La Cienega’s springs and wetlands are important hydrologic, ecologic and cultural resources, and provide many beneficial water-related functions. The wetlands discharge groundwater from regional and local aquifers that provide the sole water source for the southern Santa Fe region. We investigate the wetland system by examining the hydrologic interactions manifested in the wetland water balance.

Aquifer test index- December 2016- This index has been compiled from reports by consultants, the U.S. Geological Survey, the Office of the State Engineer, the New Mexico Bureau of Mines and Mineral Resources and other sources. It is highly recommended that users of the Index check the data against the original publications. Interpreted results presented in the index are those provided by the authors of the test reports. Most references are available in the Office of the State Engineer library.

The county water level monitoring program was formally launched in February 2010. Based on data collected since that time, the Office of the State Engineer closed the Sandia Underground Water Basin to new water rights appropriations, though new and replacement domestic wells can still be drilled. The data indicate that some area of the county, particularly the East Mountains, are experiencing significant annual water level declines on the order of two feet per year or greater. The East Mountains and North Albuquerque Acres areas are heavily dependent on domestic wells or water supply. Information on the program and a participation application are available at https://www.bernco.gov/public-works/public-works-services/water-wastewater-stormwater/groundwater-resources/groundwater-projects.

The Environmental Services Division conducts aquifer groundwater monitoring at approximately 130 selected wells within the Albuquerque city limits. Groundwater monitoring activities consist of groundwater sampling collection and measuring hydrologic parameters. The monitoring program provides consistent and representative data aimed at assessing the chemical water quality of Albuquerque's underground aquifer. It determines spatial and temporal trends in water quality. Approximately 170 samples are collected from Environmental Services Division wells an an annual basis. Water table elevations are also measured to track short and long term hydrologic changes. The information gathered through the groundwater monitoring program is used to assess the groundwater resource, project future conditions of, address contamination concerns, and provide the information necessary to protect our underground aquifer. It is available and shared with local, state and federal organizations. This application provides two different ways to explore City of Albuquerque Groundwater Level Measurements. One is a mapping application and the other is a dashboard. Select a tab on the top to switch between the two applications.

Groundwater recharge indicates the existence of renewable groundwater resources and is therefore an important component in sustainability studies. However, recharge is also one of the least understood, largely because it varies in space and time and is difficult to measure directly. For most studies, only a relatively small number of measurements is available, which hampers a comprehensive understanding of processes driving recharge and the validation of hydrogeological model formulations for small- and large-scale applications. We present a new global recharge dataset encompassing >5000 locations. In order to gain insights into recharge processes, we provide a systematic analysis between the dataset and other global-scale datasets, such as climatic or soil-related parameters. Precipitation rates and seasonality in temperature and precipitation were identified as the most important variables in predicting recharge. The high dependency of recharge on climate indicates its sensitivity to climate change. We also show that vegetation and soil structure have an explanatory power for recharge. Since these conditions can be highly variable, recharge estimates based only on climatic parameters may be misleading. The freely available dataset offers diverse possibilities to study recharge processes from a variety of perspectives. By noting the existing gaps in understanding, we hope to encourage the community to initiate new research into recharge processes and subsequently make recharge data available to improve recharge predictions.

The Pliocene to lower Pleistocene Ancha Formation, upper Santa Fe Group, is a relatively coarse deposit found south and west of Santa Fe, northern New Mexico. It extends southward from the downdropped southern Española Basin of the Rio Grande rift onto a weakly faulted structural platform that extends to the Rio Galisteo, a distance of approximately 30 km (19 mi). The Ancha Formation is found as far west as the La Bajada escarpment (also ~30 km distance). The Ancha Formation is texturally variable but predominately a sand to gravelly sand, with clayey-silty, fine-grained sand increasing towards the southwest. Examination of well logs indicates that the lower part of the Ancha Formation is commonly gravelly. Due in part to its relative coarseness, the Ancha Formation forms a locally important shallow aquifer for the Santa Fe area. The characteristics of the formation’s base and its thickness are important to regional groundwater studies and are also useful for other studies involving basin stratigraphy, structure, geophysical interpretations, and basin evolution. The base of the Ancha Formation coincides with a Pliocene erosional surface overlying tilted and faulted beds of the Tesuque Formation (upper Oligocene-upper Miocene), the Espinaso Formation (upper Eocene to lower Oligocene), the Galisteo Formation (Eocene), and, locally, older Mesozoic and Paleozoic units. In order to characterize the thickness and the basal contact of the Ancha Formation, three data sets were evaluated: (1) cuttings and geophysical logs of key exploration drill holes and water wells, including monitoring wells; (2) lower resolution, generalized lithologic logs from water wells; and (3) outcrop exposures of the basal contact. This report presents the latest lithologic, thickness, and hydrologic observations for the Ancha Formation in the Santa Fe embayment in the form of four map plates: (1) Plate 1, elevation contour map of the base of the Ancha Formation; (2) Plate 2, isopach map showing thickness of the Ancha Formation; (3) Plate 3, saturated thickness of the Ancha Formation (2000 to 2005 conditions); and (4) Plate 4, subcrop geologic map showing distribution of strata underlying the Ancha Formation. Supporting data are presented in five tables.

Larger Commercial & Industrial Processes Suitability Map. Ground source heat energy, sometimes called shallow geothermal energy, can be collected from the ground and boosted with heat pumps. This can yield up to four times as much energy as is used to collect it, giving ‘four for the price of one’ in energy terms. Heat energy can be harnessed, or ‘collected’, using different types of collector systems: Closed loop collectors are systems where heat is extracted from the ground (or cooling is gained) by pumping a heat exchange fluid through closed pipes within the ground. The pipes can be installed borehole(s) (vertical closed loop) or laid out horizontally (horizontal closed loop). Open loop ground source heat systems operate by taking heat energy from abstracted groundwater using a heat pump. The volume of groundwater that can be abstracted from a borehole or taken from a spring each day (the ‘yield’) determines the total amount of heat energy available, and therefore the size of heat pump that can be used and the size of building that can be heated. The ground source heating/cooling suitability maps indicate which type of ground source heat collector is most compatible with the geology below your site. All maps should be assessed together, since whilst some areas may be unsuitable for one type of ground source heat collector system (‘ground source heat pumps’ or GSHPs), the heat energy can be successfully harnessed by a different type of system. The maps show that there is a shallow geothermal solution for heating or cooling for every location in Ireland. The suitability maps use a suitability rating ranging from 1 (worst) to 5 (best) for each type of heat collector/cooling system. Suitability maps for open loop (domestic/small commercial), open loop (larger commercial/industrial processes) and vertical closed loop systems are available.

Groundwater Drinking Water Protected Areas (DWPA's) submitted as part of the Water Framework Directive (WFD) 2nd cycle reporting in 2016.  The extent of each protected area was created by NIEA Land & Groundwater team.In order to provide water for people to drink we abstract raw water from reservoirs, rivers and the ground (known as groundwater).  These areas are referred to a Drinking Water Protected Areas (DWPAs) within the Water Framework Directive. Where necessary this raw water is treated to purify it for us to drink. Groundwater DWPA's include areas where water is/ can be abstracted for public or private drinking water supplies, for direct inclusion within food (e.g. cooking or food preparation including processing, preservation or marketing of products or substances intended for human consumption), but not water intended for indirect uses such as spray irrigation.

The Washington State Department of Ecology (Ecology) Water Quality Program undertook the Nitrate Prioritization Project in 2014 (Morgan, 2014) because of growing concerns about groundwater contamination by nitrates, and the inability to display and evaluate nitrate data on a statewide basis. This report originated from the agriculture and water quality talks that took place in 2012. Participating agencies agreed that if data exists, everyone should be able to see it in one central location. Agencies that contributed included the Washington Dept. of Ecology, Washington Dept. of Health, Washington Dept. of Agriculture, U.S. Environmental Protection Agency, U.S. Natural Resource Conservation Service, U.S. Geological Survey, and the Washington Conservation Commission. The Safe Drinking Water Act nitrate limit for delivery of water from public water systems is 10 mg/L. This limit has been exceeded in public water supplies and private wells in various areas of the state going back decades. Not only is contaminated groundwater a public health issue, treatment is also very costly to the public water supply systems and individual households who must deal with contamination on their own. The goals of this project were to: Collect and organize statewide information about nitrate monitoring results, the physical factors that tend toward nitrate contamination, and United States Geological Survey (USGS) risk studies that evaluate the physical factors against monitoring results. Delineate areas where high nitrates in groundwater occur. Prioritize those areas by potential impacts to people and resources. Make the information available to everyone. The inputs for developing candidate Nitrate Priority Areas include: A single database of nitrate sampling results for groundwater compiled from state and federal databases. USGS nitrate risk studies. Surficial geology, soil properties, topography, well locations and depths, agricultural land use, irrigated areas, annual average precipitation, nitrate concentrations, and population. Monitoring data from the USGS and the Washington State Departments of Health and Ecology were collected and summarized. The well locations were mapped using a Geographic Information System (GIS). Clusters of wells where a sample has exceeded 10 mg/L are a strong indicator that groundwater at that location is at high risk of, or currently is contaminated by nitrate. Other indicators include USGS nitrate risk analyses, Natural Resources Conservation Service (NRCS) soil drainage classes and travel time through the soil profile (Ksat), surficial geology, recharge and well depths.Boundaries for candidate Nitrate Priority Areas were developed based on section lines that approximate natural boundaries. These areas will be subject to review and change where appropriate. Once the proposed Nitrate Priority Areas have been reviewed, section line-based boundaries may be replaced by natural boundaries where appropriate. Time series plots were produced for wells with four or more sample results with at least one result over 5 mg/L. This resulted in a distribution of over 1200 graphs across the state. These are accessible through the GIS as a popup from the well location point for those who have a GIS system with this capability, and who request and receive the necessary files. A web-based application would make these graphs widely and easily available. Challenges with databases always include checking for errors, such as the occasional locational or data entry error. Care must be used to understand the limitations of the data and the peculiarities of each data source. These issues are described more in this report. Recommendations include developing a web application to make this information easily accessible by anyone with internet access, and automating the data downloads so they are easily updated. Management of nitrate sources to prevent groundwater contamination should be adjusted for sensitive conditions like excessively draining soils and very hydrologically conductive geologic materials. Nitrate source loading needs to be reduced in impacted areas to prevent groundwater contamination. Results of this study can be used to protect public drinking water supplies by focusing actions on areas within the state that have the highest potential for impacts due to nitrate contamination of groundwater.

The Healy Collaborative Groundwater Monitoring Network is a statewide well measurement network, with wells measured in a variety of ways (i.e. pressure, acoustic, and manual measurements), as well as compiling data from various regional networks. This is an API link to these well locations and associated data.

The Arroyo Hondo ground water study reveals a complex, three-dimensional ground water system with multiple hydrostratigraphic units and aquifers. Distribution of the geologic and hydrostratigraphic units is presented through geologic maps and seven detailed cross sections that depict the distribution of geologic and hydrostratigraphic units, well data, surface water features, water levels, faults, and zones of fracturing and sediment layers in volcanic rocks. Cross sections are constructed both parallel and perpendicular to regional ground water flow and illustrate aquifers in the context of the geologic framework, the Rio Grande and the Rio Hondo, local acequias and other surface water features.

This report presents the results a hydrologic investigation at White Sands National Monument (WHSA) in southern New Mexico. The principle objective of this study is to develop a conceptual model of the shallow groundwater system within the gypsum dune field with the intent to increase our understanding of how it interacts with the larger, regional hydrologic system. The monument, which encompasses approximately 115 square miles, includes a portion of the largest gypsum dune field in the world.

This package contains the supplementary information (SI) of chapter 4 of the dissertation of Frederik T. Weiss with the Dissertation No. ETH 27434 (defended: 24th February, 2021), entitled: "Pesticides in a tropical Costa Rican stream catchment: from monitoring and risk assessment to the identification of possible mitigation options". Generally within this thesis the supplementary information (SI) is divided into three parts (SI A, SI B, SI C). For each chapter, SI A section contains background information/data for the reader with quick and easy access added directly after each main chapter. SI B contains raw data, further processed data for analysis, and figures of processed data presented as Excel files. SI C combines the R scripts with information and commands utilized for the statistical analysis. The abstract of chapter 4 reads as follows: "Finding targeted strategies to mitigate entry of pesticides into surface waters in areas of intense agriculture is challenging. This holds especially true in little studied areas with very distinct topographic characteristics and unconventional field cultivation practices, such as in the tropical Tapezco river catchment in Costa Rica. Within this catchment, areas with steep slopes are used for intense horticultural farming of mainly vegetables. This is exclusively done by a farming practice similar to contour farming, the practice of tilling land with furrows along parallel lines of consistent elevation in order to conserve rainwater and to prevent soil losses by erosion. At the same time, slope-directed paths are implemented to act as drainage system to avoid stagnant water on the fields during heavy rain events, though as well connecting the fields directly with the streams, which enable a fast pesticide transport. Indeed, a significant contamination of streams with pesticides and pesticide transformation products (PPTP) throughout the Tapezco river catchment has been confirmed, leading to considerable toxicological risks to aquatic communities, urgently calling for effective mitigation strategies to reduce PPTP inputs. To identify how PPTP are transported from horticultural areas into streams of the Tapezco river catchment, different PPTP transportation pathways were considered. The first investigated pathway was via handling practices of pesticides by farmers and field workers, where inappropriate handling was proposed to lead to sporadically distributed pesticide inputs unrelated to hydrology. The second studied pathway was surface run-off. Typically, heavy precipitation events are found to be important drivers for the surface-based transport of pesticides into the streams. Thus, such pesticide inputs can be assumed to correlate positively with water levels in the receiving streams. Surface run-off is additionally favored by the slope-directed paths on the fields, which directly connect fields with the streams. Therefore, the influence of prevalent topographical and hydrological variables on PPTP inputs via surface run-offs were studies within this thesis. The third potential investigated input pathway was the leaching of pesticides into the ground from where pesticides can enter streams via exfiltration through river banks. This path would be expected to lead to a constant input that is negatively correlated with water levels. To investigate the role of these pathways in transporting PPTP into the streams, pesticide peaks unrelated to hydrology were identified based on measured environmental concentrations (MEC) of PPTP and compared with water level time series. Survey data about pesticide handling practices were evaluated additionally. Temporal PPTP distributions were investigated during three sampling periods (ΔT1, Δ2a, Δ2b) within 2015 and 2016 and spatial trends were studied at eight sub-catchment (SC) sites. In addition, knowledge on the topography (share of horticultural land, share of forest in the 100 m stream buffer zone, average slopes of the horticultural fields) and hydrology (median water level factors) was considered. These variables were referred to as explanatory variables while 20-, 50- and 80-percentiles of MEC were considered dependent variables. The explanatory and dependent variables were correlated via linear regression modelling for identifying the most important determinants of PPTP transport. There, 20-percentiles represent a scenario with low precipitations, no or low surface run-offs and low PPTP inputs; 50-percentiles a scenario with medium precipitations, resulting in medium surface run-offs and PPTP inputs; and 80-percentiles a scenario with high precipitations, heavy surface run-offs and high PPTP inputs into streams. With a focus on potential mitigation measures achieving the highest effectiveness for reducing risks to aquatic biota, analyses were performed on a sub-set of PPTP that dominated the risks to aquatic organisms, along with three transformation products (TP) to calculate TP/PPTP ratios as a measure of pesticide residence time. The correlation analysis of the PPTP input pathways was again based on eight SC sites. The input of three pesticides were very likely due to inappropriate handling. For five additional pesticides, the input via inappropriate handling seemed probable. Temporal exposure trends were observed by comparing the MEC during the sampling period with reduced precipitation (ΔT1, in 2015) with the MEC detected at periods with normal precipitations (Δ2a, Δ2b, in 2016). In addition, spatial trends were investigated by conducting a cluster analysis with the MEC PPTP data (20-, 50- and 80-percentiles) among the different sites. Particularly the pesticide distributions at SC2 and SC3 were different compared to other sites (SC1, SC4, SC6, SC7 and SC8). However, except for the 20-percentile scenario, the pesticide distribution at SC5 was similar compared to that at SC2 and SC3, forming one sub-cluster. Linear regression models helped to find relationships between two explanatory variables, namely, the share of forest in the buffer zone, and mean slopes of horticultural fields, and the dependent variable, MEC percentiles in streams. For five PPTP, boscalid, diazinon, diuron-desdimethyl, linuron and prometryn + terbutryn the percentile concentrations decreased significantly with increasing share of forest in 100 m river buffer zone considering all scenarios. With regard to the horticultural mean slope, for cyhalothrin and thiamethoxam, the percentile concentrations increased with increasing mean slopes of the horticultural areas for all three scenarios. A high share of forest in the buffer zone worked generally as barrier for input via surface run-off, but not for all PPTP. For the fungicide, carbendazim, increased average slopes did not favor the input into the streams and inputs were low even at sites with horticultural areas with a high mean slope (80 percentile scenario). By analyzing groundwater samples it became apparent that, especially in SC with horticultural fields with low average slopes, a leaching of PPTP into groundwater and further transport into the streams via exfiltration might be possible. Based on this assessment, three avenues for mitigating input of PPTP into the streams could be deduced: to provide training workshops for better handling as well as biobeds for proper disposal; to avoid cultivation of crops in high need insecticides on steep slopes; and to establish forested buffer zones between the fields and the streams."

NOTE: This Bulletin supersedes Open File Report 591 (OFR-591). East-central New Mexico is dependent on groundwater from the High Plains aquifer for agricultural, municipal, industrial, and domestic uses. Ongoing declines of water levels in the High Plains aquifer are well-known and have led residents and decision-makers to speculate on the usable life of the aquifer. This Bulletin presents aquifer lifetime projections for eastcentral New Mexico based on projecting historical water-level trends into the future using over 1,500 wells. Projections for the useful lifetime of the aquifer for agricultural and municipal/domestic-use scenarios are described. Several quantitative measures of the reliability of the results are presented. The results are stark, with projected usable lifetimes in many areas only ten years or less. Much of the region already has insufficient saturated thickness for the operation of large-capacity irrigation wells.

These publications are related to water, water resources, and hydrogeology. The Groundwater Reports series was discontinued and was superseded by the Hydrologic Reports series. Hydrogeologic Sheets are essentially geologic maps of relatively small areas with a hydrogeologic focus and include data on groundwater elevation and chemistry. Of course, a large number of our publications not listed here — like geologic maps, open-file reports, and several of our technical monographs — relate directly or indirectly to water resources as well. We also have two Decision Makers Field Guides that focused on water resource issues that are written for a non-technical audience. See our Aquifer Mapping Program page for the results of more current water-related work.

The Remediation Oversight Section encourages and oversees voluntary efforts to clean up contaminated sites, and administers the Ground and Surface Water Protection Regulations that require responsible parties to clean up contaminated soil and groundwater.

Water levels in the karstic San Andres limestone aquifer of the Roswell Artesian Basin, New Mexico, display significant variations on a variety of time scales. Large seasonal fluctuations in hydraulic head are directly related to the irrigation cycle in the Artesian Basin, lower in summer months and higher in winter when less irrigation occurs. Longer-term variations are the result of both human and climatic factors. Since the inception of irrigated farming more than a century ago, over appropriation of water resources has caused water levels in the artesian aquifer to fall by as much as 230 ft (70 m). The general decline in hydraulic head began to reverse in the mid-1980s due to a variety of conservation measures, combined with a period of elevated rainfall toward the end of the twentieth century.

ISC measures groundwater levels monthly in a network of wells in and surrounding its Pecos Settlement augmentation well field in the Seven Rivers area.

Source Water is the raw, untreated supply of water from surface water or groundwater used for current or future drinking water. Source Water protection reduces the risk of water getting contaminated. It is a very efficient and cost saving way to protect the safety and long-term use of safe drinking water for our communities. Source Water Protection Program works with water systems and communities on source water planning and partners with other state, federal, local entities for special projects that study important source water threats and issues.

The Stygofauna Mundi database is an Access database gathering all the information on groundwater crustacean species distribution contained in 36 chapters of Botosaneanu L. (1986). These chapters were digitised in the framework of the EU FP7 BioFresh project. Botosaneanu L. (1986). Stygofauna Mundi. A faunistic, distributional, and ecological synthesis of the world fauna inhabiting subterranean waters (including the Marine Interstitial). Leiden E.J. BRILL. The Netherlands. 740 pages.

USGS groundwater data, information, data, and maps for Georgia. In particular - Figure 2: Surface-water and ground-water data-collection stations in Georgia. From site: The USGS provides maps, reports, and information to help others meet their needs to manage, develop, and protect America's water, energy, mineral, and land resources. We help find natural resources needed to build tomorrow, and supply scientific understanding needed to help minimize or mitigate the effects of natural hazards and environmental damage caused by human activities. The results of our efforts touch the daily lives of almost every American.

Brackish groundwater (BGW), defined for this assessment as having a dissolved-solids concentration between 1,000 and 10,000 milligrams per liter is an unconventional source of water that may offer a partial solution to current (2016) and future water challenges. In support of the National Water Census, the U.S. Geological Survey has completed a BGW assessment to gain a better understanding of the occurrence and character of BGW resources of the United States as an alternative source of water. Analyses completed as part of this assessment relied on previously collected data from multiple sources, and no new data were collected. One of the most important contributions of this assessment is the creation of a database containing chemical data and aquifer information for the known quantities of BGW in the United States. Data were compiled from single publications to large datasets and from local studies to national assessments, and includes chemical data on the concentrations of dissolved solids, major ions, trace elements, nutrients, radionuclides, and physical properties of the resource (pH, temperature, specific conductance). This dataset represents major-ions data from a compilation of water-quality samples from 33 sources for almost 384,000 groundwater wells across the continental U.S., Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa. The data are published here as an ESRI geodatabase with a point feature class, and associated attribute table, and also as non-proprietary comma-separated value table. Dissolved-solids data include information for assessing the distribution of dissolved-solids concentrations and other chemical constituents that may limit the usability of brackish groundwater. It was not possible to compile all data available for the Nation, and data selected for this investigation were mostly limited to larger datasets that were available in a digital format. As a result, some data on a more local-scale may not be included.

This dataset represents major-ions data from a compilation of water-quality samples from 16 sources for about 124,000 groundwater wells across the continental U.S., Alaska, Hawaii, Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa. The data are published here as an ESRI geodatabase with a point feature class, and associated attribute table, and also as non-proprietary comma-separated value table. Major-ions data include information for assessing the geochemical-water type, saturation indices, and potential for mineral scaling.

From the site: "The Active Groundwater 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 13 months. This network includes all of these wells, regardless of measurement frequency, aquifer monitored, or the monitoring objective. The U.S. Geological Survey has a database/archive of about 850,000 wells across the Nation. Information about these wells is available to the world via NWISWeb (http://waterdata.usgs.gov/nwis/gw). Through various groundwater programs, the USGS actively measures water levels in, or collects data from more than 20,000 of these wells each year. These wells are measured for a variety of disparate purposes, such as statewide monitoring programs, or more local effects like monitoring well drawdown, hydrologic research, aquifer tests, or even earthquake effects on water levels. There also are a variety of networks among these actively measured wells; a National Climate Response Network for wells, Regional Networks like the High Plains Aquifer Monitoring Program that is designed to monitor storage changes in the High Plains Aquifer, state-based networks that are designed to monitor statewide groundwater conditions, and local networks designed to monitor pumping effects."

USGS Real Time Water Data for New Mexico includes streamflow, groundwater, lake and reservoir, precipitation, and water quality data. 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.

WRRI's Statewide Water Assessment is an effort that will complement existing state agency water resource assessments. It will provide new, dynamic (updated frequently), spatially representative assessments of water budgets for the entire state of New Mexico. Projects included in the Statewide Water Assessment bring new technologies that expand existing studies and are applicable statewide. Of particular interest are water budget components for which state agencies require improved information, such as evapotranspiration (ET), crop consumptive use, groundwater recharge, and streamflow.
