Title:

Groundwater Depletion: How Porous Surfaces and Bioswales Help to Mitigate This Trend

Abstract:

Aquifers all over the world are under tremendous stress due to expanding populations. The improvement in the way of life of millions and the changes imposed on natural watersheds to sustain development are contributors to the reduction of groundwater volumes. Large numbers of individuals get their drinking water from underground sources. Over-exploitation of these resources can have devastating biological, environmental, economical, and social consequences. Use of impervious materials in the construction of cities and roads has prevented large amounts of water to infiltrate the soil in precisely the areas where demand is high. Also some transportation infrastructure projects have greatly disrupted watershed flows preventing water to reach environments that depend on it. The use of Low Impact Development (LID) materials and methods in the design and execution of transportation infrastructure can reduce negative effects on the environment and most important; groundwater resources. Studies focused on the hydraulic, and pollution controlling advantages of these two particular LID strategies show the benefits and potential to reduce the negative impacts development has on the natural water cycle. Porous pavements and bio-swales reduce volume, Peak discharge, and effectively treat important water quality parameters of roadway runoff, while encouraging infiltration. Reducing and for some situations eliminating the need for expensive drainage infrastructure.
