The Portland Water Bureau said Tuesday it will switch back to delivering customers water from the near-pristine Bull Run Watershed on Wednesday after serving only groundwater for about a month.
The office switched to serving 100 percent […]

The Portland Water Bureau will ask the City Council to try treating the area’s drinking water to reduce the amount of lead leaching from pipes, a recommendation that pivots from the city’s previous insistence such treatment was unnecessary.
Portland’s water from the Bull Run watershed has a low enough pH level that it can leach lead from old pipes and fixtures. Adding chemicals that don’t harm human health can make the […]

Portland’s water bureau detected a trace amount of cryptosporidium parasite in a test of drinking water from the Bull Run watershed again Monday.
After four straight years not finding any cryptosporidium during weekly water samplings, the city has now detected the parasite four times this year, raising the specter that the city might have to build an expensive treatment plant.
This week’s finding does not raise immediate alarms for human health, officials said. The […]

NESPELEM—In early December, a number of news agencies reported seaborne radiation from Japan’s Fukushima Nuclear plant was detected in the Pacific Ocean along on the West Coast.
The plant, which first leaked radiation into the Pacific in 2011 following a massive earthquake and tsunami that killed nearly 16,000 people, is feared to still be contaminating the ocean.
The impact of the radiation in the Columbia River—and on migratory salmon that spend their developmental years […]

The port is asking the court […]

AUG. 17, 2016 The dunal lakes of the central Oregon Coast are, from a geologic perspective, ephemeral, destined to eventually fill with silt or breach their natural impoundments and drain to the ocean. Coastal residents have a responsibility, as well as a strong self-interest, to ensure that the lakes’ remaining lifetimes are measured in millennia rather than decades.
Siltcoos Lake offers a glimpse of what might lie ahead. It’s the largest of the coastal lakes, at 3,164 acres, and also […]

on August 04, 2016 at 2:18 PM, updated August 04, 2016 at 2:19 PM Researchers from The Ohio State University have uncovered some previously hidden sources of ocean pollution affecting more than 20 percent of the coastline of the continental United States, with a particular threat found for the waters off the Pacific Northwest.
The study, led by assistant professor of earth sciences Audrey Sawyer and published Thursday in the journal Science, marks the […]

A monitoring well installed after last month’s train derailment near Mosier has detected oil contamination in the ground water.
The state Department of Environmental Quality told Portland station KATU that drinking water is not affected in the Columbia River Gorge town because those wells are uphill from where the oil train derailed June 3.
The agency said Wednesday that four monitoring wells were installed after the wreck, and one revealed significant oil contamination.
DEQ plans to install a treatment system […]
