As it flows, runoff collects and transports soil, pet waste, salt, pesticides, fertilizer, oil and grease, litter and other pollutants. This water drains directly into nearby creeks, streams and rivers, without receiving treatment at sewage plants. Polluted stormwater contaminates local Watershed Tip waterways.

  • Sewage Sludge Program Description
    TEXAS POLLUTANT DISCHARGE ELIMINATION SYSTEM CHAPTER 5 SEWAGE SLUDGE MANAGEMENT PROGRAM DESCRIPTION A. INTRODUCTION Sewage sludge (including domestic septage) use and disposal is regulated in Texas in accordance with the requirements of Title 30 Texas Administrative Code (TAC) Chapter 312. The rules were promulgated under the Texas Water Code, Chapter 5.103 and the Texas Solid Waste Disposal Act (the Act), Texas Health and Safety Code, §§361.011 and 361.024. Title 30 TAC Chapter 312 contain requirements for the use and disposal of sewage sludge which are equivalent to 40 Code Federal Regulations (CFR) Part 503 standards. The 30 TAC Chapter 312 regulations contain requirements equivalent to 40 CFR Parts 122, 123, 501 and 503. Sewage sludge use and disposal requirements will be incorporated into TPDES municipal and industrial facilities as described in Chapter 3. Sludge only permits (facilities that do not discharge to waters of the U.S.) are required to obtain permits from the TNRCC. Sludge only permits include, but are not limited to, any person who changes the quality of a sewage sludge which is ultimately regulated under 30 TAC Chapter 312 and Part 503 (e.g., sewage sludge blenders, stabilization, heat treatment, and digestion), surface disposal site owners/operators, and sewage sludge incinerator owners/operators and domestic septage processing. B. SLUDGE AND TRANSPORTER REVIEW TEAM The Sludge and Transporter Review Team located in the Wastewater Permits Section of the Water Quality Division is responsible for the administrative and technical processing of sewage sludge/domestic septage beneficial use registrations and sewage sludge only permits for facilities treating domestic sewage (primarily facilities as defined in 40 CFR §122.44).

  • Progressive and Regressive Soil Evolution Phases in the Anthropocene
    Progressive and regressive soil evolution phases in the Anthropocene Manon Bajard, Jérôme Poulenard, Pierre Sabatier, Anne-Lise Develle, Charline Giguet- Covex, Jeremy Jacob, Christian Crouzet, Fernand David, Cécile Pignol, Fabien Arnaud Highlights • Lake sediment archives are used to reconstruct past soil evolution. • Erosion is quantified and the sediment geochemistry is compared to current soils. • We observed phases of greater erosion rates than soil formation rates. • These negative soil balance phases are defined as regressive pedogenesis phases. • During the Middle Ages, the erosion of increasingly deep horizons rejuvenated pedogenesis. Abstract Soils have a substantial role in the environment because they provide several ecosystem services such as food supply or carbon storage. Agricultural practices can modify soil properties and soil evolution processes, hence threatening these services. These modifications are poorly studied, and the resilience/adaptation times of soils to disruptions are unknown. Here, we study the evolution of pedogenetic processes and soil evolution phases (progressive or regressive) in response to human-induced erosion from a 4000-year lake sediment sequence (Lake La Thuile, French Alps). Erosion in this small lake catchment in the montane area is quantified from the terrigenous sediments that were trapped in the lake and compared to the soil formation rate. To access this quantification, soil processes evolution are deciphered from soil and sediment geochemistry comparison. Over the last 4000 years, first impacts on soils are recorded at approximately 1600 yr cal. BP, with the erosion of surface horizons exceeding 10 t·km− 2·yr− 1. Increasingly deep horizons were eroded with erosion accentuation during the Higher Middle Ages (1400–850 yr cal.

  • Systems Approach to Management of Water Resources—Toward Performance Based Water Resources Engineering
    water Article Systems Approach to Management of Water Resources—Toward Performance Based Water Resources Engineering Slobodan P. Simonovic Department of Civil and Environmental Engineering, The University of Western Ontario, London, ON N6A 5B9, Canada; [email protected]; Tel.: +1-519-661-4075 Received: 29 March 2020; Accepted: 20 April 2020; Published: 24 April 2020 Abstract: Global change, that results from population growth, global warming and land use change (especially rapid urbanization), is directly affecting the complexity of water resources management problems and the uncertainty to which they are exposed. Both, the complexity and the uncertainty, are the result of dynamic interactions between multiple system elements within three major systems: (i) the physical environment; (ii) the social environment; and (iii) the constructed infrastructure environment including pipes, roads, bridges, buildings, and other components. Recent trends in dealing with complex water resources systems include consideration of the whole region being affected, explicit incorporation of all costs and benefits, development of a large number of alternative solutions, and the active (early) involvement of all stakeholders in the decision-making. Systems approaches based on simulation, optimization, and multi-objective analyses, in deterministic, stochastic and fuzzy forms, have demonstrated in the last half of last century, a great success in supporting effective water resources management. This paper explores the future opportunities that will utilize advancements in systems theory that might transform management of water resources on a broader scale. The paper presents performance-based water resources engineering as a methodological framework to extend the role of the systems approach in improved sustainable water resources management under changing conditions (with special consideration given to rapid climate destabilization).

  • Descriptions of Common Sedimentary Environments
    Descriptions of Common Sedimentary Environments River systems: . Alluvial Fan: a pile of sediment at the base of mountains shaped like a fan. When a stream comes out of the mountains onto the flat plain, it drops its sediment load. The sediment ranges from fine to very coarse angular sediment, including boulders. Alluvial fans are often built by flash floods. River Channel: where the river flows. The channel moves sideways over time. Typical sediments include sand, gravel and cobbles. Particles are typically rounded and sorted. The sediment shows signs of current, such as ripple marks. Flood Plain: where the river overflows periodically. When the river overflows, its velocity decreases rapidly. This means that the coarsest sediment (usually sand) is deposited next to the river, and the finer sediment (silt and clay) is deposited in thin layers farther from the river. Delta: where a stream enters a standing body of water (ocean, bay or lake). As the velocity of the river drops, it dumps its sediment. Over time, the deposits build further and further into the standing body of water. Deltas are complex environments with channels of coarser sediment, floodplain areas of finer sediment, and swamps with very fine sediment and organic deposits (coal) Lake: fresh or alkaline water. Lakes tend to be quiet water environments (except very large lakes like the Great Lakes, which have shorelines much like ocean beaches). Alkaline lakes that seasonally dry up leave evaporite deposits. Most lakes leave clay and silt deposits. Beach, barrier bar: near-shore or shoreline deposits. Beaches are active water environments, and so tend to have coarser sediment (sand, gravel and cobbles).

The process of soil freezing was simulated based on the theory of the energy and mass conservation equations and the equation of mechanical equilibrium. The accuracy of the model was verified by comparison with the experimental results of soil freezing. One-side freezing of a saturated 10-cm-high soil column in an open system with different parameters was simulated, and the effects of the initial void ratio, hydraulic conductivity, and thermal conductivity of soil particles on soil frost heave, freezing depth, and ice lenses distribution during soil freezing were explored. During the freezing process, water migrates from the warm end to the frozen fringe under the actions of the temperature gradient and pore pressure.
