Water quality

Here are the OPAL water quality results for the pond (proper name is Serpentine Lake) in Alexandra Park

water survey results for Alexandra Park pond

We found various worm-like animals (1 point) water slater (1 point)  and water shrimp (5 points) giving a total of 7 points. Also water fleas, water spiders and water mites but you don’t get any points for them!

The map below shows pond health score results for the Manchester area (where data has been gathered). Red = Pond health score 0-5: This lake or pond needs to be improved. Yellow = Pond health score 6-30: This lake or pond is quite healthy. Green = Pond health score 31 or more: This lake or pond is very healthy. You can see the yellow dot for Alexandra Park pond.

The pond had very poor water clarity. Clear water means more sunlight is getting through – which is important for the survival of many plants and animals. As the water is very murky, some plants and animals may not be able to live there.

Air quality

Just uploaded the data for the OPAL air quality survey, where we looked for lichens and tar spots on the leaves of sycamore trees as indicators of the level of ammonia and nitrogen oxides and sulphur dioxide pollution.

various lichens

The results for Alexandra Park (see below) show the air quality is not that great! But could be worse..

The results of the air quality survey in Alexandra Park 30/7/11

See below how it compares with the surrounding area – seems quite typical, and not as polluted as Leeds appears to be! Red is poor, yellow is not good (our result), green is good or improving, and blue is very good. You can view more details on the OPAL pollution score map.
