Our team of nationally recognised scientists advises a wide range of clients including the Environment Agency and other regulators, water and power companies, government bodies and local authorities.

Water pollution services

Field scientists collecting water samples for water pollution monitoring

We provide services for monitoring both point source and diffuse pollution to help comply with the targets of the Water Framework Directive and Bathing Water Directives.

Our scientists are recognised experts in their diverse and specialist fields offering a professional, client focused service. Our water pollution services include:

  • Rapid call-out service in the event of pollution incidents.
  • High-resolution aerial surveys
  • Diffuse pollution tracing and mitigation
  • Baseline and wet weather diffuse pollution surveys
  • Use of UKAS accredited laboratories for water sample analysis.
  • Pollution from outfall
  • Pollution discharging from a pipe into a small stream
  • Diffuse pollution entering a stream from a pipe

Water pollution experience

APEM is highly experienced in the study and restoration of waters afflicted by Britain’s industrial legacy.

Our water pollution experience includes:

  • Salford Quays and the Manchester Ship Canal are internationally recognised as being among the most prestigious restored waterbodies thanks to the use of oxygen injection and aeration schemes. The £4 million scheme to clean the heavily polluted waters of the upper Ship Canal involved an intensive 20-year period of research and continues to inform many other areas of work.

  • Rapid response call-out in the event of pollution incidents. It is essential to assess the extent of the problem and whether interventions such as aeration, hydrogen peroxide or fish evacuation can alleviate the situation and prevent unnecessary fish deaths. We also offer an independent evaluation on the scale and extent of pollution for use by the prosecution or defence in subsequent court cases.Dead fish in stream
  • Operating a purpose-built litter boat regularly on the River Irwell in Manchester, between Salford Quays and Manchester Cathedral. In 2015, 36,000 litres of litter were collected with the most common problems being plastic bottles, food wrappers and natural debris.

  • Intensive sampling at wastewater treatment works consisting of taking hourly samples from each effluent over three days. Data were provided on product use and breakdown during the treatment process.
  • Long-term monitoring of wastewater discharges following flood damage to assess immediate impacts and recovery over time.
  • In collaboration with the Environment Agency we developed a standardised methodology for the identification and classification of diffuse pollution sources entering Britain’s watercourses. Over 25,000 potential sources were mapped and graded according to their severity in both rural and urban settings.
  • Surveyed the entire River Worfe catchment to identify sources of aquatic pollution, along with other compliance issues related to the Water Framework Directive.
