Office of Water - TCEQ - PowerPoint Presentation from the Panhandle Groundwater Conservation Districts Inaugural Texas Panhandle Water Conservation Symposium
This document summarizes Jean-Philippe Nicot's presentation on the source and fate of hydraulic fracturing water in Texas. It shows that hydraulic fracturing water use in Texas increased from 36,000 acre-feet in 2008 to 81,500 acre-feet in 2011, but still represents a small portion of total water use in the state. The source of fracturing water varies by region, with some areas relying more on groundwater or brackish water. Produced water rates decline over time but vary significantly between wells.
This document summarizes characteristics of coalbed methane produced water in Alabama. It notes that over 1.7 billion barrels of water have been produced from nearly 5,000 active coalbed methane wells in Alabama. The water is typically brackish and high in sodium and chloride. While in-stream disposal is most common, there is potential to beneficially use the water for aquaculture, irrigation, drilling, or municipal supply with additional treatment.
This document discusses water quality issues in Ireland and solutions to address them. National water quality monitoring data shows 47% of rivers and 62% of estuaries are in unsatisfactory condition. The two most widespread problems are excess nutrients (nitrogen and phosphorus), with phosphorus and sediment issues impacting 60% of waters needing measures. Maps have been created to identify critical source areas for phosphorus and nitrogen losses from agriculture to target remediation efforts. Measures proposed include riparian buffers, wetlands, and nutrient management plans to reduce nitrogen and phosphorus at their sources and intercept transport pathways.

Water–Demand Management in the Kingdom of Saudi Arabia for Enhancement Enviro...IOSR Journals
This document discusses water demand management strategies in Saudi Arabia. Saudi Arabia faces acute water shortages due to its arid climate and lack of permanent water sources. While water is a renewable resource, availability is extremely low relative to demand, which is increasing rapidly due to population growth and rising living standards. The majority of water is currently used for agricultural irrigation. The document suggests implementing conservation measures, improving water use efficiency, and using technologies like GIS to better manage water infrastructure and demand. The objective is to safeguard this critical resource for future generations through environmental enhancement and sustainable management.
Groundwater can become contaminated through human activities like industrial chemical spills, improper waste disposal, and excessive use of fertilizers and pesticides. Once contaminants enter an aquifer, they can pollute groundwater and cause health issues. Pumping wells can exacerbate the problem by changing groundwater flow directions and spreading pollutants. Various groups need to take actions to prevent contamination, including proper management of industrial waste, reducing agricultural chemical use, and proper household chemical disposal. Remediation methods aim to remove pollution from groundwater, either by extracting and treating water above ground or treating it within the aquifer. Conservation of groundwater resources requires effort from all.
The Gaussian plume model is a simple mathematical model used to predict pollution dispersion from point sources like power plants. It assumes pollutant spread is from molecular diffusion and concentrations follow a double Gaussian distribution based on meteorological conditions. The model calculates concentrations using emission rates, wind speed/direction, stack parameters, and dispersion coefficients that account for atmospheric stability and turbulence. It is one of the most widely used air quality models.

Assessment and surveillance of drinking water qualityjyotinayak44
The WHO published guidelines for drinking water quality to ensure the safety of drinking water supplies. The guidelines relate to acceptability, microbiological, chemical, and radiological aspects of water quality. Key water quality parameters discussed in the document include turbidity, color, pH, chloride, calcium, ammonia, iron, sodium, and bacterial indicators like coliforms and E. coli. Guidelines are provided for acceptable levels of various chemical and radiological constituents in drinking water. Continuous monitoring of water quality is needed to assess safety and protect public health.
The document discusses biochemical oxygen demand (BOD), which measures the amount of oxygen used by microorganisms to break down organic waste in water. When organic waste is present, bacteria consume dissolved oxygen to decompose the waste. BOD tests how much oxygen is absorbed over 5 days at 20°C. A high BOD level indicates more organic waste requiring decomposition, lowering available oxygen for aquatic life. BOD is used to measure water pollution and assess treatment plant performance by comparing raw sewage and treated effluent BOD levels. Proper BOD testing follows steps including sample collection, dilution, seeding with bacteria, initial and final oxygen readings, and calculations to determine BOD in mg/L.
15) groundwater contamination, prevention and remedial techniques as on 27-05...Najam Ul Syed Hassan
This document discusses groundwater contamination and remediation. It introduces groundwater and its importance as a source of drinking water for over 50% of the world's population. It describes how groundwater can become contaminated through human activities like industrial chemical spills and leaks, improper waste disposal, and excessive pesticide and fertilizer use. Both ex-situ and in-situ remediation techniques are discussed for removing contaminants from groundwater, such as pump and treat methods, bioremediation, and air sparging. Specific contaminants like TCE, MTBE, EDC, and gasoline are also summarized along with their typical treatment technologies. The document emphasizes the importance of preventing groundwater contamination to avoid costly
Water pollution occurs when contaminants are released into water sources, degrading water quality for other uses. There are two main types of water pollution: surface water pollution which impacts oceans, rivers and lakes, and groundwater pollution which impacts underground sources. Water pollution can be caused by sewage, industrial waste, marine dumping, and other sources, and has negative effects on the environment, humans, and animals, including toxic water, diseases, and animal deaths. Individual actions like conserving water, proper fertilizer use, and cleanups can help reduce water pollution.
1) Population in the area is projected to increase by 14% by 2020 and housing is projected to increase by 24%. This will result in increased demand for services like water management and recreation.
2) Agricultural and vacant land is expected to decrease by 7,500 acres by 2020, increasing impervious surfaces. This will impact drainage and water quality.
3) Drainage demands are expected to decrease slightly as drainage dependent lands decrease by 642 acres. Maintenance standards for drainage systems will need reevaluation and inspection of critical reaches will be important.
The document discusses various demands on and trends affecting mining, recreation, public lands, flood control, groundwater recharge, and water quality in a watershed district.

The document discusses the relationship between climate change and water resources. It notes that climate change is expected to cause more frequent and severe droughts, reduced water availability, and changes in rainfall patterns. This will negatively impact sectors like food production and increase risks like migration and social conflicts. The UNCCD addresses these issues and aims to mobilize resources and partnerships to support implementation of its objectives to combat desertification and land degradation.
This document outlines the 2014-2018 management plan public input workshop for Crooked Lake. It discusses the status of the current management plan and identifies key issues from the previous plan around invasive species, water clarity, muck, water quality, garbage, water levels, and implications for the future. Data on trends related to these issues is presented. The document concludes that water quality has improved but invasive species remain a challenge and effects of groundwater on water levels needs continued attention. The local water management district outlines ongoing and planned activities to monitor the lake and watershed and develop new management plans and studies.
The Coon Creek Watershed District Board held a hearing to determine if an obstruction in County Ditch 58-6 should be removed. The ditch experiences flooding due to an undersized culvert on Polk Street installed in 1964-1970. Three properties are affected by the flooding. The Board considered inspection reports from 2011 showing flooding, as well as safety and flood damage concerns from the landowners. Engineers recommended replacing the culvert with a longer, larger diameter culvert to reduce flooding and safety issues. Cost estimates were provided and two contractors provided quotes for the work.
1. The National Sports Center in Blaine installed a pervious concrete parking lot section in October 2009 with a grant from CCWD, but it began raveling after 4.5 months.
2. Inspections and testing found the lack of proper curing due to cool fall temperatures caused weakening of the material.
3. The section was reinstalled in August 2010 with involvement from contractors and experts, but more raveling occurred by 2011, requiring repeat inspections and testing to determine the cause and potential solutions.

The document summarizes the 2011 update to the Crooked Lake Comprehensive Management Plan. It outlines the plan's approach of developing strategies to address issues, implementing solutions, monitoring results, and adapting the management plan. Key issues identified include invasive species, water clarity, muck, nonpoint source pollution, and water levels. The document reviews activities from 2009-2012 to address these problems and questions from the public workshop.
The document discusses trends in wetland loss and implications for management. Over 5,137 acres of wetlands have been lost due to drying of the landscape. An additional 8,375 acres, or 52% of wetlands, have lost hydroperiods classified as temporarily flooded or saturated. This drying is causing organic soils to decompose, invasive species to spread, and upland species to colonize wetland areas. The loss of hydrology and wetland functions implies a probable permanent loss of 52% of wetland stock and potential removal from 60-80% of the county due to land subsidence and hydrophobic soils. Managers can expect more delineation challenges and fewer areas meeting jurisdictional wetland definitions going forward.
The document summarizes wildlife and fisheries in a watershed district. It found that habitats and populations were generally in good condition, though endangered, threatened, and special concern species continue to increase, concentrated in the eastern portion. It identifies rare plant communities that require awareness of habitat needs for critical species, and habitat management plans may be developed.
The Coon Creek Watershed District has statutory and regulatory obligations to administer activities affecting water resources, regulate such activities, plan projects, operate and maintain infrastructure, and inform and educate the public. Its mission is to manage groundwater and surface water, maintain hydrologic balance, prevent property damage, protect water quality, and provide for public safety, enjoyment, and resource preservation and enhancement through programs in administration, development regulation, operations and maintenance, planning, information/education, and research/monitoring. The District carries out its business through budgets, staff, land management, provision of services, contracts, cooperation, and collaborative efforts.
This document reviews water quality data from 7 studies in the Coon Creek watershed. It found high levels of suspended solids that exceeded standards once, as well as impaired dissolved oxygen levels in Sand Creek. Trend analyses showed impairments for turbidity, total suspended solids, and phosphorus. The lower portion of the watershed lacks infrastructure needed for water quality improvements.
The document summarizes water quality trends in three lakes - Crooked, Ham, and Netta - located within the Coon Creek Watershed District in Minnesota. It finds that while Crooked Lake has seen significant improvements in water quality from 1983 to 2009, Ham and Netta Lakes have shown no clear trends over the long term for parameters like total phosphorus and chlorophyll-a. Declining water levels pose the biggest threat and risk lower levels that could negatively impact fish and water quality. Water levels are expected to continue dropping with potentially more invasive species issues.
This document summarizes information about surface water in the Coon Creek watershed district. It reviews hydrologic budget data and stream flow variation over 100 years. Analysis of rainfall data from 1985, 1999, and 2009 shows that less than 1 inch of rain did not cause much runoff in 1985, the fate of 1 inch of rain needs to be managed now, and water levels increase substantially with each inch of rain currently. Graphs show increasing water levels over time at three locations. The implications are that the lower watershed remains prone to flooding and shows some independence from the rest of the watershed. Increased erosion and water quality issues are expected in the lower watershed going forward.
This document summarizes discussions from a meeting regarding a 2010-2020 comprehensive water management plan. It identifies state and local agencies in attendance and their initial issues and concerns. These include balancing water quantity and quality, challenges from physical resource limitations, and effectively enforcing regulations. The document also outlines projected rule and permit revisions, program requirements, and a proposed implementation schedule for the comprehensive plan.
This document discusses trends in evapotranspiration and evaporation in the Coon Creek Watershed District over the past decade. It shows that excess precipitation from evapotranspiration and evaporation has decreased based on Thornthwaite and evaporation coefficient models. This decrease in excess precipitation is expected to result in less natural recharge and loss of lakes and wetlands in the watershed district.
The document outlines a plan to update the climate and precipitation chapter of the Coon Creek Watershed District's 2020 Comprehensive Plan. It recommends analyzing updated data sets to bring statistics and trends up to date for the district, reviewing implications of changes in precipitation, and considering increasing volume management requirements to 1.5 inches to address expectations of changes in precipitation volume and support surficial aquifer and water quality management needs.
The 2010-2020 Comprehensive Plan outlines requirements to protect water quality, prevent soil erosion, and reduce pollution over the next decade. It proposes an education program, regulatory inspections, BMP maintenance, and water monitoring. The plan approach involves developing strategies around management, social, and physical factors, then implementing, monitoring, evaluating needs, and using adaptive management over the 10 year period.
This document discusses groundwater storage and flux in the Coon Creek Watershed District. It outlines the surficial geology including lake deposits and river terrace deposits. The generalized geology profiles from west to east and in the upper 120 feet are presented. Implications are discussed such as more available groundwater storage, more infiltration, difficulty maintaining surface water resources, and groundwater resources behaving differently. Expectations for management include increased irrigation demand, and increased recreational/aesthetic use concerns.
The Crooked Lake Comprehensive Management Plan Update 2010 outlines strategies to address key issues impacting Crooked Lake. It reviews water quality, which is currently good due to prevention of turbid conditions. Main issues are Eurasian water milfoil, stormwater pollution, and water levels. The plan develops and implements strategies to continue annual milfoil treatment, encourage buffers and infiltration to reduce pollution, and educate stakeholders on groundwater issues to help manage water levels.
The document is a management plan for Crooked Lake that outlines issues affecting the lake, goals for addressing those issues, and funding from various organizations to implement management activities from 2009-2013. Key points include invasive species as a major issue, with funding for annual chemical treatment and plant surveys. Other issues are water clarity, muck, nonpoint source pollution, and water levels. The plan describes monitoring and best practices to address these problems and protect water quality over time through adaptive management.
The Crooked Lake Area Association drafted a comprehensive management plan to address issues affecting Crooked Lake such as invasive species, muck, nonpoint source pollution, and trash. The plan's goals are to develop a 3D map of the lake substrate, identify strategies to restore lakeshore habitat, increase native plants, reduce impacts of milfoil and curly leaf pondweed, reduce siltation and pollution. Activities include chemical treatments, plant restoration, buffer strips, boat inspections, and increased garbage collection. The estimated costs range from $6,000 to $16,400 annually from 2009-2013. Potential funding sources include membership dues, city contributions, grants, taxes.
