Landscaping at the Water's Edge
LANDSCAPING/GARDENING/ECOLOGY No matter where you live in New Hampshire, the actions you take in your landscape can have far-reaching effects on water quality. Why? Because we are all connected to the water cycle and we all live in a watershed. A watershed is the LANDSCAPING land area that drains into a surface water body such as a lake, river, wetland or coastal estuary. at the Water’sAN ECOLOGICAL APPROACHEdge LANDSCAPING Landscaping at the Water’s Edge is a valuable resource for anyone concerned with the impact of his or her actions on the environment. This book brings together the collective expertise of many UNH Cooperative Extension specialists and educators and an independent landscape designer. Unlike many garden design books that are full of glitz and glamour but sorely lacking in substance, this affordable book addresses important ecological issues and empowers readers by giving an array of workable at the Water’s Edge solutions for real-world situations. ~Robin Sweetser, Concord Monitor columnist, garden writer for Old Farmer’s Almanac, and NH Home Magazine Landscaping at the Water’s Edge provides hands-on tools that teach us about positive change. It’s an excellent resource for the gardener, the professional landscaper, designer, and landscape architect—to learn how to better dovetail our landscapes with those of nature. ~Jon Batson, President, NH Landscape Association Pictured here are the : A major river watersheds in N ECOLOGICAL APPROACH New Hampshire. This guide explains how our landscaping choices impact surface and ground waters and demonstrates how, with simple observation, ecologically based design, and low impact maintenance practices, you can protect, and even improve, the quality of our water resources. -

Geosynthetic Liner Systems for Municipal Solid Waste Landfills: an Inadequate Technology for Protection of Groundwater Quality
Geosynthetic Liner Systems for Municipal Solid Waste Landfills: An Inadequate Technology for Protection of Groundwater Quality G. Fred Lee, PhD, PE and Anne Jones-Lee, PhD G. Fred Lee & Associates El Macero, California Published in: Waste Management & Research 11:354-360 (1993) Waste Management & Research published a paper by Fluet et al. entitled, "A Review of Geosynthetic Liner System Technology" in its March 1992 issue. The geosynthetic liner system technology that they addressed was an engineered containment system for use in lined "dry tomb" landfills in which are placed untreated municipal solid waste (MSW). The "dry tomb" landfilling approach relies on a cover system to in theory keep the wastes dry and a liner system (liner and leachate collection and removal system) to collect and remove leachate. The performance of a "dry tomb" landfill depends on the functioning of the cover and of the liner system for as long as the wastes represent a threat. The Fluet et al. review suggests to the reader that flexible membrane liner systems of the type being constructed today in municipal solid waste landfills will protect groundwater quality from pollution by landfill leachate. Critical examination of the Fluet et al. (1992) review article, however, reveals that they omitted from their discussion some of the most important topics that need to be considered in an evaluation of the efficacy of landfill liner systems in providing truly long-term protection of groundwater quality. Those neglected topics contribute to the assessment of: whether the liner system will prevent groundwater pollution for as long as the wastes represent a threat to groundwater quality. -
Guidance on the Design and Construction of Leak-Resistant Geomembrane Boots and Attachments to Structures
Guidance on the Design and Construction of Leak-Resistant Geomembrane Boots and Attachments to Structures R. Thiel, Vector Engineering, Grass Valley, CA, USA G. DeJarnett, Envirocon, Houston, TX, USA ABSTRACT Experience in reviewing, designing, performing field inspections, and installing of geomembrane boots and connections to structures has revealed a widely diverse practice of standards and approaches. The execution of these details is very much an art in workmanship, and depends a great deal on the experience and understanding of the installer. There is very little guidance in the literature regarding the fine points of specifying and installing these critical details. The typical manufacturers’ details and guidelines are not much more than concepts that have been repeated for two decades. Thus, there is a big difference between what we assume and expect versus what is constructed in terms of leak resistance of geomembrane penetrations and attachments to structures. The goal of this paper is to touch upon some of the detailed and critical aspects that should be addressed when specifying and constructing geomembrane seals around penetrating pipes (referred to as “boots”) and attachments to structures. 1. INTRODUCTION While much attention has been paid in the last 30 years to many other containment issues related to geomembranes (such as chemical compatibility, aging and durability, manufacturing, seaming, subgrade preparation, covering), there is surprisingly little technical discussion related to the design and construction of leak-resistant penetrations and attachments to structures. This subject has largely been relegated to a few simple details, mostly generated by the manufacturers and included in their standard literature. The content of this paper is derived from the authors’ field observations, experience, and deductive reasoning. -

With the geometric population growth in developing nations comes increase in waste generation, these wastes ranging from industrial to agricultural to municipal solid waste calls for measure for its effective management and disposal so as to preserve the ecosystem. An effective measure of containing this large waste generated, is through the use of landfills which are designed and built to protect infiltration of leachates from decomposed waste to the groundwater. -

Garden Ponds Jim Sherman
Garden Ponds Jim Sherman Over the last year, I’ve spent a lot of time pondering. This happens when you’ve got a pond in your garden, and every moment sitting in slack-jawed amazement at all the life thriving in a few gallons of clear amber water is time well spent. My pond is a standard amorphous lumber-yard black-fiberglass prefab, eighteen inches deep in the center with a pair of ten-inch deep shelves molded along what wound up as the east and west ends of the pond, with a capacity of 125 gallons. If I had it to do over again, the financial bullet would have been bitten and a 200 (or more) gallon model purchased; still, even a small pond is one of the most rewarding furnishings a garden can have. A pond is also both a classroom for, and an affirmation of, the organic method of gardening. As the enthusiasm for water gardening grows, countless gardeners who “only wanted to kill the fleas” (or the fire ants, or the aphids) have learned from the fish floating belly-up among the lilies that pesticides kill much farther up the food chain than they realized. Meanwhile, gardeners who refrain from chemical poisons that kill (at least) fish and amphibians in addition to insects fall asleep to the sound of toads in lust, and waken with delight to the sight of gelled ropes of eggs streaming through the water and, later, hundreds of tiny black tadpoles tumbling about in the pond. Toads are the most immediate payoff of having a pond in your organic garden. -
Geomembrane Puncture Potential and Hydraulic Performance in Mining Applications
GEOMEMBRANE PUNCTURE POTENTIAL AND HYDRAULIC PERFORMANCE IN MINING APPLICATIONS Lining systems in mining applications often consist of a geomembrane underlain by either a soil liner or a geosynthetic clay liner (GCL). When under load, geomembranes are vulnerable to damage from large stones both in the compacted soil subgrade and in the overlying drainage layer. Although guidance has been developed for minimizing geomembrane puncture, this past work has focused on subgrade protrusions in municipal solid waste applications. There has been limited information regarding puncture performance in mining applications, where extreme loads are encountered and angular, large-diameter crushed ore is often used as the drainage medium above the geomembrane. The attached paper discusses a laboratory puncture testing program involving various geomembranes placed in direct contact with different drainage media under high loads, both with and without underlying GCLs. Variables being examined include: geomembrane type and thickness, GCL type, normal load, and drainage stone size. Preliminary test results have shown that geomembrane/GCL composite liners are subject to less puncture damage (i.e., lower defect frequency and/or smaller puncture sizes) than geomembrane liners alone. The paper also presents a feasibility study of two lining alternatives, geomembrane/compacted soil and geomembrane/GCL composites. The feasibility study compares technical effectiveness and cost effectiveness based on cost savings associated with improved metal recovery rates afforded by improved containment. This information is intended for mining companies and engineers in evaluating lining options and allowable stone sizes. This paper was presented at the Tailings and Mine Waste ’08 Conference.
