===Hydro-geology ===
Rivers in the region are fault guided meaning that they flow is highly influenced by a structural weakness called a fault. Several natural springs occur in the highland regions with a neutral to slightly acidic ph values. Natural [[groundwater]] levels varies from {{convert|10|m|ft|round=5}} below the Taibach area of Port Talbot to over {{convert|20|m|ft|round=5}}. Rivers in the region including the River Afan (Aberafan), River Neath (Baglan Bay), [[Nant Ffrwdwyllt|Ffrwdwyllt]] (Taibach), Arnallt Brook (Taibach), Baglan Brook (Baglan), River Kenfig (Morfa Beach) and other rivers are fast flowing and are highly influenced by their mouths (end of the rivers, tidal region). A spout can be found in Baglan Park in the Baglan region of Port Talbot. Many open and uncovered reservoirs exist in the region. Water has been channelled into ditches in industrial areas of Port Talbot.<ref name="autogenerated1"/><ref>Ordnance Survey Map, Port Talbot Region,2011</ref>
