Undertaking a Clean Water Survey

You can now actively participant in current scientific research by using quick and simple kits to measure the levels of two widespread pollutants, nitrate and phosphate, in your local freshwater habitats. Help to discover flourishing freshwater habitats, where wildlife still thrives, and uncover the facts about nutrient pollution.

Freshwater habitats, from the biggest lakes to the tiniest trickles, pools and springs, are home to a vast array of plants and animals. It only takes a little pollution to cause the loss of much of this wildlife. Both nitrate and phosphate pollution cause profound changes to plant and animal communities, and in the worst cases, the habitat becomes green. However, the changes can often be subtle. To start with, the water may still look clear, but an increase in the invisible nutrients means that sensitive species are lost and the habitat slowly becomes poorer in wildlife. It is now more important than ever to find the clean water places, those that are free of pollution.

All the information you will need for the survey is sent to you in our Thames Water for Wildlife Leaflet that comes with the water testing kits.
