Wey Natural River

Total coliforms above testing range of >2419.6

Both Total Coliforms and E.coli read >2419.6CFU/100mL. Recommend dilutions for next reading.

I was able to sample directly from the pipe today due to a lowering of the river level. There was a decent flow of water coming from the outflow pipe. I noticed a washing machine smell and a small amount of bubbles as the pipe water was taken downstream. When I'm next down at Unstead Wetland Reserve I will need to cut back some of the vegetation at this sampling location which has grown quite a bit since I visited last month.

The river level was above the outflow pipe so a sample taken directly from the pipe was not possible. The river level was the highest I have seen it.

The river was at its highest level since I started testing. Yesterday there was persistent rainfall for much of the day. I was unable to sample directly from the pipe which was submerged.

A small dead tree, covered with ivy, had fallen in front of the outflow. At the time of taking the sample water was surging from the pipe. After the surging had ceased there was some foam on the surface of the water. The sample was a mixture of pipe and river water.

The River level was above the outflow pipe, so it was not possible to take a sample directly from the pipe which I have been doing so far (testing at this location is focused on what is entering the river directly from the sewerage treatment works)

Bubbles were produced following a surge of water from the pipe. There was a washing machine smell.

Note at this location I attempt sample from the pipe/where the pipe water meets the surface of the river. Water level, colour & clarity refer to the river rather than what is flowing out of the pipe. The water level was higher than average but not breaching the river bank. There was a steady to strong flow from the pipe.

I have not answered most of the qualitative questions above due to sampling straight from the pipe. The river water directly below the pipe was brown/opaque and there was some foam a little way downstream. The estimate of water flow is replaced by flow from the pipe which can be slow, steady or surging.
