Following last month’s chemical spillage into Walsall’s canal network, a section of towpaths and the canal through Pleck remains closed. Walsall Council continues to work closely with the Environment Agency, the Canal & River Trust, with the UK Health Security Agency (UKHSA) and other partners.

Aeration of the canal has been successful. Sediment sampling continues whilst a full remediation plan is being developed. Once that plan is finalised, we will look at next steps and timelines for the reopening of that section of the canal.

Two drop-in sessions for local businesses and residents have been held over the last fortnight where council officers have been joined by colleagues from the Canal & River Trust.

Local, regional and national agencies are working together to minimise the potential risk to health following the spillage. Our priority continues to be the safety of our residents and canal users.

When did the spill happen?

A toxic chemical spillage was discovered in Pleck, Walsall, on Monday 12 August 2024.

In order to avoid potential health risks to the public and to their pets, the canal and towpath were closed from Monday 12 August - initially along a 12-mile stretch, but later reduced to just over half a mile.

How serious is the spill?

The chemical spillage was classified as a major incident, with a multi-agency response by the West Midlands Local Resilience Forum. On Friday 16 August 2024, the major incident was stood down and management of the incident officially moved into a recovery phase.

What chemicals were released into the canal from the spillage?

The spill involved diluted sodium and zinc cyanide and a mixture of low-hazard chemicals.

Are sodium and zinc cyanide harmful to health?

Sodium cyanide and zinc cyanide can be harmful to health, and they cause similar symptoms. You would need to have direct contact with sodium and zinc cyanide for it to potentially cause adverse health effects.

What is the current situation?

Laboratory testing of the canal water conducted by the Environment Agency allowed us to reduce the restricted length of the canal to just over half a mile. Temporary dams were installed at each end of the restricted red zone of the canal, but with water testing showing that levels of pollution had reduced to within public health limits, these were removed on 28 August 2024.

Which areas are affected?

A section of the canal through Pleck remains closed (see map).

How will I know it’s the restricted zone?

The area is cordoned off with clear signage.

What action is being taken?

Thorough testing of the water along the canal has taken place. Levels of cyanide have fallen and are now within public health guidelines. Attention has now turned to the full recovery of the canal, including the impact on wildlife.

Whilst the canal towpath is likely to reopen in the near future, the canal through the impacted stretch will remain closed to navigation until the likely contamination of silt in the bottom of the canal is addressed.

Where did the spill come from?

The source of the spillage from Anochrome Ltd has been stopped. The Environment Agency is leading an urgent investigation into how this pollution incident occurred.

Will the company concerned be prosecuted?

The Environment Agency is carrying out an urgent investigation into the incident and it would be inappropriate to comment further on that live investigation.

Is there a fundraising campaign to help the canal’s recovery?

The Canal & River Trust launched a crowdfunding campaign to help raise some of the funds required. As a charity, they will also be seeking to recover, via the Environment Agency’s investigation and action, the much-needed funds that have gone into responding to the initial emergency and the ongoing recovery of the canal.

What should I do if I feel unwell?

Anyone who has been exposed (direct physical contact with canal water) along the affected stretch of the canal and is feeling unwell should seek health advice via 111 or 999 in an emergency.

What are the symptoms of sodium and zinc cyanide exposure?

If you have direct contact with enough sodium and zinc cyanide you could get headache, nausea, dizziness, nervousness, confusion, changes in heart rate and drowsiness. There may be a delay in the onset of symptoms following contact with the skin. But the sodium cyanide that went into the Walsall Canal was diluted by the canal water, so you are very unlikely to experience symptoms.

What should I do if I fall in or come into contact with the canal water within the cordon?

This section of the towpath is closed and there is no access to the public. You should wash yourself with lots of water and wash your clothes. If you have been splashed with the canal water, it is extremely unlikely you will have symptoms. If you have been swimming or fallen in the water, it is still unlikely that you will become ill. If you have been in direct contact with the canal water or have accidentally swallowed the canal water and have symptoms or are concerned, please phone your GP for advice or contact 111.

I walked along the canal just before the cordons went up. Am I safe?

You do not need to worry if you walked along the canal.

My pet has fallen in the water within the cordon. Are they safe?

This section of the towpath is closed and there is no access to the public. It is unlikely that there is cause for concern due to the dilution of the sodium cyanide in the canal. However, if you are worried, or if your pet is acting out of character, please contact your vet for advice. We would strongly recommend that you do not let your pet enter the water while testing is carried out.

What about fishing?

People are being reminded not to remove and eat fish from canals and it is, in any event, illegal to do so except where required under the Wildlife & Countryside Act. We would strongly recommend that you do not consume anything that you have caught in the canal.

What is the impact on wildlife?

The spillage has been contained to a relatively small area. There have been significant numbers of fish killed, but the impact on the wider ecology is not yet known. Other wildlife in the area may have been affected.

The aquatic ecosystem/food chain may have been devastated or lost for the section the pollution has passed through, from the smallest invertebrates right up to the otter that has a territory through that section. Without natural balance, invasives and algae will quickly take over: the impacts could take years to fully recover.
