In rural areas interference on water resources are related to the destruction of permanent preservation areas by the use of pesticides, cattle and inadequate management of their waste. The permanent preservation areas (APPs) are essential in the quest for sustainable development, minimize the impacts of storm action, wind on the ground and ensure the preservation of biodiversity, establishing the balance of the environment. The study aimed to analyze the physical-chemical and microbiological quality of water located in permanent preservation area, intended for animal consumption in producing milk farms in the Taquari Vale region-RS, checking for relationship between water quality and existing native vegetation in these locations. Through activities on site was carried out with the aid of GPS, lifting the corners of rural properties delimiting the elements and demarcating the types of uses and land cover present on the property. The Permanent Preservation Areas were defined based on the current legislation (BRAZIL, 2012). These sites were collected and analyzed water samples by means of physico-chemical parameters (ammonia, color, iron, turbidity, total dissolved solids) and microbiological (total and fecal coliforms) using the potability Alfakit® Kit and fast equipment reading. The results of the water analysis were compared with the maximum value allowed for each parameter set by CONAMA in n° 357/2005 (class 3). It was diagnosed that 33% of the samples conformed to the maximum values allowed by the current legislation regarding water quality and in these areas the percentage of APP covered by native vegetation is less than 50% of the total area. It is concluded that it is necessary to elaborate and execute projects that seek environmental education, to train and raise awareness among rural producers.
