Arsenic is a naturally occurring element found in soils and groundwater. Arsenic concentrations vary in accordance with geographic location. When arsenic levels are found to be too high at a specific location, it may be necessary to treat water to remove it. Arsenic usually exists in two different forms, or valences, in a natural setting depending on the amount of oxygen available in groundwater. In more shallow aquifers with higher levels of oxygen, arsenic will usually exist as arsenate, As (V). In deeper,...
STS has been a hydrologist partner for many years, and through this work we have developed the experience to become specialists in the monitoring of river, lake and ground water levels. Measuring groundwater level 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.
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.
Allegheny Instrument's Nano downhole camera is used to visually inspect groundwater monitoring wells from 1-inch diameter and larger to depths of 1,000 feet with the Heavy Duty hand reel system and depths of 2,000 feet with the Deluxe motorized winch.
Landfill leachate is the runoff water that occurs from operational or closed landfills. This water flows at lower rates on dry days when naturally occurring moisture percolates out and at higher rates on rainy days when the leachate waters are combined with stormwater.
In construction and infrastructure field GPR application makes it possible to have the most detailed topography of undergrounding. GPRs help to discover ground water location, old underground passages and cavities remains and karst layers.
The geotextile performs two primary functions when used in the construction of tunnels:-
1. Protection of the linear from abrasion and puncture by protrusions from the base surface of the tunnel well.
2.Drainage of water seeping through the rock and sprayed concrete layer. The in-plane oermeability of the geotextile enables the water to flow to a subsurface drainage collection system. where it is directed awa from the tunne
Vacuum excavation is fast becoming a best practice in the field of construction and site excavation. Why? Because it uses jets of air (air excavation) or water (hydro excavation) to loosen soil, instead of a heavy metal claw. After loosening, the soil is pulled out of the ground through an air vacuum hose to a debris tank for later disposal or back-filling. Using non-destructive technology can quickly, safely and economically excavate in areas inaccessible to conventional digging equipment like backhoes and...
The organization model of irrigation at the same level of the basin is considered one of the best ways to use efficiently the available water and the management of this resource. One of the most successful examples of this kind of Management is the Watering Communities. These communities are consortium of farmers in charge of the organization of the use of public, surface and subsurface water.
ENTACT has successfully completed projects at a wide variety of transportation facilities including ports, rail systems, terminals, and airports. These projects typically require elaborate traffic control precautions as well as sophisticated shoring systems for protection of critical infrastructure. Our safety culture and in-house geotechnical expertise put us in a position to add significant value to complicated transportation related projects.
Piper Environmental Group, Inc. has partnered with Primozone Production AB in Löddeköpinge, Sweden for our municipal, groundwater, and wastewater applications. Our successful installations since 2015 have made our choice an obvious one. Primozone’s applications are in 30 countries worldwide, with documented OPEX (Operating Expense) savings that are key for companies and utilities who truly believe in a low carbon footprint, sustainability, and reducing their operating costs in maintenance, electrici...
VIY3 GPRs allow to have a topography of subterrain structure down to 15 meters. That the good application for underground water exploration, searching for harmful chemical pollutions and underground cavities finding.
Robust platforms with high data throughput and calculation capacity are required for the continued reliable operation of decision support systems. KISTERS solutions continue to be the preferred choice by organizations around the world needing these types of systems.
