At Apps Laboratories we measure a range of factors in water samples. Some like dissolved metals can be compared directly to the Australian Water Quality Guidelines. Others like salinity indicate what the water can be used for for example depending on the salt tolerance of irrigated crops. More often we want to give the landowner…

Boosted reverse osmosis filter for farms
One of the problems with many homes in rural areas is that there is not enough pressure from pressure pumps to run a reverse osmosis filter system. Reverse osmosis filters work by pushing water against a very fine membrane. Only a proportion of the water, usually 1/4 to 1/3 gets through, leaving behind most salts…
Trip to Mt Erica
Last weekend I joined a few of my ex Rover friends from the Yallourn Capt Hurley Rover Crew on a trip up “The Mountain”. The mountain is Mt Erica in Gippsland. Most of us are in our late 50’s or early 60’s. We have mostly known each other for over 40 years. Our numbers were…
ORP in water – what does it mean?
Recently a couple of bore water samples came through the lab. By coincidence although they came from very different locations they had some distinct similarities. These were elevated dissociated carbon dioxide, elevated soluble iron and elevated manganese. But they both had another similarity – low ORP or redox value. The sample with the highest metal…
What’s in water?
Water testing is a little bit like problem solving. Most people want to know if there are any underlying issues that may affect their water quality. For example if there are higher than expected numbers of bacteria, if there are dissolved metals present or if there is any contamination from organic chemicals. Most test results…
