Sampling of Wastewater

Standards for wastewater measurements address the standard test methods, guides, and practices for measuring turbidity, flow, and other properties of wastewater, as well as sampling. Given the focus on testing and measurement, standardization of this field of wastewater management has been greatly contributed to by the efforts of ASTM International, previously known as the American Society for Testing and Materials.

For standards addressing content testing, see our dedicated pages for element specific wastewater measurements, and bacteria, biodegradable content, and toxicity wastewater measurements.

ASTM D6538-12(2019)

Standard Guide for Sampling Wastewater With Automatic Samplers

1.1 This guide covers the selection and use of automatic wastewater samplers, including procedures for their use in obtaining representative samples. Automatic wastewater samplers are intended for the unattended collection of samples that are representative of the parameters of interest in the wastewater body. While this guide primarily addresses the sampling of wastewater, the same automatic samplers may be used to sample process streams and natural water bodies. 1.2 The guide does not address general guidelines for planning waste sampling activities (see Guide D4687 ), development of data quality objectives (see Practice D5792 ), the design of monitoring systems and determination of the number of samples to collect (see Guide D6311 ), operational details of any specific type of sampler, in-situ measurement of parameters of interest, data assessment and statistical interpretation of resultant data (see Guide D6233 ), or sampling and field quality assurance (see Guide D5612 ). It also does not address sampling groundwater. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1 Exception The inch-pound units given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Water quality - Sampling - Part 13: Guidance on sampling of sludges

ISO 5667-13:2011 gives guidance on the sampling of sludges from wastewater treatment works, water treatment works and industrial processes. It is applicable to all types of sludge arising from these works and also to sludges of similar characteristics, e.g. septic tank sludges. Guidance is also given on the design of sampling programmes and techniques for the collection of samples.
