As the pumps no longer function, what would they be testing?
Testing, or spraying? THAT is the question! Natural precipitation might collect in these old village water sources, then become stagnant, to attract the pesky mozzies laying their larvae in them?
The Water Inspectors might possibly be doing water quality testing AND anti-mozzie spraying, depending on the location. For example, imagine a natural spring where hikers and ramblers like to take a taste of the water flowing out from the hillside.
What if a farmer further up the hill has dumped a load of fertilizer onto his land, and the chemicals then sink down through the soil and enter the same natural underground water course feeding the spring? Think about it, please- it happens!
Now that grb and Max appear to have solved this enigma, are you planning to add an update page to your 'Tags' Blog, Dom?
