The recent HS2 pollution event at Ruislip rugby club highlighted by the Guardian yesterday is just one of the latest of many pollution incidents we know of in February 2023.
Below a mini geyser at the Ruislip rugby club grounds after HS2 applied anti foam chemicals.
The vast cement works across the Colne valley are generating high levels of Chromium-6. We know this is due to the to the repeated application of Aligh JV to the newly contaminated sites in their Discharge application. The Environment agency are currently considering the 4th variation application.
One of the newly polluted sites to be included in the discharge license is the chalk slag heap on Harefield Moor next to the Hillingdon Outdoor Activity centre lake. The rain water runs off the slag heap and seeps into the ground. HS2 have put in an application to contain collect and transport the water to be cleaned and fed back to river Colne. We are unaware of what happens to the reject water other than it goes into the sewer to Maple Cross that overflows on a regular basis.
Hillingdon Green party are putting in an Emergency motion to the Green Party spring conference to call for a halt to HS2 construction immediately whilst water pollution issues of chromium-6 generation and disposal of plasticisd bentonite slurry escape, are inventigated.
Below we show the Environment Agency public water source protection map for the Ruislip area. Red is the inner source, green is zone 2 and blue is the outer source protection zone. As you can see most of Ruislip should be water source protected. But we are not getting that protection.
