Cleaning up our waters, including iconic sites such as chalk streams, is a top Government priority. That is why on 23 October 2024, the Secretary of State announced the launch of an independent commission to fundamentally transform how our water system works.

Fixing the systemic issues in the water system is essential to address the multiple pressures facing chalk streams, namely over abstraction, phosphorous pollution, and physical modifications of habitats. Restoring our chalk streams to better ecological health is part of our overall programme of reforms for the water sector. Alongside this, we are continuing to direct investment to projects that will improve chalk streams. Through the Water Industry National Environment Programme, over 1000 improvement projects are planned within chalk stream catchments between 2024-2029.

Natural England is supporting the Environment Agency’s Test and Itchen Restoration Strategy. The aim of the project is to restore the Test and Itchen to a more functioning chalk stream habitat. This involves projects to improve the river habitat and reconnecting the river with its floodplain. The work undertaken to date has improved the chalk stream habitat, creating a more resilient river for the species which rely on it such as southern damselfly, invertebrates and fish species such as Atlantic salmon.

Fixing the systemic issues in the water system is essential to address the multiple pressures facing chalk streams, namely over abstraction, phosphorous pollution and physical modifications of habitats.

There is significant investment and improvement work taking place within the Test and Itchen catchments. This includes extensive monitoring of environmental indicators on water quality and ecology; regulation of operators within the catchments such as water and agriculture sectors; working with the water industry on reducing reliance on harmful abstractions and ensuring compensation and mitigation while alternative sources are delivered (for example, Havant Thicket reservoir and associated schemes) and tackling diffuse water pollution. Much of this work includes contributions from a wide range of partners including wildlife trusts, rivers trusts, fisheries managers, landowners, water companies and regulators.

The Environment Agency undertakes regular sampling of the biodiversity in the Test and Itchen and publishes the results on the Environment Agency’s Ecology and Fish Data Explorer. This is freely available via the Government’s Open data website: EA Ecology & Fish Data Explorer

I pay tribute to the Friends of the Itchen Estuary for their advocacy on this important issue. The Department for Environment, Food and Rural Affairs ran a consultation on reforms to the Bathing Water Regulations 2013, which closed on 23 December 2024. We are currently analysing the responses and considering how any proposed changes may impact the application and designation process, and we will of course respond fully in due course.

Levels of E. coli and faecal matter in the River Itchen remain disgustingly high. I commend the Friends of the Itchen Estuary group for their work to highlight the issue. Like me, they want designated bathing water status in order to protect the river, so will the Secretary of State update us on when that application process will open again and on what changes we can expect?

The Secretary of State recently met with water company bosses, including Southern Water, to make clear that water firms will be held accountable for their performance for customers and the environment. During the meeting, water bosses signed up to the Government’s initial package of reforms to cut sewage dumping and attract investment to upgrade infrastructure.

The Government also announced a new Water (Special Measures) Bill, which will turn around the performance of water companies, in the King’s Speech. The Bill will strengthen regulation, give the water regulator new powers to ban the payment of bonuses if environmental standards are not met and increase accountability for water executives. These are the first critical steps in enabling a long-term and transformative reset of the entire water sector.

I would also refer the hon. Member to the Written Statement made by the Secretary of State on 18 July: Written statements - Written questions, answers and statements - UK Parliament.

Protecting our rivers and water bodies is a top priority for HM Government. We are taking action to address pollution from a variety of sources to improve water quality.

To tackle pollution to waterbodies from agriculture we have almost doubled the funding available for our Catchment Sensitive Farming programme over the next three years. Our new £30 million budget will expand the programme to cover 100% of farmland. We have also made extra budget available this year to the Environment Agency (EA) for 50 extra inspectors to be recruited in this financial year to visit farms posing a risk of water pollution and ensure action is taken.

The EA is working specifically across Hampshire catchments with farmers and landowners to ensure they are compliant with Environmental Regulations. This includes work via the Agriculture Regulatory Taskforce (ART), funded by Defra, to tackle diffuse pollution. On farm visits, EA officers issue actions for farmers to reduce pollution risk and improve the environment.

Chalk streams are both incredibly rare and a hugely important part of our environmental heritage. To protect the iconic chalk streams of the Test & Itchen, the EA is working with regional water resource planning groups to make sure these habitats are rightly prioritised, while delivering a resilient water supply to this growing area.

To tackle water pollution from sewage discharges, we have recently published our Storm Overflows Discharge Reduction Plan. Our Plan sets new strict targets on water companies to reduce sewage spills and will secure the largest infrastructure programme in water company history - £56 billion capital investment over 25 years.  Water companies are also required under the Environment Act to monitor the water quality impact up and downstream of all their assets. This monitoring data will be used by the EA to assess compliance with permits.

The Environment Agency (EA) monitors groundwater boreholes in the surrounding area of the Alre catchment (where Alresford Salads factory is located), and in the principal River Itchen, for atrazine and its breakdown products. The EA therefore holds monitoring data on atrazine and its concentrations for the River Itchen and groundwater in the Alre catchment, including self-monitoring data provided by Alresford Salads. The data confirms that riverine concentrations of atrazine within the Itchen are consistent with atrazine concentrations detected in groundwater. The data shows a reduction in atrazine concentrations over time, and consistently below the Environmental Quality Standard, Drinking Water Standard and Predicted No Effect Concentration.

Atrazine is a herbicide that no longer has EU approval for use. Its use was restricted in 2006 and completely withdrawn in 2007 in the UK.

The current Water Framework Directive classification for the River Itchen is Good.

The Environment Agency (EA) regulates abstraction from and discharges to rivers by issuing permits and checking that these are being complied with. Permit limits are set to ensure the protection of the environment. The EA regularly reviews permits based on the evidence available and it amends these limits when necessary.

As part of its ongoing programme of restoring sustainable abstraction the EA is reviewing abstraction permits. Since 2007 this work has reduced the amount of water being abstracted from the River Itchen catchment each year by more than 5.35 million cubic metres. The EA is also reviewing discharge permits and has successfully reduced the levels of chemicals such as phosphates entering the river system.
