Working Conditions and Physical Requirements

This role is physically demanding and relies on individuals who enjoy working with their hands, moving actively, and tackling mechanical challenges. You can expect to encounter:

• Heavy Lifting: Daily operations require regularly moving equipment, valves, and chemical supplies weighing between 45 and 50 pounds, with occasional heavier lifting required.
• Environmental Exposure: The job demands working both indoors and outdoors, exposing you to all forms of Maryland weather. You will operate in environments featuring noisy running machinery, loud motors, and low-ventilation zones.
• Chemical and Biological Safety: Because you will work directly with toxic agents like methane, chlorine, and acid, as well as biological pathogens, you must consistently wear comprehensive protective equipment. This includes gas masks, full face shields, respirators, and acid-resistant clothing.

Crucial Application Tips to Prevent Disqualification

Federal hiring is unique and highly structured. A minor mistake on your application can prevent human resources from considering your package. Pay close attention to these vital requirements:

• The Two-Page Resume Rule: Your resume must be two pages or less. If your resume is even one page longer, it will be immediately removed from the applicant pool without a review of your qualifications.
• Explicit Licensing Details: Since licensing is an absolute requirement, you must attach a clear, scan-ready copy of your current wastewater credentials or operator licenses. Failing to do so results in a rating of "ineligible."
• Quantifiable Work History: For each job listed, write out your exact hours worked per week, the company name, your formal job title, and precise start/end dates (Month and Year). Without this, HR cannot calculate your years of specialized experience.
• Clear Language: Avoid internal military jargon, company-specific codes, or confusing acronyms. Write details simply and clearly to prove you possess the necessary skills.
