Measuring groundwater level or depth-to-water is critically important for identifying long term trends, including declining water levels, saltwater intrusion, seasonal variations, aquifer recharge, artificial aquifer storage and recovery, and level status for drinking water. Receiving groundwater data via remote data transmission from one of the many OTT telemetry options available saves time and resources spent in the field.
WesTech provides process equipment for the sand aggregate industries including thickeners, screening and separation, and mixing technologies which provide for production of cement, and a myriad of materials for the construction industries.
The content of water-soluble forms of inorganic cations (ammonium, potassium, calcium, sodium, magnesium) is one of the substantial characteristics in agrochemical, land reclamation, and sanitary assessments of soils (arable, hayland, pasturable, forest nursery soils). The cation balance should be controlled during ecological soil monitoring for the human activity impact assessment.
Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil; the main and most specific part of these compounds are non-polar and slightly polar hydrocarbons of the aliphatic, aromatic, and alicyclic structure.
Presence of fatty acid methyl esters (FAME) in diesel fuel or domestic heating fuel (both hereinafter referred to as diesel fuel) is a signal of blending with biodiesel. The control of FAME content in diesel fuel is an essential and actual task because of the need of the right fuel identification and registration of possible FAME impact on engines and fuel systems. To control the compliance one of the most accurate, rapid and simple methods is EN 14078:2014.
Analysis of soils and bottom sediments for mercury content is one of the most common analyses in the monitoring of environmental pollution. Background mercury concentrations in these objects are 10–100 μg/kg and in the polluted areas they exceed 10,000 μg/kg.
Spraying Envirotac on loose soil binds the soil particles and does not let the them be carried into the air, preventing dust pollution, thus reducing dust allergies and other respiratory problems. One application will control dust for over a year at a fraction of the cost being spent maintaining with water.
Purolite is at the forefront in meeting the new challenges of purifying water for potable water use. We continue to develop specialized ion exchange resins and adsorbent solutions focused on reducing waste and operating costs. The wide variety of contaminants needing removal often requires a customized approach.
Envirotac line of polymers has been effectively used as a sub-base for roads, out-performing a standard rock base in performance and significantly in cost. Envirotac has been a preferred choice by many Departments of Transportation, replacing rock base and then having a cinder seal or chip seal sprayed over.
Being able to trust your instruments to make quick, easy and accurate measurements in the field is key when dealing with regulatory requirements. The InfraCal2 infrared analyzer is the choice of experts for measuring oil in produced water; oil contamination in soil; and fats oil and greases in waste streams.
Groundwater hydrology is an interpretive science: we can’t observe the aquifers directly so we must interpolate and extrapolate our understanding from water-level measurements taken from observation wells. Stevens has expertise for measuring both water quantity and water quality.
Nanoremediation represents a modern method of treatment of environment polluted by chlorinated hydrocarbons, heavy metals, radionuclides and other contaminants. This technology started to be used tentatively in USA and it already takes place on various sites around the world at present.
Several industries and industrial processes may contribute to soil and groundwater contamination. AdEdge Technologies has supplied filtration equipment for several remediation efforts to remove arsenic, lead, and other inorganic contaminants to meet state and federal mandates.
Hydraulic Erosion Control Products (HECPs) are engineered mulch applied to slopes to reduce soil erosion while assisting in the establishment and growth of vegetation. An alternative to temporary Erosion Control Blankets (ECBs), hydraulically applied products can be installed up to three times faster using one-third the manpower. North American Green`s HECPs are applied in a one-step application with seed and fertilizer, with the potential for quicker installation and project cost savings compared to products...
Slopes can present serious erosion control challenges. In addition to the effects of runoff and the need to protect wildlife, there are issues of aesthetics, and, of course, budgets. That is why project designers prefer the value, aesthetics and safety offered by soft armor solutions - especially those from North American Green’s complete line of erosion and sediment control systems.
Dredging is the process of removing organic and/or inorganic sediment from the bottom of shallow water bodies in order to economically dispose of those sediments and/or have them repurposed for land farming or construction purposes. Elgin Separation Solutions manufactures effective solid recycling systems capable of handling high flow capacity. Elgin`s linear motion shakers have the largest screening surface area on the market. In addition, we have complete desilter and desander hydrocyclone manifolds incorporated...
