  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • Why Water Management Professionals Can’t Afford to Ignore Innovation

    Innovation in the water management industry is born from the collaboration between water managers, operators, engineers and manufacturers who set out to resolve problems or improve service levels that impact all parts of the supply chain. This is usually the result of early adopters either at the field level or in engineering ...

  • Optimal groundwater contamination monitoring using pumping wells

    This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...

  • Well oiled machines

    On November 1, 2004, Bridgewater's first oil skimmer began removing oil from its mill drains. At a cost of $6,500, the skimmer, supplied by Abanaki UK Ltd, represents a significant investment and underlies Bridgewater's commitment to enhancing the operation of its Effluent Treatment Plant. The acquisition of an oil skimmer materialized following lengthy periods of under performance from a ...

  • Regional modeling of wells

    The ability to represent wells in a regional three-dimensional numerical groundwater model is crucial for many modeling exercises. Such wells can either be measurement wells where groundwater levels are measured as a function of time, or wells can be pumping wells in which water is removed from the well and a drawdown cone is created in the water table surrounding the well. There are numerical ...

  • Evaluation of a Horizontal Well

    Background: Air Sparging Air sparging is an in-situ remediation technology where air is injected into the saturated zone of an aquifer. It is an alternative to conventional ex-situ pump and treat systems for remediation of contaminated ground water. It is necessary to understand the pattern of air flow that will occur in the subsurface in order to determine the optimal placement, ...

  • Analytical Solutions for Free-Hydrocarbon Recovery using Skimmer and Dual-Pump Wells

    Accidental release of petroleum hydrocarbons to the subsurface may occur through spills around refineries, leaking pipelines, storage tanks or other sources. If the spill is large, the hydrocarbon liquids may eventually reach a water table and spread laterally in a pancake-like lens. Hydrocarbons that exist as a separate phase are termed light non-aqueous phase liquids (LNAPL). The portion of the ...

  • In-well Vapor Stripping - Technology Overview

    In-well vapor stripping technology involves the creation of a ground-water circulation pattern and simultaneous aeration within the stripping well to volatilize VOCs from the circulating ground-water. Air-lift pumping is used to lift ground-water and strip it of contaminants. Contaminated vapors may be drawn off for aboveground treatment or released to the vadose zone for biodegradation. ...


  • VFD for pumping systems

    Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...

  • ECSMGE CONFERENCE 2015: Managing the Clogging of Groundwater Wells

    This is the poster or summary of a paper being presented at the XVI ECSMGE  - European Conference on Soil Mechanics & Geotechnical Engineering - in Edinburgh from 13th to 17th September 2015. Groundwater wells are common to many civil engineering projects and their operational performance can play a crucial role. The wells may be part of a construction dewatering system, ...

  • Modeling geothermal wells using SVHeat and SVFlux

    Numerical modeling of geothermal processes has received increased attention in recent years. The process of installing geothermal heating systems in residential homes and cottages is one application of numerical models. These systems typically involve drilling between one and three wells on a particular property. Heat exchangers then act as a pump and remove heat from the ground in order to heat ...

  • JP-4/JP-8 Bioremediation Using ORC® Pumped into Permanent Injection Wells (PDF)

    At Nellis Air Force Base, Nevada, a site investigation revealed that two separate floating product plumes and a larger dissolved plume consisting of JP-4 and JP-8 jet fuel existed. Floating product thicknesses ranged from less than one-half inch to almost three feet. The length of the dissolved plume extended about 700 ...

  • Four steps well owners can take to protect their water wells, health during flooding

    The owners of private household water wells in areas of flooding should act to address possible threats to their drinking water quality, the National Ground Water Association said today. If a well has been flooded: Do not drink the water or wash with it, but use an alternative supply such as bottled water Stay away from the well pump ...
