A Visualization is Worth a Thousand Data Points

Visualize environmental data with Locus EIM.

You’ve probably heard the saying “A picture is worth a thousand words”. While the advice seems timeless, it actually is fairly modern and started with newspaper advertisements from the 1910s. Furthermore, it’s only since the 1970s that cognitive science has caught up and determined the truth in the saying. Basically, humans have very limited working memory, which is the “storage space” for processing data while making decisions and reasoning through problems. A good picture, though, works as “offline storage” that lets you push information out of your limited working memory and into another format for use as needed. This advantage is especially true when the picture is a useful data visualization such as a chart or map. In this case, you could say “A visualization is worth a thousand data points”.

How limited is working memory? There is a rough consensus, known as Miller’s law, that you can only have “seven, plus or minus two” items in memory at one time. Think of a typical 10-digit phone number that you may need to memorize for a short period. It can be hard to remember all ten individual digits as one large number, as that exceeds working memory. However, you can employ a technique called “chunking” to group items together, reducing the number of items to remember. If you group the phone numbers into the typical ###-###-#### pattern, you only have to remember 3 chunks of 3 to 4 items. A good visualization not only stores information offline, reducing pressure on your brain; it also groups many data items into a much smaller number of chunks so you can process the data more efficiently.

Let’s look at some real examples of how visualizations help by working through a typical scenario using EIM, Locus Technologies’ cloud-based application for environmental data management. Assume you manage a site where you are tracking tritium (H-3) levels in groundwater using a set of monitoring wells. You want to know where tritium has been high over the past ten years. EIM provides different visualizations for exploring your data and finding the answers you need.

First let’s just look at an export of all the data. Using the analysis functions in EIM, you search for all tritium concentrations from monitoring wells for the past ten years. EIM sends the results to a table as shown in Figure 1.

Tabular view of Tritium query results in Locus EIM

Figure 1 Tabular view of Tritium query results

The table has 717 results for multiple wells. It is very difficult to see overall patterns here, either spatially or temporally. Each of the 717 results is one item, and if you try to scroll and sort the table to see if tritium is increasing or decreasing over time, your working memory is quickly overwhelmed. This is where a good data visualization can help.

To start, you decide to send the data to the Locus GIS+ application, using the graduated color and size options. The GIS+ takes the concentrations from the results table and plots them on a site map using the stored coordinates for each well, as shown in Figure 2. The map represents each location with a symbol that is colored and sized to reflect the actual maximum value at that location. The map legend shows you how this was done. Large red circles, for example, represent results from 4,500 to 7,000 pCi/L. As the sizes get smaller, and the colors go from red to blue, the actual result gets smaller.

Graduated symbol and color map in Locus EIM

Figure 2 Graduated symbol and color map of tritium concentrations

This map is great for showing spatial patterns in the data. You can easily pick out a couple of “areas of concern” near the center of the map – one with orange and yellow circles, and another with red circles. To revisit our discussion on working memory and chunks, the map takes the 717 results and summarizes them so your brain can quickly pick out the two areas of concern.

Let’s look more closely at the area of concern with higher results. If we zoom in on the map, we see the two red locations are wells MCOI-5 and MCOI-6 as shown in Figure 2.

Figure 3 Zoomed map for one area of concern

The map shows you where these two high concentrations of tritium are located. But what if you want to see how the concentrations vary over time? You can make a time series chart in EIM for these wells and include a desired regulatory limit, as shown in Figure 4. The green and blue lines represent the tritium concentrations over time for the two wells. The red line at top shows a regulatory action limit.

Line chart in Locus EIM

Figure 4 Line chart showing time series for tritium for two wells, with action limit

The chart shows you two important things. First, and most importantly, all the tritium concentrations for both wells lie well below the regulatory action limit! Second, the concentrations have very different trends for the two wells: MCOI-6 started higher but has trended lower, while MCOI-5 started below MCOI-6 but has now surpassed it. You can confirm these general impressions by running concentration regression charts in EIM for the two locations, as shown in Figure 5. The charts show the best fit regression line and the strength of the relation.

Figure 5 Concentration regression charts in EIM

You can grasp these facts quickly because the of how the chart works. Each series of concentrations for a well consists of multiple data items that are ‘chunked’ into one line on the chart. There are two many individual data points on this chart for your working memory, but only three lines, which can easily be manipulated in your brain. For comparison, Figure 6 shows the actual data values for the chart. The time trends shown above in the charts are not as obvious from the table.

Data values in Locus EIM

Figure 6 Actual data values for the chart in Figure 4

Now, this might be counter-intuitive, but what if you wanted to put some of these values on the map? While visualizations do help understand data, sometimes it can be useful to have the data shown as well so viewers can see where the visualizations came from. The EIM Data Callouts function can do this. Figure 7 shows data callouts for the two wells. Each callout shows the maximum annual tritium result for 2010-2020. Now you have the actual tritium concentrations located spatially next to the matching wells!

Data callouts in Locus GIS+

Figure 7 Data Callouts in EIM GIS+

Now that you know where your tritium might be a concern, suppose you want to see what’s going on with groundwater at your site. The EIM contouring module does that for you. There are multiple contouring options, but for this example let’s use the default options for kriging. We know from Figure 2 that the wells MCOI-5 and MCOI-6 are located in the Mortandad Canyon. Figure 8 shows the contouring map generated from EIM for the groundwater wells in that canyon, using the most recent groundwater levels. Higher groundwater values are lighter in color than lower values.

The area of concern is marked with an arrow at upper left. The contour lines and values can help you determine how the tritium might migrate in your site. Imagine trying to picture this just using tables of groundwater readings! With the contour map, the readings turn into lines that can be chunked together for analysis: the higher levels at the upper left forming a “plateau”, the closely packed lines moving across the map to the east, and then the “saddle” area at lower right. These different line patterns carry particular meanings to engineers and scientists who interpret contour maps.

Figure 8 Contour map for groundwater levels

The contour map completes our tour of some of the visualization tools in EIM. Because visualizations let you chunk items together, you can look at the ‘big picture” and not get lost in tables of data results. Your working memory stays within its capacity, your analysis of the information becomes more efficient, and you can gain new insights into your data.

An EHS&S Look Into the Tech Used in the Iowa Caucuses

The Importance of User Implementation and Quality Assurance from an EHS&S Software Provider

After reading about the IowaReporterApp used during the 2020 Iowa caucuses, it struck me how remarkably similar it is in intended function to the EHS&S software developed by my employer, Locus Technologies. Both their application and Locus’ mobile technology collect large quantities of sensitive data from several remote users at multiple facilities, allowing for instant calculation and reporting. What surprised me though, is just how vastly different their user implementation and data management methodology was from what is standard operating procedure at Locus.

In this blog, I will highlight some of the pitfalls of the IowaReporterApp, and compare it to Locus’ EHS&S software. Note, this article is not a political critique, but is an examination of data collection and data quality methods used during the caucuses.

Complex data - Data stewardship

Implementation

Users were introduced to the IowaReporterApp just days before the caucuses and received no app-specific training. Many users were downloading the application on the night of the caucuses.

The Iowa caucuses have been held biennially for almost a half-century as the first major contest of the primaries. The date of the caucuses was a surprise to no one. As a result, app development deadlines should have given enough time for user implementation, through one-on-one training or presentations with appropriate support staff. If app deadlines were not met, there should have been a fallback to redundant reporting systems, like in the case of Nevada, who were also planning to use the app but have opted out after the debacle in Iowa.

When Locus introduces new users to our software, we take implementation seriously. Our customer support team is composed of domain experts who have actively built and used Locus software. We know the deadlines and the problems users typically face during the implementation process. From one-on-one and on-site training to quick turnaround, our support team does everything they can to ensure that users are comfortable with our product as soon as possible.

Complex data - Software quality assurance

Untested Software/Quality Assurance

User implementation deadlines are all the more important given that the software had no real-world use to this point. While it is not advisable to go live with untested software, at the very least, having users stress test a product before field-use could have staved off a few issues.

This is something we see frequently with newer products and newer companies. Locus has over 20 years of experience creating EHS&S software used by U.S. government organizations and Fortune 500 companies. Our quality assurance team rigorously tests any update we bring to customers and doesn’t rush changes to sell a platform update, since every user is always on the same version of Locus software.

Complex data - Data redundancy

Data Redundancy

No one can question that Excel or Google Spreadsheets can perform math correctly, but what is frequently overlooked or not even considered, are the macros, custom functions, and calculations that are often added to spreadsheets when deployed for managing data and other tasks. If one fails, there need to be backups for reporting and storing data.

When the untested application predictably failed, users flocked to the phone lines as a redundancy. Manual data collection on such a scale created confusion and could not carry the load, and had no way of accounting for errors in data entry. At Locus, we understand the importance of EHS&S data, and maintain backups and full audit trails for all critical data, with quick restoration available so you can keep going if anything should happen.

Complex data - Security

Security

The IowaReporterApp was not released in time to get approval in Apple’s app store, and it was sent out through beta testing platforms which required suspension of smartphone security settings.

ProPublica, a nonprofit organization who produces public interest investigative journalism, did a report on the security of the IowaReporterApp after the Iowa Caucuses. Shockingly, they found security problems to be “elementary” and that the app was so insecure that vote totals, passwords, and other sensitive information could have been intercepted or changed. Luckily, there seems to be no evidence of hacking or tampering with results.

Locus understands the need for security with sensitive data, and hosts our entire infrastructure in the most secure and reliable cloud, Amazon Web Services. AWS has an unmatched portfolio of cloud services that Locus fully utilizes to the benefit of their customers.

Complex data - Data entry

Summary

Overall, I think that the mishaps related to the IowaReporterApp show just how easy it is for a data collection and management application to fail if not properly implemented and ran by those with years of practical expertise. Subverted data quality will always be extremely costly to your organization, both financially and otherwise, and should be avoided unequivocally.

Locus Technologies receives prestigious EBJ Award for 14 consecutive years

Environmental Business Journal (EBJ) recognized the firm for growth and innovation in the field of Information Technology

MOUNTAIN VIEW, Calif., 10 February 2020

Locus Technologies, leading provider of environmental management and EHS software, was awarded a 14th consecutive award from Environmental Business Journal (EBJ) for growth and innovation in the field of Information Technology.

EBJ is a business research publication providing strategic business intelligence to the environmental industry. Locus received the 2019 EBJ Award for Information Technology by expanding their software and services.

Among the key drivers for Locus in 2019 was the growth of key software applications for waste and sustainability, as well as the introduction of their facilities management app. Locus software also now further integrates with EPA compliance systems like CMDP, eManifest, and eGGRT. Finally, in terms of services, Locus achieved over 500 GHG verifications under the California AB32 program, being the first company to do so. They were also among the first independent bodies to become certified for the new California Low Carbon Fuel Standard verification.

“We would like to express our gratitude for receiving the EBJ Information Technology award for another year. We look forward to providing our customers with cutting-edge software and services as we seek to improve in the areas of artificial intelligence, IoT integration, and blockchain technology,” said Wes Hawthorne, President of Locus Technologies.

How to extend your EHS software with integrated systems

Integration with other systems, whether on-premises or in the cloud, has become a key wishlist item for many EHS software buyers. It allows you to take advantage of other tools used by your organization (or available from third parties) to simplify processes, access information, and enhance communication, both internally and externally.

Locus Technologies obtains accreditation as verification body for Low Carbon Fuel Standard (LCFS)

Locus staff continue to prove expertise in this emerging compliance area with accredited staff throughout California and the Midwest. 

MOUNTAIN VIEW, Calif., 27 January 2020
Locus Technologies, (Locus), industry leader in water quality, EHS, sustainability, and compliance management software, is pleased to announce they are among the first accredited verification bodies for the Low Carbon Fuel Standard (LCFS) program administered by the California Air Resources Board (CARB). Locus verifiers were accredited for fuel pathway applications, alternative fuel transactions, and petroleum-based fuel reports.

Originally adopted in 2009, the goal of the LCFS program is to reduce the carbon intensity (CI) of the transportation fuel pool. The LCFS is one of the key AB 32 measures to reduce greenhouse gas emissions in California, while reducing petroleum dependency and achieving improved air quality. The program has grown in scope, and certified third-party verifiers can now review both applications and routine reporting.

Locus Technologies has been a certified third-party reviewer of GHG verifications for CARB since 2010 under the Mandatory Reporting Rule and maintains an unmatched track record. Not one of over 500 GHG verifications by Locus has been overturned, a standard the company intends to match with LCFS reporting.

Locus has staff and expertise to review Tier 1 fuel pathway applications and annual reports under LCFS as well as other LCFS projects, with verifiers located in San Francisco, San Jose, Sacramento, Los Angeles, and in the Midwest. Locus also offers software products designed to assist reporters in complying with the LCFS program.

From configurable smart notifications to follow-up assignments when accidents, near misses, or when other incidents are logged, Locus EHS&S compliance software offers assurance that your safety procedures can be followed promptly and correctly.

 

 

Top 10 Enhancements to Locus Environmental Software in 2019

Let’s look back on the most exciting new features and changes made in EIM, Locus’ environmental data management software, during 2019!

1. Migration to AWS Cloud

In August, Locus migrated EIM into the Amazon Web Services (AWS) cloud. EIM already had superior security, reliability, and performance in the Locus Cloud. The move to AWS improves on those metrics and allows Locus to leverage AWS specific tools that handle big data, blockchain, machine learning, and data analytics. Furthermore, AWS is scalable, which means EIM can better handle demand during peak usage periods. The move to AWS helps ensure that EIM remains the world’s leading water quality management software.

2. SSO Login

EIM now supports Single Sign-On (SSO), allowing users to access EIM using their corporate authentication provider. SSO is a popular security mechanism for many corporations. With SSO, one single login allows access to multiple applications, which simplifies username and password management and reduces the number of potential targets for malicious hacking of user credentials. Using SSO with EIM requires a one-time configuration to allow EIM to communicate with a customer’s SSO provider.

Locus Single Sign On (SSO)

3. GIS+ Data Callouts

The Locus GIS+ solution now supports creating data callouts, which are location-specific crosstab reports listing analytical, groundwater, or field readings. A user first creates a data callout template using a drag-and-drop interface in the EIM enhanced formatted reports module. The template can include rules to control data formatting (for example, action limit exceedances can be shown in red text). When the user runs the template for a specific set of locations, EIM displays the callouts in the GIS+ as a set of draggable boxes. The user can finalize the callouts in the GIS+ print view and then send the resulting map to a printer or export the map to a PDF file.

Locus GIS+ Data Callouts

4. EIM One

For customers who don’t require the full EIM package, Locus now offers EIM One, which gives the ability to customize EIM functionality. Every EIM One purchase comes with EIM core features: locations and samples; analytical and field results; EDD loading; basic data views; and action limit exceedance reports. The customer can then purchase add-on packages to get just the functionality desired–for example a customer with DMR requirements may purchase the Subsurface and Regulatory Reporting packages. EIM One provides customers with a range of pricing options to get the perfect fit for their data management needs.

EIM One Packages

5. IoT data support

EIM can now be configured to accept data from IoT (internet of things) streaming devices. Locus must do a one-time connection between EIM and the customer’s IoT streaming application; the customer can then use EIM to define the devices and data fields to capture. EIM can accept data from multiple devices every second. Once the data values are in EIM, they can be exported using the Expert Query tool. From there, values can be shown on the GIS+ map if desired. The GIS+ Time Slider automation feature has also been updated to handle IoT data by allowing the time slider to use hours, minutes, and seconds as the time intervals.

Locus IoT Data

6. CIWQS and NCDEQ exports

EIM currently supports several dozen regulatory agency export formats. In 2019, Locus added two more exports for CIWQS (California Integrated Water Quality System Project) and the NCDEQ (North Carolina Department of Environmental Quality). Locus continues to add more formats so customers can meet their reporting requirements.

CIWQS and NCDEQ Exports

7. Improved Water Utility reporting

EIM is the world’s leading water quality management software, and has been used since 1999 by many Fortune 500 companies, water utilities, and the US Government. Locus added two key reports to EIM for Water in 2019 to further support water quality reporting. The first new report returns chlorine averages, ranges, and counts. The second new report supports the US EPA’s Lead and Copper rule and includes a charting option. Locus will continue to enhance EIM for Water by releasing the 2019 updates for the Consumer Confidence Report in January 2020.

Locus Water Utility Reporting

8. Improved Non-Analytical Views

Locus continues to upgrade and improve the EIM user interface and user experience. The most noticeable change in 2019 was the overhaul of the Non-analytical Views pages in EIM, which support data exports for locations, samples, field readings, groundwater levels, and subsurface information. Roughly 25 separate pages were combined into one page that supports all these data views. Users are directed through a series of filter selections that culminate in a grid of results. The new page improves usability and provides one centralized place for these data reports. Locus plans to upgrade the Analytical Views in the same way in 2020.

Non-analytical views in Locus EIM

9. EIM search box

To help customers find the correct EIM menu function, Locus added a search box at the top right of EIM. The search box returns any menu items that match the user’s entered search term. In 2020, Locus will expand this search box to return matching help file documents and EDD error help, as well as searches for synonyms of menu items.

Locus EIM Quick Search

10. Historical data reporting in EDD loading

The EIM EDD loader now has a new “View history” option for viewing previously loaded data for the locations and parameters in the EDD. This function lets users put data in the EDD holding table into proper historical context. Users can check for any unexpected increases in parameter concentrations as well as new maximum values for a given location and parameter.

California’s Low Carbon Fuel Standard Program

Last week Locus attended the first training session offered by California Air Resources Board (CARB) for verifiers under the California Low Carbon Fuel Standard (LCFS) program. The California LCFS program has been ramping up over the past several years, and is now ready to start certifying third-party verifiers to review both applications and routine reporting.

The LCFS program is part of California’s initiative to meet the AB32 requirements of reducing overall greenhouse gas emissions to 1990 levels by 2020, and 40% lower than that level by 2030. LCFS is specifically intended to address emissions from transportation fuels in California, which are approximately half of the overall emissions statewide. Like the Greenhouse Gas Mandatory Reporting Rule and Cap-and-Trade programs that preceded it, the California LCFS program uses a market-based approach to incentivize innovation and new approaches to reduce emissions.

The program covers a wide variety of projects, including production of alternative fuels (e.g. renewable diesel and biogenic compressed natural gas), innovative approaches to fossil fuel production and refining, and direct carbon capture and sequestration. Fuels are assigned a carbon intensity based on overall carbon dioxide emissions over the entire life cycle, from production to processing to shipping to consumption. The carbon intensity is essentially a measure of the emissions from the fuel per unit of energy. The lower the carbon intensity value, the less impact the fuel has in terms of carbon emissions. Certain fuels can even have a negative carbon intensity, which essentially means the fuel production process is absorbing more carbon than is eventually emitted to the atmosphere (such is the case for compressed or liquefied natural gas produced using biomethane from manure collection). The program also has impacts well outside the California border. After all, fuel that is eventually used in California can originate anywhere in the world, and the LCFS program allows for these projects to obtain credits regardless of their location.

Unsurprisingly, California was the first state to adopt and implement a LCFS program, and the first to establish a third-party verification program specific for LCFS. Although it was clearly the first presentation of this training material, staff from CARB as well as the Climate Action Reserve and The Climate Registry were on hand to assist in addressing questions and topics that weren’t covered in the prepared materials. And considering the wide variety of LCFS project types and the disparate backgrounds of attendees for the verification training, they did a great job of getting everyone all the information they needed to understand and verify these projects.

For those participating in the LCFS program or considering projects under the program, there are a few key things to keep in mind.

First and foremost, like any market-based emission program that includes a verification or auditing requirement, transparency is critical. The verifiers are trained to dig deep into your data, and not to take ‘no’ for an answer. Be prepared to have your metadata and documentation assembled and easily made available to the verifier. (For more on Transparency in Reporting, view this webinar)

Second, the LCFS program includes requirements for continuous or near-continuous monitoring for many parameters, and instrumentation capable of electronic data archival. Manual data records and transcription are still acceptable under other carbon offset programs, but under LCFS these options are no longer allowed. Be sure that your instrumentation is consistent with the specific LCFS requirements, or you’ll be seeing a non-conformance from your verifier.

There were many other tips and common pitfalls highlighted during the training for specific LCFS project types. Overall, I’m very excited to see how the LCFS program evolves in California, and how the energy industry takes advantage of these incentives to provide new options for transportation fuels that will reduce carbon emissions.

Update: Locus is now an approved verification body for the Low Carbon Fuel Standard. Learn more here.
