More Resources for Water Quality Data

With thanks to the Water Quality Monitoring Council and other sources, these are additional resources when looking for water-quality data.

USA national resources

Test your water through a state-certified laboratory listed by the United States’ EPA.

The Texas Commission on Environmental Quality provides a list of certified laboratories that analyze drinking water samples.

National Ground-Water Monitoring NetworkA compilation of selected groundwater monitoring wells from Federal, State, and local groundwater monitoring networks across the nation. The NGWMN Data Portal provides access to groundwater data from multiple, dispersed databases, including the Water Quality Portal, in a web-based mapping application. The portal contains current and historical data including water levels, water quality, lithology, and well construction. The NGWMN is transitioning from a pilot phase into full implementation. In the future we will be adding additional data providers to the network.

USGS Groundwater WatchA distributed water database that is locally managed. Surface water, groundwater, and water quality data are compiled from these local, distributed databases into a national information system. The groundwater database contains records from about 850,000 wells that have been compiled during the course of groundwater hydrology studies over the past 100 years. Includes the Active Groundwater Level Network, National Aquifer Composite Hydrographs, Real-time Groundwater Level Network, Below Normal Groundwater Levels, Climate Response Network, Long-Term Groundwater Data, and Active Spring Monitoring Sites.

The USGS’s MODFLOW 6 groundwater modeling software and user guides are available for download. The U.S. Geological Survey is beginning to transition to the MODFLOW 6 model code for the simulation of groundwater systems. The program has been rigorously tested and reviewed, and new capabilities are under development. It is expected that this new version will keep MODFLOW as the simulation code of choice by the groundwater community.

contamination map: hexavalent chromium, aka chromium 6, aka 'that Erin Brockovich chemical'

Chromium-6 contamination mapIt’s “that Erin Brockovich chemical”: The National Toxicology Program has concluded that hexavalent chromium (also called chromium-6) in drinking water shows “clear evidence of carcinogenic activity” in laboratory animals, increasing the risk of gastrointestinal tumors. In September 2010, a draft toxicological review by the U.S. Environmental Protection Agency (EPA) similarly found that hexavalent chromium in tap water is “likely to be carcinogenic to humans.” (from Environmental Working Group)

Sanibel – Captiva Conservation FoundationFlorida’s River, Estuary and Coastal Observing Network (RECON) is a network of water quality sensors deployed throughout the Caloosahatchee River and Estuary to provide real-time water quality data. Established to understand dynamic and changing conditions in the Caloosahatchee partly caused by extreme freshwater releases from Lake Okeechobee and the Caloosahatchee watershed.

Marine Ecology Progress SeriesThe leading journal in its field, MEPS covers all aspects of marine ecology, fundamental and applied. Topics covered include microbiology, botany, zoology, ecosystem research, biological oceanography, ecological aspects of fisheries and aquaculture, pollution, environmental protection, conservation, and resource management. MEPS aims for the highest quality of scientific contributions, quick publication, and a high technical standard of presentation.

Real-time Water Quality App makes the seas a safer place. The free app alerts water users when sewer overflows discharge untreated human sewage into the sea, and when water quality is reduced by pollution at 315 beaches across England and Wales. Warning beach goers in real time via the Safer Seas Service helps subscribers find the beaches that have the best water quality exactly when they want to hit the beach.
