The purpose of this Written Assignment #6 is to explore promising solutions that aim at improving affordable access to safe drinking water or sanitation services in communities that may have challenges in accessing them. For this assignment, identify one promising solution that has been implemented somewhere in the world.  The solution you choose can be, for example, a low-cost technology, product, implemented good practice, education/training program, adopted policy, or any solution-oriented strategy.     
In this approximately 2-page write-up, address the following: 
1. Describe the promising solution that you identified.
2. What are the strengths and weaknesses of the solution in relation to affordable access to safe drinking water or sanitation service? 
3. Is there any kind of human or environmental health impact information available after applying/implementing the solution? If yes, what kind? 
4. How feasibly can the solution be implemented or applied in different circumstances or environments? 

In the area where you live, what species are invasive? How did they get there? How are they affecting the native species in your area? What management techniques are used to diminish these effects? Use resources from the Internet, including www.invasive.org, www.issg.org, and www.invasivespeciesinfo.gov, to identify species.
