Confirmed: The Lake Water Quality is Excellent!

We’ve recently received the latest Certificate of Analysis for The Lake from Mercian Science, and we’re thrilled to share the results. As part of our commitment to safety, we regularly test the water. These new results, based on samples taken on October 6, 2025, show fantastic water quality.

Several areas were tested, giving us a great snapshot of The Lake’s condition.

The Key Takeaway: “Excellent” Bacteriological Levels

The most important news is the exceptional bacteriological quality. To put these numbers in perspective, we’ve compared them to the UK’s official bathing water quality standards.

Here’s a simple breakdown of what they tested for and what they found:

  • E. coli: A result of 0 MPN/1ml. This is the best possible result. For comparison, water can still be classified as “Excellent” with E. coli levels as high as 500 cfu/100ml. A zero reading is truly outstanding.
  • Intestinal Enterococci: A result of 0 cfu/ml. Just like with E. coli, this is a perfect score. The “Excellent” standard allows for up to 200 cfu/100ml, which shows just how clean our water is.

What About Algae and pH?

The lab also checked for other important factors:

  • Total Blue Green Algae: The level was <20 /100mls at both sites. This means the level was below the lab’s minimum detection limit. To put this in context, this result is exceptionally low and signals no sign of an algae bloom.
  • pH: The water’s pH was measured at 8.0 (at 25°C) for both samples. This is an ideal reading. The pH scale runs from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral.
    • To give you some real-world examples, black coffee is acidic, with a pH of around 5.0. Fizzy water is even more acidic, with a pH between 3 and 5, due to the carbonic acid that makes it bubbly.
    • Our lake’s pH of 8.0 is slightly alkaline, which is typical and healthy for a natural lake, falling perfectly within the ideal range of 6.5 to 8.5.

We’re very pleased with this report and look forward to seeing everyone enjoy the clean, safe water at The Lake.

This report is based on Certificate of Analysis Job No: 25-15017, with samples taken on 06/10/2025 and tested on 07/10/2025.
