Laboratory tests of water samples in New Orleans found it loaded with fecal material.
But while collecting water samples for this project, they keep their eyes peeled for their true passion, the dolphins.
Since 1996, he has tested 2, 866 water samples from wells that were previously labelled as being safe by field workers.
The area has been disinfected and water samples were taken for testing.
But scientists have detected Asian carp DNA in dozens of water samples collected farther upstream, some just a few miles from Lake Michigan.
Between September 2009 and October 2011, Jerde and his colleagues collected more than 2, 800 water samples from parts of the Great Lakes and tributary rivers.
He told me that the company has taken its own water samples in the Oriente, and has never identified a positive reading for hydrocarbon contamination.
New collected water samples from wells, tapping the aquifer on Argentinan and Uruguayan territory, were analysed on their main chemical parameters and compared with older data.
And what they're doing is they're taking water samples at different depths to try and establish the amount of hydrocarbons that are in at a particular depth.
Researchers analyzed water samples for DNA fragments released to the environment, called eDNA. They found silver carp eDNA in Iowa, where the fish are abundant, but none near St.
So if birds were the source, it seemingly would mean they feasted on carp, flew a long distance and excreted feces within a few hours of when the researchers collected water samples.
That's the conclusion of a group of researchers from the Centers for Disease Control (CDC), who collected water samples from 161 filters in public and private swimming pools, as well as water parks in Atlanta last summer.
In addition to a sea floor mapping project, the researchers will make chemical analyses of water samples that will help them determine the temperature, salinity and composition of a strong circumpolar current that flows around the boundary of the Arctic Ocean.
CNN: Nuclear sub dives under the ice to explore climate change
The Purdue team, assisted by the Indiana Department of Natural Resources and the U.S. Geological Survey, collected water samples containing Asian carp eggs in 2011 from sections of the river that were much shallower and narrower than had been considered necessary for spawning, Goforth said.
The monitors also serve as collection stations for precipitation, drinking water, and milk samples.
These detectors constantly monitor for signs of trouble and routinely collect air, precipitation, drinking water, and milk samples for analysis of radioactivity.
FORBES: Radiation No Threat To Silicon Valley, Santa Clara County Says
The U.S. Environmental Protection Agency's drinking-water regulations require that all samples test negative for E.coli.
Unless we can get samples in the water we can't identify what type of PIB this is.
The three-month Catlin Arctic Survey expedition will also take samples of the water, snow, ice and air.
In 2009 New Scientist writer Michael Reilly "hacked" a colleague's genome using samples from a water glass.
Likewise, in 153 samples of drinking water, only 36 had any radioactivity.

This is effective: samples of the air above breaking water show high concentrations of minute organisms normally found in the water.
Officials say water supplies have not been affected so far and they are closely testing samples from the river, but the public remain wary.
Torbay Council said initial samples taken by the Environment Agency after the sewage pumping showed bathing water quality had not been affected.
BBC: Torbay sewage pumping 'not affecting beach water quality'
Wednesday also marks the start of the bathing water season during which teams from Natural Resources Wales will collect 2, 000 samples over the season from 100 designated beaches.
Data retrieved from HICO have been validated with data collected from samples collected on the ground and used to develop algorithms to map indicators of water quality.
FORBES: New Crew Launches On Fastest Trip Yet To Space Station
The researchers looked at the different types, or isotopes, of oxygen atoms trapped in the samples and, using a well-established technique, were able to infer water temperatures at the time the organisms built their shelly parts.
According to NPR, because the researchers only analyzed the samples for genetic signatures of different pathogens, they couldn't determine whether the bugs were alive, and potentially reproducing in the water, but there were no pool-related diseases reported in Atlanta during the summer the samples were gathered.
