To line, or not to line? That is the question! In a world where compacted clay liners were the norm for many types of containment systems, it is becoming more common for project engineers to specify a geosynthetic lining system. Geosynthetic lining systems have proven themselves as a more effective, cost-saving method of containment. This can be achieved while inhibiting
Stormwater has become a hot-button topic for environmentalists and city managers alike. Environmentalists see stormwater as a mode of transportation for pollutants into area waterways. City managers see it as a nuisance and the cause of flooding in the ever-hardening landscapes of metropolitan areas. It is true that stormwater generated by hardened landscapes should be captured to reduce flooding and
The HydroTurf® Revetment System is an ideal solution for a wide array of applications where stormwater and exposed soils interact. Soil erosion is an issue plaguing both the man-made, and natural environment. The increase in frequency and intensity of storms due to climate change has created the need for increasingly engineered approaches to deal with stormwater while keeping soils intact.
Traditional stormwater systems throughout the country are aging. Meanwhile, municipalities are struggling to find cost-effective means of managing wet weather events. Traditional stormwater systems collect rain and/or snowmelt and carry it via piping networks to a nearby waterway, or wastewater treatment plant. In cases where stormwater is delivered directly to waterways, pollutants can be carried and deposited without any mitigation.
Agricultural Waste Lagoons and Storage Ponds — What goes in, must come out! We Americans love our meat and dairy, but most put little thought into the waste produced by the animals that bring us these tiers of the food pyramid. The U.S. Department of Agriculture estimates that the United States produces
Fish hatcheries are the lifeblood of our Nation’s commercial and natural fisheries. They provide a steady supply of fry (baby fish) to supplement lakes, rivers, streams, and commercial fish farms. Factors such as overfishing and invasive species have and will continue to have a detrimental impact on fisheries, which could collapse if not augmented with hatchery stock. Our team at
Stockpile covers are fundamentally large tarps that protect merchandise being stored out of doors until it is either processed or moved to its intended destination.
Many external factors can damage stock that is stored outdoors without the proper protection. These include UV degradation, wind, precipitation and mechanical or animal tampering. Some vendors do not
PFAS & Geosynthetics Update: The Environmental Protection Agency (EPA) has released their mandated PFOA and PFOS Diffusion through LLDPE and LLDPE Coextruded with EVOH at 22℃, 35℃, and 50℃ . This document is open for public comment until February 22, 2021. It details three current techniques for abatement of PFAS in the environment including: thermal
Presently, the main issue regarding PFAS contamination within the geosynthetics industry is identifying the best types of materials for containment. In many cases, PFAS contaminated soils are being contained on-site by using rain-shedding techniques employed elsewhere in the pollution mitigation industry. By installing a geosynthetic barrier over the PFAS contaminated soils, also known as “capping”, precipitation is kept from infiltrating
