The city of Grants, New Mexico hired a water consultant to study reports claiming the city was responsible for flooding near Mt. Taylor Addition. The consultant's report found the city's sewer plant and golf course were not the cause of the flooding and that water seepage levels were normal. It noted localized drainage problems but found the water quality at the city facility was better than at Mt. Taylor Addition. The report made recommendations to further reduce seepage and monitor wells, but concluded the city was not responsible for the flooding issues reported.

This document discusses changing water levels in the Great Lakes. It begins with an introduction and outline. It then covers historical water levels, including their seasonal and interannual variation. The main drivers of water level changes are described as the hydrologic cycle of precipitation, evaporation, runoff and flows between lakes. Projections are discussed for both seasonal and decadal timescales. The conclusions discuss challenges around quantifying data value, using models to replace observations, uncertainty quantification and the ability of projections to offer insights rather than firm predictions.
This document discusses how recycling produced water from oil and gas production can help address Texas' growing water supply challenges. It notes that Texas' population and water demand are projected to increase substantially by 2060 while supplies are expected to decline. Recycling two-thirds of the roughly 7 billion barrels of produced water generated annually could meet 3.3% of the state's current water demand and 26% of the projected shortage in 2020, providing an unexpected solution to the state's water crisis through beneficial reuse of this resource.
Laura Fields-Sommers conducted a study assessing the effects of riverbank inducement on groundwater quality in a shallow aquifer in southeastern Wisconsin. She found that 1) cation exchange capacity in wells near the river was depleted, likely due to mixing of river water and groundwater, 2) river water was influenced by wastewater treatment plant effluent as shown through isotopic signatures, and 3) bacterial sequencing revealed genetic markers from human waste at some sampling sites, indicating sewage contamination of the river and groundwater.

Groundwater levels are declining in Chittagong, Bangladesh due to increasing population, urbanization and groundwater extraction. A study analyzed groundwater level data from 2009-2013 in 35 wells across Chittagong. It found that the average groundwater level rose from 43.83m in 2009 to 56.74m in 2013, with declines of 0.122-7.922 m/year in individual wells. A spatial map showed variation in groundwater levels across the city. The study recommends regular monitoring, limiting extraction during dry periods, and using alternative pumps where over-abstracted to manage groundwater sustainably.
This document provides an analysis of the Platte River watershed located in Grant County, Wisconsin. It describes the watershed characteristics including land use, soils, precipitation trends, and stream geomorphology. Two sediment models are developed using factors like slope, soils, land use, and distance to streams to identify areas of high, medium, and low sediment runoff potential. The models are then compared to phosphorus export coefficients from another model called PRESTO to evaluate similarities between areas identified as high or low risk. The analysis finds the second sediment model more accurately identifies a small portion of the watershed as high risk, while the models show similarities for areas identified as low risk.
The document summarizes a study analyzing the adoption of green stormwater infrastructure (GSI) in Tucson, Arizona over the last decade. The key findings are:
1) On average, Tucson sub-watersheds have a GSI adoption rate of 4.7% of treated acreage and 5.8% of treated parcels, indicating room for further implementation.
2) The watersheds with the highest GSI treatment tend to be smaller and closer to urban areas, likely due to higher resident interest and more advocacy.
3) Certain watersheds have met or are approaching a goal of 10-25% GSI adoption, which modeling suggests could significantly reduce stormwater flooding and pollution.

Nearly 80% of the district's water comes from groundwater aquifers that are at normal levels for the season. The remaining 20% comes from regional surface supplies that are also in good shape. Conservation efforts by customers will still be important to manage supply.
Investigating Flooding Pattern Using Hydrologic Engineering Center-River Anal...Niraj Lamichhane
This study analyzed ice jams and flooding in the Grand River watershed in northern Ohio using the HEC-RAS hydraulic model. The objectives were to understand how ice jams contribute to flooding and create flood maps of different return periods. Field data and aerial imagery were used to develop the HEC-RAS model. The model showed that a 500-year flood would inundate homes, bridges and parks. Historical data analysis found that ice jams were most common during neutral ENSO phases. Increased winter temperatures may exacerbate ice jam flooding by accelerating snow and ice melt. The results can help identify at-risk areas and improve flood warning systems.
WATER RESOURCE SUSTAINABILITY OF THE PALOUSE REGION: A SYSTEMS APPROACHRamesh Dhungel
This thesis examines the sustainability of water resources in the Palouse Region located on the border of Idaho and Washington. The region relies on two confined groundwater aquifers, the upper Wanapum and lower Grande Ronde, which show declining water levels. The author develops system dynamics models to simulate population growth, water demand, hydrological processes, and economic factors. The simple model lumps the aquifers together, while the hydraulically separated model divides them based on geology. Water balance calculations estimate recharge rates. Regression analysis determines the price elasticity of water demand. The models project the lifespan of the aquifers under different recharge and demand scenarios. Assuming potential surface water use and a water management strategy,

This webinar provides an in-depth introduction to the 2020 Texas Water Conservation Scorecard. The only effort of its kind in Texas, the Scorecard offers an extraordinarily detailed analysis of water conservation efforts at over 350 Texas water utilities. Jennifer Walker, Deputy Director of the Texas Coast and Water Program at the National Wildlife Federation leads the webinar, along with Ken Kramer, Water Resources Chair at the Lone Star Chapter of the Sierra, and Meghan Bock, Senior Business Analyst at AIQUEOUS.
An initiative of the Texas Living Waters Project, the Scorecard evaluates each utility on a range of criteria including compliance with conservation planning and reporting requirements, its record on water loss and meeting targets for water use reduction, outdoor watering limits, and rate-based incentives for efficient use of water.
Taken in conjunction with the 2016 report, the 2020 Scorecard reveals many utilities are not taking serious actions to advance water conservation.
For more information on the Scorecard’s methodology, results, and recommendations, take a look at the Scorecard website at texaswaterconservationscorecard.org. The interactive site allows users to quickly identify individual utilities’ scores and analysis.

The document summarizes Austin's Water Forward plan to ensure reliable water supply for the growing population. It discusses Austin's current water sources, the historic drought, and recommends a hybrid portfolio approach. This includes maximizing conservation, local sources, and reliability through strategies like aquifer storage/recovery, brackish desalination, reuse expansion, and indirect potable reuse. The plan estimates costs and yields through 2040 and outlines next steps like developing codes/incentives and starting an aquifer storage pilot.
This document summarizes the requirements for developing a water conservation plan in Texas. Municipalities serving 3,300 connections or more, with financial obligations over $500k to the Texas Water Development Board, or with surface water rights from the Texas Commission on Environmental Quality must submit a plan. Plans must be revised every five years and include goals for reducing total, residential, and water loss gallons per capita per day. Details on leak detection programs, non-promotional water rates, conservation best practices, and annual reporting are required. Resources from the Texas Water Development Board like online reporting tools and training are available to help utilities develop effective water conservation plans.
The document discusses new and updated best practices for water conservation planning. It highlights the importance of developing five-year conservation plans and customizing practices to the specific needs and patterns of individual communities. Communities are encouraged to analyze customer water usage data to prioritize effective best management practices such as assistance programs for economically disadvantaged customers, outdoor watering schedules, enforcement of irrigation standards, and custom conservation rebates for industrial and commercial users. Developing a plan that thoroughly discusses strategy, selected practices, and evaluation can receive gold star recognition.
The modification of an existing product or the formulation of a new product to fill a newly identified market niche or customer need are both examples of product development. This study generally developed and conducted the formulation of aramang baked products enriched with malunggay conducted by the researchers. Specifically, it answered the acceptability level in terms of taste, texture, flavor, odor, and color also the overall acceptability of enriched aramang baked products. The study used the frequency distribution for evaluators to determine the acceptability of enriched aramang baked products enriched with malunggay. As per sensory evaluation conducted by the researchers, it was proven that aramang baked products enriched with malunggay was acceptable in terms of Odor, Taste, Flavor, Color, and Texture. Based on the results of sensory evaluation of enriched aramang baked products proven that three (3) treatments were all highly acceptable in terms of variable Odor, Taste, Flavor, Color and Textures conducted by the researchers.

Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

Hurricane Ike occurred in September 2008.
Preparations included having tiered staffing assignments. Response included legislation requiring generators at all water production facilities.
Drought of record stressed our water distribution and productions system. Beginning of focused asset management program.
May 27, 2015 event produced nearly 11 inches of rain and caused flash flooding. Began building flood wall and raising electronics as facilities near bayous.
April 18, 2016 almost 17 inches of rain caused additional flash flooding. Repairs from 2015 were not completed.
May 28, 2016 looking for an ark!
