EPA Guidelines: Water and wastewater sampling 2 1.5 Further guidance The principles in this guideline are based on the following standards: • AS/NZS 5667.1: 1998: Water quality—sampling—guidance on the design of sampling programs, sampling techniques and the preservation and handling of samples (Standards Australia 1998a)
2. Records- Keep accurate records of the sampling events and the results. 3. Verify- The results of the compliance monitoring should verify if the SIU is collecting accurate data when they collect their self-monitoring. II. To Fulfill the Sampling Requirements of the NPDES Permit A. Permit required plant sampling: 1.
Analytical parameters determine wastewater sampling protocols. That is, sampling methods, equipment and sample containers must be consistent with the analytes of concern. Parameter-specific procedures are provided in the following sections. All wastewater sampling equipment must be clean and free of contamination that may have occurred
4.2. Sampling Techniques and Equipment 4.2.1. The wastewater sampling techniques and equipment described in Sections 4 through 9 of this document are designed to minimize effects on the chemical and physical integrity of the sample. If the procedures in these sections are followed, a representative sample of the wastewater should be obtained. 4 ...

Select sampling equipment based on the parameters of interest, the specific equipment use and the available equipment. Clean all sampling equipment and obtain clean sample containers using the appropriate protocols specified in SOP 8.1. a. MANUAL SAMPLING: Manual sampling is used for collecting grab samples and/or for immediate in-situ field ...
SAMPLING AND ANALYSIS OF WATERS, WASTEWATERS, SOILS AND WASTES 3 2 SAMPLE COLLECTION Various physical, chemical and biological processes can affect a sample from the time of collection to that of analysis. The use of appropriate sampling equipment, containers and preservation methods to maintain sample integrity will prevent/minimise these effects.
Wastewater sampling is generally performed by one of two methods, grab sampling or composite sampling. Grab sampling is just what it sounds like; all of the test material is collected at one time. As such, a grab sample reflects performance only at the point in time that the sample was collected, and then only if the sample was properly collected.
The sampling technique is determined by the type of water or wastewater to be sampled. This handbook primarily addresses the water and wastewater types shown below and addresses in a limited way, sampling of oceans and estuaries .. 1. Municipal wastewaters 2. Industrial wastewaters 3. Surface waters and sediments 4.
yGrab sample- one sample taken from one point and time yGives an idea of what is happening right then yIntegrated sample- yCombination of grab samples collected at the same time but at different locations. yComposite sample- yMultiple samples taken from one point at multiple times and integrated together for analysis yPulled from a location that provides a composite.
Sampling hand-pump with extension tube – to be used for depth sampling at low flow. Otherwise a sampling beaker (250ml, 500ml or 1000ml) with screw-in extension rods to be used for depth sampling with sufficient flow.

Diurnal profile sampling 2 Sampling Methods and Location Sampling Method There are different ways to take wastewater samples. The simplest way is a “grab sample”, where a sample is collected by filling a sample bottle once. The other common approach is a 24-hour composite sample, where a small quantity of wastewater is collected based
Wastewater Sampling Wastewater Sampling(306)_AF.R3 Effective Date: February 28, 2013 1 General Information. 1.1 Purpose . The purpose of this procedure is to document both general and specific procedures, methods and considerations to be used and observed when collecting wastewater samples for field screening or laboratory analysis.
Frequency of Sampling ⚫ The frequency of sampling depends on the variability of effluent flow rate and on the wastewater characteristics. ⚫ EMB-DENR inspectors must conduct effluent quality monitoring in accordance with their compliance monitoring program for the industry. ⚫ Sampling for significant parameters may be conducted on a monthly
Sampling: The process of removing a sample of a body of water for the purpose of examination of various defined characteristics. 7. Procedure 7.1 Requirements for sampling The sampling SOPs are used to ensure the correct sample collection vessels are prepared and taken on site with the sampler. Also to ensure all

This sampling guide was developed solely for the purposes of the SAMRC wastewater surveillance and research programme. Users are advised that this guide has not been evaluated for purposes beyond the current scope of the SAMRC research programme on wastewater surveillance for SARS-CoV-2. This is a working draft which is updated as required.
General guidance on sampling can be obtained from Pierre Gy’s Sampling Theory and Sampling Practice: Heterogeneity, Sample Correctness and Statistical Process Control (Pitard, 1993) or Sampling for Analytical Purposes (Gy 1999) Liquid wastes should be handled according to methods for sampling waters, while waste soils should be treated
“The objective of sampling is to collect a portion of material small enough in volume to be transported conveniently and yet large enough for analytical purposes while still accurately representing the material being sampled.” 1 Wastewater sampling is generally performed by one of two methods, grab sampling or composite sampling.
