STORage and RETrieval
Began in DOI in 1964
1 Million (plus) Sites
200 Million (plus) Observations
At a conservative $10.00 per obs. (field plus lab
work), data are worth $2 billion!!!

STORET Background
Why STORET? Under the Clean Water Act, states are
responsible for developing and enforcing water quality standards on all lands within their boundary.
Approximately 80% of states used legacy STORET.
Twenty-one states already have data in new STORET as of 3/05/2002.
States with Data in STORET National Data Warehouse as of 03/05/2002
VirginIslands
Why STORET?
Robust, full-featured, well-supported database
NPS runs its copy of STORET; EPA runs the National Data Warehouse
Public can access data at: http://www.epa.gov/storet
Why STORET?
Fully compliant with ITFM and NWQMC metadata recommendations
NPS-77 states that the NPS should provide water quality monitoring data to STORET
NPS has made a significant investment in old STORET with 2.5 million observations at 17,477 stations for 191 parks

Terms Of ReferenceNational Water-Quality Monitoring Council
Approved by the Advisory Committee on Water Information February 18, 1998 Revisions approved by Council August 24, 2000.
Purpose, scope, applicability, and functionsPurpose -- The overall purpose of the National Council is to champion and support water-quality
information aspects of natural-resources management and environmental protection. The National Council has a broad mandate that encompasses water quality monitoring and assessment that includes considerations of water quality in relation to water quantity. The purpose of the National Council is to coordinate and provide guidance and technical support for the voluntary implementation of the recommendations presented in the Strategy for Improving Water-Quality Monitoring in the United States (the strategy) by government agencies and the private sector. The intent of the strategy, presented in the final report of the ITFM, is to stimulate the monitoring improvements needed to achieve comparable and scientifically defensible information on interpretations and evaluations of water-quality conditions.
