Qualifications

Experience requirements are described in the Office of Personnel Management (OPM) Qualification Standards for General Schedule Positions, Professional and Scientific Positions. BASIC REQUIREMENT OR INDIVIDUAL OCCUPATIONAL REQUIREMENT: Degree: physical or natural science, or engineering that included at least 30 semester hours in any combination of courses in hydrology, the physical sciences, geophysics, chemistry, engineering science, soils, mathematics, aquatic biology, atmospheric science, meteorology, geology, oceanography, or the management or conservation of water resources. The course work must have included at least 6 semester hours in calculus (including both differential and integral calculus), and at least 6 semester hours in physics. Calculus and physics, as described above, are requirements for all grade levels. OR Combination of education and experience -- course work as shown in A above, plus appropriate experience or additional education. Evaluation of Experience: Acceptable experience must have included performance of scientific functions related to the study of water resources, based on and requiring a professional knowledge of related sciences and the consistent application of basic scientific principles to the solution of theoretical and practical hydrologic problems. The following is illustrative of acceptable experience: field or laboratory work that would require application of hydrologic theory and related sciences such as geology, geo-chemistry, geophysics, or civil engineering to making observations, taking samples, operating instruments, assembling data from source materials, analyzing and interpreting data, and reporting findings orally and in writing. In some cases, professional scientific experience that is not clearly water resource experience may be acceptable if such experience was preceded by appropriate education in hydrology or by professional hydrology experience. Applicants with related experience in hydrology gained through earlier Federal Government employment might have gained that experience in one or more occupational series. Such series include Soil Conservation, GS-457; Forestry, GS-460; Soil Science, GS-470; Civil Engineering, GS-810; Chemistry, GS-1320; Meteorology, GS-1340; and Geology, GS-1350. Comparable non-Federal experience may be given similar credit. In addition to meeting the basic requirement above, to qualify for this position you must also meet the qualification requirements listed below: SPECIALIZED EXPERIENCE: Applicants must have at least 1 year (52 weeks) of specialized experience at the next lower broadband NH-02, equivalent to the next lower grade GS-11 or equivalent in other pay systems. Specialized experience must include technical expertise in designing and optimizing remediation strategies for complex sites-particularly those impacted by emerging contaminants like PFAS-combined with the project management capability to oversee external technical contractors, and the professional authority to represent the organization at national regulatory, interagency, and industry environmental forums. NOTE: Due to the use of 120-day rosters, this period of experience may be completed within 120 days of the closing date of this announcement.
