March results showed readings for Ammonia at all locations. Not critical but an indication that agricultural run off is occurring- not surprising given the rain we have had. Nitrate levels were up slightly on Feb 26 but down on Nov 25. There was a high reading for Phosphate at Llandowror, but again not critical. Most tests show raised levels apart from St Clears, although there was some eddying going on at that location. Dissolved Oxygen was good. PH is a slight concern two r

March saw a slight increase in Nitrate, PH and EC levels. This could be a result of the heavy rains we have had recently causing some agricultural run off. The PH levels are below danger level for aquatic life, but need to be monitored. Any further rise would need investigating, although they would have to remain elevated for many months to cause irreversible damage. Dissolved Oxygen levels are good- ideal for maintaining aquatic life in the river system. Ammonia was only pre

Results of today's water collection and testing on the River Taf. Ammonia was up, phosphate slightly down and nitrate quite a bit down. The river was running pretty fast although using the water clarity meter it was clear.

February 26 Water test results. Most of the results showed reduced levels from January 26 and ammonia was pretty absent. There was a phosphate spike at Horsepool bridge which will need monitoring.

Laugharne Citizen Science started testing the River Corran and Mackerel Lake stream in Nov 2024. The first year results have been analysed and a report produced which you can download via the link below. No major issues but the report covers this in some details. Thank you to all who took part and supported the group to enable us to do this important work . We are carrying on with the Corran and Mackerel lake stream and have just started testing the River Taf and the estuary.

Below are the results of our 2nd test of the River Taf. Now included are dissolved Oxygen, PH and EC.

We started monthly testing of the River Taf today. Anyone who want to help with water collection please let us know.

Charts below show a rolling 12 months results and also the comparison of Nov 24 to Nov 25. Before we collected water there has been 2 weeks of heavy rain , and the high nitrate could be due to the amount of slurry spread on fields before the closed period in mid-October.

Here are the twelve months results. As David said thanks to all the collectors and testers. We are planning to start the estuary and the River Taf soon- if you can volunteer, particularly with sample water collection (pairs of two required) please contact David or myself.

Septembers' water test results for the Corran and Mackerel Lake stream. No water at near Llandawke on the stream. You will see Ammmonia...

If your interested please do sign up here. It is the weekend 19-22nd September .

Please note there was no water on Mackerel Lake stream at llandawke and Broadway caravan park. Thanks as always to the volunteers who helped with collection and testing the samples. As we expand to testing the estuary and the River Taf more volunteers would be welcome. Please contact us if you would like to help.

The results were fairly similiar to last month and showed nothing of concern other than the regualr ammonia reading at Horsepool bridge....

River Corran and Mackerel Lake Stream (The Laques). Below are the results of the water testing the group have been carrying out once a month since Nov 2024. So far the results suggest the river water is of reasonable quality, but we are only half way through the initial 12 months of testing. We are looking to start testing the Taf and Laugharne estuary in the next few months, so if you want to be involved please do join us. The annual membership fee is only £10 a year, we hav
