Policy makers frequently face the problem of evaluating for what reason water quality affects a region's economic well-being. Using water clarity as a measure of the extent of eutrophication levels (as a lake becomes inundated with nutrients, water clarity decreases markedly), analysis is performed upon sales data collected over a six-year period. Our terminates indicate that water clarity has a significant result on prices paid for residential properties. weights of a one-meter change in clarity upon property value are also estimated for an average lake in four real estate market areas in recent Hampshire, with effects differing substantially through area. Our findings provide state and local policy makers a measure of the expense of water quality degradation as measured at changes in water clarity, and demonstrate that protecting water quality may have a positive weight on property tax revenues.

Key Words: eutrophication, hedonics, water clarity, water quality

Between 1986 and 1996 the number of eutrophic lakes (those with high nutrient levels) in of the present day England doubled to 32% (U Environmental Protection Agency, 1997) completely 23% of New Hampshire's lakes have reached the eutrophic stage. It is estimated that cultural eutrophication, to be ascribed to nonpointsource pollution from humans, has increased the rate of eutrophication, with the change in a of New Hampshire's lakes in the last 50 years equivalent to what took place across the previous 10,000 years (Schlos 1999) Eutrophication leads to increased photosynthetic activity, causing algal shooting which can decrease the recreational and aesthetic benefits of the water dead body (Michael, Boyle, and Bouchard, 2000)

Benefit measures of reducing nonpoint-source pollution can minister to two purposes: one is in benefitcost analyses of lake protection programs, and the inferior is to demonstrate to proprietors of lakefront properties that it is in their allow interest to take actions to patronize lakes from eutrophication. Using the hedonic means this study assesses how water clarity affects sale prices of lakefront properties-- adopting conducts identical to those of similar studies examining properties in Maine (Michael, Boyle and Bouchard, 2000; Boyle Poor, and Taylor, 1999)

Despite the similarity in cogitation methodologies, however, we do not reckon upon similar results. New Hampshire lakes are closer to major metropolitan areas as it was as Boston and New York, and, in contrast to Maine, modern Hampshire enjoys a more bring outed highway system. Further, the shorelines of Maine's lakes are substantially les expanded than those of New Hampshire. Finally, Maine's lakes take care of to be considerably larger in succession average than their New Hampshire counterparts.

The noticeable differences of the lakefront housing markets between the couple adjacent states provide opportunities to standard the basic hypothesis that water quality (as measured by means of the proxy of water clarity) is indirectly related to housing prices, and to examine if the purports of water quality on housing markets are affected according to market conditions.

Previous Studies

Only a hardly any studies have been conducted in succession water quality and its powers on property value. Due to the public-goods nature of water bodies, their (mis)use is difficult to monitor. Epp and Al-Ani (1979) estimated the relationship between the value of residential properties adjacent to streams and the quality of the water in the streams. The final example used pH as the environmental variable because it was the in the greatest degree commonly understood measure of quality to the homeowner When the "clean" streams were estimated as a separate dispose the results showed pH had a significant positive import while the polluted streams were unaffected according to pH changes.

Wilman (1984) in her work forward coastal pollution, used market data forward property rentals to discover the richness of beach pollution. The rental price equation included variables for distance from the beach and debris, and a representative for pollution, along with structural and neighborhood characteristics. Wilman place beach debris to be a significant negative factor in rental prices for all housing markets studied.

Young and Teti (1984) studied residential properties in succession St. Albans Bay on Lake Champlain in Vermont Data were mustered from surveys on the basis that consumer are able to perceive changes in water quality, and from market sales data. The water quality variable was set ined as a dummy variable, indicating its location inside or outside the bay. The average characteristic located in polluted areas ofthe bay missing 20% of its value as compared to similar properties located in nonpolluted areas.

More not long ago Michael, Boyle, and Bouchard (2000) investigated the general intents of eutrophication on property values. Changes in chlorophyll of the same heights dissolved oxygen, and water clarity are all ways to measure water quality in lakes where cultural eutrophication may be problematic. Since changes in water clarity are the measure greatest in number likely to be observed by way of the public, secchi disk measurements of clarity were chosen as the water quality variable to be used in the hedonic equation.1 Using the same application, Boyle Poor, and Taylor (1999) were the first to examine a number of separate markets in estimating the demand for water clarity in a State of Maine case contemplation
