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.
Rather than seeing the world’s water problem as one global crisis, author and journalist Marq de Villiers prefers to break it down and suggests there are solutions best taken up locally. His view is outlined in a new book called “Back to the Well: Rethinking the Future of Water.”
What makes Ron Manuel’s driveway so special? It’s made out of permeable concrete. When it rains, the water drains right through it and into the soil below.
CORPUS CHRISTI – City crews are making progress installing backflow preventers in Flour Bluff. Those devices are being installed in homes with wells to prevent an E-Coli scare like the one we had a couple of months ago.
Water technology and monitoring company Modern Water has launched a range of oil in water monitoring products in the US and has supplied a Multisensor 1200 volatile organic compound (VOC) monitor to Glendive Water Treatment Plant in Montana to ensure safe drinking water for around 6,000 people.
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.
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.
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.
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.
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.
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.
