Mae wedi dod i’r amlwg bod y tir hwn wedi effeithio ar 16 o gartrefi ar yr ystad. Yn ôl ymchwiliadau a gynhaliwyd yn gynharach eleni, mae crynodiadau uchel o arsenig a phlwm o dan yr eiddo a fyddai'n gallu peryglu iechyd pobl.
Contaminated land has been found to affect 16 homes on the estate. Investigations  earlier this year found high concentrations of arsenic and lead underneath the properties which could pose a risk to human health.
