Summary

These data describe microbiological analyses performed on groundwater samples from domestic drinking water supply collected from 42 groundwater wells in the Central Valley of California. Samples were collected between January 2014 and April 2014 for the Groundwater Ambient Monitoring and Assessment (GAMA) program priority basin assessment of the Madera, Chowchilla, and Kings (MACK) groundwater sub-basins’ shallow aquifers. A total of 75 wells were sampled for the MACK study unit between August 2013 and April 2014. Samples for this dataset were vacuum filtered and plated on MI and mEI agars prior to incubation to promote colony growth. Colonies were tallied by their species into columns for various fecal indicator bacteria (FIBs): total [...]

Purpose

The purpose of this data release is to distribute supplementary microbiological data collected concurrently with water quality data for the Groundwater Ambient Monitoring and Assessment Program Priority Basin Project Madera/Chowchilla–Kings (MACK) Shallow Aquifer Study Unit of 2014. Primary data for the MACK study unit included a broad array of inorganic and organic constituents and age dating and geochemical tracers that were released in DSR 1019 (Shelton and Fram, 2017) cross referenced to this dataset. This document provides metadata necessary to understand the results included in a comma delineated table (csv file). DNA sequences were created through methods listed in the process steps in the data quality section of this document.
