Study Background • Methane (CH 4 ) Prevalence and Variability ‣ Lack of water well construction standards ‣ General findings from extensive pre‐drill data • Water well samples collected (2009‐2011): 11,312 • Methane detections (>0.026 mg/L): 2,740 (24.2%) >0.026 to 3 mg/L: 2,064 (18.2%) >3 to 7 mg/L: 287 (2.5%) >7 to 20 mg/L: 270 (2.4%) >20 mg/L: 119 (1.1%) ‣ Limited understanding of natural methane variation and occurrence related to complaints
Long-Term Monitoring: Domestic Wells • Address gaps in understanding • Quantify natural variation in methane levels Relevance • Significant importance in assessing natural methane variation and occurrence Study Objective • Gain understanding of long‐term variability of methane in domestic water wells and correlation to other parameters, such as well usage and pumping
