What is Leachate Water Analysis?

Leachate Water Analysis is a process used to assess the safety of groundwater supplies. It measures the levels of contaminants, such as heavy metals and other pollutants, in leachate water. Conducting this analysis helps ensure that drinking water sources are safe for human consumption and protects aquatic ecosystems from potential contamination.

Leachate Water Analysis allows you to:

  • Identify any pollutants or contaminants present in the water supply
  • Monitor changes over time to detect if further pollution is occurring
  • Make informed decisions on how best to manage wastewater disposal
  • Assess the risk of potential health issues caused by exposure to contaminated water

Water Types

Water types are categorised based on their source and regulated by government authorities and the Environment Agency for analysis.

ACS offers all the water testing services you need to cover any specific water type and requirement.

Water types we can test for include:

  • Potable water (drinking water) from tap, borehole/well, or tank
  • Surface water (river, pond, etc.)
  • Leachate (landfill borehole or runoff from an identified source)
  • Eluate (similar to leachate but normally laboratory derived)
  • Seawater
  • Groundwater

If you need a different type of water test, please ask; we can usually accommodate.

Leachate Testing

Leachate testing involves analysing the water to determine its chemical composition. This is undertaken using standard laboratory equipment such as a pH meter, conductivity meter, and other testing equipment. To obtain an accurate result, samples are collected using sterile containers and stored at a precise temperature before they are analysed.

The key tests that can be performed on leachate include:

Chemical analysis

This tests for contaminants like metals, organic compounds, and nutrients that could indicate the presence of leachates.

Microbiological analysis

This test detects microscopic organisms in the sample. These organisms are not visible to the naked eye but can have significant negative impacts on the environment if left uncontrolled.

Electrical analysis

An electrical analysis measures the electrical conductivity in the sample and can help identify any potential leachates.

The Leachate Water Analysis tests compare results to standards. This is done to check for leachate presence and identify the type of contamination it may have.

Our scope of laboratory methods for leachate preparation includes:

  • Leachate preparation (single step L/S 2 test) – BS EN 12457-1

  • pH dependence leaching test (initial acid/base addition) – CEN/TS 14429
  • pH dependence leaching test (continuous pH control) – CEN/TS 14997
  • WAC leachate preparation (two-step L/S 2 plus L/S 8 test) – BS EN 12457-3
  • Up-flow percolation test – CEN/TS 14405
  • Tank test – EA NEN 7375
