Ground-Water Information and Data
The U.S. Geological Survey collects ground-water level data at about 20,000 wells nationwide, 74 in Puerto Rico. The USGS provides long-term, accurate, and unbiased information that meets the needs of many diverse users. The USGS collects ground-water data needed by Federal, State, and local agencies for planning and operating water-resources projects and regulatory programs.
The Puerto Rico ground-water network consists of 74 well sites at which water levels are measured. Twenty four (24) sites are equipped with state of the art data loggers which record the water level at 30 minute intervals and fifty (50) sites are visited once per month for a tape-down water level measurement. The latter consist primarily of wells which do not show any significant water level change as a result of rainfall-recharge events (high transmissive aquifers) or wells which are used as part of the observation network, yet are in active use.

- Active Water-Level Network:
 Quick look:
The Active Ground-Water Level Network contains water levels and well information from more than 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 365 days. This network includes all of these wells, regardless of measurement frequency, aquifer monitored, or the monitoring objective. For more information about this topic, click now.( )

- Climate Response Network:
 Quick look:
The U.S. Geological Survey (USGS) measures more than 20,000 wells each year for a variety of objectives as part of Federal programs and in cooperation with State and local agencies. A small subset of these wells meets the criteria necessary to be included in a "Climate Response Network" of wells designed to illustrate the response of the ground-water system to climate variations nationwide.

- Real-Time Network
 Quick look:
Real-time data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. Data from real-time sites are relayed to USGS offices via satellite, telephone, and/or radio and are available for viewing within minutes of arrival.
