Water quality chemical testing March 21st 2026.

 On the afternoon of Saturday 21st of March 2026 four Citizen Scientists carried out tests on water from the brook using a pro JBL Pro Aquatest pond kit. We took water samples from the Southbrook section, the section to the west of London Road and a sample from the West Road area. Water samples were tested for pH, nitrates and phosphates.

The test for pH came out as just on the alkaline side of neutral at about pH 7. as expected.

All three samples gave very low readings for nitrate and phosphate being right at the bottom end of the scale.

The conclusion is that at least at this time of the year in March the water quality is really very good with the readings for nitrate and phosphate in particular being significantly lower than those found in the main River Stort.
