Baseline Water Quality Data and Water Body Location and Classification

"If there is magic on this planet, it is contained in water." - Loren Eiseley

These inventories include water quality use classifications based upon the Clean Water Act and several basic water quality parameters for "key" water bodies as determined on the basis of size, uniqueness, and threats. Parameters may include alkalinity, pH, conductivity, dissolved oxygen, rapid bio-assessment baseline (EPA/state protocols, involving fish and macro invertebrates), temperature, and flow. Other constituents, as determined on a case-by-case basis, may include toxic elements, clarity/turbidity, nitrate/nitrogen, phosphate/phosphorous, chlorophyll, sulfates, and bacteria.

In addition to the above inventories, the Pacific Island Network funded development of a water quality database for the network.

Status
Horizon reports have been completed for Kalaupapa NHP, Haleakala NP, Kaloko-Honokohau NHP, Puuhonua o Honaunau NHP, Puukohola Heiau NHS and Hawaii Volcanoes NP. Horizon reports are in progress for American Memorial Park, War in the Pacific NHP, and the National Park of American Samoa. Summaries of water quality and water body location and classification can also be found in the PACN monitoring plan and the appended water quality report (see links below) and data available from the Water Resources Inventory.

Making baseline water quality data and analysis reports available for every park with significant natural resources is a cooperative effort of the NPS Water Resources Division (WRD), Environmental Protection Agency, US Geological Survey, and various State, Territorial, and local agencies. The Pacific Island Network water quality database and the associated report were generated by the US Geological Survey Pacific Islands Water Science Center.
