BS 8550:2010 Guide for the auditing of water quality sampling

BS 8550 is a key standard for those involved in testing water and making it safe for use.

Why test water?

The sampling and analysis of drinking water supplies is one of the key elements in the protection of public health. Environmental sampling from rivers and other surface waters, sampling of discharges such as treated sewage effluents and trade discharges and sampling of water used for non-potable purposes can also have a significant impact on public health, occupational hygiene and asset durability.

One of the major sources of error in gathering water quality monitoring data can be the sampling process. Poor sampling practices create problems for those interpreting results and can lead to costly and incorrect decisions. Failure to manage factors such as Cryptosporidium levels in drinking water, pneumonia caused by Legionella and heating system corrosion are examples of where failures of quality control/assurance in the sampling process can lead to expensive and potentially life-threatening consequences.

What is BS 8550?

BS 8550 provides an audit protocol to monitor conformity with declared, or assumed, practices in all areas of water quality sampling. Specifically, the standard provides guidance on the systematic assessment of sampling practices and procedures in the field, and assessing conformity with those given in the organization’s sampling manual. It is applicable to the audit of sampling activities from the development of a sampling manual through to the delivery of samples to the laboratory.

BS 8550 applies to the auditing of sampling practices relevant to the management of water stored in containers, such as temporary supply tanks and bottled supplies.

What areas can I use BS 8550 for?

BS 8550 will serve practitioners across the whole range of water quality monitoring areas, for example:
• Wastewaters including discharges to water bodies
• Environmental monitoring
• Potable water supply
• Potable water distribution and use within buildings
• Commercial and industrial uses of water
• Power generation
• Meteorological monitoring.

Who should use BS 8550?

• Water industry (including the environment agency)
• Environmental health officers
• Health and Safety Executive (HSE) specialists
• Water management companies
• Facilities management companies
• Consulting engineers
• Geotechnical engineers
• Hydrogeological consultants
• University departments involved in field studies
• Power generators and other peripheral organizations with a water trade affinity.

Are there any cases that BS 8550 does not apply to?

BS 8550 does not apply for the auditing (or calibration and maintenance) of on-site test equipment or kits.

The following sampling occasions are excluded from both the field and desk-audit procedures set out in this standard:

a) Chemical and microbiological incidents, which are investigated by agencies such as the emergency services, e.g. where an immediate risk to the health of the sampling practitioner/operative is evident

b) Radiochemical sampling of water quality, other than that specified as a routine requirement under the UK Water Supply (Water Quality) Regulations, i.e. radiochemical incidents which are investigated by agencies such as the emergency services.
