Slow sand filters do not need constant operator attention, making them an appropriate technology for water systems that are small or that employ part-time operators. During the 1970s through the 1990s, research and field evaluations of slow sand filtration have demonstrated its efficacy for control...

Simultaneously, distance-related indicators show that the closer the relative distance between ponds and agricultural land within the watershed, the better the overall water quality (Fig. 4 and Table 3). This indicates that the ponds can maximize their filtration and buffering "sink function" when ...

Of survey respondents, 97 percent of surface water systems and 86 percent of groundwater systems provided disinfection. Among surface water systems responding, 94 percent provided filtration. Survey data suggest that most systems will be able to comply with Stage 1 Disinfectants/ Disinfection By-...
