The water treatment specialist is the person who typically performs water sample collection and analysis, and diagnoses water quality problems such as water hardness, mineral staining, low or high pH, or the presence of taste and odor. This professional may be employed by a groundwater contractor or a company specializing in water treatment of both groundwater private and public water supplies. Groundwater contractors offering water treatment services usually have an advantage over those who only specialize in treatment, as they are usually able to recognize and differentiate between water quality issues and well health issues.
 
As with most skills and professions, training and instruction may be available through associations and post-high school studies.
 
Once the diagnosis has been made and the proper equipment or technique of treatment has been decided upon, the equipment must be installed. Larger companies employ individual technicians who specialize in installations, maintenance and service, and sales. Meanwhile, the staff of smaller companies may wear several suits.
