The study of water, the promotion of knowledge thereof, and the standardization of terminology methods for:
* Sampling and analysis of water, waterborne materials, and wastes, water- formed deposits and fluvial sediments,
* Surface-water hydraulics and hydrologic measurements,
* The determination of the performance of materials or products used to modify water characteristics, and
* The determination of the corrosivity or deposit forming properties of water.
The term "water" includes, but is not limited to, surface waters (rivers, lakes, artificial impoundments, runoff, etc.), groundwaters and springwaters, wastewaters (mine drainage, landfill leachate, brines, waters resulting from atmospheric precipitation and condensation (with the exception of acid deposition), process waters, potable waters, glacial melt waters, steam, water for subsurface injection and water discharges including waterborne materials and water-formed deposits.
The work of the Committee will be coordinated with other ASTM Committees and other societies and organizations having mutual interests.

Microplastic particles and fibers are now recognized as pervasive in the environment - including wastewater effluent, the ocean water column, sediments, animal tissue and even drinking water. This pervasiveness has led to product bans for small plastics, such as microbeads used in cosmetic products, to larger plastic items that can degrade into microplastics, such as bags and straws. In addition, there are new and planned requirements to monitor microplastics in the environment, wastewater effluent and in drinking water. Implementing monitoring programs requires reliable standardized methods and best practice guidelines. Such methods enable comparison of studies, and the ability to compare quantification among sources. Although the quantification and characterization of microplastics in samples has been occurring for more than a decade, the results are not necessarily reliable or comparable because neither standard field and laboratory methods for collection and identification nor the reference materials necessary for quality assurance yet exist.
