The Challenges of Stormwater Management   Water Engineering & Management November 2002   Bryan A. Coppes
Stormwater management and its role in the larger challenge of preservation of water quality around the world is an evolving issue. As commercial development continues at record levels, both the quantity of runoff and water quality are issues that need to be looked at carefully. The engineering community is being pushed to design new solutions that keep groundwater and surface water ecology safe and that also protect development economics.

Effects of Recharge of Chlorinated State Water Project Waters to Groundwaters in Lancaster Area of California   Water Engineering & Management April 2002   Hisam A. Baqai, P.E., G.E.
As the population in Southern California increases, more and more demands are being put on the state’s groundwater resources, further exacerbating the overdraft problem. Many communities in Southern California are recharging their aquifers with imported surface waters to combat this problem. The major recharge normally is carried out during wet weather periods when surface water is plentiful. However, recharging these groundwater aquifers with imported surface water can create the potential for water quality degradation. The problem can start when surface water is disinfected with chlorine to prevent biofouling and remove pathogens.
