To implement the guidance on managing forests in order to minimise adverse impacts in acid-sensitive areas, two categories of acid sensitivity have been identified. These are defined as 'failing due to acidification' and 'at risk of failing due to acidification'. Water bodies identified as currently 'failing' have been classified through the Water Framework Directive monitoring as being of less than 'good' status and the cause of that failure has been attributed to acidification. The 'at risk of failing' water bodies have been identified, via the findings of the Welsh acidification risk assessment, as being at risk of failing to achieve 'good' status by 2027, due to acid deposition. The risk assessment combines chemical and biological data and an assessment of the environment's ability to neutralise the predicted acid pollutants.

Mae Cyrff Dŵr Sensitif i Asid Mewn Perygl Cylch 3 (2022) a Chyrff Dŵr Sensitif i Asid sy'n Methu Cylch 3 (2022) yn setiau data gofodol (ffeil siâp polygon) sy'n cynnwys priodoleddau sydd wedi'u coladu fel y'u diffinnir, ar gyfer gweithredu'r Gyfarwyddeb Fframwaith Dŵr. Er mwyn gweithredu canllawiau ar reoli coedwigoedd er mwyn lleihau effithiau andwyol mewn ardaloedd sy'n sensitif i asid, clustnodwyd dau gategori o sensitifedd i asid. Cânt eu diffinio fel ‘methu oherwydd asideiddio’ a ‘risg o fethu oherwydd asideiddio’. Mae cyrff dŵr a nodwyd fel rhai sy'n 'methu' ar hyn o bryd wedi'u dosbarthu trwy fonitro'r Gyfarwyddeb Fframwaith Dŵr fel rhai o statws is na 'da' ac mae achos y methiant hwnnw wedi'i briodoli i asideiddio. Mae'r cyrff dŵr sydd 'mewn perygl o fethu' wedi'u nodi, trwy ganfyddiadau asesiad risg asideiddio Cymru, fel rhai sydd mewn perygl o fethu â chyflawni statws 'da' erbyn 2027, oherwydd dyddodiad asid. Mae'r asesiad risg yn cyfuno data cemegol a biolegol ac asesiad o allu'r amgylchedd i niwtraleiddio'r llygryddion asid a ragwelir.
