Six months of general experience and 6 months of specialized experience equivalent to at least the GS-3 level in the Federal service that is in or related to the duties of this position. NOTE: Excess specialized experience beyond the required 6 months may be substituted for general experience; i.e., one year of creditable specialized experience will meet the requirements for 6 months of general experience and 6 months of specialized experience. General experience is any type of work that demonstrates the applicant's ability to perform the work of the position to be filled, OR experience that provided a familiarity with the subject matter or processes of the broad subject area of the occupation for which the applicant is applying.

Specialized experience may include work as a technician or aid in engineering, earth, physical, or natural science, forestry, soil conservation, or surveying; trades or crafts work in maintenance or construction of facilities or equipment related to hydrology; drafting; or construction estimating if it equipped the applicant with the knowledge, skills and abilities to perform successfully the duties of this position.

Examples of GS-3 level work assignments include: 1) Performing minor repairs at gaging stations, to water level recorders and other equipment used in hydrologic investigations; 2) Assisting in making measurements of stream flow or making simple current meter measurements on small streams; 3) Recording routine measurements of water levels at specified observations wells; 4) Collecting water quality samples and assisting in making laboratory determinations of water quality parameters by predetermined methods; 5) Maintaining and assisting in readying current meters and sampling equipment for field work. For examples 1-5, a designated authority made assignments by giving complete, explicit oral and/or written instructions at the beginning of each assignment, covering work methods, available equipment, procedures, reference guidelines, etc. Recurring assignments were carried out within well-established procedures, with minimal instruction and were only infrequently spot checked or observed by a designated authority. Less routine assignments were occasionally checked in progress or upon completion.

**OR applicants may substitute successful completion of two full years of study that included at least 12 semester hours, or the equivalent, in any combination of courses such as engineering, industrial technology, construction drafting, surveying, physical science, biology, or mathematics.

**OR a combination of successfully completed post-high school education and specialized and/or general experience may be used to meet the qualification requirements for the GS-04 level. NOTE: When crediting education to meet any part of the experience requirement, such education must include the appropriate number of directly related credit hours required in any combination of courses such as engineering, industrial technology, construction drafting, surveying, physical science, biology, or mathematics. When crediting this education, you must prorate the number of hours of directly related courses required as a proportion of the total education to be used.

For GS-05:

Applicants must meet one of the following to qualify for the GS-5 level:

One year of specialized experience equivalent to at least the GS-04 level in the Federal service that is in or related to the duties of this position. Specialized experience may include work as a technician or aid in engineering, earth, physical, or natural science, forestry, soil conservation, or surveying; trades or crafts work in maintenance or construction of facilities or equipment related to hydrology; drafting; or construction estimating if it equipped the applicant with the knowledge, skills and abilities to perform successfully the duties of this position.

Examples of GS-4 level work assignments include: 1) Making adjustments and minor repairs to water level recorders, or other equipment used in water investigations; 2) Following well-defined methods and designated formulas; computing, extracting, compiling, and presenting geological or hydrologic data in prescribed tabular or graphic form; 3) Computing mean daily gage heights from water stage record charts, editing record tapes, and making corrections based on field notes. For examples 1-3, the work assignments involved familiar conditions, concepts, and methods that were made in terms of the objectives to be achieved without explicit instruction as to work methods. Assignments involving new, more difficult, or unfamiliar areas of work were given with more specific guidance. Explicit instructions were provided for solving technical problems involving unfamiliar conditions, methods, or concepts.

**OR Applicants may substitute successful completion of a full four year course of study leading to a bachelor's degree (a) with major study in an appropriate field of science (i.e., geology, chemistry, physics, geophysics, biology, ecology, mathematics, soils, forestry, meteorology, hydrology, oceanography, physical science, atmospheric science) engineering, construction, or industrial technology, or (b) that included at least 24 semester hours, or the equivalent, in any combination of courses such as engineering, industrial technology, construction drafting, surveying, physical science, biology, or mathematics.

Education

Examples of GS-05 level work assignments: 1) Computing mean daily gage heights from water stage record charts, editing record tapes, and making corrections based on field observation notes; 2) Preparing maps showing well elevations and depth to water, hydrographs, profiles, and well locations. For examples 1-2, the work assignments involved some technical problems not previously encountered; problems involving concepts and methods for which guides and precedents existed, were resolved independently.

Other examples of GS-05 level work assignments include: 1) Installing, adjusting, inspecting, and servicing crest-stage indicators, well-recorders, and other instruments for the collection of ground and surface water data; and checking gage settings to ensure continuing accuracy of the records obtained from instruments; 2) Making technical studies of hydrologic data collected in the field, and preparing material for publication, such as, drafts, maps and other illustrative material; applying datum corrections to gage height records allowing for periods of ice effect, temperature variations, and precipitation; and plotting hydrographs and analyzing differences in hydrographs with earlier records, and making necessary changes. For examples 1-2, routine assignments that involved familiar conditions, concepts, and methods were made in terms of the objectives to be achieved without explicit instruction as to work methods. Assignments involving new, more difficult, or unfamiliar areas of work were given with more specific guidance. Explicit instructions were provided for solving technical problems involving unfamiliar conditions, methods, or concepts.

**OR applicants may substitute successful completion of 1 year of appropriate graduate level education (18 semester hours, 27 quarter hours or the equivalent) in hydrology or other field of study directly related to the work of this position for the required 1 year of specialized experience if it provided the knowledge, skills, and abilities necessary to perform the work of this position.

**OR applicants may substitute a combination of appropriate specialized experience (as described above) and appropriate graduate level education (as described above) that is beyond the first 1/2 year of progressive graduate study to meet the qualification requirements.

You must meet all qualification and eligibility requirements for the position by the closing date of the announcement.

EDUCATION Experience refers to paid and unpaid experience, including volunteer work done through National Service programs (e.g. Peace Corps, AmeriCorps) and other organizations (e.g., professional; philanthropic; religious; spiritual; community; student; social). Volunteer work helps build critical competencies, knowledge, and skills and can provide valuable training and experience that translates directly to paid employment. You will receive credit for all qualifying experience, including volunteer experience.
