steady trickle of water. Water appears clear. Black squirrel, sighted and a couple of pieces of litter. Summer drought.
slight smell of chemicals. Cloudy cool day after a week of high to mid-high temps. No rain for past 10 days. new wetland plants establishing nicely, lots of invasive ground cover, all are providing shade and some water interception.
Water exiting storm pipe. Greyish silt coating bottom of pool. Conductivity metre reads 7°C water temperature.
Hi turbidity reported by resident just before 12 PM.
Water clear today. Sediment spill recorded yesterday. Water temp with handheld conductivity metre is 8.5°C.
very small trickle of water discharging. water very clear.
In the past water temp taken from EC meter. Instant read digital registers nearly 1 degree lower, which is believed more accurate. I will use air temp fr digital from now on.
Conductivity confirmed by measuring in different spots of pool. EC is 150 at 16.9 celsius.
small trickle from pipe. low water, iron oxide (?) staining. pool filled in with sediment.
very low water flow. pool is more filled in with sand. trickle from pipe, then a big flush.
Water is turbid. Sediment has been deposited. This outfall has been the source of multiple sediment spills from the community centre construction site in the past 4-5 weeks. One leak on the site has yet to be identified, there may be continued turbidity during rainfall until it is found and fixed.
Started using pH meter instead of test strips, reading is 8.1, substantially higher than test strips. Have now deleted pH value as I suspect the meter was incorrectly calibrated.
Previous day: heavily turbid water during heavy rains. Suspected erosion from construction site (Harry Jerome construction). In the past month, there have been multiple contamination events: cement wash 3 weeks ago and laundry soap one week ago.
