well-drilling applications; location; GPS

HB 2547 requires well drillers and property owners in Arizona to include GPS coordinates in all new well-drilling applications. The bill mandates that applications must detail the well's exact location via GPS, along with specifications like depth, casing type, and intended water use. For domestic water wells on properties of five acres or less, it adds a requirement for a site plan showing the well's location relative to septic systems and including county health authority approval. This law directly affects anyone seeking to drill or deepen wells in Arizona, standardizing location documentation and adding site plan requirements for small-scale domestic water systems.
