Among the functions of evaluation, the control and environmental monitoring of the uses of existing water sources in Cesar was studied by the Corporación Autónoma Regional del Cesar, CORPOCESAR, to evaluate the quality of groundwater located in 93 wells in the municipalities of La Paz and  San Diego (Cesar) in 2009 in accordance with decree 1575/07 and resolution 2115/07 of the Ministerio de Protección Social (Ministry of Social Protection) and the Ministerio de Ambiente, Vivienda y Desarrollo Territorial (Ministry of Environment, Housing and Territorial Development). Were characterized microbiological properties (determined from Psuedomona aeruginosa and protozoan pathogens) and physiochemical properties (conductivity, pH, temperature, total dissolved solids, salinity, acidity, basicity, turbidity, chlorides, ammonia, nitrites, iron, magnesium, sodium and calcium; the last three elements being necessary for the calculation of the viability of irrigation, with the end of quantifying the quality of the water supplying the inhabitants of these lands). The Detection of P. aeruginosa was achieved via filtration through a membrane and protozoa through the flotation technique by centrifugation with zinc sulfate. Of the samples analyzed, 84.94% contained P. aeruginosa. Were identified five genera of protozoa, Giardia sp being the pathogen of highest prevalence at 46.1 %, followed by Cryptosporidium sp at 22.18%. Respecting the physiochemical results, only 4.3% of the wells sampled were determined to be suitable for irrigation without jeopardizing public health and safety.
