From the source, we walked as far as we could along the above-ground portion of the distribution line, stopping to look at the “air relief valves” or simply put, holes drilled into the pipe with a piece of bamboo stuck in them to keep the water from geysering out. Malakai shared his concerns of the system with us: the source is often clogged with debris during rainstorms, and the distribution pipe is frequently damaged during Department of Public Works “road repairs”.
After taking samples from the source and the tank and GPSing the distribution line, we headed back to the Mission for lunch and paperwork. In the afternoon we took a trip to Sunny’s “Costco”, a warehouse-style wholesaler of canned foods and non-perishables. We purchased bleach to sterilize our sample results, and crackers and soda for our missionary friends who were up half the night being ill. (Given their miserable status, we have become even more fond of our bottled “Island Chill” water and have placed an order for a second case with Sunny).
Sampling Update: All Vunikura samples have tested positive for the confirmation of E. Coli. We are now running the Loa source and tank samples, and a full set of Mission tap water (fingers crossed).
Although there are virtually NO beaches with sand in this area (~sob~), we found a small stretch of grey sand outside of Sunny’s place. We grabbed a couple bag-fulls and are drying them in front of our rooms with the intention of performing a sieve analysis to determine if the grain size distribution is acceptable for slow sand filters.
Hey Justin! I love the blog (though having trouble with my comments, please exuse if this is the 3rd you've seen from me). I'm sorry to hear about the water quality problems these people are facing, but glad that you guys are out there to help. I'm looking forward to talking sustainable drinking water options when you come back! It's a humbling issue to face, way to be brave.
