    average of nitrates ≥50 mg/dm3
    – water polluted,

this same village). Also the average value for Poland is actually lower than the value from an earlier period. Today is

However between 2020 a 2023 year. there was a significant increase in the number of inspections: conducted by ARiMR from 3 758 to 12 657 and by WIOŚ from 1 412 to 2 005.
