We continued looking for sites to build the system in. We first traveled to a primary school in Lunzu. Five minutes walking from the school was an open water reservoir, which was their source of drinking water. We later traveled to Chikwawa. In order to get to Chikwawa Dr. Mkandawire drove us to a minibus station, we were on a minibus for about an hour, from where the minibus dropped us off a driver picked us up, and he drove us thirty minutes up the mountain, this drive up the mountain required a four-wheel drive. Once we got to Chikwawa we talked with the people that lived there, and they showed us their water source, which was a borehole. We were only able to get water samples at the school site at Lunzu, since I was not able to sterilize the bottles the morning we left for Chikwawa because someone was cooking sweet potatoes in the autoclave. The Lunzu sample showed 49 E.coli coliform forming units. We sat and tried to come to a consensus as to where we wanted to build the system. Many variables affected this decision, I thought, the school site in Lunzu was most suitable, not only because it was highly contaminated with E.coli, but because getting transportation there would not be a problem, unlike to Chikwawa, which required a four wheel drive. . The next day in the morning Aaron somehow, without having anyone agree on this, decided that we were going to build the system in Chikwawa. The rest of the week we were out on Blantyre shopping for materials to build the system. Aaron found a lodge that we would stay at for a whole week so we would not have to travel back and fourth every day from the Poly to Chikwawa. We were scheduled to leave the coming Monday and stay in Chikwawa the whole week building the system.

Brock emailed Dr. Loyo and Dr. Leataud telling them that we were leaving for the next week, and asking them if there was any procedure we should take before leaving. Dr. Leautaud responded to the email right away telling us to not leave on Monday, that she wanted to meet with us that Monday.
