Companies and other entities with legal personality responsible for the treatment and supply of water are concentrated in urban centers, not reaching the rural zone, except for exceptions in locations where urban expansion already borders the rural zone. Considering this fact, the rural population ends up using alternative sources, capturing raw water, which is subject to all sorts of contaminants, whether by human action or natural occurrences. The present work aims to evaluate the parameter of water turbidity directed to the consumption of employees in rural establishments and to indicate the simplest water treatment technology that would shape to improve water quality based on the observed values of turbidity in the laboratory analyzes carried out. . The research had as target population rural employees who use the available water in establishments with more than ten employees, located in the city of Três Corações/MG. The surveys covered three stages: the first, contact and authorizations granted by employers or those responsible for rural establishments; the second for collecting data from the catchment sites with verification of the number of individuals supplied by water and the third for carrying out the collection of water samples and forwarding them to an accredited laboratory. At the chosen catchment sites, water was collected for analysis, covering the turbidity parameter. The evaluations covered sixteen catchment sites, distributed inside eight rural establishments, all of them underground and subsurface water catchments, none of them in a superficial source. Of the population of employees covered in the survey, 82.00% were male and 17.00% female, all of whom were of legal age and 26.72% lived in rural establishments distributed in 48 buildings provided by the employers. The analyzes of the proposed parameter showed that the quality of raw water collected in rural establishments maintained numerical levels of turbidity that would allow direct submission to a disinfection process in 75% of the samples and the other 25% would be subject to treatment by simplified processes in order to improve its quality.
