Can citizen scientists clean up UK's troubled water?

Volunteers test rivers for chemicals

Resources are being cut by government agencies

Citizen Science aims to improve Waterways

Adam Smith

The Great UK WaterBlitz was organised by Earthwatch Europe and involved thousands of volunteers testing rivers and lakes in 90 different locations.

The charity will analyze the results and send them to the Environment Agency (EA), a government agency responsible for waste management and conservation, and managing water contamination, in an effort to improve the quality of the water.

The condition of Britain's rivers and waterways is a scandal. Privatised water companies are widely criticized for pumping raw sewerage into rivers and oceans.

In a recent report, the National Audit Office (an independent parliamentary institution) said that water infrastructure would require an estimated investment of 47 billion pounds ($62.5 million) over the next five year to repair infrastructure and clean rivers and seas.

"Citizen science can be incredibly powerful in this area." Woods stated that it is a catalyst for meaningful environmental changes - ordinary citizens coming together to create something special in their thousands.

Earthwatch Europe also said that it would use the results from the mass tests to hold water companies accountable for failing to keep waterways clean.

Earthwatch Europe's last testing blitz, conducted in September, revealed a significant amount of antidepressants and agricultural contaminants, as well traces of stimulants such as nicotine and caffeine. The EA began monitoring these substances based on their findings.

DIGNATING Infrastructure

Late last year, lawmakers accused companies of prioritizing dividends and bonuses for management over investments, causing critical infrastructure to degrade.

In October, Britain’s regulator ordered that water companies refund millions of pounds in customer fees for failing to comply with environmental regulations. Now, water company executives can also be charged with criminal offenses if they violate environmental regulations.

Water UK, the company that represents these companies, stated in October that although performance wasn't what it should have been, improvements had been made.

Waterways that are dirty can be harmful to wildlife, ecosystems, human health, and other activities like farming and fisheries.

Woods said that "more polluted waters require more treatment and we will not know what contaminants to remove if we do not monitor what goes into our rivers."

She added that Britain's drinking-water is among the most safe in the world. If we continue to pollute our freshwater systems this might not be the case.

Earthwatch Europe, a charity for the environment, and The Rivers Trust report that significant cuts in the EA has made it more difficult to monitor statutory compliance.

The National Audit Office reported that funding for EA enforcement activities fell by 80 percent, from 117 millions pounds in 2010 down to 23 million pounds by 2020.

The EA stated that it would intensify efforts to hold companies accountable. It tested 4,536 sites in the past year, and is aiming for 10,000 inspections in this year.

"LOVE WHERE YOUR LIVE"

This blitz is a continuation of the work that Keri and Annette Lloyd already do as non-profits Friends of Bilbrook, in South Staffordshire, central England.

They test the water in their local rivers every month for ammonia and other pollutants. The information is then sent to Severn Trent, a water provider, and open data platforms like FreshWater Watch run by Earthwatch Europe.

The residents would like to see stronger relationships between the authorities and the residents. They also said that the EA had not sampled the water in Bilbrook since 2022.

Keri Lloyd said, "We (use) the old motto of 'love your home'", explaining that they felt the collected data was not being used properly. "We want to value it."

The EA stated that there were multiple sampling points near Bilbrook. The site is monitored every five years, with a re-sampling scheduled for 2027.

It said, "We are not able to monitor all our sampling points each year."

Michelle Walker, the technical director at The Rivers Trust said that citizen science was a valuable resource, particularly as government agencies are cutting budgets.

She said that the government no longer collects much data (national) and there are many holes in national data sets.

The trust works with other organisations to create national standards for citizen testing. These include methods for monitoring water, fish populations and soil.

The EA stated that "we encourage an open approach to the data collection and are collaborating with citizen scientists across the country... but this cannot replace all the other reasons why we monitor."

Walker stated that the billions of dollars set aside to monitor combined sewer overflows - pipes that discharge raw sewage in the environment when heavy rain falls - could be used to fund citizen research.

She added that a citizen science program would cost only a fraction of the money the EA spends on monitoring, and the amount the water industry will spend to do the same.

"You can start engaging people about rivers and they will become advocates for their own river." They start local habitat improvement projects and form groups called Friends of the River. "It will pay for itself many times over."
