• Hydraulic Properties . Aquifer Testing 101

    Aquifer tests (pumping tests slug tests and constant-head tests) are performed to estimate site-specific values for the hydraulic properties of aquifers and aquitards. Under certain circumstances however site-specific hydraulic property data may not be available when needed. For example reconnaissance studies or scoping calculations may require hydraulic property values before on-site
