Underground Utility Location For Safer Construction

In the February 2026 FOA Newsletter we talked about locating underground utilities to ensure safe construction. In that article, we described the process of location and how the location of underground utilities are marked. In the second part of this article, we discuss the tools and techniques for locating underground utilities.

Many contractors know that even if location has been done and locations market, they need to double check before digging or boring around existing infrastructure. This article will discuss how locating is done and what techniques should be used in different circumstances.

Also below is how Texas811, the "Call Before You Dig" organization in Texas is using existing fiber optic cables to help prevent dig-ups.

Part 2 -  Underground Location Techniques

When we first started researching underground location techniques, we ran into a rather unexpected reference to "dowsing." Dowsing is a technique where a person - the dowser - uses a "Y" shaped stick or other implement to locate things underground. The technique has been documented for 500 years or more and is reputed to be quite effective at finding water and minerals. But few locators use dowsing for locating underground utilities before digging; they use more modern techniques. (For more information on dowsing, we recommend Icy Sedgwicks article "The Folklore of Dowsing, aka Water Witching from which this photo comes.)

dowsing


Today two more modern technologies dominate the industry: Electromagnetic (EM) and Ground Penetrating Radar (GPR)

Electromagnetic (EM) Locators

Underground location

EM pipeline and cable locators are essential tools for locating underground utilities like pipelines, power lines, and communication cables. They operate by identifying electromagnetic fields associated with these utilities. In most cases, this involves sending a radiofrequency signal down the pipeline or cable. If the cable or pipeline is not metal, there needs to be a metal wire, known as tracer wire, buried above or beside the pipeline or cable in order for an EM locator to find it. Some communications cables will have a metal sheath to protect the cable or a metal strength member which can also transmit the radiofrequency. Details on tracer wire are covered after the EM locator section.

1. Passive EM Locators: These devices detect natural electromagnetic fields emitted by live utilities, such as power lines. They are useful for quick scans, but may not detect inactive or non-conductive utilities.

2. Active EM Locators: Active locators apply a specific frequency signal to a utility line using a transmitter. The receiver then detects this signal, allowing for precise tracing of the utility's path.

Tracer wire is simply an insulated wire (conductor) that is buried in the same trench as a non-metallic pipe, conduit, or cable. When the utility needs to be found, a locator transmitter is clipped to the wire and to a remote ground stake; the alternating current that flows along the wire sets up an electromagnetic field that an EM locator can trace from the surface. Tracer wire became a federal requirement for new plastic natural gas mains and service lines in 1996. Beginning in 2014, some states began requiring that all underground facilities be “electronically locatable,” and other states required tracer wire for non-metallic water and/or sewer lines.

A few of the technical issues a locator faces and needs to learn about include:
  • Signals jumping from one cable or pipe to another in crowded rights-of-way.
  • Different soil conditions.
  • Non-metallic pipelines and cables without tracer wire.
  • Broken tracer wire.
  • Distortion and its effects on locate accuracy.
  • Finding the correct signal when others exist on the site.


A new electromagnetic location technology involves burying RFID markers like those used to identify products. The locator can read the RFID tags and not only locate the buried utility but read the identification information about the utility. To learn more, see the new product reviewed in the Technical section below.


Ground Penetrating Radar (GPR)

Underground location by ground penetrating radar

GPR works like aerial radar but underground, locating using radio waves. GPR equipment is used in a wide variety of industries, but in the damage prevention industry, its most common use is locating non-metallic pipelines without tracer wire and cable without a metal sheath. As the locator pushes a cart (like a lawn mower) across the ground, a radar antenna sends waves into the ground. When those waves hit something different, like a pipe or any subsurface structure, they bounce back. A computer on the GPR cart shows that bounce as a shape or line on a screen. A trained technician can look at these images and be fairly certain if it is showing a pipeline, cable, duct, or anything else that should be marked as a part of the location.

These are some situations where GPR works well:
  • Dry, sandy, well-drained soils like deserts (Arizona, New Mexico, etc), sandy areas, and power line corridors.
  • Loose gravel or crushed stone backfill, like recently built subdivisions, utility corridors, railroad rights-of-way.
  • Dry or moderately dry silts/loams.
  • Pavement

GPR does not work as well in these conditions:
  • Wet clay and silty clay loams
  • Salt-contaminated or tidal soils like coastal marshes.
  • Very wet, fine sand
  • Rebar-dense or fibre-reinforced concrete



"Potholing" or Vacuum Excavation is a vital part of locating
It is common practice to use vacuum excavation or
digging small test holes by hand for verifying the location of buried cables and pipelines. This process is called “potholing” or “daylighting.” The name potholing comes from the fact that the process creates a round hole, six inches to a foot in diameter, in the ground all the way down to the location of the pipeline or cable. Daylighting comes from the fact that the hole puts daylight on the pipeline or cable. There are many circumstances where potholing or daylighting is critical and often mandatory.

Potholing can be the best form of excavation when only a small area needs to be excavated, like:
  • Fence post installation
  • Utility pole installation
  • Sign post installation

Vacuum excavation can be done using either water or air to create the hole.


Certifications For Locators
There are no mandatory certifications or training required for the workers who act as locators, but the National Utility Locating Contractors Association (Nulca), a national organization representing utility locating professionals, published its first Competency Standard for training utility locators in 1996. This guideline has become an industry guide and is now in its fifth revision. In 2016, Nulca rolled out its accreditation/certification program. This program is voluntary, but it does create a standard for training. There are other training certification programs in Canada, Australia, New Zealand, the UK, as well as Staking University in the U.S., but the NULCA program has the momentum of the industry’s largest locator organization behind it.

Texas811 Launches First-of-its-Kind Technology to Help Prevent Underground Utility Strikes

Distributed fiber-optic sensing turns existing fiber-optic cables into real-time monitoring systems

Texas811, the nonprofit organization that manages the state's "call before you dig" system, today announced the launch of Texas811 Guardian. The innovative technology uses distributed fiber-optic sensing to turn existing fiber-optic cables into real-time monitoring systems that detect excavation activity, preventing damage before it occurs.

distributed sensing system

"On an annual basis, underground utility strikes endanger thousands of lives, cause billions of dollars in damage, and disrupt services," said Kyle VanLandingham, director of business development at Texas811. "Research shows that a quarter of all damages occur because the Texas811 system is not used, and three-quarters of those damages result from professional excavators who know the rules but do not follow them."

The patent-pending Guardian program integrates fiber-optic sensing alerts for excavations directly into the active Texas811 ticket database to identify issues requiring urgent attention. When an excavation is detected, an alert is sent to Texas811, and Guardian immediately queries the system to check for an active 811 ticket. If "yes," the system remains silent; if "no," Guardian's technology flags it and promptly notifies utility operators of an unauthorized excavation that could pose a significant threat, providing the exact location and the excavation type (mechanical or manual) so they can deploy the proper resources to protect their underground lines.

"Because Texas produces more than 10% of all 811 tickets nationwide, we believe Guardian has the potential to influence the national standards for damage prevention," said Arron Mitchell, chief innovation officer for Texas811. "Our long-term vision is to create a nationwide network of real-time excavation monitoring, setting a new benchmark for safety and reliability across America's infrastructure."

Small Towns, Big Speeds: How Some Municipal Broadband Providers Outperform Their ISP Peers

Speedtest of muni ISPs

Ookla, the Speedtest company, studied the performance of 14 of the largest municipal networks and compared their performance to each other and to their ISP competitors. Using Ookla’s Speedtest Intelligence® data, they studied the performance of 14 of the largest municipal networks from December 2024 through December 2025, and compared their performance against each other and to their ISP competitors in their market. It’s important to note that some Speedtest data may reflect the speeds of the users’ broadband price plans vs. the  possible speeds that the provider can deliver.

Ookla selected these 14 municipal providers because they are some of the largest in the U.S. based upon reported subscriber numbers  and because they had the most test samples from these providers. Notably, EPB in Chattanooga, Tennessee, which is the largest municipal broadband provider in the U.S.,  did not have any competitors with enough test samples to compare its performance too.

Key Takeaways:

When compared to their broadband competitors, eight municipal providers in the U.S. that we monitored using Ookla Speedtest data beat their broadband competitors in median upload speeds and one municipal provider,
  • Sherwood Broadband, outpaced the competition in median download speeds. We monitored a total of 14 municipal providers, however, one provider —EBP— did not have any competitors with enough test samples to compare its performance against.
  • Fort Collins, Colorado’s Connexion was the leader in median upload speed, delivering an average median upload speed of more than 300 Mbps for the entire 13-month period from December 2024 to December 2025.
  • Sherwood Broadband in Sherwood, Oregon, was the top provider in median download speeds, delivering an average median download speed that surpassed 400 Mbps eight months out of a 13-month period from December 2024 to December 2025.
  • UTOPIA Fiber in Utah is a standout in latency, delivering the lowest latency of all 14 municipal broadband providers with a multi-server latency consistently in the low 6 milliseconds (ms) to 8 ms range.

More than 700 communities across the U.S. are served by some type of municipal broadband network that provides its residents with internet services. In simple terms, a municipal broadband network is an Internet service provider (ISP) that is owned and operated by the local city or county government or a municipal utility rather than a private company like Comcast or AT&T.

Governor Newsom turns on largest public broadband network, California connects first rural community to internet


California middle mile network connects first users

While most articles focus on fiber to the home or alternatives to connect users, no ISP can provide connections without a reliable middle mile network. In rural areas, good connections to the Internet are rare. Recognizing this problem, California passed legislation in 2021 to create an open-access middle-mile network to bring equitable high-speed broadband service to all Californians.  SB 156 provides $3.25 billion to build the necessary Middle Mile infrastructure to bring internet connectivity to homes, businesses and community institutions. The design and construction of the middle-mile network is monitored by the Middle-Mile Advisory Committee (MMAC).

The Bishop Paiute Tribe is now the first customer of California’s Middle-Mile Broadband Network (MMBN), bringing high-speed, reliable internet to a rural and historically underserved community. Students were among the first to log on — experiencing dramatically faster speeds and new access to education, health care, and opportunity.

CA middle mile project

As a tribally-owned internet service provider, the Bishop Paiute Tribe will independently manage and operate its broadband service, including setting pricing and service offerings for households on and off the reservation.

A model for government-to-government relations, the groundbreaking partnership with the Tribe reflects California’s commitment to tribal sovereignty and self-determination.

As the network continues to attract internet service providers, thousands of residents along the Eastern Sierra Nevada and millions more across the state will gain access to more options for reliable and affordable high-speed internet service.

California continues to make progress delivering over 8,000 miles of open-access broadband fiber, enabling more affordable and reliable broadband access for many of California’s most underserved communities.

Alternatives For Installation of Optical Cables in Urban Areas

Vladimir Grozdanovic

The deployment of optical networks in urban environments can be highly challenging. Aerial construction is often not permitted, and in some areas of a city there may not even be utility poles available for use. Underground construction may also be prohibited  or become highly complex due to the high density of existing underground infrastructure (power networks, gas pipelines, water supply systems, telecommunications ducts, etc.). An additional challenge is that existing documentation of underground infrastructure is often not fully reliable or up to date.

Cities may facilitate the development of new networks by utilizing existing capacities of telecommunications operators. One option is the lease of a certain number of dark fibers in existing cables between required locations. It is also possible to use available empty ducts, enabling the installation of new smaller-diameter ducts or the installation of new cables to the desired destinations. This approach can significantly save time and often reduce costs. However, all of the above requires prior verification of the availability of existing telecommunications duct infrastructure.

The question arises: what should be done when new excavation in urban areas is not permitted, and when existing telecommunications operators’ capacities are either fully utilized or not available in the areas of interest? Have you considered using robots to install cables in sewers?

How Do You Connect Or Test Multicore Fiber?

Our discussion about the number of manufacturers offering multicore fiber (MCF) at OFC this year raised the usual questions, how to connect to MCF and how to test it. For answers, we contacted Chiral Photonicss which ahs been making several versions of MCF for more than a decade now. They also make what you need for connections and test, MCF to single fiber fanouts.

Multicore Fiber Fanout

MCF breakouts
MCF fanout and variations from Chiral Photonics

While connectors and transceivers for 4 fiber MCF were shown at OFC, fanouts are needed for testing and probably inside transceivers. Thus each core can be connected or tested separately in much the same way as multifiber connectors like MPOs have been handled until the recent introduction of dedicated test sets.

For more information on MCFs and fanouts, here is the Chiral Photonics website.

A Quiet But Important Change In The Fiber Optic Cable You Buy

With so many cable designs today, like microcables or high fiber count cables, requiring bend-insensitive fibers, would it make sense to make all or most singlemode fibers as bend insensitive fiber?

Two manufacturers (Corning and OFS) told FOA the industry is moving towards a G.657.A  specification in fiber, because the industry is moving towards smaller denser cables in the network & the bend resilience is a requirement for the cable design.  So singlemode fiber is moving to being BI fiber, exactly what happened with 50/125 laser optimized fibers a decade ago. With most new fiber, compatibility is not an issue. But it is recommended to check with the cable manufacturer if you are not sure what fiber is being used in the cable you are purchasing.

entire FOA report on compatibility of G.652 and G.657 singlemode fiber that includes this summary.

Learning Important Information From A Found Cable Scrap

While walking down the street near the FOA office, we found this cable laying in the gutter. What a find! A short length of Corning Rocket Ribbon 864 fiber cable left over from an installation by a contractor.

Corning RR Cable

We brought the cable back to our office with the intention of opening it up and creating a video about the construction of this modern high fiber count cable, but something got our attention first. The cable had a very long line of printing on it with lots of interesting and useful information. So before we started deconstructing it, we decided to photograph the printed information and interpret it. That turned out to be an important part of the information we learned from the cable. Then, as you will see below, we dissected the cable and learned even more.

Red more about what this cable marking tells you and what the cable looks like when you open it up to prepare for splicing.

Tech Questions/Comments From FOA Newsletter Readers 

More Q&A in the FOA FAQs Page  

How Long Do Fiber Optic Cables Last?
Q: I work at a large industrial facility with several buildings connected by fiber optic cables. The fiber cables run through underground conduits between the buildings. Many of the fiber cables were installed 20 to 25 years ago. Is there any general industry guidance on when cables such as ours should be replaced solely based on the age of the cable?
A: The question you ask is one often asked. Usually it refers to the outside plant cables that have been used for many years - some now approaching 40 years like the optical power ground wire (OPGW) used by electrical utilities and some telco cables installed in the same era. Cable manufacturers are not very specific about cable lifetimes, but the standard today is cables are designed to last 40 years or more. Cable installed 20-25 years ago should be still serviceable for years to come. Some cables may suffer from moisture migration which can cause attenuation increases and fiber brittleness. Brittleness is generally not a problem is the fibers are undisturbed but it is a good reason to not disturb them. Most cable plants are not replaced unless they suffer damage - weather and wildfires are a big problem for serial cables, flooding and freezing for underground cables - or the owner is ready to upgrade communications systems and needs more modern, higher performance fibers.
Our advice would be to not disturb the cables you have if systems are working properly. If you are in a “nonstop” environment that would be badly harmed by loss of communications and you want to have a backup, you could hedge your bets and install ducts for replacement. cables. If there is space in the ducts, you can install microducts or fabric ducts in the same conduits and install backup cables. You may read advice that says cables need maintenance like cleaning connectors and testing periodically. That’s bad advice; it’s more likely to damage the cables. Our advice on cables is install them, lock them up and don’t worry. But have a restoration plan. Have documentation on the cables, spares and be prepared to repair or replace them quickly. See https://foa.org/tech/ref/restoration/rest.html

Hybrid cable For Aerial Installation
Q: Is there a hybrid cable (fiber + conductors (2 or 4)) that can be aerial lashed?
A: Practically any outside plant cable can be installed aerial if it is within the weight limits of the messenger being used. Cables with fiber and copper conductors are used for connections to remote electronics or cameras.

Gloves for Splicing?
Q:
What’s the FOA’s (or your personal) stance on wearing gloves whilst splicing?

A: Wearing gloves may recommended for preparing metallic armored cables because of the danger of cuts. For regular cables, gloves may be recommended for those who use knives to open cables, a practice still used. However for splicing fibers where some recommend them to prevent sticking yourself with fibers, it hampers fiber handling and slows the work down. We do not recommend gloves except for prepping certain types of cables.

Are Splices Too Close Together A Problem?
Q:
When installing fiber in an plant. Is there a minimum distance that two splices should be apart? ;
A: The recommendation in the past was to bot have splices close together since slight reflectances at the splices could cause an interference problem with laser systems. The recommendation was to keep splices 30-100m apart. IT was especially noted if you had to splice in a section of cable to repair a cable break. However we have not heard this in recent history, perhaps because fusion splices are so good. We asked a number of FOA's technical advisors for their opinions. Their feedback is the problem of reflectance causing problems at closely spaced splices seems to have disappeared. It’s a matter of better splicing machines and more consistent fibers, and also a matter of lasers being engineered to work better in links.

Copper Tech Wants To Learn Fiber Optics
Q: I am originally from copper installations and faults finding. I would like to get involved in Optic fibre faults and finding, how do I go if there is a possible training it will be highly appreciated,
A: Just learn about fiber, especially fiber testing and troubleshooting. Fiber U has courses you can take for free.

OSP Installation Standards
Q: I'm looking for standards for fiber optic OSP installation.
A: The whole issue of OSP standards has been one FOA been trying to get standards bodies interested in for years with little success, probably because it is an enormous project. Right now there are two documents that address OSP cable plant:

ITU-T    Technical Report, TR-OFCS Optical fibres, cables and systems, (3 July 2015)
As you can see, the ITU document is almost 10 years old and a lot has changed in that time.

The Other is the Telcordia Blue Book - Expensive but thorough
Telcordia Blue Book - Manual of Construction Procedures
Document Number SR-1421, Issue Number 07, Issue Date Jan 2023

Is The FOA CFOT® A License?
Q:
Can you use a CFOT certification to install fiber and charge for it? Or do you need other licenses as well? ;
A:
FOA Certification is considered evidence of competence and accepted worldwide by many companies, groups, etc. Licenses are a legal credential required by local authorities to conduct business for anything from a barber to a truck triver to contractors doing fiber or other work. Most locales require a license as a contractor which may require a fiber specialty. You need to investigate this with your local authorities.

Updating FOA Courses And Reference Materials
Q: How often are FOA courses updated? And when they get updated, what happens to those who would have done a previous version?
A: The FOA certifications are updated as needed to stay current with technology and applications. Updates are incremental and we do not require current certification holders to retake courses or exams. 

Past questions can be found on the FAQs page.


Fiber Optic Color Codes Reference Chart
Q: Has anyone made a fiber optic pocket reference chart that has cable color orders, frequencies, or other commonly used info on it?
A: The FOA has a page on its Online Guide that covers color codes (https://foa.org/tech/ColCodes.htm). It is the most popular page in the FOA Guide! It works great with a smartphone.

The Types of Work Done By Fiber Techs And How It Affects Training

FOA install banner

 What is a fiber optic technician? What kinds of work do they do? Those topics were the center of FOA discussions with the US Department of Labor Bureau of Labor Statistics that led to the new job category of "Telecommunications Technician" on the BLS website. The focus of this job category is primarily the installation and operation of the fiber optic cable plant, but one should not forget the cable plant must be designed also as part of a more extensive communications network.

In our discussion with the BLS analysts, we pointed out the various stages of a fiber optic communications network project and how techs with various knowledge and skill sets are needed and involved in every step. This web page on the fiber optic workforce describes how FOA defines these stages of a project and the skills of the techs needed. This is not unique to FOA; it's what has been traditional at telecom companies forever.



FOA Schools

  FOA's roster of approved schools continues to grow as more organizations recognize our expertise in workforce development and our comprehensive support for getting new schools started. FOA has over 25 years experience and over 100,000 certified fiber techs (with ~140,000 certifications). As a non-profit organization founded by the industry specifically to develop a competent workforce, FOA provides the consultation, curriculum and contacts to get schools started as a free service to new schools.

What Fiber Techs Don't Know -

These are some of the topics that we have noticed are answered incorrectly more often in FOA and Fiber U tests.

Most of the questions missed are on testing.

1. OTDRs - particularly what information is in the OTDR trace.

2. The difference between dB and dBm

3. Loss budgets - both the concepts and doing the math

4. Insertion loss testing - single-ended or double ended for testing patchcords or cable plants, how to set 0dB references

5. Units of measure - fiber is measured in microns, wavelengths in nanometers, etc.

At FOA, we're working to add Fiber U MiniCourses on these topics and working with our schools to emphasize these topics in their classes.

If you are going to be taking a FOA certification course or test in the near future, these topics should be on your final exam study list.

What We Learn From Hands On Labs
We learn about students performance in hands-on labs from the feedback of our instructors and our own experiences too. One big problem is the use of hand tools. Growing up today, you learn how to use keyboards, mouses and touch screens, but decades ago, you also learned how to use basic hand tools. This is big enough of a problem that we're considering adding some video lessons on basic hand tools to prepare students for cable prep, termination and splicing that require the use of hand tools.

fiberu.org

FOA offers free online self-study programs at Fiber U. Many users are preparing for FOA certification programs - taking courses at our schools or using the Direct Certification program. Some of our schools are requiring Fiber U programs as prerequisites for their classroom courses so they can spend more time on hands-on activities.

The Fiber U Design self study program has also been updated for project management.



New Edition of FOA's Basic Fiber Optics Textbook

FOA Reference Guide To Fiber Optics 2024It has been 5 years since we have updated the FOA Reference Guide To Fiber Optics, so it is certainly time for an update. The latest version is different enough we call it a new edition. Many of the updates are for new technologies which are reshaping the fiber optic industry like coherent transmission, BI fibers, etc. We've also added a section on the fiber optic workforce which has much relevance because this book is used to train those entering the workforce.

We've also worked on making the book more readable, adding formatting that eases reading and a new comprehensive index.

The new edition of the FOA Reference Guide To Fiber Optics is available  from Amazon and booksellers worldwide.



Update - 2nd Edition: Fiber Broadband (Paperback and Kindle)

FOA Guide To Fiber BroadbandThis book is not the typical FOA technical textbook - it is written for anyone who wants to understand fiber broadband or fiber optics or the Internet. It's also aimed at STEM teachers who want to include communications technology in their classes. This book will try to explain not only how fiber broadband works, but how it was developed. It is intended to be an introduction to communications technology appropriate for a communications course at almost any level (junior high, high school or college,) for managers involved with broadband projects, or for anyone who just wonders how all this stuff works.

FOA Loss Budget Calculator On A Web Page 5/2020

FOA has written many articles about loss budgets, something everyone involved in fiber optics needs to know and needs to know how to calculate. We recently discovered how to get a spreadsheet ported to a Web page, so we created this web page that calculates loss budgets. We have an iOS loss budget app, but with this web page, you can calculate loss budgets from any device, smart phone, tablet, laptop, or desktop computer that has web browsing capability.

Safety


On Safety

New Fiber U Course: Fiber Optic Safety

fiber USafety must be the first concern of everyone involved in a fiber optic project, including those planning, designing, managing or supervising and of course those doing the installation.

FOA is often asked about safety for fiber optics. Some inquiries ask where it's covered in the FOA Online Guide or textbooks or if we have a course on safety at Fiber U. Almost all Fiber U Courses have lessons covering safety, because safety is important in every aspect of a fiber optic project.

This new Fiber U course will focus on safety alone. There are two lessons in this course, fiber optic construction and fiber optic installation. The dividing line between the two courses is the installation of the fiber optic cables. Construction leads up to and/or is completed when the cables are installed. Installation begins when the fiber tech installs the cable, then completes the splicing, termination testing and documentation. The overlap between the two is the installation of the cables where both construction personnel and fiber optic techs are involved. 

Here is the new Fiber U "Fiber Optic Safety" self-study program. Take the course and get your certificate of completion.

Enhance your safety with the FOA Safety Vest.

FOA Safety Vest


The FOA is concerned about safety!
FOA considers safety an integral part of all our programs, curriculum materials and technical materials. We start all our textbooks and their online versions with a section on safety in the first chapter, like this: Before we get started - Safety First!
 
There are pages on the FOA Guide on Safety procedures Including Eye Safety  and. Digging Safely 

And a YouTube lecture: FOA Lecture 2: Safety When Working With Fiber Optics
 
In our OSP Construction Section, these pages cover many safety issues including those related to the construction of the cable plant: Project Preparation And Guidelines, Underground Cable Construction, Underground Cable Installation and Aerial Cable Installation.
 
There is even a safety poster for the fiber activities: PDF Safety Rules For Fiber Optics
 
Other Safety Resources:

There is a toll-free "call before you dig" number in the USA: Dial 811. See www.call811.com for more information in the US. Here is their map of resources by states.

In Canada, it's "Click Before You Dig.com" They also have a page of resources by US states and Canadian provinces.

The Common Ground Alliance has an excellent "Best Practices Guide" online

The US Department of Transportation has a website called "National Pipeline Mapping System" that allows one to search for buried pipelines.
