  • Things to Consider When Visiting Treffry Viaduct As with All Off – Site Visits, a Preliminary Visit from the Class Teacher / Leader Is Highly Recommended
    Things to consider when visiting Treffry Viaduct As with all off – site visits, a preliminary visit from the class teacher / leader is highly recommended. Following on from our workshops here, we have detailed below things we hope you will find useful when planning your visit. Getting to Treffry Viaduct Treffry viaduct is half a mile South East of Luxulyan and approximately 4 miles North of St. Austell. To get a complete sense of the Luxulyan valley and the industrial features there we advise starting the exploration at Pont’s Mill where there is a drop off carpark and walking through the Valley until you reach the viaduct. This will be the end of your journey and is near another small car park outlined below- If you don’t have time to walk up from Ponts Mill or have complications with transport, then you can always start at the viaduct and explore from here. Our experience - the main challenges The Luxulyan Valley and the Treffry Viaduct is a fascinating site that will really make children think about the challenges Joseph Treffry had to overcome in order to achieve his dream at this particular time in history. It is littered with industrial archaeology which will help the children refer back to the game they played on the first day of this project. The Valley, as a natural space is beautiful all year round with plenty of opportunities for the identification and recording of natural species. The main challenges we found when planning a visit were lack of toilets and access for children with mobility issues.

Davies National Rivers Authority Environmental Protection Manager South West R egion ANNUAL CLASSIFICATION OF RIVER WATER QUALITY 1992: NUMBERS OF SAMPLES EXCEEDING TOE QUALITY STANDARD - FWS/93/012 This report shows the number of samples taken and the frequency with which individual determinand values failed to comply with National Water Council river classification standards, at routinely monitored river sites during the 1992 classification period. Compliance was assessed at all sites against the quality criterion for each determinand relevant to the River Water Quality Objective (RQO) of that site. The criterion are shown in Table 1. A dashed line in the schedule indicates no samples failed to comply. This report should be read in conjunction with Water Quality Technical note FWS/93/005, entitled: River Water Quality 1991, Classification by Determinand? where for each site the classification for each individual determinand is given, together with relevant statistics. The results are grouped in catchments for easy reference, commencing with the most south easterly catchments in the region and progressing sequentially around the coast to the most north easterly catchment.

The presentation of all monitoring features into these catchment maps will assist in developing an integrated approach to catchment management and operation. The water quality monitoring maps and index were originally incorporated into the Catchment Action Plans. They provide a visual presentation of monitored sites within a catchment and enable water quality data to be accessed easily by all departments and external organisations. The maps bring together information from different sections within Water Quality. The routine river monitoring and tidal water monitoring points, the licensed waste disposal sites and the monitored effluent discharges (pic, non-plc, fish farms, COPA Variation Order [non-plc and pic]) are plotted. The type of discharge is identified such as sewage effluent, dairy factory, etc. Additionally, river impact and control sites are indicated for significant effluent discharges. If the watercourse is not sampled then the location symbol is qualified by (*). Additional details give the type of monitoring undertaken at sites (ie chemical, biological and algological) and whether they are analysed for more specialised substances as required by: a. EC Dangerous Substances Directive b. EC Freshwater Fish Water Quality Directive c. DOE Harmonised Monitoring Scheme d. DOE Red List Reduction Programme c.
