North Herts Council Cabinet Panel for Environment focuses on Water

This Wednesday North Herts Council Cabinet Panel for Environment will be holding a meeting via zoom with a focus on water.

The Panel is comprised of Councillors and all meetings are open to the public to attend. The idea is for it to be a forum where climate/environmental issues can be discussed, and gain the ideas, views, and updates of the public, experts, and councillors.

North Herts Council’s Executive Member for the Environment requested that the topic of the July meeting be Water. The council have requested presentations from the Wildlife Trust on some work they are doing within the district, and the water companies on supply and waste water disposal. Friends of the Rib & Quin have been invited to attend and participate in the public discussion.

You can watch a playback of the streamed meeting from the Council’s YouTube channel below.

FORQ at Braughing Wheelbarrow Race

Pauline, Andy and Toby were at the Braughing Wheelbarrow Race on Saturday to talk to visitors about our chalk streams and show young and old the river flies and other invertebrates that live in them. There was also the opportunity to look at the levels of nutrient pollution in the River Quin with samples taken for both phosphate and nitrate testing.
