Residents of Lisbon who want to use the Estoril Coast beaches would be willing to pay $4,439 per person to avoid getting gastroenteritis from polluted water, indicating that the total health risk cost of bathing water pollution at the Estoril Coast is between $7.1 and $19.6 million. Using stated preference techniques, a 2002 study at the Estoril Coast, found that the aggregate recreational cost of pollution was $10.3 and $50.6 million for `average' and `bad' water quality levels respectively. Adding these purely recreational costs to the actual health risk cost estimates of bathing water pollution ($7.1± 19.6 million) yields an estimate of the yearly total costs of water pollution at Estoril Coast beaches of $68.5 ± $79.9 million. http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6WJ7-46MJTG9-1&_user=10&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_version=1&_urlVersion=0&_userid=10&md5=35e009811025fcee253714e9004c640a
