An Introduction to Soil Remediation

Soil Remediation?

Soil remediation is part of a broader process called environmental remediation. It is the collective term used for different techniques used to purify and revitalize soil. Problems are generally caused by contaminants which are substances either currently causing undesirable effect or will possibly cause an undesirable effect in the future. The main aim of remediation efforts is the reduction of these contaminant concentrations within the soil to lower levels so that land area will be more suitable for use without the environmental risks.

There are a lot of various methods which can be applied in dealing with soil contamination, and some more effective than others. In selecting the most effective method, it is important to know the following: its impact on other surrounding living things in the vicinity, nature of soil contamination, and how successful the activity is projected to be. It is possible for an area to go through multiple soil remediation processes to handle multiple contaminants.

Soil Remediation Methods

As with other environmental problems, topsoil remediation processes can be put into three major categories:

1. Soil Treatment - reduce amount of contaminants to safe levels

2. Physical removal - eliminate the concentrations entirely

3. Stabilization - combine the contaminant with other substances to remove the risk of the contaminant

Soil remediation is sometimes done by eliminating contaminated ground water then purifying the extracted liquid. This process is known as pump and treat. The soil is also extracted and contaminants are removed by filtering, and then returned to its original location.

Excavation and dredging may be considered among the most common processes used in topsoil remediation. This process involves setting aside a landfill for contaminated soil which is extracted using current technology. The contaminated soil is transported to the landfill and purified soil is often used to replace the area where the contaminated soil was extracted.

Now, newer and more effective methods are being developed, thanks to the fast advancement of our current technology. Most of these efforts for soil remediation are structured at national government levels to rid the ground of harmful contaminants making it suitable to be used as dwellings, farms, and wildlife habitat. In the United States, the Environmental Protection Agency, or EPA, issues directives on the approach to soil remediation. These directives are collated to form the country's soil remediation standards. The Council of the Ministers of the Environment in Canada provides support to each province's efforts of remediation. The United Kingdom and Australia are also two countries known to actively engage in land remediation strategies.

Basic Breakdown of SCADA Systems

SCADA is the acronym for 'Supervisory Control and Data Acquisition' and the term is generally applied in the context industrial control applications, facility processes or infrastructure management. A SCADA system includes not just a supervisory computing unit for acquiring data and sending commands to a system but also Human Machine Interfaces (HMI's), Remote Terminal Units (RTU's) and Programmable Logic Controllers (PLC's).

It is worth noting that in the past a distinction was made between SCADA and Distributed Control Systems (DCS's) but that the differences between the two systems are becoming less defined. Both technologies have advanced to provide quite similar monitoring and control solutions in more recent times.

Most of the control actions in a SCADA system are automated by RTU's and PLC's based on preset requirements. RTU's connect sensors within the process by sending digital data to the supervisory 'computer' and whilst PLC's fill a similar data acquisition role they offer more versatility and are customisable to perform more specific automation tasks. Newer and increasing applications of 'smart' PLC's and RTU's allow these components to manage non-critical or routine tasks autonomously without drawing on the resources of the master computer.

Operators and system maintenance personnel utilise the HMI (Human Machine Interface) in order to review various portions of data within the system. The Operator will then use this data to control various aspects of the process. In most cases the HMI is linked up to the SCADA system's software and databases and it is set to provide trending data and diagnostic data. Technical information examples include machine or sensor schematics and expert-level troubleshooting guides. Management information examples include logistics data, productivity data and maintenance schedules.

HMI's are often set to display data in graph and diagram formats for ease of interpretation. Such routine 'reports' and schematics are just one aspect of the SCADA HMI. Arguably the most important function of the SCADA system is that of alarm handling. The system monitors all aspects of a process and when certain 'alarm' conditions are met one or more actions occurs such as notifying the operator via email, text or the system itself. It is important to discuss cascading alarm handling with the SCADA engineer or a similar professional to ensure that the initial alarm event is not lost beneath subsequent alarm triggers.

A universal requirement for SCADA systems is that they are built and installed with durability and reliability in mind. Components need to be hardy and able to withstand varying temperature ranges and vibration levels, well as extreme voltages. Systems of critical importance would be setup with built in redundancies (in hardware and communication), multiple servers and disaster recovery sites sometimes to the point of having multiple control centres which are fully equipped to take over failed processes and operations.

All-in-all, SCADA and its related HMI's are a vital part of many aspects of modern production and process control. From space stations to water treatment facilities to refining plants to controlling energy consumption in a building, there is a SCADA based system application available to report on and control its processes.

Preventing Metal Corrosion by Reliable Cathodic Protection

Cathodic protection is by far one of the most efficient techniques when it comes to management of metal corrosion on metal surfaces. It works in the electrochemical cell in the form of a cathode. When it comes to safeguarding and protection of water pipelines, fuel pipelines, steel, pier piles that are made out of steel, underground storage tanks, oil platforms etc, cathodic protection is your one stop solution.

Cathodic protection also prevents cracking and stress corrosion. Metal corrosion and product deterioration occurs on a constant basis. Hence, in order to avoid it, UST testing procedures must be undertaken on a regular basis. Since there are tubes, connectors, pipes made of metal and storage tanks that are located below ground level, they need to be regularly monitored to avoid hazardous corrosion. Cathodic protection handles metal deterioration in a way wherein the underground storage tank becomes the cathode as part of an electrochemical cell.

It is only by finding the right reliable UST compliance testing provider that can carry out regular fuel inspections, tank leak detections and offer valuable solutions for infiltration of fuel. This can deliver great performing petroleum and underground tank systems. It also concentrates on consistency for all products thus enabling great performance. Once done on a consistent basis, your company can instill systematic inspection procedures at regular intervals.

By conducting surveys time and again your cathodic protection methods can improve considerably. This also leads to huge expenditure savings as they are cost effective solutions. Tank testing and UST leak detection procedures must be dedicatedly followed if the outcome is to be positive. If constant check on their underground storage tanks, pipes and petrol systems are undertaken, companies can be rest assured to possess competitive and dependable products. This can lead to great profits and business expansion in future.

Data Monitoring Systems - Why Are SCADA Systems Important?

Data monitoring systems such as SCADA are becoming more and more relevant in today's business environment. SCADA which actually stands for supervisory control and data acquisition is a system that is being used by a variety of businesses nowadays. The entire system is actually a well planned network of interconnected computers. There are a number of remote terminal units that do the process of collecting data from the field and sending it to the central station master, through the network of the communication system that is in place.

One of the biggest advantages with the system in place is the fact that the top management always has timely and accurate data available to them at any time. The real time data can be used by them to optimize the operation of a plant or a business process. The system enables considerable improvement in the efficient running of a plant. Moreover, it also ensures data safety, another crucial aspect that needs to be considered by businesses today. When viewed from a company's perspective, the system is invaluable, with it lessening the operating cost quite significantly. The efficiency of the system directly translates into higher profits for businesses operating in various different sectors.

It is important that SCADA systems are used by competent staff that is well trained on using the system. There are times when companies may not pay heed to this important aspect in their eagerness to install the system. There are software complexity issues that need to addressed by the top management while they go about the process of implementing the system. The smooth running of the system needs the perfect and coordinated running of the different components that make up the system. For example, it is just not enough if the communication links are working properly, because it is also important for the transducers and control devices are also working in perfect coordination with the rest of the system.

Well planned data monitoring systems form the lifeline of industries these days. It is important that businesses also take care of training their staff on SCADA systems for it will help in maximizing profit and the smooth running of the business.

Cathodic Protection - An Effective Way to Prevent Metal Corrosion

Cathodic protection is a well known technique to manage the corrosion of any metal surface in a manner by getting it to work in the form of a cathode of the electrochemical cell. Cathodic protection testing is a very favourable option to consider in order for the protection of steel, water pipelines, fuel pipelines, storage tanks, pier piles made of steel, ships, oil platforms and many others. Cathodic protection is also to relieve stress corrosion or cracking.

Cathodic protection testing is a very effective method in order to prevent metal corrosion and deterioration. UST testing needs to be regularly run in order to avoid such mishaps. UST compliance testing is a widely considered alternative to counter metal corrosion. Since underground storage tanks, metals, pipes, connectors or tubes are located in the ground, they frequently come in close contact with soil. This is where the corrosion appears. If not treated at the earliest, it can prove to deliver harmful results. With the appropriate use of direct electricity current in order to curtail any sort of corrosive action, procedures for cathodic protection testing takes care of metal deterioration in a manner that makes the underground storage tank the cathode of an electrochemical cell.

In order to constantly battle these issues or avoid them, companies must search and locate an efficient and favourable UST compliance testing provider. Since, UST compliance testing providers undergo frequent fuel inspections, UST leak detections and provide remedies for fuel infiltration, you can be ensured that your petroleum systems will operate very smoothly. Corrosion experts make sure that there are no interruptions with cathodes and confirm that the cathodic protection procedures followed are fool-proof and beneficial. A regular system check every 60 days is a must. This enforces consistency on all the products and systems performance. Cathodic protection testing enables your company to initiate a technique of up keeping your equipment.

Cathodic protection testing involves certain necessary methods of operation such as regular surveys in order to ensure the system installed is genuine. They also provide the most cost effective system to save up on maintenance expenditure. Other surveys for inspection on UST leak detection and corrosion of the underground storage tanks are also undertaken. If petroleum companies can work towards a regular check on all their devices, products and other equipments, they can assure themselves of having a good performing storage tanks. If tackled with urgency and through inspection, these hindrances can be kept clear of. All one needs to do is find a suitable and fine UST compliance testing provider to counter the occurring problems in time.

What are SCADA Systems?

SCADA is a word that is used mostly to portray management and control solutions in a broad range of businesses. Some of the businesses where SCADA are used are Electric Power, Water Management Systems, Mass Transit Systems, Manufacturing Systems, Environmental Control Systems, and Traffic Signals.

SCADA as a System

There are several parts of a working SCADA. A SCADA-system generally takes account of signal hardware (the input and the output), networks, controllers, communications equipment, user interface (HMI), and software. At one fell swoop, the word SCADA refers to the entire central system. This central system typically monitors information from different sensors that are both off-site or in close proximity.

User Interface (HMI)

A SCADA scheme comprises a user interface, called "HMI or Human Machine Interface." The HMI of the SCADA scheme is where information is processed and offered to be monitored and viewed by a human operative. This interface typically incorporates controls where individuals could interface with SCADA system.

HMIs are easy means to standardize the facilitation of viewing and monitoring numerous PLC's or RTU's. Usually PLC's or RTU's will run a pre-programmed procedure, but monitoring all of them individually could be hard, typically because they're spread out all over the scheme. Since PLC's and RTU's historically had no consistent method to show or present information to an operator. The SCADA system corresponds with PLCs all through the network system and processes details that are easily dispersed by the HMI.

SCADA Hardware and Software Components

SCADA systems are extremely advantageous means to monitor and run processes. They are truly great for small applications like control of climate or could be efficiently used in big applications such as controlling and monitoring a mass transit system or nuclear power plant.

SCADA could come in an non-proprietary and open protocols. Smaller schemes are exceptionally reasonable and could either be bought as a complete system or could be matched and mixed with particular components. Big systems could as well be made with off-the-shelf components. The SCADA scheme software could as well be simply configured for approximately any application, eliminating the necessity for intensive software or custom made development.

April 29th Is Earth Day Solano In Suisun City With Community Participation In Garbage Art And More

Public welcomed to participate in Saturday, April 20th
experience with Solano County leaders

Suisun City, CA - Mission SOLANO, local artists from the Fairfield Visual Arts Association and the Lawler House Gallery, along with Earth Day Solano volunteers, will create six pieces of unique “garbage art”, created from the trash collected throughout Suisun City on Earth Day Solano, Saturday, April 20th from 10 am – 2 pm.

Three years ago the Earth Day Solano vision, inspired by the gorgeous downtown waterfront in Suisun City, blossomed:

You allowed us to clean up your discarded, thrown away,
trampled-on refuse; we recycled it and now present you with
a piece of art, more beautiful than you thought you could imagine.

This year’s Earth Day Solano art project – six pieces of original art created on the spot on Earth Day April 20th using trash collected from Suisun City targeted cleanup zones – glows as a tangible expression of the Mission SOLANO vision for recycling people. Inspired by the documentary “Waste Land” by artist Vik Muniz, artists came together under the leadership of artist, Aria Zuloaga to plan the art project. “

After watching the movie Waste Land, a group of us from Lawler House Gallery and the Fairfield Visual Arts Association collaborated to create the concept and images for six temporary live art installations on April 20th,” Zuloaga reflects. “We believed in this project from the beginning and after weeks of preparation we’re anxious to see the images and the art unfold. It is a labor of love for our community and for our planet.”

Art became a central part of Earth Day Solano in 2012, when Gilbert Rangel, local esteemed recycled materials artist, created a piece of recycled metals art now on permanent display in the city chambers of Suisun City (see below).


For additional details on the Earth Day Solano April 20th event, including trash cleanup, Kayaks 4 Kare sprint races, tree planting, Earth Day oratorical competition, 30 participating vendor booths and more, visit

Groundwater Remediation, A Pressing Need in Today's Times

Water pollution today has reached alarming levels in most parts of the world. Surface freshwater bodies like ponds, lakes, streams and rivers have become increasingly polluted. This has resulted in groundwater becoming an important source of drinking water in many countries. In the U.S alone over half the population depends on groundwater supply for daily water needs. Groundwater is today used for a variety of purposes from agriculture to industrial, to irrigate large farms as well as in the production of goods.

Groundwater pollution causes

Increased human activities like construction and mining have resulted in pollution percolating into natural groundwater reservoirs. Some of the causes of groundwater pollution also include stagnant storm and rain water as well as surface water runoffs containing high amount of chemicals and organic waste like sewage. This results in large scale contamination of groundwater resources rendering it unfit for human use.

Groundwater remediation

Along with waste water treatment plants which seek to use recycled water, groundwater remediation has also become an important initiative to provide safe and clean water for human use as well as conserve the environment. Groundwater remediation involves specialized equipment and experience to conduct the various purification operations. Groundwater filtration involves removal of solid and dissolved impurities which includes organic material, chemical substances as well as gaseous elements.

Different remediation techniques

There are different techniques used to purify groundwater. An effective method involves use of vacuum machinery to pump out groundwater for treatment as well as extraction of gaseous vapors from ground water and soil. The method known as dual phase extraction makes use of carbon adsorption process by way of granular activated carbon filters and portable water filtration units.

Most groundwater remediation techniques use a combination of different methods for water purification depending upon the requirements. For example if the groundwater contains a high concentration of heavy metals then chemical precipitation reaction is used to ensure conversion of the metal ions into insoluble compounds. These particles are then removed by way of simple filtration or by way of settling chambers.

Activated carbon particles

Activated carbon is an important part of the purification process owing to its high surface area which causes organic impurities to chemically bind to the carbon particles. This process is known as adsorption and is highly efficient in removing dissolved organic impurities which even boiling the water does not render harmless. Active carbon is used in the form of fine granules spread out over a wire mesh to further increase their surface area for maximum effectiveness.

Groundwater remediation is an important aspect of maintaining public health and as such should be conducted at regular intervals by the concerned health authorities.
