the Essex ponds are very polluted

This last week I have visited the Nevendon Road Mitigation site and tested the conductivity of the ponds which were created for the release of great crested newts. The lost of two ponds were effectively replaced with 6 new ponds.

This area of Essex is heavily farmed and it is assumed that the nutrient load is very high. The results of the meter readings were very high from all the ponds 0.8 to 1.4 mS the middle pond was the ‘cleanest’ with a reading of 0.6mS.

In contrast my clean water garden pond is around 0.15mS and the tin streaming ponds in Cornwall were 0.08mS (see photos)

It just goes to show what a difference there is in the country with water quality. In Essex will it be possible to create clean water ponds?

It is interesting to note that the great crested newts numbered just over 2000 compared to the London Gateway project which created over 35 new ponds this number is massive. The London Gateway was reported to have moved around 400 great crested newts. Just goes to show how unimportant the great crested newt population was at the London Gateway.
The 41 ponds which were created on adjacent land has now riddled the Essex marshes with holes reminiscent of the german bombs jettisoned during the blitz in world war II.

There was a reported 100,000 smooth newts at the London Gateway yet they stayed in Essex unlike the poor reptiles which are now in Wiltshire.

clean water!
