Guardian Blue Early Warning System

Guardian Blue Early Warning System

Is the Nation's drinking water supply safe from terrorist attack? In overall, the danger of corruption of drinking water complete by terrorist activities is small but it can still happen. Many do not realize that a lot of contaminants would need to be utilized in very large amounts, in that way reducing a definite threat. Treatment procedures previously in position will disable many pollutants. Also, succeeding the disastrous proceedings of September 11, 2001, drinking water utilities all over the county were forewarned regarding the need to upturn security and have increased shadowing and protection actions. GuardianBlue is one of those protections that can be used in these extreme cases. GuardianBlue is basically the first and solitary waste product warning system that is actually certified and elected by the United State Department of Homeland Security for checking drinking water.

This system is influenced with the power of the Agent Library. This powerhouse is also equipped with the unique, exclusive agent library, the GuardianBlue Event Detection System is intelligent enough to be able to detect and categorize the 34 pollutants of highest interest to drinking water contractors and USEPA. The system is able to do a phenomenal job in perceiving water quality proceedings that are within the minutes and reports of the pollutant complemented in the agent library -- effortlessly distinguishing among fluoride overfeed, insecticide corruption, warfare agents and cyanide.

Again, Since 9/11 there are numerous communities that have been installed multi-parameter monitoring stations in many place all over the distribution system as early warning systems founded on possible water security threats. These incessant online systems have chronicled huge torrents of information that is pertinent to water quality in the delivery arrangements in which they have been deployed. In this study data streams from a number of communities (both small and large) are analyzed for pertinent information as to the health and operation of the distribution system.

Changes in water quality are correlated with known causes attributable to day-to-day operational changes (source water switching, chlorine shocking, pumps turning on and off, pressure surges) and also anomalous events (pipe bursts, accidental back flows, cross connections, chemical over feeds, treatment plant problems, nitrification events, etc.). Information concerning what if any action was taken to ameliorate the problem will also be linked to the data for the identified events. The data streams also show the diversity in what could be termed "normal" operating conditions both within and between different classes and types of systems. This sort of information is critical in understanding and improving the operation of their distribution systems and can also be valuable as we consider regulations that effect that operation.

With GuardianBlue it can quickly pick up common water quality events. GuardianBlue Event Detection System is likewise well-appointed with the competence to learn water quality events which are very unique to the water that is being observed. Users of this system are labeling the learned events, and ascribe an importance level, authorizing the GuardianBlue to log and prepare users to innovative and recurrent proceedings.

GuardianBlue is the first and only Early Warning System for drinking water to have earned the Safety Act label and certification from the U.S. Department of Homeland Security. "Designation" denotes the product has capable as an anti-terrorist technology, even though "certification" just says that the creation is accepted for homeland security. GuardianBlue's Event Monitor, Water Panel and TOC Analyzer have really undergone Environmental Technology Verification that was from the EPA for constant multi-parameter water watching in distribution systems. Hach's GuardianBlue Early Warning System has been able to be alarmed on at least 100% of all contaminants that are being injected into the system throughout the ETV.

The System of GuardianBlue Event Detection System

The Event Monitor examines all of the sensor data which is derived from the Water Panel and then to the TOC Analyzer. All of this is what will help identify if the water has been tampered in case of a terrorist attack. Just in case that there is an assault on our water supply, about every 60 seconds later, the structure begins to start applying a patented procedure that goes straight to the sensor measurements, then it calculates the site's water quality reference point. The structure sends and alarm right when the trigger indication starts exceeding a user-set beginning, representing a water eminence called the "event." The event fingerprint is what is associated to something like the fingerprints which are being deposited in cooperation the Plant Library and the Agent Library, and warns service supervisors when a match is suddenly discovered. If there is nothing that is being matched or found, utility operators are made aware to an unidentified deviancy in water feature and the affair's impression is placed in the Plant Library for additional examination, documentation and cataloging (Berry, Hart and Phillips).

Event Monitor

Positioned among the Event Monitor, the Agent Library remains as being the most scientifically sophisticated analytics software that is accessible for water quality checking. The Agent Library comprises of fingerprints which are utilized for a broad assortment of threat impurities. When the Agent Library counterparts an occasion with the fingerprint of a risk impurity it also provides the gradation of sureness in the arrangement in helping operators in making sure that decisions have appropriate responses and decisions.

Water Panel

The Water Panel unceasingly screens free or entire chlorine, pH, turbidity, conductivity, temperature and compression which it directs to the Event Monitor by means of digital communication. As soon as an event happens, the Water Panel starts detecting alterations in the water quality limitations. The Water Panel is included of Hach's foremost water excellence devices and has turned into a typical commerce for water quality checking.

TOC Analyzer

The TOC Analyzer uninterruptedly displays complete carbon that is considered to be organic. The TOC Analyzer utilizes EPA method which is around the amount of 415.1 and this is done in order to attain its capacities guaranteeing precise outcomes (Hach Company GuardianBlue Early Warning System). The TOC Analyzer is a key component of GuardianBlue, providing increased sensitivity to organic contaminants.

Automatic Samplers

Whenever the Event Monitor goes into its triggering mode, it promptly motions the Automatic Sampler to start capturing a real-time water sample. This then permits water conveniences to start conducting added forensic inquiry and difficult on actual water models as quantity of an answer plan.

At one time, checking of operational strictures in the distribution system has really been operated in a piecemeal and disorganized way. In order for the GuardianBlue Event Detection System to have an intended impact on its attackers, it needs to be understood that the distribution system represents the last logical frontier in the water quality business (J. & . Roberson). With this system, that attackers would realize that the monitoring of our source water and treatment plant processing have proceeded to a level where the U.S. Department of Homeland Security can be confident that we are giving decent quality water (Bennett). The attackers would know that once the water influences the aging delivery systems, the knowledge as to its constant reliability is restricted by the excellence and quantity of obtainable information.

The attackers would soon find out that a lot of the monitoring in the distribution system is transferred to the sporadic snapshot that is delivered by grabbing specimen for a few narrow strictures or the uncommon regulatory testing which is always necessary by directives for example the Total Coliform Rule. However, know that since 9/11, utilizing the GuardianBlue Event Detection System has upgraded things and made the system even better.

Attackers would soon learn that we have learned from our past. Since 9/11 numerous communities had started installing multi-parameter checking positions in numerous sites all over the distribution system as early warning systems founded on potential water safety dangers (Vary). Attackers are unaware that these continuous online systems have and are in the process of recording huge torrents of documents (some locations for a quantity of existences) relevant to water quality in the distribution systems in which they have been deployed.

Analysis of GuardianBlue Event Detection System

The GuardianBlue has a lot of strength and weaknesses. One of those strengths is that the GuardianBlue can be set up on the floor or even the wall. This is a benefit because setting up on the wall only requires somewhere about 10' w x 5' h, with the auto sampler ranging roughly 3' from any wall where it can be mounted. Installation is very easy because it only needs to stands on the floor and it just requires a little more space.

The water distribution system also can be susceptible to accidental exposure to unwelcome water quality activities. In this real-life scenario, for example, the water service had been forced to relapse to the operation of a dissimilar water treatment plant despite the fact maintenance was being done to the new plant. A pump that had been accountable for treating fluoride into the preserved water broke down thus producing the dose to upsurge over periods of time. When the overindulge had taken place, the GuardianBlue Early Warning System not only alarmed but also categorized the probable reason of the problem to be a fluoride overfeed. This then permitted a quick reply before customers of water were unprotected to possibly hazardous heights of fluoride. Fluoride, while deadly at reasonable to high doses, is usually measured helpful for dental health at doses that were very low. The most normally suggested dosage of fluoride for individuals is 1 mg per day.

The GuardianBlue has strength when it comes down alarming things way ahead of time. A lot of people are not aware that the GuardianBlue system had alarmed almost three full days before a catastrophic pipe burst and had noticed pipe burst proceedings in a lot of key United States cities? It is accurate, consuming its' distinctive algorithm with often checked limits, GuardianBlue had seen a change in both the conductivity and chlorine which is at the same time. Generally these specific variations are well thought-out as small enough and are not noticed by the human eye, but the algorithm saw the nonconformity and ongoing disturbing roughly 70 hours that happened before a 36? main broke, dropping millions of loads of water straight into downtown. It was noticed that the pipe had a crack that was small, which is the reason for the conductivity and chlorine that altered, by reason of reduced water age. Around 3 days later, the disastrous break happened. The arrangement was 2 miles upstream from where the break had occurred. This specific borough could possibly name this occasion in the Plant Library, and should it observe a comparable impression, the event monitor would remember the name provided in the Plant Library. The EPA has sonce quotes that the usual pipe breaks prices about $28 million dollars in patch-up and lost income.

Another one of the strengths regarding the GuardianBlue Event Detection System is its reliability. There was an incidence where a drinking water facility on a military base was constantly getting phone calls from customers of their water who were irritable of a weird taste and scent. Every time a person would call in, somebody from a drinking water plant worker would go to a water sampling place in the distribution system and then they would run a test on the water. After several unsuccessful attempts at trying to figure out the cause of the odd water and persistent complaints, the GuardianBlue Event Detection System was installed. This device then monitored the water excellence on a continuous basis and consequently made it easier to reply and associate the poor water quality to the criticisms (Bush). They exposed low flow places and dead heads that are among the distribution system. With knowing this new material in hand, the plant operators enhanced their blooming agenda and importantly improved the water quality ensuing in no more grouchy phone calls.

Some of the weakness of the system is the alarm system. Agent alarms in the system cannot be systematically tested since the agent list is patented and supposed agents are dangerous to work with. Basically the third party testing with thirteen concrete agents has been accomplished by the EPA and Battelle in an Environmental Technology Confirmation analysis. Results of these studies confirm that the GuardianBlue is capable of precisely categorizing agents.

Cost

One thing good about the GuardianBlue is that it is very cost effective. Why? Because the first priority for any event detection system is that it does a low-priced detecting of contaminants so that people and organization can be protected in some effective way that does not cost that much. Though the capability to perceive contamination is serious, if a system is to be accomplished of proposing a probable return on investment (ROI) and attain extensive deployment (Hach Company GuardianBlue Early Warning System). It is presumed that the GuardianBlue Early Warning System spends extremely little of its entire time in a definite alarm condition. So the question is what is going on with it for the rest of the time? Justification of the cost can include the following:

1. Optimization of day-to-day procedures in the interior the system monitored,

2. Provided that alarms for effective events not correlated to pollution threats,

3. Substitute grab sampling for observance with other procedures with unceasing monitoring,

4. Document system operation differences to support with planning upkeep activities or scheduling and modifying major organization elevations (line replacement)

5. Constructing consumer self-assurance by constantly system water excellence

Such proficiencies can reduce the cost of procedures for the system that is being monitored, and arrange for evidence that can be beneficial to those people who utilize the monitored system.

Acceptability of the GuardianBlue Early Warning System

The GuardianBlue Early Warning System is acceptability is vital to plants employees, neighbors, and leadership. The capability to normalize the sensors and manager by using a single manufacturer has recognized to be cost-effective in the long run for employees and neighbors (Drinking Water Contamination Warning Systems-Design and Implementation of an Online Water Quality Monitoring). Years in the past, when the GuardianBlue Early Warning System plant was in its design stage, bids had been taken in order for the initial pump station basis water monitoring instruments and analyzers on an separate basis and the low-price bidders were granted the jobs. But the succeeding complications ascending from opposing plumbing and wiring necessities, large space consumption, and the probability of polluting and other accuracy-harmful effects soon worn the original cost savings.
