The report describes the investigation of the nitrate contamination in Runnels County, Texas. It was found that most water well contamination is due to naturally occurring nitrate. However, all the very high nitrate contamination problems (>1000 ppm) are principally due to nitrate from barnyards. The nitrate sources were confirmed using the nitrogen isotope ratio technique. The nitrate contamination was caused by a rising water table which intersected and dissolved nitrate deposits from the soil. The rising water table was caused by a combination of low porosity aquifers, increased infiltration (decreased surface runoff) due to terracing, and several consecutive years of above normal rainfall. There appears to be no economical way to remove the nitrate from either the water or the soil. Recommendations for ways for the area residents to obtain potable water and for a continued monitoring program are included. (Modified author abstract)
