Electrical Conductivity Levels by Sub-Catchment (Water Body) Lefelau Dargludedd Trydanol yn ôl Is-ddalgylch (Corff Dŵr)

Ceredigion Coast & Estuaries Chemical Analysis – Electrical Conductivity

Arfordir a Môr-Aber Ceredigion – Dadansoddiad Cemegol – Dargludedd Trydanol

This report analyses chemical levels (Electrical Conductivity) across sampling sites along the Ceredigion coastline and estuaries, grouped by Natural Resources Wales waterbodies (coastal, transitional, river and lake). Values are shown as Electrical Conductivity in mS/cm. Use this report to explore spatial and temporal patterns and compare catchments across marine, estuarine and connected freshwater environments.

Mae’r adroddiad hwn yn dadansoddi lefelau cemegol (Dargludedd Trydanol) ar draws safleoedd arfordirol ac aberol ar hyd arfordir Ceredigion, wedi’u grwpio yn ôl gyrff dŵr Cyfoeth Naturiol Cymru (arfordirol, trosiannol, afonydd a llynnoedd). Dangosir gwerthoedd fel Dargludedd Trydanol mewn mS/cm. Defnyddiwch yr adroddiad i archwilio patrymau gofodol ac amserol a chymharu dalgylchoedd ar draws amgylcheddau morol, aberol a dŵr croyw cysylltiedig.

Sub-Catchment (Water Body) Analysis

Is-ddalgylch (Corff Dŵr)

This section summarizes the spatial and temporal patterns of chemical (Electrical Conductivity) in the Teifi catchments.

  • Readings: Number of chemical measurements collected for each catchment.
  • Median, Min, Max, Mean, Std Dev: Statistical summaries of the chemical values (mS/cm) for each catchment. For catchments with only 1 or 2 readings, these statistics may not be meaningful.
  • Date Range: The period over which samples were collected for each catchment.
  • Note: A warning icon (⚠️) indicates catchments with fewer than 3 readings.

Chemical is measured as Electrical Conductivity in mS/cm. Please refer to NRW or DEFRA guidelines for threshold values relevant to water quality assessment.

Mae'r adran hon yn crynhoi patrymau gofodol ac amserol cemegol (Dargludedd Trydanol) yn nalgylchoedd y Teifi.

  • Darlleniadau: Nifer y mesuriadau cemegol a gasglwyd ar gyfer pob dalgylch.
  • Canolrif, Isafswm, Uchafswm, Cyfartaledd, Gwyriad Safonol: Crynodebau ystadegol o werthoedd cemegol (mS/cm) ar gyfer pob dalgylch. I ddalgylchoedd gyda dim ond 1 neu 2 ddarlleniad, efallai na fydd ystadegau hyn yn ystyrlon.
  • Ystod Dyddiad: Y cyfnod y casglwyd samplau ar ei hyd ar gyfer pob dalgylch.
  • Nodyn: Mae eicon rhybudd (⚠️) yn nodi dalgylchoedd gyda llai na 3 darlleniad.

Mesurir cemegol fel Dargludedd Trydanol mewn mS/cm. Cyfeiriwch at ganllawiau NRW neu DEFRA ar gyfer gwerthoedd trothwy sy'n berthnasol i asesu ansawdd dŵr.
