Chloride/bromide ratios in leachate derived from farm-animal waste.
Abstract: Ratios of conservative chemicals have been used to identify sources of groundwater contamination. While chloride/bromide ratios have been reported for several common sources of groundwater contamination, little work has been done on leachate derived from farm-animal waste. In this study, chloride/bromide ratios were measured in leachate derived from longhorn-cattle, quarterhorse, and pygme-goat waste at a farm in Abilene, Texas, USA. (Minimum, median, and maximum) chloride/bromide ratios of (66.5, 85.6, and 167), (119, 146, and 156), and (35.4, 57.8, and 165) were observed for cattle, horses, and goats, respectively. These ratios are below typical values for domestic wastewater and within the range commonly observed for oilfield brine. Results of this study have important implications for identifying sources of contaminated groundwater in settings with significant livestock and/or oil production.

The research conducted in this article involves exploring the chloride/bromide ratios in leachate that comes from farm-animal waste in an effort to better detect sources of groundwater contamination. The specific animals examined are longhorn-cattle, quarterhorse, and pygme-goat on a farm in Abilene, Texas.
Objective of the Research
- The main objective of this study was to measure and analyze the chloride/bromide ratios in leachate derived from different farm animals’ waste. This is significant for identifying sources of groundwater contamination, particularly in areas with considerable livestock farming or oil production.
Methodology
- Research was conducted on a farm in Abilene, Texas, USA, where samples from three types of farm animals were collected: longhorn cattle, quarterhorse, and pygme-goat.
- From these samples, the chloride/bromide ratios were examined. The minimum, median, and maximum values of these ratios were gauged for each type of animal.
Results and Findings
- For the longhorn cattle, chloride/bromide ratios varied from 66.5 to 167, with a median of 85.6.
- The quarterhorse showed ratios from 119 to 156, the median being 146.
- And the pygme-goat demonstrated ratios from 35.4 to 165, with a median of 57.8.
- All these ratio values were discovered to be below the typical ones for domestic wastewater but being in the range commonly seen for oilfield brine.
Significance of the Study
- The results of this study are significant for environmental science, particularly for identifying contaminants in groundwater sources. These findings can be used to distinguish between contamination arising from livestock waste and that emerging from other sources like domestic wastewater or oilfield brine.
- Given that these results differ notably from the typical values seen in domestic wastewater, and are within the range for oilfield brine, the implications of this research are especially valuable in settings where there is a mix of livestock farming and oil production.
