Water Resources Engineering (WRE) connects to economic, environmental, and social issues. Our student Erik Ranftle makes this connection in Lima, Peru. This current event was reported in the China Internet Information Center, on March 20, 2017 under the title, Peru hit by drinking water shortage, by the Xinhua News Agency. This is likely real news due to the independent report published on the New Tang Dynasty Television website about the lack of drinking water in Lima, Peru on March 20th, 2017, at here.

This news about water quality during the major flood relates to water resources engineering because the solution to the problem and future prevention will call for engineered solutions. The key message in this article deals with issues faced by WRE during flooding in Peru. The main issue that is faced is finding a way to provide drinking water to the 567,551 people affected by this natural disaster in Lima, Peru. The article talks about how Peru has a great many sources of drinking water. However, access to it does not reach its 30 million residents. During this flood, eight million Peruvians do not have drinking water and are obliged to rely on tanker trucks, usually not receiving enough for basic sanitary requirements. This is very important for WRE because has of March 20, 2017 death toll nationwide has climbed to over 70, with 170 injured and nine missing. It is important that a solution is found before more lives are lost in Lima Peru. The article was missing information on how to supply residence with the drinking water. The article mentions that there are some ideas to control the situation for example the Prime Minister has called on residents to take extreme care of the limited water and to ration its use, while expressing hope the strong rains will stop. The article does explain any method that could be taken right away to supply citizens with a new supply of drinking water. The plain seems to just want to wait till the flooding stops so that the SEDAPAL can begin processing water normally again.

Economic, environmental, and societal issues are related to the issues in Lima Peru. Floods relates to economic issues, because floods can destroy property. It leaves many people homeless. Floods also relates to environmental issues. This is because floods can deliver large amounts of pollutants stored on land into the receiving waters. This is what causes the drinking water to become contaminated. Floods also relate to societal issues. This is true because Floods can injure and even kill humans. Drowning is the main cause of people losing their lives during floods. The death toll nationwide has climbed to over 70, with 170 injured and nine missing in Lima, Peru as of March 20th 2017. Based on a report from Doocy (2013), floods are the most common natural disaster and the leading cause of natural disaster fatalities worldwide. There were 539,811 deaths, 361,974 injuries and 2,821,895,005 people affected by all floods between 1980 and 2009. The cause-effect between flooding and the impact to society occurs when water over flows the river tops usually due to excessive rain. As a result, people are exposed to fast moving debris and the possibility of drowning.
