| Notes: Analytes detected above laboratory detection limits are shown in bold font. All well water samples were collected through well pump or via bailer. Duplicate sample results in Table 8.2-4 apply to Table 8.2-5 and Table 8.2-6. * Chlorination byproducts in water supply well (referenced in SDWA drinking water regulations as THMs or trihalomethanes). MCL for total concentration of THMs is 100 ug/L. NS = not sampled | ||||||||||
