The best low-cost options were Hach - https://www.hach.com/ez-series-analyzers/ez-series-arsenic-analyzers/family?productCategoryId=55069943307 and SenseBig http://www.sensebig.com/products/portable-arsenic-analyzer-or-sensor-water-quality-monitoring .

There are several institutions in UK dealing with this aspect especially, Atkins International who did a wonderful job in India for Thermal Power Plants. You may please contact them. All the best.
