Wellwaterology

Wellwaterology: Which One Is Yours? is an educational guide to private well water systems written by Eric Koslowski, the founder and longtime laboratory director of ETR Laboratories. Drawing on more than 40 years of hands-on experience in water quality science and testing, Koslowski walks readers through how private well systems actually work, from raw groundwater sources through the well itself and into the home, with a focus on contamination pathways and what well owners can do to protect their water supply.

The book is written for homeowners rather than scientists. The goal is practical understanding over technical detail, giving readers a solid foundation for making informed decisions about their well water and the health of their household.
