Researchers at École Polytechnique Fédérale de Lausanne (EPFL) have developed a robotic eel that can efficiently scan a source of water for pollution and wirelessly deliver the data it gathers in real time. The robotic eel mimics its namesake by swimming through the water with a similar locomotion to find and follow signs of pollution.
Water quality samples are typically taken by hand on a regular schedule, but the process is slow and only represents the quality of the water at the spots where it was sampled. The a[sic] team of robotic eels could more regularly take measurements and cover the expanse of a body of water.

The robotic eel is outfitted with sensors that make it able to test the water for changes in conductivity and temperature as well as signs of toxins. The robot is made of several modules, each containing a small electric motor and different sensors. The modular design allows researchers to add or take from its length and change the robot's make up as needed for each task.The robot features traditional sensors measuring temperature and conductivity, but there are also biological ones comprised of bacteria, crustaceans and fish cells that detect the presence of toxins. The researchers observe any changes to the organisms when placed in the water. For instance, the bacteria will luminesce when exposed to even very low concentrations of mercury. Luminometers measure the light given off by the bacteria and that information is transmitted to a central hub for analysis.

I , for one, welcome our new robot overlords.
oops, wrong site.
As the cost of developing this sort of robot comes down, I do hope that it makes it more accessible to scientists and local government to do this exact kind of repetitive on going environmental monitoring.
