In 1999, we said, “In the past, the emphasis has been on treating “dirty” or contaminated raw water in order to make it safe to drink. As a result, we have developed considerable expertise in terms of drinking water treatment techniques. Now we recognize that much more needs to be done to protect the sources of our drinking water. Better source protection means preventing the kind of pollution that later must be removed or treated, and it means paying more attention to watershed management. It means taking a prevention approach, rather than an end-of-pipe treatment approach. It means being more careful about land use and urban development, about where and how development occurs, and about agricultural uses, including livestock operations. It means protecting the groundwater and surface water in a watershed area. Source protection means taking an ecosystem approach to watershed management — it may also mean a more cost-effective approach to providing clean, safe drinking water over the long haul.” All still needed and more pressing than ever.
