Water protection plans in Italy

Merli Bill (1948)

Objectives:To regulate discharges

How?•It poses limits of

concentration to principal chemical substances in

wastewater.

Defects:

• It doesn’t consider the rivers flow

•It doesn’t consider biological parameters for

the protection of human health.

So:

In 1999 a low is emanated. It improves the protection of water in

Italy.It is the law n°152

Objectives:

•It considers biological

parameters

•It considers the health of macroinverteb

rate.

In this case , too, the legislation doesn’t consider fish communities, index

of quality for water courses.

But…

Infact:In 2000 a new directive is

emanated:It is the directive 2000/60/CE or European Union Water Framework

Directive.

To value the biological condition of rivers and

lakes.

Objectives:• To value the ecological

condition of water courses and lakes;

It must be analized:•Acquatic flora

•Acquatic invertebrates

•Fish communities

•Morphological elements

We hope that the taken measures can bring wellness to quality of water and that they

can maintain it.
