Do Your Environmental Remediation Systems Meet NEC Codes?

NEC

Selling remediation equipment is not like selling donuts, but both can give you a stomach ache at times. On occasion we receive really good bid documents and drawings, other times it might be a phone call and a sketch. In either case, we can’t just take the bid request at face value and give them what they ask for when we often find critical mistakes in their design.

The Importance Of Public Relations in Geology

I love PR

This guest post was written by our longtime personal friend, Charles R. Livingston.

Whether you consciously think about it or not, you are always involved in public relations when conducting geologic investigations. In addition to the technical skills required to successfully complete a project, the things you say and do (your attitude) can have a significant impact on how well the job goes. The example I am going to give you is something that happened decades ago, and it is just as relevant now as it was then. Some things don’t change much. Good PR is important!

Earth Day and Enviro-Equipment, Inc.: Talkin’ the Talk & Walkin’ the Walk

Earth Day

Although Enviro-Equipment, Inc. (EEI) wasn't around in 1970 when the first Earth Day took place, we have always appreciated that the world comes together one day a year to show appreciation for and commitment to both nature and our planet's environment.

Geologist or Policeman?

Part 5 - Compressors: Rotary Screw, Reciprocating, Rotary Vane, and Rotary Claw

Compressors are used for a number of purposes on remediation projects including:

  • Operation of pneumatic pumps for groundwater extraction or chemical injection
  • Air sparging or bio-sparging where compressed air is injected into the subsurface to remediate petrochemical saturated soil or impacted groundwater
  • Ozone injection where compressed air is used to create ozone for injection
    A number of parameters need to be determined prior to selecting a compressor for a specific purpose.

Some of the typical parameters are as follows:

This article is part five of the "Remediation Secret Knowledge" series which draws upon my personal experiences working in the field with compressors which have a number of uses on remediation projects including:

How Humidity & Cleanliness Affects the MiniRAE VOC Gas Detectors

MiniRAE Humidity Test

Before the MiniRAE 3000 came on the market, Enviro Equipment, Inc. would often receive calls from customers wondering why their PID readings on their MiniRAE 2000 were so high when they were not expecting contamination to be present. The culprit turned out to be high humidity which can drastically affect the readings on a MiniRAE 2000, especially if the white sensor block has been fouled by frequent use without routine cleaning.

SCDHEC Reasonable Rate Document Changes Stir a Hornets Nest

UST Removal

I attended a meeting in August of this year held by The South Carolina Department of Health and Environmental Control (SCDHEC) in Columbia, SC to discuss proposed State Underground Petroleum Environmental Response Bank SUPERB rate changes for Certified UST Site Rehabilitation Contractors.

Testing the MiniRAE 2000 & MiniRAE 3000 Measurement Ranges Using 11.7 eV Lamp

MiniRAE Lamp Test

Many of Enviro Equipment, Inc.’s customers have asked us about the difference between the MiniRAE 2000 and MiniRAE 3000 measurement ranges with an 11.7 eV lamp, so I decided to clarify these differences by conducting my own test.

Optical vs. Electrochemical Dissolved Oxygen Meters

Optical vs Electrochemical Dissolved Oxygen Meters

When testing for dissolved oxygen in the field, an important thing to consider is the type of dissolved oxygen (DO) meter to use. There are several different types of DO sensing technologies, most of which fall under the category of optical or electrochemical sensors. All of these technologies have advantages and disadvantages which must be considered including maintenance, the measurement process, and initial cost.
