Well Conditions in San Marcos
In San Marcos, wells typically reach depths of 100-300 feet to access the fractured crystalline rock aquifer. The local geology consists of fractured granite bedrock with decomposed granite overlay, which affects drilling methods and well performance.
Common issues we see in San Marcos: low yield wells due to fractured rock, seasonal water table fluctuation. With 12-18 inches annually rainfall, proper well maintenance is essential for reliable water supply.
Water testing in San Marcos focuses on contaminants common to the fractured crystalline rock aquifer, including low yield wells due to fractured rock. We recommend annual testing to monitor for changes in water quality.
