Standard Practice for Depth Measurement of Surface Water

Standard Practice for Depth Measurement of Surface Water

SIGNIFICANCE AND USE
5.1 This is a general practice intended to give direction in the selection of depth measuring procedures and equipment for use under a wide range of conditions encountered in surface water bodies. Physical conditions at the measuring site, the quality of data required, and the availability of appropriate measuring equipment govern the selection process. A step-by-step procedure for actually obtaining a depth measurement is not discussed. This practice is to be used in conjunction with a practice on positioning techniques and another practice on bathymetric survey procedures to obtain horizontal location and bottom elevations of points on a water body.
SCOPE
1.1 This practice guides the user in selection of procedures commonly used to measure depth in water bodies that are as follows:    
Sections  
Procedure A—Manual Measurement  
6 through 11  
Procedure B—Electronic Sonic-Echo Sounding  
12 through 13  
Procedure C—Electronic Nonacoustic Measurement  
14 through 15
The text specifies depth measuring terminology, describes measurement of depth by manual and electronic equipment, outlines specific uses of electronic sounders, and describes an electronic procedure for depth measurement other than using sonar.  
1.2 The references cited and listed at the end of this practice contain information that may help in the design of a high quality measurement program.  
1.3 The information provided on depth measurement is descriptive in nature and not intended to endorse any particular item of manufactured equipment or procedure.  
1.4 This practice pertains to depth measurement in quiescent or low-velocity flow. For depth measurement related to stream gauging, see Test Method D3858. For depth measurements related to reservoir surveys, see Guide D4581.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 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.

Standard Test Methods for Measurement of Water Levels in Open-Water Bodies

SIGNIFICANCE AND USE
4.1 These test methods are used to determine the gauge height or elevation of a river or other body of water above a given datum.  
4.2 Water level data can serve as an easily recorded parameter, and through use of a stage-discharge relation provide an indirect value of stream discharge, often at a gauging station.  
4.3 These test methods can be used in conjunction with other determinations of biological, physical, or chemical properties of waters.
SCOPE
1.1 These test methods cover equipment and procedures used in obtaining water levels of rivers, lakes, and reservoirs or other water bodies. Three types of equipment are available as follows:    
Test Method A—Nonrecording water-level measurement devices  
Test Method B—Recording water-level measurement devices  
Test Method C—Remote-interrogation water-level measurement devices  
1.2 The procedures detailed in these test methods are widely used by those responsible for investigations of streams, lakes, reservoirs, and estuaries, for example, the U.S. Agricultural Research Service, the U.S. Army Corp of Engineers, and the U.S. Geological Survey.2 The referenced ISO standard also furnishes useful information.  
1.3 It is the responsibility of the user of these test methods to determine the acceptability of a specific device or procedure to meet operational requirements. Compatibility between sensors, recorders, retrieval equipment, and operational systems is necessary, and data requirements and environmental operating conditions must be considered in equipment selection.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 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.  
1.6 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.

ASTM D5540-13(2021)(Practice)
Standard Practice for Flow Control and Temperature Control for On-Line Water Sampling and Analysis

SIGNIFICANCE AND USE
5.1 Sample conditioning systems must be designed to accommodate a wide range of sample source temperatures and pressures. Additionally, efforts must be made to ensure that the resultant sample has not been altered during transport and conditioning and has not suffered excessive transport delay. Studies have shown that sample streams will exhibit minimal deposition of ionic and particulate matter on wetted surfaces at specific flow rates (1-5). 3  
5.1.1 To ensure that the physical and chemical properties of the sample are preserved, this flow rate must be controlled throughout the sampling process, regardless of expected changes of source temperature and pressure, for example, during startup, or changing process operating conditions.  
5.2 The need to use analyzer temperature compensation methods is dependent on the required accuracy of the measurement. Facilities dealing with ultra-pure water will require both closely controlled sample temperature and temperature compensation to ensure accurate measurements. The temperature can be controlled by adding a second or trim cooling stage. The temperature compensation must be based on the specific contaminants in the sample being analyzed. In other facilities in which some variation in water chemistry can be tolerated, the use of either trim cooling or accurate temperature compensation may provide sufficient accuracy of process measurements. This does not negate the highly recommended practice of constant temperature sampling, especially at 25°C, as the most proven method of ensuring repeatable and comparable analytical results.  
5.3 A separate class of analysis exists that does not require or, in fact, cannot use the fully conditioned sample for accurate results. For example, the collection of corrosion product samples requires that the sample remain at near full system pressure, but cooled below the flash temperature, in order to ensure a representative collection of particulates. Only some of the primary conditioni...
SCOPE
1.1 This practice covers the conditioning of a flowing water sample for the precise measurement of various chemical and physical parameters of the water, whether continuous or grab. This practice addresses the conditioning of both high- and low-temperature and pressure sample streams, whether from steam or water.  
1.2 This practice provides procedures for the precise control of sample flow rate to minimize changes of the measured variable(s) due to flow changes.  
1.3 This practice provides procedures for the precise control of sample temperature to minimize changes of the measured variable(s) due to temperature changes.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.5 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.  
1.6 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.

Standard Practice for Preparation of Substitute Ocean Water

SIGNIFICANCE AND USE
4.1 This substitute ocean water may be used for laboratory testing where a reproducible solution simulating sea water is required. Examples are for tests on oil contamination, detergency evaluation, and corrosion testing.  
Note 2: The lack of organic matter, suspended matter, and marine life in this solution does not permit unqualified acceptance of test results as representing performance in actual ocean water. Where corrosion is involved, the results obtained from laboratory tests may not approximate those secured under natural testing conditions that differ greatly from those of the laboratory, and especially where effects of velocity, salt atmospheres, or organic constituents are involved. Also the rapid depletion of reacting elements present in low concentrations suggests caution in direct application of results.
SCOPE
1.1 This practice covers the preparation of solutions containing inorganic salts in proportions and concentrations representative of ocean water.2  
Note 1: Since the concentrations of ocean water varies with sampling location, the gross concentration employed herein is an average of many reliable individual analyses. Trace elements, occurring naturally in concentrations below 0.005 mg/L, are not included.  
1.2 This practice provides three stock solutions, each relatively concentrated but stable in storage. For preparation of substitute ocean water, aliquots of the first two stock solutions with added salt are combined in larger volume. An added refinement in adjustment of heavy metal concentration is provided by the addition of a small aliquot of the third stock solution to the previous solution.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 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.

Standard Guide for Planning and Implementing a Water Monitoring Program

SIGNIFICANCE AND USE
4.1 The user of this guide is not assumed to be a technical practitioner in the water field. This guide is an assembly of the components common to all aspects of water monitoring and fulfills a need in the development of a common framework for a better coordinated and more unified approach to monitoring water.  
4.2 Limitations—This guide does not establish a standard procedure to follow in all cases and it does not cover the details necessary to meet a particular monitoring objective.
SCOPE
1.1 Purpose—This guide is generic in its application to surface or ground water, rivers, lakes, or estuaries (quantity and quality). It proposes a series of options that offer direction without recommending a definite course of action and discusses the major elements that are common to all purposes of water monitoring.  
1.2 The elements described are applicable whether the monitoring is only for one location or integrates multiple measurement sites for the purpose of assessing a whole watershed, estuary, or aquifer system.  
1.3 This guide is intended to outline for planners and administrators the components, process, and procedures which should be considered when proposing, planning, or implementing a monitoring program. The guide is not a substitute for obtaining specific technical advice. The reader is not assumed to be a technical practitioner in the water field; however, practitioners will find it a good summary of practice and a handy checklist. Other standard guides have or will be prepared that address the necessary detail.  
1.4 Monitoring Components—A water monitoring program is composed of a set of activities, practices, and procedures designed to collect reliable information of known accuracy and precision concerning a particular water resource in order to achieve a specific goal or purpose. The purposes may range in scope from tracking status and trends on a regional or national basis to gathering data to determine the effects of a specific management practice or pollution incident such as a spill. This guide suggests and discusses the following process and components:  
1.4.1 Establishment of program goals and objectives and recording of decisions in a written plan (see 6.1),  
1.4.2 Developing background data and a conceptual model (see 6.1.12),  
1.4.3 Establishment of data (quality, quantity, type) objectives (see 6.2),  
1.4.4 Design of field measurement and sampling strategies and specification of laboratory analyses and data acceptance criteria (see 6.3),  
1.4.5 Data storage and transfer (see 6.6),  
1.4.6 Implementation of sampling and analysis strategies (see 6.4),  
1.4.7 Data quality assessment (see 6.5),  
1.4.8 Assessment of data (see 6.7),  
1.4.9 Program evaluation (see 6.8), and  
1.4.10 Reporting (see 6.9). See also Fig. X1.1 in Appendix X1 and the condensed list of headings in Appendix X2.  
1.5 Monitoring Purposes—Establishing goals defines the purpose for monitoring. Each purpose has some monitoring design needs specific to itself. There are six major purposes for water monitoring. They are as follows:  
1.5.1 Determining the Status and Trends of Water Conditions—This can require long term, regular monitoring to determine how parameters change over time.  
1.5.2 Detecting Existing and Emerging Problems—Determining if, how, or where a substance may move through an aquatic system, or if water quantities are changing.  
1.5.3 Developing and Implementing Management and Regulatory Programs—Includes baseline and reconnaissance monitoring to characterize existing conditions such as to identify critical areas or hot spots; implementation monitoring to assess whether activities were carried out as planned; and compliance monitoring to determine if specific water quality or water use criteria were met.  
1.5.4 Responding to an Emergency—Performed to provide information in the near term.  
1.5.5 Evaluating the Effectiveness of Water Monitoring Programs—Is the ...

Standard Practice for Laboratory Performance Verification of Hydrodynamic Separators for the Treatment of Stormwater Runoff

SIGNIFICANCE AND USE
4.1 This practice provides criteria for the verification of the silica sediment removal efficiency of hydrodynamic separators.  
4.2 Verification can be used to support certification of the technology within different AHJs provided that:  
4.2.1 HDS units are sized using the resulting performance data to treat the prescribed water quality flow rate or annual mass load requirement at the level of performance desired by the certifying entity.  
4.2.2 Scaling of results to different MTD model sizes is in accordance with this standard.  
4.2.3 The technology is designed consistently with the tested unit such that it operates within the specified limits determined by the verification as well as other restrictions placed by the certification entity.
SCOPE
1.1 This practice covers the criteria for the laboratory verification of Hydrodynamic Separators (HDS) as it relates to the removal of suspended solids in stormwater runoff.  
1.2 HDS manufactured treatment devices are placed as offline or online treatment devices along storm drain pipe lines to remove suspended solids and associated pollutants from stormwater runoff. These devices may be used to target removal of other pollutants which are not covered in this standard. The criteria in this standard specifically relate to the removal of silica particles in controlled laboratory conditions, which is considered an appropriate surrogate for predicting the removal of stormwater solids from actual stormwater runoff.  
1.3 This practice provides guidelines for independent regulatory entities, collectively referred to as Authority Having Jurisdictions (AHJs), to streamline data requirements for the certification of HDS devices within their jurisdiction. For any given AHJ, additional criteria may also apply.  
1.4 Units—The values stated in inch-pound units are to be regarded as standard, except for methods to establish and report sediment concentration and particle size. It is convention to exclusively describe sediment concentration in mg/L and particle size in mm or μm, both of which are SI units. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Reporting of test results in units other than inch-pound units shall not be regarded as non-conformance with this test method.  
1.5 Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan (QAPP), a specific verification protocol, or AHJ. It is advised to review one or all of the above to ensure compliance.  
1.6 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.
Note 1: This practice is also intended to ensure that the data resulting from completion of testing in accordance with the ASTM test methods referenced herein can be utilized to satisfy the requirements of the New Jersey Department of Environmental Protection’s manufactured treatment device (MTD) certification process.  
1.7 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.

ASTM E3373-23(Test Method)
Standard Test Method for Scour of Hydrodynamic Separators and Settling Devices

SIGNIFICANCE AND USE
5.1 This test method provides test results for evaluating the potential for scour of sediment captured within a MTD in online and offline configurations.  
5.2 This test method will determine if an MTD can meet the scour performance requirements prescribed by an associated verification protocol or local AHJ requirements.
SCOPE
1.1 This test method covers the testing of hydrodynamic stormwater separators and underground settling devices as it relates to the measurement of the resuspension and washout (scour) of previously captured sediment.  
1.2 Units tested shall be of a size commonly manufactured and available for purchase. In order to facilitate testing it is permissible to substitute alternate materials for the housing and structural components of the test units if operational components are at full size, with identical dimensions, configurations and materials specified for commercial use. Scale models are not permissible.  
1.3 The test method provides a means of evaluating retention of suspended solids previously captured in with a manufactured treatment device (MTD) that is placed as an offline or online treatment device along storm drain pipe lines. It provides criteria in which to evaluate whether the MTD is appropriate for installation in offline or online conditions.  
1.4 This test method provides the means for evaluating the scour potential for both offline and online conditions.  
1.5 Units—The values stated in inch-pound units are to be regarded as standard, except for methods to establish and report sediment concentration and particle size. It is convention to exclusively describe sediment concentration in mg/L and particle size in mm or μm, both of which are SI units. The SI units given in parentheses are mathematical conversions, which are provided for information purposes only and are not considered standard. Reporting of test results in units other than inch-pound units shall not be regarded as non-conformance with this test method.  
1.6 This test method may be subject to specific requirements set by a Quality Assurance Project Plan, a specific verification protocol, or Authority Having Jurisdiction (AHJ). It is advised to review one or all of the above to ensure compliance  
1.7 Acceptance of test results attained according to this specification may be subject to specific requirements set by a Quality Assurance Project Plan, a specific verification protocol, or Authority Having Jurisdiction (AHJ). It is advised to review one or all of the above to ensure compliance.
