1.1This practice provides a methodology for assessing rainwater quality.
1.1.1This practice identifies a set of research and reporting requirements that will permit the intended user to assess the rainwater quality of a catchment area of a particular site.
1.1.2This practice characterizes rainwater quality in general and identifies site conditions that may affect rainwater quality. Where site conditions affecting rainwater exist, additional assessment techniques may be required.
1.1.3Objectives guiding the development of this practice are (1) to synthesize and put in writing good commercial and customary practice for rainwater quality assessment; (2) to facilitate high quality, standardized water stewardship protocols; and (3) to clarify a standard of due diligence that is practical and reasonable.
1.2This practice does not establish design requirements for rainwater harvesting systems. However, it may provide information in support of decisions relative to design and implementation of rainwater harvesting projects.
1.3This practice does not identify use(s) of rainwater, commercial or otherwise. However, it may provide information in support of decisions relative to evaluation of property conditions and development options.
1.4This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment.
1.4.1Water laws vary among governing jurisdictions. It is the responsibility of the user of this practice to determine regulatory requirements applicable to rainwater quality assessment and potential use(s).
1.5The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.6This 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.
1.7This 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.
