Linlithgow Loch, our town’s beloved landmark and tourist attraction, is facing an environmental crisis. Decades of pollution have led to toxic and odorous algal blooms and a deteriorating ecosystem.
Despite multiple studies, plans and meetings of key stakeholders, progress remains frustratingly slow. It’s time for our community to demand action about the loch.
On March 31st a small, disgruntled group of local residents and councillors left the latest public meeting discussing efforts to reduce pollution in the loch.
Attendees felt that not enough was being done by key agencies involved to move things along. The solutions are varied, complex, costly, take time to have any benefit and multiple cash-strapped agencies are involved.
Summary of situation
Levels of phosphorus and nitrogen exceed recommended levels and feed blue/green algae which bloom and release toxins. Additionally, high chloride (road salt) levels are harmful to aquatic life, further changing the loch’s existing problems. The loch is also vulnerable to “one off” pollution events such as the dramatic but unexplained fish kill earlier this year.
Primary sources in no particular order include:
> Septic tank discharge
> Agricultural runoff of mainly Nitrogen based fertilisers
>Salts spread on the M9 and other roads
> Heavy rain events when Scottish Water’s CSO tank spills sewage into the loch to avoid overloading the local treatment plant unidentified faulty drain connections in Springfield and other areas.
> Run off/drainage in the catchment area from lawn and garden feed products, chemicals in car shampoos.
> Existing pollutants trapped in loch sediment.
So why is action not being taken? Why so slow?
Historic Environment Scotland (HES) are the lead agency as the loch is on their land, but they are not responsible for pollution occurring beyond their boundary of responsibility.
A few initial steps have been taken. The Vennel CSO was upgraded, SEPA funded apportionment study which explained along with previous research the contributing sources and some suggested solutions, farmers are limiting use of expensive fertilisers, drains have been marked to discourage dumping chemicals in street gullies, public meetings, MSP and councillor petitioning and support, etc.
Top Actions that should be achievable.
Awareness
> Improve media coverage.
> Connect and learn from other impacted groups.
> Engage a wider local audience via community events.
> Highlight impact of spraying lawns, washing cars, pouring oils, paints and chemicals down street drains.
> Create a dedicated (non Facebook) website containing all data, contacts, plans, research, meeting dates, etc.
Project Management
> Press for HES to employ a project manager to drive action including measure Bells Burn upstream and downstream of septic tanks.
> Identifying and fixing cross connected pipes in Springfield Estate with help of Scottish Water.
> Planting of trees around the loch and/or reed beds at streams.
> Transport Scotland/BEAR to limit and trap salts and pollutants from M9 gulleys.
> Farmers in catchment area meet with MSPs & ecological experts to discuss funding and any extra action they can take.
> Vennel and Springfield CSO sensors to be upgraded and added to Scottish Water live data website.
These actions are achievable, and we hope the local people, business owners and visitors can all get behind the efforts to clear up Linlithgow Loch.
If you wish to support or raise your concern, you can contact HES, your local MSP, your local councillor, or join the Friends of Linlithgow Loch Facebook page where you will find documents, research studies and past plans.
