The infiltration approach to stormwater management involves the design, construction, and operation of engineered systems that infiltrate stormwater runoff into soils. These systems, referred to as "infiltration best management practices (BMPs)," are intended to reduce the volume of stormwater runoff and associated pollutants that discharge to stormwater systems and receive waters via surface runoff. The TRB National Cooperative Highway Research Program's NCHRP Research Report 922: Stormwater Infiltration in the Highway Environment: Guidance Manual supports evaluation, selection, siting, design, and construction of infiltration BMPs in the highway environment. It is also intended to identify limitations on the use of infiltration and determine the need for alternative non-infiltration-based stormwater management approaches.

"This textbook is designed for pharmacy technician students enrolled in an education and training program, for technicians reviewing for the national certification exam, and for on-site training and professional development in the workplace. It provides a complete review of the basic mathematics concepts and skills upon which a more advanced understanding of pharmacy-related topics must be built"--
