The colour of the soil is dark brown and most of the samples are sandy in texture which is why I think the parent rock is sandstone, some may be mudstone though.
The creek isnt very polluted at all, I only found evidence of part of a plastic bag at one sample spot. There is a lot of rust in the water though, I think it comes from the drainpipe which flows into the creek. I do know that there is pollution further down from where I tested, garbage mostly.

all of your results are looking good and it's great to see well-organised tables that you can later just copy and paste into your final report. Don't forget to add units to your phosphate readings.
