Produced Water | Session IX - JP Nicot
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 aims to validate the Soil Vulnerability Index (SVI) for identifying Critical Source Areas (CSAs) of pollution in two watersheds in the Chesapeake Bay region. The SVI ranks soil vulnerability based on characteristics like drainage and slope. It was applied to the Tuckahoe Creek Watershed and Greensboro Watershed, which have different soil types. Hydrologic modeling outputs from SWAT were used as a reference to validate the accuracy of the SVI classifications in each watershed. The results suggest the SVI performs differently depending on landscape characteristics, so multiple approaches should be used to identify CSAs to inform conservation practices.

Towards a Near Real-time Agricultural Drought Monitoring and Forecasting
Towards a Near Real-time Agricultural Drought Monitoring and ForecastingNational Institute of Food and Agriculture
This document discusses using machine learning techniques to forecast agricultural drought by incorporating high-resolution soil moisture data. It aims to 1) forecast soil water deficit index (SWDI) up to one week using support vector machines (SVM) improved with dual ensemble Kalman filters, and 2) evaluate satellite-derived soil moisture against in situ observations to assess its use in drought indices. The results show dual EnKF greatly improves SVM predictions of SWDI at different soil layers and SMAP satellite soil moisture captures the dynamics of root-zone soil moisture compared to in situ observations.CV

Session 6.5 modelling the effects of adopting agroforestry on basin scale run...World Agroforestry (ICRAF)
1) The study used the SWAT model to simulate the impacts of land use change on hydrologic services in the Gabayan watershed in the Philippines under three scenarios: current land use (S0), degraded land use (S1), and conservation agriculture with agroforestry (S2).
2) Results showed that S1 increased surface runoff, reduced gradual release of water flows, increased sediment yield 155% and sediment concentration 165% compared to S0.
3) S2 was found to improve hydrologic indicators, increasing gradual release and reducing sediment yield by 20% and sediment concentration in critical sub-basins by 35% compared to S1.Land cover change analysis
This document summarizes land cover change analysis tools and data developed by NOAA to improve conservation and restoration efforts in the Great Lakes region. It describes the Coastal Change Analysis Program, which maps land cover every 5 years. Analysis of C-CAP data from 1985 to 2010 found increases in developed and scrubland areas and decreases in agriculture, forest, and grasslands. The document also outlines a land cover atlas, wetland modeling tool, planned water quality tool, and an open-source nonpoint source pollution model.
Environmental Flows Update, Tony Smith
This document discusses environmental flows in Texas. It provides a historical overview and outlines the paradigm shift that occurred with the passage of Senate Bill 1 in 1997, Senate Bill 2 in 2001, and Senate Bill 3 in 2007. These bills required the Texas Commission on Environmental Quality to adopt rules related to environmental flows and establish standards and procedures. The document then summarizes key aspects of the administrative code related to environmental flows, components of instream and estuarine freshwater inflow regimes, required work plans, funding and priority projects from 2014-2015 and 2016-2017, and implementation requirements regarding permit adjustments.
TMDLs in Wastewater
The document discusses Total Maximum Daily Loads (TMDLs) which are formulated by the Department of Environmental Protection (DEP) and approved by the EPA to address water quality issues caused by nitrogen loads in impaired bodies of water. A TMDL determines the maximum amount of a pollutant a waterbody can receive daily from various point sources like stormwater discharge and nonpoint sources like septic systems. It is broken down into wasteload allocations, load allocations, and a margin of safety. Towns then undertake comprehensive wastewater management planning to evaluate solutions to reduce nitrogen loads based on the allocations in the EPA approved TMDL.
SDP120116f
This document summarizes a study that examined the impacts of climate change on urban stormwater best management practices (BMPs) in the Spokane River watershed. The study used a water quality model to simulate hydrology and water quality over a 10-year historic period and projected conditions for 2050 under climate change scenarios. The results indicated significantly higher streamflows during winter and spring months due to increased precipitation falling as rain rather than snow. Water temperatures and instances of dissolved oxygen levels below standards also increased. This implies that the currently proposed 50% reduction in nonpoint source nutrient loading through BMPs will not be adequate to meet water quality goals under future climate conditions, and that BMPs will need to be designed to handle larger storm
LCRA Lane City Reservoir Project, Karen Bondy
The document summarizes LCRA's plans to expand water supplies in central Texas to meet growing demands through 2070. It discusses developing groundwater resources, building the Lane City Reservoir downstream on the Colorado River, and other projects. The 40,000 acre-foot Lane City Reservoir would capture additional runoff and increase system efficiency, with an annual firm yield of 90,000 acre-feet. It requires various permits and has engineering controls like cutoff walls. LCRA is also building the smaller Prairie Conservation Reservoir to enhance irrigation operations in the Lakeside Division.
Produced Water | Session X - Alleman
This document summarizes water management considerations for hydraulic fracturing operations in the Bakken shale formation in North Dakota. It discusses water use, sourcing, transportation, storage, treatment and disposal of produced water. The average water use per well is 2.1 million gallons, ranging from 1 to 9.5 million gallons, with primary sources being municipal fresh water and Lake Sakakawea. Produced water quality ranges from 30,000 to 250,000 ppm TDS. Approximately 20% of produced water is reused for fracturing while the remaining 80% is disposed via underground injection.

Produced Water | Session VI - Ben Sebree
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.
Removing phosphorus from drainage water the phosphorus removal structure
Full proceedings available at: http://www.extension.org/72839
We constructed a phosphorus (P) removal structure on a poultry farm in Eastern OK; this is a BMP that can remove dissolved P loading in the short term until soil legacy P concentrations decrease below levels of environmental concern. A P removal structure contains P sorbing materials (PSMs) and are placed in a location to intercept runoff or subsurface drainage with high dissolved P concentrations. As high P water flows through the PSMs, dissolved P is sorbed onto the materials by several potential mechanisms, allowing low P water to exit the structure. While they vary in form, P removal structures contain three main elements: 1) use of a filter material that has a high affinity for P, 2) containment of the material, and 3) the ability to remove that material and replace it after it becomes saturated with P and is no longer effective.
PacIOOS WQB Data QC
This document discusses the quality control (QC) challenges of collecting continuous water quality data from PacIOOS water quality buoys. It describes the manual and automated data processing and QC done at different time scales, from twice-daily checks to annual adjustments using software. Some sensors, like the dissolved oxygen sensor, required adjustments to the data over time. Independent data is also used to validate the buoy measurements. Lessons learned from 5 years of monitoring include the need for redundant sensors for QC checks and that some sensors do not work well in shallow, subtropical environments. Routine monitoring provides valuable research data.
SURFACE WATER QUALITY ASSESSMENT USING GIS
This document summarizes a study assessing the surface water quality of Perumbakkam Lake in Kanchipuram district, South India using Geographic Information Systems (GIS). 15 water samples were collected from locations around the lake and analyzed for physicochemical parameters like pH, alkalinity, hardness, chlorides, TDS, fluoride, iron, and ammonia. The results were mapped spatially using GIS to analyze the spatial variation in water quality. Most parameters were within permissible limits except for high TDS levels at some locations, possibly due to industrial and domestic waste discharge. The study aims to help monitor water quality and identify sources of pollution impacting the lake.
Operation of SAWS New Groundwater Desal Plant - Richard Donat
The document discusses the SAWS Brackish Groundwater Desalination Project. It outlines the water supply challenges facing San Antonio that led SAWS to pursue brackish groundwater desalination. The Phase I project involves drilling 12 production wells to draw brackish water from the Lower Wilcox Formation and treating the water through reverse osmosis to produce 12 MGD of drinking water. The document discusses various challenges faced in planning, designing, constructing, and operating the desalination facility.
Study: Water Footprint of Hydraulic Fracturing
A so-called study by an anti-drilling Duke University professor, Avner Vengosh, who says frackers have used 250 billion gallons of precious water from 2005-2014. That's less than 1% of water used in industrial activities--essentially an asterisk in water usage. But Vengosh points out the environmental holocaust that teeny tiny bit of water can still create. It's a bogus study.
Instream Limestone Sand Dosing in the Allegheny Plateau
Scott Alexander with Malcolm Crittenden and Robert Ryder, PA Department of Environmental Protection (DEP), “Instream Limestone Sand Dosing in the Allegheny Plateau”
Attendees will learn of the successful recovery of trout populations in low-buffered,
acidic streams by the use of alkaline treatments. Documented low-cost/long term trout restoration methods such as (ILS) may be useful for other watersheds dealing with stream acidification because several high cost alternatives have been proposed in Pennsylvania which on analysis may deliver far less stream-alkalinity per dollar.

#6 - Comp Plan - Surface Water
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.

#13 - Comp Plan - Trends & Implications -continued
The document discusses various demands on and trends affecting mining, recreation, public lands, flood control, groundwater recharge, and water quality in a watershed district. Mining is expected to use alternative water sources and change pumping rates to reduce impacts. Recreation is increasing but management of lands and water remains limited. Public land uses impact water quality and management challenges may rise. Flood control focuses on maintaining existing profiles but climate change could increase atypical floods. Groundwater recharge may become a larger district focus. Water quality faces threats from development and storms, and portions of watersheds lack needed infrastructure.
#12 - Comp Plan - Trends & Implications
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.
#11 - Comp Plan - Wetland Management
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.
#10 - Comp Plan - Wildlife Management
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 District carries out its business through budgets, staff, land management, provision of services, contracts, cooperation, and collaborative efforts.
#8- Comp Plan - Water Quality
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.
#7 - Comp Plan - Lakes
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.
#2- Comp Plan - Issues input
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.
#4- Comp Plan - Evaporation & Evapotranspiration
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.
#3 - Comp Plan - Climate & Precipitation
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.
#1 - Comp Plan 2010–2020 Intro
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.
#5 - Comp Plan - Groundwater
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.
CLAA component of Crooked Lake Management Plan

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
