Overview

• EPA data show that over the past five years, 69% of park-run water systems breached drinking water standards, compared with 48% of cities and 57% of larger towns.
• More than half of mobile home parks failed to conduct or properly report at least one required contaminant test during that period.
• Some parks are missing from EPA records, indicating that unregistered sites may escape any federal oversight.
• Federal rules stop at private property lines, allowing contamination from substandard piping inside park boundaries to go undetected.
• Colorado and Utah stand out as the only states with laws that mandate park-wide testing or extend drinking water standards within mobile home communities.
