OHES Attendances Winterbourne STW 27.03.22 – 27.03.24.xlsx

And here’s the conversation I had with ChatGPT about this data…

I have received the attached spreadsheet of water quality data from Thames Water, the local water company, based on samples they have taken at various points along a stream that runs through the village where I live in Berkshire, England and through my property. Please try to identify what they are actually measuring. Please also try to identify any trends over time and any unusual or extreme readings.

The spreadsheet contains the following columns with data measurements from various locations along a stream:

1. Run Date & Time: The date and time when the measurements were taken.
2. Location: Identifies the specific sampling location, such as upstream, ingress, or downstream points.
3. Distance (): The distance in meters from a reference point (though the specific reference isn't specified in the column name).
4. Time: The time of day when the sample was collected.
5. DO(%): Dissolved oxygen percentage in the water.
6. NH3(mg/l): Ammonia concentration in milligrams per liter.
7. NH4(mg/l): Ammonium concentration in milligrams per liter.
8. Grid reference: The geographical grid reference for the sampling location.

Next, I'll look for any trends over time and identify any unusual or extreme readings within the data. Let's start by plotting trends for dissolved oxygen, ammonia, and ammonium concentrations over time.

Here are the plotted trends for each measured parameter over time:

1. Dissolved Oxygen (DO%): The dissolved oxygen levels show some fluctuations but generally remain within a stable range. There is no clear downward or upward trend, which suggests that the oxygen levels are somewhat consistent, though individual spikes or drops might be influenced by specific environmental conditions or events.
