Petri Dish Showing Active Bacteria Colonies (Large Purple and Pink Dots) |

The first test result is in for the water filter, and it shows that we have bad bacteria in the water. I know this because of the purple and pink dots growing in the petri dish. Each one represents an E-coli bacterial colony. The goal is to reduce these colonies to nearly zero.
This was to be expected because I took the sample yesterday evening before the schmutzdecke, which is the biological killing zone at the top of the sand, had formed. So even though the water had passed through the sand and the gravel, the sample at this time is nearly the same as unfiltered Waghi River water.
I am now running the filter to clean out the bad bacteria. We will take our next test this Friday and compare results. Lord willing the water will be cleaner.
Keep praying.
P.S.
One small piece of unrelated news is today I was interviewed on PNG's NBC radio. This station is equivalent to National Public Radio in the US. I was asked questions pertaining to the topic of biblical ethics. The 15-minute session went well, and hopefully the Lord was honored.
