United Nations, 10 years from now there will be more than 37 megacities around the world with populations of more than 10 million. Four of those cities will be in North America: New York, Los Angeles, Chicago and Washington, D.C.-Baltimore.
Aging infrastructure’s effects on safe urban drinking water delivery
As we get into the full swing of summer, water is often the focal point of fun, whether that means a trip to the local pool, a water balloon fight in the backyard or a day boating on a lake.
It also means that it has been almost one year since Toledo, Ohio’s microcystin contamination crisis. The cyanotoxin, a result of a bloom of blue-green algae in the city’s Lake Erie source water, resulted in a do not drink or boil order being issued on Aug. 2, 2014, affecting 400,000 people in the Toledo metropolitan area.
Researchers have used the California mouse species to prove that offspring born to parents who are exposed to BPA receive decreased parental care by both the mother and father
Biparental care of offspring, or care that is administered by both parents, occurs in only a minority of species, including humans. Past studies have shown that maternal care can be negatively affected when females are exposed to endocrine-disrupting chemicals including bisphenol A (BPA); however, no studies have shown how this chemical can affect maternal and paternal care when both parents are exposed.
Extensive additional contamination was discovered after the 1996 cleanup plan
The U.S. Environmental Protection Agency (EPA) is proposing to modify a cleanup plan originally issued in 1996 to address soil and groundwater at the AVX property at the Olean Well Field Superfund Site in Cattaraugus County in Olean, N.Y.
Water that enters the soil and flows downward likely will be used again by society. The most common scenario would be that the downward-flowing water recharges the groundwater reserves that are then used as a source of drinking water or for irrigation. Groundwater also often has a hydrologic connection with surface water bodies, so the characteristics of the groundwater can influence aquatic habitats in a lake or river, which then may be used as a source of drinking or irrigation water.
Soil’s benefits as a filter for a variety of contaminants
CDC offers tips to help swimmers stay safe in various swimming venues
When most people think of norovirus, they think of people marooned on a cruise ship with raging stomach and intestinal illness, unable to leave their cabins. However, an outbreak at an Oregon lake underscores that swimming also can put the public at risk of catching this disease. Fortunately, following a few easy and effective steps can help maximize the health benefits of swimming while minimizing the risk of getting sick.
Our bodies of water are constantly sustaining the impact of ecological and environmental changes. Our municipalities are treating water from these sources with harsh chemicals and delivering it to communities. Increasingly aware of these facts, consumers are demanding point-of-use filtration products that ensure that their families are drinking safe, clean water. HaloPure technology was created with these consumers in mind.
NFS is a nanofiltration (NF) membrane formulated to deliver sulfate rejection and flux performance in sulfate removal applications. In addition to exhibiting high mechanical strength and durability, the membrane provides a 30% increase in flux efficiency and more than 99.5% average sulfate rejection when tested under typical seawater operating conditions. This type of NF technology is ideal for enhanced oil recovery during water flooding processes through the prevention of scaling and oil well souring.
AdVantEdge Medallion Series POE systems by AdEdge Technologies are ideal for whole-house arsenic treatment. They require no chemicals and no regeneration for low maintenance, worry-free arsenic removal for the entire household. This economical and effective whole-house treatment employs an adsorption process using Bayoxide E-33 granular ferric oxide to provide the best arsenic removal performance of any available technology, and is considered the standard in the industry.
