The chart, titled 'Ammonia Levels Over Time by Location', provides a clear view of how the ammonia concentration has changed from November 2024 to August 2025.

Here are some key observations from the data:

  • AberCorran: This location showed the highest initial ammonia reading in December 2024 but has since dropped to lower levels, with a slight increase in August 2025.

  • Culvet: This location consistently had an ammonia level of 0 mg/L until a significant spike in August 2025, reaching 0.12 mg/L.

  • Horsepool Bridge: This location shows a consistently low but present level of ammonia from March 2025 to July 2025, before dropping back to 0 mg/L in August 2025.

  • GlanCorran: This location had a peak ammonia level in January 2025 before dropping and remaining low.

  • Other Locations: Most other locations, including Llandawke, Broadway Cav Park, Horsepool Rd Tributary, Hills Farm, and Newbridge Bridge, have shown very low or no detectable ammonia throughout the period.

It's important to remember that in most healthy aquatic systems, ammonia levels should ideally be close to 0 mg/L (or ppm). Elevated ammonia can be toxic to fish and other aquatic life.

Here is the line chart for the nitrate readings you provided.

The chart, titled 'Nitrate Levels Over Time by Location', visualizes the nitrate concentration for each site from November 2024 to August 2025.

Here are some of the trends from the data:

  • Highs and Lows: GlanCorran and Horsepool Bridge consistently show some of the highest nitrate levels, with GlanCorran reaching a peak of 7.40 mg/L in May 2025.

  • Significant Drops: Llandawke and Broadway Cav Park both show a significant drop to 0 mg/L in August 2025, which corresponds to the "NIL Water" notation.

  • Stable Levels: Several locations, such as Culvet and Newbridge Bridge, show relatively stable nitrate levels over the period, fluctuating within a narrow range.

  • Horsepool Bridge: This location shows a notable peak of 7.20 mg/L in January 2025 before the levels normalize and fluctuate between 4.40 and 5.80 mg/L for the rest of the period.

Generally, moderate levels of nitrate are part of a healthy aquatic ecosystem, but excessively high levels can lead to problems like algae blooms. The ideal concentration can vary depending on the type of water body and its intended use.

The chart, titled 'Phosphate Levels Over Time by Location', shows how the phosphate concentrations have changed from November 2024 to August 2025.

Here's an analysis of the trends:

  • Significant Spikes: Culvet had a notable spike in May 2025, reaching a high of 0.44 mg/L.

  • High Fluctuations: Broadway Cav Park, Horsepool Trib, and Hill Farm Stables show more significant fluctuations in phosphate levels compared to other locations. Broadway Cav Park, for example, dropped to 0.03 mg/L in March 2025 before a sharp increase in May 2025.

  • Lowest Levels: AberCorran consistently shows some of the lowest phosphate levels, staying below 0.15 mg/L throughout the entire period.

  • Final Readings: Like the ammonia data, Llandawke and Broadway Cav Park ended with a reading of 0 mg/L in August 2025, corresponding to the "NIL" notation.

Generally, high phosphate levels in water can contribute to excessive algae growth, which can harm aquatic life. The ideal phosphate concentration is often very low, especially in freshwater systems.
