fine organic debris, and other particulate matter. These
are particles that will not pass through a 2-micron filter.
Higher concentrations of suspended solids can serve as
carriers of toxics, which readily cling to suspended
particles. A high concentration of total solids will make
drinking water unpalatable and might have an adverse
effect on people who are not used to drinking such
water. Levels of total solids that are too high or too low
can also reduce the efficiency of wastewater treatment
plants, as well as the operation of industrial processes
