Saturna Island Well Depths & Groundwater Data (204 Wells)

Bottom Line Up Front

In SATURNA ISLAND the median well is 250 feet deep and draws from Unknown bedrock, which supplies 107.4% of wells here. Water is very hard at about 325 mg/L, so a softener is standard equipment. Rotary drilling is routine and 94% of wells serve ordinary household use. Treatment emphasis: standard regional mineral profile. Local sampling should confirm the unresolved formation profile.
