This dataset contains details pollution incidents reported to Natural Resources Wales (NRW). Only substantiated and closed environmental protection incidents are included. Where these data indicate an incident occurred on a particular site or property no inference should be drawn that the site or property owner necessarily was responsible.

Mae'r set ddata hon yn cynnwys manylion digwyddiadau o lygredd mae CNC yn cael eu hysbysu amdanynt. Dim ond digwyddiadau diogelu amgylcheddol sydd wedi cael eu cadarnhau ac sydd wedi cau sy'n cael eu cynnwys, lle mae'r lefel o effaith amgylcheddol naill ai yng Nghategori 1 (mawr) neu Gategori 2 (sylweddol) ar o leiaf un cyfrwng (h.y. dŵr, tir neu aer).


Lle mae'r data hwn yn dangos digwyddiad ar safle neu eiddo arbennig, ni ddylid casglu o anghenraid mai'r safle neu'r perchennog oedd yn gyfrifol.
