Water Quality Portal

The Water Quality Portal (WQP) is a cooperative service sponsored by the United States Geological Survey (USGS), the Environmental Protection Agency (EPA) and the National Water Quality Monitoring Council (NWQMC) that integrates publicly available water quality data from the USGS National Water Information System (NWIS) the EPA STOrage and RETrieval (STORET) Data Warehouse, and the USDA ARS Sustaining The Earth’s Watersheds - Agricultural Research Database System (STEWARDS) . It serves water quality data collected by over 400 state, federal, tribal, and local agencies in the United States. As of July 2015, over 265 million results from over 2.2 million monitoring locations are currently accessible through the portal. The portal reports samples and results collected from each location since the beginning of the databases.

水质门户（WQP）是由美国地质调查局（USGS）、环境保护署（EPA）及国家水质监测委员会（NWQMC）共同赞助的一项协作服务，该服务整合了来自美国地质调查局国家水信息系统（NWIS）、环境保护署的存储和检索（STORET）数据仓库以及美国农业部ARS维持地球流域——农业研究数据库系统（STEWARDS）的公开水质数据。该门户提供美国超过400个州、联邦、部落和地方机构收集的水质数据。截至2015年7月，通过该门户可访问超过2.2百万个监测点的26.5亿条记录。该门户报告了自数据库建立以来每个监测点收集的样本和结果。
