The prescription of pharmaceuticals is the most commonly used healthcare intervention and indisputably has an important role to play in human health. However, pharmaceuticals can have negative effects on the environment and living organisms. Firstly, pharmaceutical use significantly contributes to the healthcare sector’s carbon emissions. Secondly, pharmaceutical residues from human excretions and improper disposal of unused medicines can enter the water environment through wastewater and endanger aquatic life.

This report is a quick scoping review (QSR) of peer reviewed and grey literature to provide an evidence-based comparison of different low emission slurry spreading (LESS) approaches in terms of farming practice, ammonia and nitrous oxide emissions and risk of water pollution from slurry spreading to inform farmer-focused guidance on LESS.

The overall aim of the project was to review the effectiveness of standard mitigation measures to maintain the hydrological conditions within peat soils and wetland habitats. The findings of this work will assist the Scottish Environment Protection Agency (SEPA) to provide knowledge and guidance to developers in relation to appropriate construction techniques and enhance practice around avoidance, impact minimisation, habitat creation and restoration.

In 2018/19, Scottish Water’s treatment processes generated c.29,000 tDS²) of Water Treatment Residuals (WTR). WTR, also termed drinking water treatment sludges or bioresource, are produced due to the addition of chemical coagulants to water.

This study carried out by researchers at Glasgow Caledonian University (GCU), with the James Hutton Institute and the Environmental Research Institute (University of the Highlands and Islands) delivered the first national assessment of the emerging area of concern around pharmaceutical pollution of Scotland’s water environment, with an innovative Scottish partnership (One Health Breakthrough Partnership) using results to promote practical actions to reduce this globally recognised public health and environmental issue.

The Scottish Government’s ambition to decarbonise its electricity generation means that run-of-river hydroelectric power schemes are now a feature of many Scottish catchments. The essential requirements of these schemes (adequate hydraulic head and flow) mean that their locations often coincide with important freshwater habitat. A scheme can have various effects on the quality and extent of this habitat, in and downstream of the depleted reach (between the intake and tailrace), and upstream of the impoundment.

This policy brief provides an overview of the types of barriers which inhibit effective engagement with private sewerage users and makes recommendations for overcoming these challenges. The policy brief draws on grey and peer reviewed literature to highlight the key challenges faced by public agencies in engaging householders and communities with their private sewage systems (PSS), and through existing case studies details the types of tools available to support engagement.

Wetlands can be defined as areas of marsh, fen, or peatland with permanent or temporary water (brackish or freshwater). They cover an estimated 2 million hectares of Scotland’s land area from uplands to the coastline and are important for sequestering carbon, providing habitat, storing water, and maintaining biodiversity.

The Metropolitan Glasgow Strategic Drainage Partnership (MGSDP) is a non-statutory partnership between public bodies involved in managing surface water, water quality, flood risk, investment planning and economic delivery, with a vision to ‘Sustainably Drain Glasgow’. The MGSDP began following severe flooding in July 2002 in the East End of Glasgow.

Pathways of diffuse phosphorus and nitrogen pollution from agriculture to the water environment is complex and, sometimes, poorly understood. This report provides a review of the current state of knowledge of several plausible pathways: i) surface runoff and soil erosion, exacerbated by soil compaction and structural degradation ii) role of tramlines, iii) leaching through drain-flow and iv) hotspots that contribute greater than average pollutant loads due to the combined effect of land management intensity and soil properties.
