Old Gasoline Leak Puts Mora City Water at Risk; MPCA Rests Cleanup Technology

The Minnesota Pollution Control Agency (MPCA) will test petroleum cleanup technologies at the former Town & Country Oil site in Mora in an effort to continue preventing contaminants from migrating to nearby city water wells. Gasoline and diesel fuel leaked into the ground at the site, located at the southwest corner of Maple Avenue and Highway 65, some 15 years ago.

Bottled, Boiled or Filtered Water: How to Get Pure Drinking Water in India?

In many places, you can’t drink tap water in India directly and safe or pure drinking water is a big concern for most of us. Every year 37.7 million people in India are affected by waterborne diseases due to contamination of water by bacteria (E coli, Shigella, Vibrio cholerae), viruses (Hepatitis A, polio virus, rota virus) and parasites (E. histolytica, Giardia, hook worm). Luckily, antibiotics and other medicine can treat most water-borne diseases. What is more worrying is the presence of arsenic and other heavy metals such as cadmium, zinc and mercury.

The Rundown on Water Pollution in the Tijuana River Valley

California’s coastal border with Baja region is particularly vulnerable to rains. Storms send muck and sewage down canyons, into channels, and finally gets discharged into the Tijuana River and the Pacific Ocean, prompting pollution warnings and beach closures in both countries. Contamination and cross-border pollution has been a fraught topic for years, but never more so than now, ahead of a rainy season in which a historically powerful El Niño appears imminent.

New Sensor Detects Water Contamination in Real Time

A group of students from the Technical University of Denmark have created a sensor that they say can detect bacteria in water instantly, on the spot. Developed through spin-off company SBT Aqua, the sensor utilizes a technique known as impedance flow cytometry.

Groups Work to Address River Pollution

Swim areas in Lake Isabella do not have high levels of E. coli, but village officials are working to find the source of the bacteria that is found in many water sources in mid-Michigan. Village officials have been working for two years with the Central Michigan District Health Department to monitor E. coli in the man-made lake that was a section of the Chippewa River before a dam was built.

IG Questions Water-Quality Payoff from Pricey Sewer Upgrades

It’s unclear whether the billions of dollars that U.S. EPA has required cities to invest in sewer upgrades are yielding water quality improvements, the agency’s inspector general concludes in a new report. The agency has been working since 1998 to curb so-called combined sewer overflows by forcing cities to bring their sewer systems into compliance.

This New Technology Converts Sea Water into Drinking Water in Minutes

Developed by a team of researchers at Alexandria University in Egypt, the desalination technique called pervaporation removes the salt from sea water and make it drinkable. Specially made synthetic membranes are used to filter out large salt particles and impurities so they can be evaporated away, and then the rest is heated up, vapourised, and condensed back into clean water.

Models For Predicting Source Water Pollution: Hopelessly Flawed?

Newly public predictions about potential source water contamination are casting doubt on models used to anticipate how polluted water may flow from mining operations. The problem centers in Minnesota, where a proposal for the state’s first copper-nickel mine has remained under environmental review for a decade.
