EARTH: Managing the seismic risk posed by wastewater disposalApril 19, 2012
What steps can we take in order to safely practice wastewater injection? In the April issue of EARTH Magazine, Mark D. Zoback, professor of geophysics at Stanford University puts forward five steps that can be taken to reduce the probability of triggering seismicity associated with fluid injection. Zoback argues that through proper study and planning prior to injection, careful monitoring in areas where seismicity might be triggered, and careful training of operators and regulators will help to manage the seismic risk posed by wastewater disposal.

Atmospheric release of BPA may reach nearby waterways
Water contamination by hormone-disrupting pollutants is threatening water quality around the world. Existing research has determined that harmful concentrations of Bisphenol-A (BPA), a chemical used in consumer products such as plastic food storage and beverage containers, have been deposited directly into rivers and streams by municipal or industrial wastewater.
Disposable wipes are costing sewage systems millions of dollars
Several class-action lawsuits filed recently against the makers of flushable wet-wipes have brought to light a serious -- and unsavory -- problem: The popular cleaning products might be clogging sewer systems.

A new approach to wastewater treatment may be key in efforts to reduce, reuse, and recycle. Moreover, it can be profitable.
New technique shows shale-drilling additives in drinking-water taps near leak
Substances commonly used for drilling or extracting Marcellus shale gas foamed from the drinking water taps of three Pennsylvania homes near a reported well-pad leak, according to new analysis from a team of scientists.
Megacity metabolism: Is your city consuming a balanced diet?
New York is an energy hog, London and Paris use relatively fewer resources and Tokyo conserves water like a pro. These are just a few of the findings from a new study on "megacity metabolism"--the world's first comprehensive survey of resources used and removed in each of the world's 27 largest metropolitan areas.
Diabetes drug found in freshwater is a potential cause of intersex fish
A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish -male fish that produce eggs.
Likely cause of 2013-14 earthquakes: Combination of gas field fluid injection and removal
A seismology team led by Southern Methodist University (SMU), Dallas, finds that high volumes of wastewater injection combined with saltwater (brine) extraction from natural gas wells is the most likely cause of earthquakes occurring near Azle, Texas, from late 2013 through spring 2014.
Combined sewer systems lead to risk of illness after heavy rains
Consumers whose drinking water can be contaminated by the release of untreated wastewater after heavy rains face increased risk for gastrointestinal illness, according to a report in the journal Environmental Health Perspectives.
Rice U. study: Algae from wastewater solves 2 problems
In one of the first studies to examine the potential for using municipal wastewater as a feedstock for algae-based biofuels, Rice University scientists found they could easily grow high-value strains of oil-rich algae while simultaneously removing more than 90 percent of nitrates and more than 50 percent of phosphorous from wastewater.
Notre Dame researchers develop computational model to simulate bacterial behavior
University of Notre Dame applied mathematician Mark Alber and environmental biotechnologist Robert Nerenberg have developed a new computational model that effectively simulates the mechanical behavior of biofilms. Their model may lead to new strategies for studying a range of issues from blood clots to waste treatment systems.
