River Taf Water testing results-April 26
Based on the data for the River Taf in April 2026, the situation is significantly more extreme than in the smaller tributaries. While the Nitrate levels are lower, the pH levels have reached a critical and potentially dangerous stage. Here is the breakdown of the April 26 results for the three main Taf sites (Llandowror, Whitland Church, and the Water Monitoring Station): 1. Critical pH Readings (The Primary Concern) This is the most alarming part of the Taf data. The pH has

April. Testing results for the River Corran and Mackerel Lake stream
Spring River Health Report (April 2026): Tracking the "Invisible" Surge In April 2026, the monthly monitoring has revealed a significant trend across the catchment. While our rivers appear visually clear and healthy, the chemical data reveals a hidden "nutrient surge" that is affecting the river’s ecology. The Post-January Loading Phase Under current Welsh regulations (CoAPR), the closed period for slurry spreading ended on January 15th. Since then, there have been three mont

River Taf Water Testing results
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

Water testing results for March 26
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

Using Horsetail (Equisetum arvense) as a garden spray.
Often dismissed as a stubborn, invasive weed, Horsetail ( Equisetum arvense ) is actually a "living fossil" that has survived for over 300 million years. For the organic gardener, it is a potent resource—a natural, mineral-rich tonic that acts as both a defensive shield and a growth stimulant. Using horsetail as a garden spray provides a range of benefits that chemical alternatives simply cannot match, primarily due to its unique chemical composition and ancient evolutionary

Weeding the pavements in Laugharne
Please do help us weed the pavements in Laugharne so the County council do not spray. If you can help us please do contact Charles or David. Even if you just weed outside your property it would help.

Garden Composting
Turning Waste into Wealth: The Vital Role of Garden Compost Bins In an era where sustainability is no longer a choice but a necessity, one of the most powerful tools for environmental change is sitting quietly in the corner of many backyards: the compost bin. Often overlooked as just a receptacle for kitchen scraps and garden trimmings, the compost bin is actually a sophisticated biological engine. It transforms organic waste into "black gold," providing a circular solution t

River Corran and Mackerel lake Stream first year report.
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.
